Abstract

The utility model discloses a novel monkey wrench which comprises a handle. A fixed clamping plate and a movable clamping plate are arranged on the end portion of the handle, the movable clamping plate is connected with a spring, a rack is arranged at the bottom of the movable clamping plate, a positioning pin and a lifting lever are arranged on the handle, a slider is arranged on the handle and connected with a connecting rod, one end of the connecting rod contacts with the positioning pin, a clamping pin is arranged on the connecting rod, the lifting lever is hinged on the handle, and one end of the lifting lever acts on the end portion of the rack while the other end of the same is controlled by the clamping pin. In the novel monkey wrench, the movable clamping plate is automatically meshed and locked with a nut, so that troubles caused by repeated adjusting are avoided, slipping can be avoided, and safety and convenience in use are realized.

Description

A kind of novel shfting wrench

Technical field

The utility model relates to a kind of hardware ﹠ tools, particularly a kind of spanner.

Background technology

Shfting wrench uses very extensive, when it dehisces size in change, need manual adjustments, the another one problem is that the positioning accuracy of portable plate is relatively poor, and portable plate in use can slightly be offset, consequently in use, " skidding " phenomenon may appear, need constantly finely tune its size of dehiscing, inefficiency, this also is the reason that a lot of workmans are unwilling to use shfting wrench.

The utility model content

The purpose of this utility model provides a kind of novel shfting wrench, can be automatically and the nut interlock, and overcome and regulate dehisce big or small complex operation and the low defective of precision in the prior art.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is:

Can be automatically and the shfting wrench of nut interlock, comprise handle, be provided with strap and ambulatory splint in handle end, ambulatory splint is connected with spring, and described ambulatory splint bottom is provided with tooth bar, is provided with alignment pin and driving lever at handle.

As preferably, can slide block be set at handle, slide block is connected with connecting rod, and an end of connecting rod contacts with alignment pin, and connecting rod is provided with bayonet lock.

Described driving lever is articulated on the handle, and driving lever one end acts on the tooth bar end, and the other end is controlled by bayonet lock.

Described alignment pin is articulated on the handle, and is provided with elastic component at alignment pin, be not subjected under the external force effect, and alignment pin keeps disengaged position with tooth bar under the effect of elastic component.

The beneficial effects of the utility model are: the turbine that is used for regulating ambulatory splint in the existing shfting wrench of the utility model cancellation, adopt driving lever can ambulatory splint be opened, ambulatory splint is under the effect of spring, and with the automatic interlock of nut, alignment pin is with live splint mortice lock tightening position.Avoided the trouble of regulating back and forth, the phenomenon that also can not occur skidding is simultaneously used safety, convenient.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the structural representation of second kind of state of the utility model;

Fig. 3 is the structural representation of the third state of the utility model;

Fig. 4 is the structural representation of the 4th kind of state of the utility model;

Among the figure: 1, ambulatory splint; 2, strap; 3, tooth bar; 4, driving lever; 5, handle;

6, slide block; 7, connecting rod; 8, bayonet lock; 9, alignment pin.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is elaborated.

As shown in Figure 1, a kind of can be automatically and the shfting wrench of nut interlock, comprise handle 5, be provided with strap 2 and ambulatory splint 1 in handle 5 ends, ambulatory splint 1 is connected with spring, ambulatory splint 1 bottom is provided with tooth bar 3, is provided with alignment pin 9 and driving lever 4 at handle 5.

As preferably, can slide block 6 be set at handle 5, slide block 6 is connected with connecting rod 7, and an end of connecting rod 7 contacts with alignment pin 9, and connecting rod 7 is provided with bayonet lock 8.Driving lever 4 is articulated on the handle 5, and driving lever 4 one ends act on tooth bar 3 ends, and the other end is controlled by bayonet lock 8.Alignment pin 9 is articulated on the handle 5, and is provided with elastic component at alignment pin 9, be not subjected under the external force effect, and alignment pin 9 keeps disengaged position with tooth bar 3 under the effect of elastic component.

Operation principle is as follows:

As shown in Figure 1, pull down movable slider 6, drivening rod 7 is downward, and alignment pin 9 is thrown off in connecting rod 7 ends, and alignment pin 9 is thrown off with the tooth bar of ambulatory splint, as shown in Figure 2 under the effect of elastic component.

Continue to pull down movable slider 6, it is downward to continue drivening rod 7, and the bayonet lock 8 on the connecting rod 7 drives driving lever 4 and rotates, and driving lever 4 other ends are stirred ambulatory splint 1 and opened, as shown in Figure 3.

Strap 2 and the ambulatory splint 1 of shfting wrench are snapped in the corresponding nut, decontrol slide block 6, ambulatory splint 1 is under the effect of spring, automatically and the nut interlock, after the interlock, promote slide block 6 forward, slide block 6 drivening rods 7, connecting rod 7 tops drive alignment pin 9 and rotate, be inserted in the tooth bar 3 of ambulatory splint 1, play the effect of positioning and locking, in use, the phenomenon of ambulatory splint skew can not occur.

More than disclosed be the specific embodiment of this patent only, but this patent is not limited thereto, for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model principle, the distortion of making should be considered as belonging to the utility model protection domain.
