Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 to 3, a sleeve for a self-drilling screw includes a sleeve 100 and a handle 200 connected to the sleeve 100, the sleeve 100 includes an inner sleeve 110 and an outer sleeve 120, an octagonal hole 130 is formed in the inner sleeve 110, a magnetic member 140 is disposed in the octagonal hole 130, the magnetic member 140 is a magnet, an inner wall of the octagonal hole 130 directly contacts with an outer surface of the magnetic member 140, so as to increase a contact area with the magnetic member 140, and make it more firm, and when the sleeve works, the magnetic member 140 can absorb a nut of the self-drilling screw, thereby preventing a slip and reducing a wear frequency of the nut.
