Composite sleeve

Abstract

The invention discloses a composite sleeve. The composite sleeve is characterized in that a driving hole is formed in sleeve body, the sleeve body can be divided into a first sleeve section, a secondsleeve section and a third sleeve section, a first step portion is formed between the first sleeve section and the second sleeve section, a second step portion is formed between the second sleeve section and the third sleeve section, a stress ring piece sleeves the outer side of the first sleeve section of the sleeve body and abuts against the first step portion, a protective sleeve is assembled on the sleeve body in a sleeving mode, is attached to the outer wall surface of the second sleeve section and abuts against the second step portion, a gap is formed between the protective sleeve and the outer wall surface of the first sleeve section, the stress ring piece is located in the gap, and an identification hole is formed in the protective sleeve in a hollow mode. Due to hollow arrangementof the identification hole, the oil stain can be accommodated in the identification hole, in addition, due to the design of the thickness of the protective sleeve, the integrity of the sleeve body inoperation can be completely protected through installation of the protective sleeve, and the continuous use can also can be achieved without separating of the protective sleeve.

Description

technical field [0001] The invention is a composite sleeve, which refers to the technology applied in the field of hand tools in detail. The main technology is to provide reliable pivoting, remove the screws, bolts, and nuts applied to the wheel rim of the car, and in the process of operation It will not damage the sleeve and the rim, so as to protect the usability of the sleeve and the rim, which is highly progressive and practical. Background technique [0002] The socket is a very practical part of hand tools, which can be combined with a wrench to provide users with access to and lock screws, nuts, bolts and other parts, especially those in the automotive field who need to use it. Another function of the sleeve is to provide users with deep locking screws, nuts, and bolts. The sleeve can be inserted into the holes in the rim corresponding to the locking positions of the screws, nuts, and bolts for operation. smooth, so there will be more or less oil stains attached to t...

AI Technical Summary

Problems solved by technology

[0009] In order to improve the prior art listed above, because the transparent bushing becomes unrecognizable after being stained with oil, and the screw cannot be inserted smoothly due to the small diameter of the rim lock hole in use. , Bolts, nuts assembly and disassembly are lacking, the present invention provides a composite sleeve, the user can more clearly identify the size of the sleeve to be taken, and the identification will not be delayed due to the influence of oil pollution, and more The important thing is that under the protection of the rim and sleeve body, it can be inserted into the lock hole for disassembly and assembly of screws, bolts, and nuts without being affected by the size of the lock hole.
