Description
Technical field
The utility model relates to the hand-operated tools technical field, especially a kind ofly is used to rotate the monkey wrench of tightening or unclamping nut, bolt.
Background technology
Its structure of monkey wrench that tradition is used is for including handle portion and spanner portion, this spanner portion one side is provided with a fixed jaw, a side relative with this fixed jaw is equipped with a movable clip block, movable clip block is connected with worm screw, in the time will regulating spanner portion opening big or small, thereby be to make the movable clip block move left and right realize regulating the size of opening by the hand-screw worm screw, and often be to have some setbacks owing to the angle inaccuracy of regulating packs into, catching phenomenon is arranged, and the speed of Tiao Jieing is slow like this, simultaneously after hours, need spanner is withdrawed from bolt, again the spanner inserting bolt is carried out work behind the revolution certain angle, inefficiency uses inconvenient.
Summary of the invention
The purpose of this utility model just provides a kind ofly can finish the work of tightening or unclamping nut, bolt continuously, high efficiency, monkey wrench easy to use.
To achieve these goals, the technical scheme that the utility model adopted is: comprise handle portion and spanner portion, this spanner portion one side is provided with a fixed jaw, a side relative with this fixed jaw is equipped with a movable clip block, described movable clip block is hinged by hinge axis and described spanner portion, described handle portion and one handle are hinged, and this handle is provided with a push rod towards a side of described movable clip block, and this push rod reaches the behind of described movable clip block clamping face.
In the technique scheme, described movable clip block can be contained in the groove of another fixed jaw of described spanner portion, described movable clip block also can have groove in it, and this groove is enclosed within outside the described spanner portion, and movable clip block can swing up and down around the pin joint that is hinged with spanner portion; Handle portion can be contained in the described handle, and this handle portion can do swinging of certain distance around the pin joint that is hinged with handle; Between above-mentioned handle portion and the described handle spring can be housed.
Owing to adopted technique scheme, the utility model compared with prior art, the beneficial effect that has is to finish the work of tightening or unclamping workpiece, high efficiency, easy to use continuously.

The specific embodiment
Below in conjunction with the accompanying drawing example, the utility model is described in further detail.
As Fig. 1, Fig. 2, embodiment 1 shown in Figure 3, the utility model includes 1-1 of handle portion and the 1-2 of spanner portion, this spanner portion right side is provided with fixed jaw 1-3, the left side also is provided with fixed jaw 1-4, be provided with groove 6 in the fixed jaw 1-4, movable clip block 2 is housed in this groove, this movable clip block is hinged with the 1-2 of spanner portion by screw 8, movable clip block 2 is done in fixed jaw 1-4 around screw 8 and is swung up and down, and has slotted hole 4 in the handle 3, and the 1-1 of handle portion is contained in this slotted hole, and it is hinged by rivet 5 and handle 3, this handle portion does swinging of certain distance around this rivet 5 in this slotted hole, handle 3 is provided with push rod 7, and this push rod reaches the behind of movable clip block 2 clamping faces, in order to promote movable clip block, make its clamping work pieces, be provided with spring leaf 9 between 1-1 of handle portion and the handle 3, this spring leaf is connected with the 1-1 of handle portion by screw 10.
As shown in Figure 4, during work, come clamping nut 11 by fixed jaw 1-3 and movable clip block 2, the active force of movable clip block 2 is to transmit, act on its back by handle 3.In clamping the course of work, active force passes to push rod 7 by handle 3, the back that push rod 7 promotes movable clip block 2, like this, external force is big more, and the active force that acts on the movable clip block back is just big more, movable clip block is near to fixed jaw 1-3 direction pendulum, the clamping force of nut 11 is also big more so, and binding nut is just firm more, thereby arrives the purpose of fastening nut; As shown in Figure 5, in unclamping the course of work, (annotate: be meant the work of unclamping that continues fastening nut and need the adjusting nut working face), because the change of external force direction, the active force that acted on the movable clip block back originally reduces gradually, and movable clip block just is in relative free movement state.When spanner rotates (generally being 60 ° of rotations), the working face of nut can be adjusted, so just can proceed to tighten or unclamped work.Owing to be provided with spring 9 between 1-1 of handle portion and the handle 3, can be when regulating working face, automatically judge whether to have resetted to regulate and finish: promptly when carrying out the adjusting nut working face, spring 9 is owing to be subjected to the pressure generation strain of handle, and handle rotates, and the active force that acts on the movable clip block back diminishes, meanwhile, movable clip block is positive, and movable clip block opens owing to be subjected to the extruding of nut corner angle, and nut 11 just can climb over its corner angle.After climbing over corner angle, movable clip block automatically resets clamping work pieces under the suffered active force that comes from the spring force on the handle in its back.Reset finish after, spring force disappears, handle and handle portion are in parastate, tighten or the work of unclamping is finished.So repeatedly, promptly tighten back and forth serially or unclamp nut.
As Fig. 6, Fig. 7, among the embodiment 2 shown in Figure 8, the utility model includes 101-1 of handle portion and the 101-2 of spanner portion, this spanner portion right side is provided with fixed jaw 101-3, the left side of this spanner portion is provided with movable clip block 102, have groove 106 in this movable clip block, this groove is enclosed within outside the fixed jaw 101-4, movable clip block 102 is hinged with the 101-2 of spanner portion by screw 108, movable clip block 102 is done outside fixed jaw 1-4 around screw 108 and is swung up and down, have slotted hole 104 in the handle 103, the 101-1 of handle portion is contained in this slotted hole, and it is hinged by rivet 105 and handle 103, this handle portion this rivet 105 of having mercy on is done swinging of certain distance in this slotted hole, handle 103 is provided with push rod 107, and this push rod reaches the behind of movable clip block 102 clamping faces, in order to promote movable clip block, make its clamping work pieces, be provided with spring leaf 109 between handle portion 101 and the handle 103, this spring leaf is connected with the 101-1 of handle portion by screw 1010.
Working method is identical with embodiment 1.
