Abstract
The present invention relates to a socket used in coordination with a wrench. The socket includes a socket main body which has a head portion and a body portion connected to the head portion. The head portion is adapted for being coupled with the wrench. The body portion has a polygonal hole for being coupled with a head portion of a bolt or a nut, so that the wrench is adapted for screwing on or off the bolt or nut through the socket main body. Besides, a pipe made of composite material is sleeved onto the external peripheral surface of the body portion. The pipe is freely detachable, and the external peripheral surface of the pipe can be provided with a print, pattern, color or character according to the practical demands, thereby attaining the effects of high variability in appearance, great durability and great recognizability.
