Self-centering sleeve head

Abstract

A self-centering sleeve head comprises a sleeve body. A radial slide groove is formed in the sleeve body. A left clamping block and a right clamping block are arranged in the slide groove and can slide leftwards and rightwards along the slide groove. A two-way threaded rod is connected between the left clamping block and the right clamping block. The left clamping block and the right clamping block are connected with the two-way threaded rod through threads. Fixing sleeves are arranged at the two ends of the two-way threaded rod. The fixing sleeves and the two-way threaded rod are fixedly connected through limiting pins. The self-centering sleeve head can be suitable for detaching and installing bolts of various different specifications and sizes and nuts of various different specifications and sizes and can replace an existing sleeve head. The manufacturing cost of a sleeve spanner is reduced, and the self-centering sleeve head is convenient to carry.

Description

technical field [0001] The invention relates to the technical field of mechanical tools, in particular to a self-centering sleeve suitable for dismounting bolts and nuts of various specifications. Background technique [0002] The socket wrench is a tool often used in mechanical installation or disassembly. The socket wrench not only has a large torque and a small rotation diameter, but also can increase the working torque during installation or disassembly by lengthening the torsion bar. Therefore, in various production practices be widely used. However, socket wrenches often need to be equipped with various socket heads of different specifications, and a socket can only be matched with a nut of one size specification (buying a set of M6-M20 socket wrenches on the market often needs to be equipped with 7-9 socket head), and the existing socket head is often helpless for some special specifications of hexagonal nuts and square nut heads, because the socket head is a fixed s...

However, socket wrenches often need to be equipped with various socket heads of different specifications, and a socket can only be matched with a nut of one size specification (buying a set of M6-M20 socket wrenches on the market often needs to be equipped with 7-9 socket head), and the existing socket head is often helpless for some special specifications of hexagonal nuts and square nut heads, because the socket head is a fixed size, and at the same time, the increase in the socket head will inevitably lead to the inconvenience of carrying the whole set of tools. , high manufacturing costs and other issues
