可调式扳手adjustable wrench

[技术领域][technical field]

本发明是关于一种扳手，特别是关于一种可调式扳手。The present invention relates to a wrench, in particular to an adjustable wrench.

[背景技术][Background technique]

在传统产业中，手工具产品占有大量的外销市场，其必须在品质、实用性及良好操作性等方面均占有优势，才能抢占外销的市场，而手工具的制造方式及过程直接与成本及生产速度息息相关，这也是现今提高手工具市场竞争力的重要环节。In traditional industries, hand tool products occupy a large number of export markets. They must have advantages in quality, practicability, and good operability in order to seize the export market. The manufacturing method and process of hand tools are directly related to cost and production. Speed is closely related, which is also an important link to improve the competitiveness of hand tools market today.

而如图1所示，为美国专利第5,415,064号的扳手结构图，其显示一扳手100具有一夹持部101，夹持部101具有一夹持槽102及一调整槽103，该夹持槽102具有第一、二夹持面104、105；一调整块106容纳在调整槽103，并受一调整螺杆107穿伸，而该调整螺杆107一端伸入夹持槽102；一活动块108是位于夹持槽102内，并与调整螺杆107该端螺合，而藉旋转调整块106，使活动块108顺着调整螺杆107轴向位移；藉此，当一螺件109结合在夹持槽102内，该螺件109的第一端面109a与第二端面109b抵靠着夹持槽102的第一、二夹持面104、105，而第三端面109c则受调整块106旋转而位移的活动块108所抵靠，而使该扳手100可作顺向或是逆向的单向扳动；然而在扳动过程中，扳手100可能受扳动环境的限制，而无法作过大的角度旋摆，(亦即无法作一相对螺件109的空转动作)，因此该扳手100的夹持槽102势必要离开螺件109，而将扳手100拿起，而回到可扳动的位置，并再次地将夹持槽102结合于螺件109，才能继续维持同一方向的扳动，此一方法使得扳动螺件的时间变长，造成操作上的不便，因此该扳手100有加以改良的必要。And as shown in Figure 1, it is the wrench structure diagram of U.S. Patent No. 5,415,064, which shows that awrench 100 has aclamping portion 101, and theclamping portion 101 has aclamping groove 102 and anadjustment groove 103, theclamping groove 102 has first andsecond clamping surfaces 104, 105; anadjustment block 106 is accommodated in theadjustment groove 103, and is pierced by anadjustment screw 107, and one end of theadjustment screw 107 extends into theclamping groove 102; amovable block 108 is Located in theclamping groove 102, and screwed with the end of the adjustingscrew 107, and by rotating the adjustingblock 106, themovable block 108 is axially displaced along the adjustingscrew 107; thereby, when ascrew 109 is combined in theclamping groove 102, the first end surface 109a and thesecond end surface 109b of thescrew 109 abut against the first andsecond clamping surfaces 104, 105 of theclamping groove 102, while thethird end surface 109c is displaced by the rotation of theadjustment block 106 Themovable block 108 abuts against, so that thewrench 100 can be pulled forward or backward in one direction; however, during the pulling process, thewrench 100 may be limited by the pulling environment and cannot be rotated at an excessive angle. pendulum, (that is to say, it is impossible to do a idling action relative to the screw 109), so theclamping groove 102 of thewrench 100 must leave thescrew 109, and thewrench 100 is picked up, and returns to the position where it can be pulled, and Only by combining theclamping groove 102 with thescrew 109 again can the wrench in the same direction continue to be maintained. This method makes the time for turning the screw longer and causes inconvenience in operation. Therefore, it is necessary to improve thewrench 100 .

而如图2所示，为美国专利第2,376,764号的图3所示的扳手结构图，其显示一扳手200具有一夹持部201，夹持部201具有一夹持槽202及一调整槽203，该夹持槽202内缘壁具有一齿状的夹持面204；一调整块205容纳在调整槽203，并受一调整螺杆206穿伸，而该调整螺杆206一端伸入夹持槽202；一活动块207是位于夹持槽202内，并与夹持面204对应设有一齿状夹持面208，而该活动块207与调整螺杆206螺合，而藉旋转调整块205，使活动块207顺着调整螺杆206轴向位移；藉此，当螺件结合在夹持槽202内，螺件的端面为夹持面204、208受抵靠，而使该扳手200可作顺向或是逆向的单向扳动，该扳手200的齿状夹持面204、208为一固定状，故该扳手200如同前述结构一样，在扳动过程中无法往复操作，亦无法相对螺件作空转动作，而造成操作不便，也具有加以改良的必要。And as shown in FIG. 2 , it is the wrench structure diagram shown in FIG. 3 of U.S. Patent No. 2,376,764, which shows that awrench 200 has aclamping portion 201, and theclamping portion 201 has aclamping groove 202 and anadjustment groove 203 , the inner wall of theclamping groove 202 has atoothed clamping surface 204; an adjustingblock 205 is accommodated in the adjustinggroove 203, and is stretched by an adjustingscrew 206, and one end of the adjustingscrew 206 extends into the clamping groove 202 Amovable block 207 is located in theclamping groove 202, and is provided with atoothed clamping surface 208 corresponding to theclamping surface 204, and themovable block 207 is screwed with the adjustingscrew rod 206, and by rotating the adjustingblock 205, the movable Theblock 207 is axially displaced along theadjustment screw rod 206; thereby, when the screw is combined in theclamping groove 202, the end faces of the screw are pressed against theclamping surfaces 204, 208, so that thewrench 200 can be used as a forward or It is a reverse one-way pulling. The tooth-shaped clamping surfaces 204, 208 of thewrench 200 are fixed, so thewrench 200, like the aforementioned structure, cannot be reciprocated during the pulling process, nor can it be idling relative to the screw. action, which causes inconvenience in operation, and it is also necessary to improve it.

Pulling the state diagram, however, this embodiment is based on the above-mentioned creation principle, and the clampingmember 43 is set at thefirst end 131 of the clampinggroove 13, wherein themovable block 30 has V-shaped first and second clamping surfaces 35, 36, and the outer periphery of the clampingpart 12 is provided with taperedfirst side wall 121 andsecond side wall 122, and thefirst side wall 121 is provided with an oblique step throughhole 123 to communicate with the clampinggroove 13, and Theperforation 123 has astopper 123a, so that the same clampingmember 43 as the above-mentioned embodiment is put into theperforation 123, and is supported by thespring 41, so that theconvex part 432 is against thestopper 123a; and adjusted by turning Theblock 21 displaces themovable block 30, and makes the first and second clamping surfaces 35, 36 of themovable block 30 abut against the first and second end surfaces 501, 502 of thescrew 50, and pushes thescrew 50 down, and Make its third and fourth end surfaces 503, 504 abut against theteeth 431 of the clampingmember 43, and be clamped by the clampingmember 43. Thesame wrench body 10 takes thescrew 50 as the center of rotation, and the screw can be 50 Turn clockwise;

而如图8所示，为显示夹持构件43被设置在夹持槽13第一端131上，且扳手本体10位于逆时针方向扳动的空转状态图，其藉扳手本体10以螺件50为旋转中心逆时针方向扳转时，且夹持构件43于穿孔123内缩退位，并压抵弹簧41，而能使扳手本体10形成空转状态，使其夹持构件43装设在夹持槽13内缘端壁上亦能具有往复操作的扳动效果。And as shown in FIG. 8 , in order to show that the clampingmember 43 is arranged on thefirst end 131 of the clampinggroove 13 , and thewrench body 10 is located in the idling state diagram when thewrench body 10 is pulled in the counterclockwise direction, it uses thewrench body 10 with thescrew 50 When the center of rotation is turned counterclockwise, the clampingmember 43 retracts in the throughhole 123 and presses against thespring 41, so that thewrench body 10 can form an idle state, so that the clampingmember 43 is installed in the clampinggroove 13 The inner edge end wall can also have the pulling effect of reciprocating operation.
