Description of the Invention: [Technical Field] The present invention relates to an auxiliary pad structure of a machine tool, and more particularly to an auxiliary pad structure applied to a machine tool to support an operator's hand. [Prior Art] [0002] Because of its small size, low price, and the ability to connect different application tools, the machine tool can be formed into various types, such as grinding discs, grinders, drilling machines, and electric wrenches. It is very popular to assist operators in performing certain work procedures quickly. In addition to electric power-driven power tools, pneumatic tools are also used that are driven by a pressure body. [0003] At present, the common machine tools in the industry, such as a grinder, can be referred to the Patent No. M261316 of the Republic of China. The machine tool disclosed in the above patent case mainly has a body, and the body extends out of a grip portion on the grip portion. a driving button is disposed, and a control rod contacting the driving button is pivoted, and the body is internally provided with a motor and a tool shaft connecting the motor, and the user presses the lever during operation to make the lever The drive button is pushed to drive the motor to operate with the tool shaft, thereby causing the actuator connected to the tool shaft to rotate to process the workpiece. [0004] However, the above-mentioned machine tool is mainly operated by pressing one end of the control lever with the front half of the palm and holding the body of the machine tool with fingers, while the rear half of the palm is suspended; In the posture, the user's hand is forced by the hanging state for a long time, which may cause fatigue of the user's hand, and may cause muscle or joint pain if it is slightly inadvertent. In order to improve this problem, relevant operators have developed a supportable user's hand 099129390 Form No. A0101 Page 3 / Total 15 Page 0 [0005] 201210737 Department of Machine Tools' such as US Dijon 2〇1〇/〇18〇714 No. Patent Publication No., the machine tool disclosed in the patent is substantially the same as the conventional machine tool, and has a lever pivoted on the machine tool, in particular, the lever is pivoted. When the two ends of the position respectively form a front end portion and a rear end portion, the user can press the front end portion of the control rod to the front half of the palm and the rear half of the palm can abut against the rear end portion of the control rod. This provides the function of supporting the hand. [0006] However, the operation mode is like a seesaw, please refer to "Figure 2 and Figure 2". When the rear half of the palm rests on the rear end 103 of the control lever 1〇1, the control lever 1前ί's front quilt 1〇2 will rise due to the principle of leverage, causing the machine tool 100 to not function properly (as shown in Figure )); and when the front half of the palm presses the front end of the lever 101 1〇2 At this time, the rear end portion 1G3 of the lever 1〇1 is also raised by the lever principle, so that the hand of the player is raised by the rear end portion 103, and proper support cannot be obtained (as shown in FIG. 2). Therefore, the above-mentioned patent _ can not be used to control the function of the user's hand while the machine tool m is operated. SUMMARY OF THE INVENTION [0007] The purpose of the county of the present invention lies in the material (four) material, so that the secret from 丫I her rS·, benefit to: r eye secret. There is a working machine when the machine tool is running Stable support is available from all. In the state of non-operational state [0008] 099129390, the machine tool has a grip portion and a driving switch, and the grip portion is further provided with a control unit disposed on the grip portion, and the lever has a pivoting stroke, and in the pivoting line, the '" two-system driving switch, 201210737, and the auxiliary pad is disposed on the grip portion, and forms a gap with the control rod, the auxiliary pad has a The support surface is inclined upward from the end adjacent to the control rod toward the other end. [0009] According to the above technical solution, 'there is a gap formed between the auxiliary pad and the control rod, so that the control rod and the auxiliary pad do not interlock or interfere with each other, so when the control lever is pressed or released, The auxiliary pad can maintain a fixed angle of inclination to provide stable support. [Embodiment] 0 [0010] The detailed description and technical contents of the present invention will now be described with reference to the following figures: [〇〇11] Please refer to "Fig. 3 and Fig. 4", the present invention is a machine tool The auxiliary pad structure includes a machine tool 1 and an auxiliary pad 30 disposed on the machine tool 10; the machine tool 10 can be a grinder, and the machine tool 10 is extended on the body for the user to The grip portion 11 is disposed, and the grip portion 11 is provided with a driving switch 14 and a button portion 12, and a pivot rod 13 is disposed with a control rod 15 and the hinge portion 12 to make the lever portion 15 The pivoting stroke is generated by pivoting the grip shaft 11 ' and the shaft 13 is pivoted and the lever 15 is pressed in the pivoting stroke to drive the inside of the machine tool 10 The motor (not shown) operates. [0012] 099129390 In addition, as shown in FIG. 5, the power tool 1 is provided with a heat sink 20 on the grip portion u. The heat sink 20 is made of a heat conductive material and has a plurality of heat dissipation fins 21 The heat in the grip portion 11 can be conducted outward, thereby achieving a heat dissipation effect. In addition, the heat sink 2 is provided with a carrying portion 22 for mounting the auxiliary pad 30, wherein the carrying portion 22 and the auxiliary frame 3 are respectively provided with a first fixing portion 23 and a second fixing. Section 31, Form No. 1 W Page/Total 15 Stomach 0992051590-0 201210737 As shown in the figure, the first fixing portion 23 and the second fixing portion 31 may be mutually interlocking hooks; in the present invention, The auxiliary pad 3 is not limited to the heat sink 2〇, but may be directly disposed on the handle portion 11 and the auxiliary pad 30 is spaced apart from the control rod 15 to make the auxiliary pad A gap d is formed between the 30 and the control rod 15, and the auxiliary pad 3 is provided with a floor 32. The support surface 32 is inclined upward from the end of the control rod 15 toward the other end to allow the user to operate. When the hand rests on the support surface 32' and the support surface 32 is ergonomically designed to form an inwardly concave curved surface to conform to the contour of the user's hand, the support surface 32 may also be non-radial. The inclined surface of the supporting surface 3 2 has a sliding line 3 3 to increase the stability of the support and prevent operation The hand slides away from the support surface 32 due to vibration, and the auxiliary pad 30 can be a flexible body, such as a rubber, which can be used to absorb the vibration of the machine tool 10 during operation and provide proper cushioning of the hand. Referring to FIG. 6 , a gap d is formed between the auxiliary pad 30 and the control rod 15 . When the user presses the control rod 丨 5 , the control rod 15 and the auxiliary pad 30 do not interfere with each other. Sustainable support for the user's hands. [0013] In summary, the present invention mainly provides an auxiliary cymbal 30 on the grip portion 11 of the machine tool 10 provided with the control rod 15, and the auxiliary cymbal 30 has a support surface 3 2 ' It is worthwhile for the user's hand to form a gap d between the auxiliary pad 30 and the control rod 15, and the supporting surface 32 is inclined upward from the end close to the control rod 15 toward the other end. In this way, when the user operates, whether or not the control cymbal 15 is pressed, the auxiliary cymbal 30 can maintain a fixed inclination angle 'not affected by the control rod 15, allowing the surface 32 to be stabilized by the hand. The ground is pressed against the auxiliary pad 30. 099129390 Form No. A0101 Page 6 / Total 15 Page 0992051590-0 201210737 Relieve and relieve hand fatigue. The above is only the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, that is, the equivalent changes and modifications of the content of the patent application of the present invention should be the technology of the present invention. category.
