Problems solved by technology

The most common one is the screw-type adjustable wrench. The screw-type adjustable wrench uses a screw to adjust the opening size, which can continuously change the opening size, but the adjustment speed is very slow and needs to be adjusted many times; When in use, there are often nuts of different sizes, which require a wrench of the corresponding size to adjust. The use process is cumbersome and affects work efficiency.

Abstract

The invention discloses an opening size adjustable spanner and relates to the spanner. The opening size adjustable spanner comprises a handle portion, wherein one end of the handle portion is provided with a head portion; the head portion comprises a ring; six first through holes are uniformly formed in the inner side wall of the ring in the periphery direction; each first through hole is internally provided with a cylinder; one end of each cylinder is provided with a baffle board; second through holes are symmetrically formed in the two ends of each baffle board; a steel rope penetrates through the second through holes in the six baffle boards. Compared with the prior art, the opening size of the opening size adjustable spanner can be adjusted according to the actual requirements, the requirements of production and machining are met, the structure is reasonable, the operation is convenient, the working efficiency is greatly improved, and the industrial production is achieved.

Description

technical field [0001] The invention relates to a wrench, in particular to a wrench with adjustable opening size. Background technique [0002] At present, tools such as adjustable wrenches and dead end wrenches are commonly used when tightening nuts. The most common one is the screw-type adjustable wrench. The screw-type adjustable wrench uses a screw to adjust the opening size, which can continuously change the opening size, but the adjustment speed is very slow and needs to be adjusted many times; When in use, there are often nuts of different sizes, which need to be adjusted with wrenches of corresponding sizes. The use process is cumbersome and affects work efficiency. The above problems need to be solved urgently. Contents of the invention [0003] The invention aims at the deficiencies in the prior art and provides a wrench which can adjust the size of the opening. [0004] In order to solve the above technical problems, the present invention is solved by the fol...
