Embodiment Construction

[0011] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0012] see figure 1 , a cam structure live mouth wrench, including a cam 5, a cross bar 9 is fixed on the side of the cam 5, and the cross bar 9 is used as a handle, which adopts a steel structure, and is wrapped with a layer of rubber on the outside, which does not rub hands, and can conveniently control the movement of the cam 5 .

[0013] The middle of the cam 5 is provided with a rotating shaft 8 that runs through it so that the cam 5 can rotate around it. The upper surface of the cam 5 is provided with an arc-shaped groove 4, and a track 3 is arranged in the arc-shaped groove 4. The track 3 is connected to the living port. Pull lip 1 bottom roller 2 slide connection, and roller 2 is connected with movable mouth pull lip 1 by rotating shaft, and movable mouth pull lip 1 is arranged on an end in track frame 7, and the other end in track frame 7 is fixed w...

Abstract

The invention provides a shifting wrench of a cam structure. The shifting wrench comprises a cam, and the middle of the cam is provided with a rotating shaft which penetrates through the cam. The upper surface of the cam is provided with an arc slot, the arc slot is internally provided with a rail, the rail is slidably connected with an idler wheel connected to the lower portion of a shifting wrench lip, and the idler wheel is connected with the shifting wrench lip through a revolving shaft. The shifting wrench lip is arranged at one end in a track box, and the other end in the track box is fixedly provided with a stay wrench lip. The cam rotates around the rotating shaft by pulling a transverse rod, therefore the shifting wrench lip moves in the track box, the distance between the shifting wrench lip and the stay wrench lip is changed, thus various bolts of different specifications are fastened or detached, and the shifting wrench has the characteristics of being convenient to use, flexible, economical and practical.

Description

technical field [0001] The invention relates to a cam structure adjustable wrench. Background technique [0002] At present, the wrenches on the market are mainly used for unscrewing hexagonal screws. The existing wrenches are generally composed of a wrench handle and an adjustable wrench head. The opening size of the adjustable wrench can be adjusted within a certain range, so it can be used For the fastening or dismounting of bolts of various specifications. The adjustment of the general adjustable wrench is to use the turbine and the shaft pin to control the distance between the movable wrench lip and the dead wrench lip. This adjustment method is more laborious after a long time. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned prior art, the object of the present invention is to provide a cam structure live wrench, which can save effort and conveniently adjust the distance between the live wrench lip and the dead wrench ...
