Abstract

The invention discloses a universal socket wrench applied to ordinary hexagonal sockets. The socket wrench includes a socket mandrel. The upper end of the mandrel is threaded, and the lower end is provided with six evenly distributed grooves. Six radially movable sliders are evenly distributed on the circumference of the grooves. Taper, there is a hole on the inner side of each slider, a hexagonal mandrel is assembled with a screw in the middle of the mandrel, and there are six evenly distributed holes on the lower part of the mandrel corresponding to the holes on the slider, between the slider and A compression spring is installed in the opposite hole of the hexagonal mandrel. The outside of the whole sleeve is a shell with knurling. The inside of the lower end of the shell is matched with the tapered surface of the slider. The inside of the shell can move up and down along the mandrel through thread fit. , the radial scaling of the slider is achieved by moving the housing up and down to accommodate hexagonal screws of different diameters.

Description

technical field [0001] The invention belongs to the technical field of operation tooling, and relates to a zoom-type universal socket wrench. Background technique [0002] At present, special hexagonal wrenches are generally used for the installation of outer hexagonal fasteners, but most of the hexagonal wrenches can only be adapted to one specification of hexagonal screws, especially now with the increasing pace of internationalization, the ones we use around us Many products are imported. When there are imperial fasteners, our metric wrenches are basically helpless, which brings a lot of inconvenience to our actual life and production. Contents of the invention [0003] (1) Purpose of the invention [0004] The purpose of the present invention is to provide a zoom-type universal socket wrench to meet the needs of screws with different diameters. [0005] (2) Technical solution [0006] In order to solve the above technical problems, the present invention provides a z...
