Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention.

Drawings

Fig. 1 is a front view of the present invention.

Fig. 2 is a front view of the present invention (with the wear-resistant layer removed).

In the figure: the novel anti-abrasion wear-resistant sleeve comprises a shell body 1, a containing cavity 11, a holding part 12, a base layer 121, a groove 1211, a convex strip 1212, a wear-resistant layer 122 and a screw hole 123.

Detailed Description

The following detailed description of the present invention will be made with reference to the accompanying drawings and examples.

As shown in fig. 1-2, the utility model provides a technical solution: wear-resisting plastics handle of antiskid, including housing body 1, the inside holding chamber 11 that is equipped with in housing body 1 upside position, and housing body 1 downside is gripping portion 12, and gripping portion 12 is bilayer structure, is located inside basic unit 121 and is located outside wearing layer 122 respectively, and the surface of basic unit 121 is equipped with interval crisscross sand grip 1212 and recess 1211, and wearing layer 122 laminates on basic unit 121.
