The present invention provides a device for fixing a sports stick, in which friction between a taper member and a pressing member is minimized, so wear resistance is improved and assembling properties can be enhanced. The device for fixing a sports stick comprises an upper pipe, a lower pipe inserted in the upper pipe to be able to be withdrawn, and a fixing means for fixing the lower pipe and the upper pipe. The fixing means comprises: a stick body including a coupling unit having one side coupled with the inside of the lower pipe by means of a support member, and including a screw thread formed in a middle part of a cylindrical unit extended on the coupling unit; a taper member including a screw unit formed in the inner diameter thereof to be screwed and coupled with the screw thread unit of the stick body, and including a guide projection formed on the outer circumferential surface thereof on which a taper surface is formed; a pressing member coupled with the outer surface of the taper member, including a guide groove in which the guide projection ascends and descends, and including a compressing piece compressed on the upper pipe by means of the taper surface of the taper member; a desorption preventing member fixed on the upper surface of the stick body; and an elastic member interposed between the desorption preventing member and the pressing member. A plurality of closely placed projections protrudes on the upper side of the pressing member, and a slot having a reversed U shape is formed around the compressing piece. Also, a second elastic member which is stronger than the elastic member is further coupled with the lower side of the stick body. |
