Embodiment Construction

[0012] Such as figure 1 As shown, the wrench is provided with a long and flat handle 1, and one end of the handle 1 is provided with a fixed jaw 3 and a movable jaw 2, the fixed jaw 3 is connected with the handle 1, and the movable jaw 2 The activity is installed on the handle 1. One end of the movable jaw 2 is provided with a protrusion with a circular cross section, the thickness of the raised portion is greater than the thickness of other parts of the movable jaw 2, and the movable jaw 2 is provided with straight teeth at the raised portion. The handle 1 is provided with a groove corresponding to the shape of the cross section of the movable jaw 2 , and the cross section of the groove is the same as the shape of the cross section of the movable jaw 2 . The movable jaw 2 is embedded in the groove, so that the movable jaw 2 can only move along the groove, and the positional relationship between the movable jaw 2 and the fixed jaw 3 changes after sliding in the groove. Since...

Abstract

The invention discloses a wrench which comprises a handle, a fixed jaw and a movable jaw, wherein the fixed jaw is located at one end of the handle, the movable jaw is movably connected to the handle and opposite to the fixed jaw, a shifting rod is arranged on the handle, straight teeth are arranged on the shifting rod, straight teeth are arranged on the movable jaw, the movable jaw and the shifting rod are connected through a straight gear, and the straight gear is located inside the handle. According to the wrench, the position of the movable jaw can be adjusted by pushing the shifting rod, and then adjustment of the opening degree of the wrench is achieved. Shifting rod adjustment has the advantages of being high in practicality and convenient to use. By the adoption of the wrench, working efficiency can be greatly improved.

Description

technical field [0001] The invention relates to a wrench. Background technique [0002] The position of the movable jaw of the existing wrench is adjusted by the helical column arranged at one end of the handle, and such a wrench has the disadvantage of being inconvenient to use. During normal work, the helical column needs to be twisted to make the movable jaws installed on the handle move linearly, thereby adjusting the position of the movable jaws so that the distance between the fixed jaws and the movable jaws can be adapted to the work needs. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a wrench with convenient adjustment of movable jaws. [0004] In order to solve the above technical problems, the present invention adopts the following technical scheme: the wrench includes a handle, a fixed jaw and a movable jaw, the fixed jaw is located at one end of the handle, and the movable jaw is movably connected to the ...
