Self-adaption sleeve and spanner

Abstract

The invention provides a self-adaption sleeve and a spanner and relates to the field of production tools. The self-adaption sleeve comprises a central shaft, a shaft sleeve body and abutting components. A fixing hole is formed in the shaft sleeve body; sliding grooves are formed in the side wall of the fixing hole in the circumferential direction; the central shaft is arranged in the fixing hole;a mounting hole is formed in the central shaft in the axis direction; positioning holes are formed in the central shaft in the radial direction of the mounting hole and communicate with the mounting hole; the abutting components are arranged in the positioning holes correspondingly, one ends of the abutting components abut against the interiors of the sliding grooves correspondingly, and the otherends of the abutting components are used for abutting against a fastener; the abutting components slide in the corresponding sliding grooves so as to change the lengths of the portions, stretching into the mounting hole, of the abutting components, and accordingly, the abutting components can abut against fasteners of different specifications. The self-adaption sleeve can be used for production operation of bolts or nuts of different specifications and models, the production efficiency is improved, and the application cost is also lowered.

Description

technical field [0001] The invention relates to the field of production tools, in particular to an adaptive sleeve and a wrench. Background technique [0002] At present, traditional bolts and nuts are generally installed using a special wrench or a special specification sleeve. However, most wrenches can only be matched with bolts and nuts of one specification, and cannot be used universally. [0003] When in use, wrenches of corresponding specifications must be replaced for bolts and nuts of different specifications, which reduces work efficiency, and in normal production and life, wrenches or sockets of different specifications are required at the same time, which is inconvenient to carry, troublesome to organize, and increases It reduces the cost and brings a lot of inconvenience to our actual life and production. [0004] Therefore, designing a socket or wrench that is applicable to different types and specifications is an urgent problem to be solved at present. Con...
