Connecting method of cue

Abstract

The invention discloses a connecting method of a cue. According to the connecting method of the cue, a connecting rod (1), an inner cylinder (2) and an outer cylinder (3) are used, wherein the connecting rod (1) is connected to the tail end of a front cue branch and is a cylinder with a smooth surface, the connecting rod (1) is provided with no threads, a rear cue branch is formed by the inner cylinder (2) and the outer cylinder (3), the inner cylinder (2) and the outer cylinder (3) are connected through threads, the outer diameter of the front section of the inner cylinder (2) is identical with that of the outer cylinder (3), the inner diameter (2) of the inner cylinder (2) is identical with the outer diameter of the connecting rod (1), the outer diameter of the rear end of the inner cylinder (2) is identical with the inner diameter of the outer cylinder (3), two or more hollow grooves are formed at positions, close to the front section, of the rear end of the inner cylinder (2), the lower end of each hollow groove is connected with an elastic piece (4), the elastic pieces (4) tilt outwards under the condition that the elastic pieces (4) are not squeezed by external force, the elastic pieces (4) are withdrawn towards the hollow grooves when the elastic pieces (4) are pushed upwards in a rotary mode through threads together with the outer cylinder (3) and come close to the front end of the inner cylinder (3), and then the connecting rod (1) stretching into the inner cylinder (2) is clamped. The connecting method of the cue has the advantages that the length of the cue can be adjusted directly, and connection of the cue is firm.

Description

technical field [0001] The invention relates to billiard sports equipment, in particular to a connection method of a billiard cue. technical background [0002] In billiards, because everyone's height is different, the requirements for the length of the club are different. Someone once proposed a technical solution, which is to connect a threaded connecting rod behind the front branch, and connect it with the rear branch through threads. , put some rings on the connecting rod to increase or decrease the length, but its problem is that the total weight is also passively changed when the length is adjusted, the length cannot be simply adjusted, and more importantly, the thread structure on the connecting rod It is complicated, so that the connecting rod and the front branch cannot be connected into one piece and formed at one time, which makes it difficult to ensure the coaxiality of the front branch and the connecting rod during processing.
