A kind of head resilient mountingTechnical field
The present invention relates to a kind of electric cutting tool, be specifically related to a kind of resilient mounting of electric cutting tool.
Background technology
At present, electric cutting tool is widely used in machining and manufacture field.Diagonal cutting saw is one of the most common electric cutting tool.Diagonal cutting saw comprises head and body, in use, when needing to cut workpiece, as long as press down head, saw blade can be driven to cut workpiece; After cutting, head resilience.Diagonal cutting saw of the prior art, generally adopt torsion spring to make head resilience, and torsion spring relies on its torsional elasticity to produce frictional force to transmit the spring of power or motion.So, adopt torsion spring to make head resilience, usually also by external force, will make troubles to operation.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides a kind of than torsion spring resilience easier head more easily resilient mounting.
Technical scheme: for solving the problems of the technologies described above, head resilient mounting of the present invention comprises body, head and stage clip, and described body is provided with body and supports, and body is provided with alignment pin on supporting; Described head is provided with the sleeve for placing stage clip, the top of described stage clip and the contact internal walls of upper cartridge, fixture is adopted to be fixed in sleeve by stage clip top, the bottom of stage clip is provided with stage clip holder, makes the contact surface of the bottom of stage clip holder and alignment pin for contact completely by extruding stage clip.
Wherein, described fixture comprises pressing plate and the hex screw for fixation clip.
Stage clip, bear the helical spring to pressure, because can pressure be born, two ends can be open type or enclosed or around flat or polish, its material section used mostly is circular, and also useful rectangle and multiply steel are entangled and rolled, and spring has equal pitch and pitches, the shape of Compress Spring has: the variant of cylindrical, conical, camber and middle concave and a small amount of non-circular and even various tail end, all can be shaping according to design according to product needed.Have certain gap between the circle of stage clip and circle, when being subject to external applied load, spring contraction distortion, stores deformation energy.
Beneficial effect: head resilient mounting of the present invention, conventional torsion spring is replaced to make head resilience by adopting stage clip, and adaptive improvement is carried out to the structure of body and head, head can be put in place more easily in resilience: when head is depressed into certain position, unclamp both hands, remove external force, the resilience of the rebounding ratio torsion spring of stage clip is easier, easily.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described.
As shown in Figure 1, head resilient mounting of the present invention comprises body 2, head 1 and stage clip 6, and described body 2 is provided with body and supports 3, and body supports on 3 and is provided with alignment pin 4; Described head 1 is provided with the sleeve 5 for placing stage clip 6, the top of described stage clip 6 and the contact internal walls on sleeve 5 top, fixture is adopted to be fixed in sleeve 5 by stage clip 6 top, the bottom of stage clip 6 is provided with stage clip holder 7, make the contact surface of the bottom of stage clip holder 7 and alignment pin 4 for contact completely by extruding stage clip 6, be also called full contact.Wherein, described fixture comprises pressing plate 8 and the hex screw 9 for fixation clip 8.Stage clip 6 in the present embodiment is cylindrical stage clip.
The present invention in use, when head 1 is depressed into certain position, unclamps both hands, removes external force, and the resilience of the rebounding ratio torsion spring of stage clip 6 is easier, easily.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
