Easy-to-use connection sleeve

Abstract

The invention discloses an easy-to-use connection sleeve, and relates to the technical field of sleeves. The easy-to-use connection sleeve comprises a sleeve wrench, a wrench fixing rod, a telescopingrotation cylinder, a telescoping rotation rod and a sleeve connecting cylinder which are arranged from bottom to top in sequence. A sleeve connector which is fixedly welded to the lower surface of the wrench fixing rod is sleeved with the sleeve wrench, the lower end of the telescoping rotation rod is movably sleeved with an inner cavity of the telescoping rotation sleeve, the telescoping rotation rod is of a hexagonal prism structure, the shape of the inner cavity in the telescoping rotation cylinder is matched with that of the telescoping rotation rod, and the lower end of the telescoping rotation rod and the upper end of the telescoping rotation cylinder are fixed with a pin. By means of the easy-to-use connection sleeve, the aim that the connection sleeve for removing a nut or a boltis changed into a vertical form or an L-shaped form is achieved, and the shape of the connection sleeve can be changed according to actual demands in use; when the connection sleeve is in an L shape,the torque can be changed, and when the nut or the bolt is removed, labor is saved.

Description

technical field [0001] The invention relates to the technical field of sleeves, in particular to an easy-to-use adapter sleeve. Background technique [0002] Socket is the abbreviation of socket wrench, which is suitable for bolts or nuts. There are many types of socket wrenches in practice. Different types of socket wrenches can be replaced with different adapter sockets for correct use. [0003] Chinese patent publication No. CN 105003763 B discloses a safety adapter, which is configured to connect first and second fluid pipeline sections of a fluid pipeline. The safety adapter according to the invention has an inner sleeve which has a fastening thread on the end region of the first sleeve for connection to the first fluid line section and on the second sleeve An external thread configured as a drive thread is provided on the end region. The external thread can be screwed tightly with the internal thread of the outer sleeve, wherein a stopper is provided on the inner cir...

AI Technical Summary

Problems solved by technology

[0006] 1. The sleeve in the device is a straight-rod adapter sleeve, which cannot be changed according to actual needs;

[0007] 2. The existing socket wrenches often have L-shaped rod type, both of which are not interchangeable, and can only be used in specific places. It is often necessary to prepare two or more sets of socket wrench tools before they can be supplied. In most cases, it is a waste of cost, and it is a waste of space to prepare a large number of different types of socket wrenches
