Description

Internal and external dual-purpose sleeve

Technical Field

The invention relates to the technical field of mounting and dismounting tools, in particular to an internal and external dual-purpose sleeve.

Background

A large number of convex or concave fasteners such as nuts, inner angle bolts, inner angle pins and the like are applied to engineering equipment, the variety is various, the specification is various, and irregular structures are sometimes even used. When a fastener with a regular shape is disassembled and assembled, a socket or a wrench with a fixed shape and size is generally used, but the used tool needs to have the same specification as the disassembled or assembled fastener, and for mechanical equipment using fasteners with various specifications, an operator needs to frequently replace the tool, so that the working efficiency is extremely low. While a spanner wrench may be used, frequent adjustment of the wrench opening is still required and conventional tools are often not suitable for machines with both male and female fasteners. In addition, when the irregular fastener is disassembled and installed, the field exertion of operators is often needed, the use requirements are met by combining various tools, the standard operation is avoided, and the working efficiency and the installation effect cannot be ensured.

In the prior art, a universal sleeve is arranged through a series of spring columns arranged in a honeycomb manner when irregular fasteners are disassembled and assembled, but the design is only suitable for fasteners with convex working contact shapes, and cannot be used for concave fasteners, so that the 'universal' in the true sense cannot be realized. In order to solve the problems in the prior art, the invention provides a fastener which is not only suitable for a male fastener, but also suitable for a female fastener.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Examples

As shown in fig. 1-2, the invention discloses an internal and external dual-purpose sleeve, which comprises a sleeve 1, a fixing plate 2 and a clamping column 3, wherein a quadrilateral groove 11 is formed on one side end surface of the sleeve 1, a containing cavity 12 is formed on one end of the sleeve 1 far away from the groove 11, the fixing plate 2 is arranged in the containing cavity 12 and is positioned at one end of the containing cavity 12 close to the groove 11, first through holes 21 are uniformly formed on the fixing plate 2, the clamping column 3 passes through the first through holes 21 to be connected with the fixing plate 2 in a sliding manner, a first bump 31 and a second bump 32 are fixedly connected on the side wall of the clamping column 3, the first bump 31 is contacted with one side end surface of the fixing plate 2 close to the groove 11, a return spring 33 is sleeved on the clamping column 3, one end of the return spring 33 is contacted with, the other end of the second protrusion contacts with the end face of the second protrusion 32, and the end of the clip column 3 far away from the first protrusion 31 protrudes out of the end face of the sleeve 1. Joint post 3 outstanding in sleeve 1's terminal surface, not only can install and dismantle the fastener of external convex type, can also install and dismantle the fastener of internal concave type, when the fastener of external convex type is installed and is dismantled, the joint post 3 that corresponds with the fastener bulge is impressed and is held in chamber 12, install and dismantle the fastener in the joint post 3 of 1 terminal surface of sleeve, when installing and dismantling the fastener of internal concave type, the joint post 3 that corresponds with the internal concave part of fastener stretches into in the inner cavity of fastener, thereby the joint is lived the fastener and is installed and dismantle the fastener, realize universal sleeve 1 in the true sense, thereby guarantee work efficiency and installation effectiveness.

Hold and be provided with the top cap 4 parallel with fixed plate 2 in the chamber 12, set up the second through-hole 41 that supplies joint post 3 to pass on the top cap 4, joint post 3 slides with top cap 4 and is connected.
