Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: a double-end fastening type copper sleeve for a computer fan comprises a connecting pipe 1, a head pipe 2, a first groove 3, a second groove 4, a semicircular groove 5, a reinforcing ring 6, a first threaded hole 7, a second threaded hole 8, a threaded rod 9, a rotating rod 10, a limiting hole 11, a spring 12, a marble 13, an anti-skid pattern 14 and a knurled pattern 15, wherein the head pipe 2 is fixedly connected to the upper end and the lower end of the connecting pipe 1, the first groove 3 and the second groove 4 are sequentially formed in the head pipe 2 from top to bottom, the semicircular grooves 5 which are symmetrically arranged are formed in the outer side of the second groove 4, and the reinforcing ring 6 is fixedly connected to the outer side of the connecting pipe 1;
