Abstract

The invention discloses a wrench used in a narrow space. The wrench comprises a large bevel gear, a small bevel gear, a gear rack, a rocker, a needle bearing, and the like. The rotation of the rockerdrives the rotation of the small bevel gear, and the small bevel gear drives the large bevel gear to rotate to tighten or loosen a bolt and a nut. When the wrench is in operation, all that is needed is to extend a front end, sleeves workpiece with the front end, and then shake the rocker to work, and the wrench does not need to swing left and right like an ordinary wrench, and is particularly suitable for working in the narrow space. The wrench is structure in simple and wide in application, and has great promotion value.

Description

technical field [0001] The invention relates to the technical field of hardware tools, in particular to a wrench.
