Problems solved by technology

[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.

Abstract

The invention discloses a scaling type universal socket spanner applicable to common external hexagonal screws. The socket spanner comprises a socket mandrel. The upper end of the mandrel is providedwith a thread, and six evenly-distributed grooves are formed in the lower end of the mandrel. Six sliding blocks capable of moving in the radial direction are evenly distributed in the circumferentialdirection and matched with the grooves. The lower portion of each sliding block has a taper. A hole is formed in the inner side of each sliding block. A hexagonal mandrel is assembled in the middle of the mandrel through a screw, and the lower portion of the mandrel is provided with six evenly-distributed holes which correspond to the holes in the sliding blocks. Compression springs are installedin the opposite holes of the sliding blocks and the hexagonal mandrel. A shell with knurling is arranged outside a whole socket. The inner side of the lower end of the shell is matched with the taperfaces of the sliding blocks. The shell can move up and down along the mandrel in an internal threaded fit mode, and through vertical movement of the shell, radial scaling of the sliding blocks is achieved so that the socket spanner can adapt to external hexagonal screws with 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...
