After the adjustment is completed, the worm 55 can limit the worm wheel 54, cooperate with the connecting rod 53, so that the gear 52 cooperates with the tooth block 51 to limit the outer rod 22, so that the outer rod 22 does not move. The overall structure is simple, the length of the bunker cue 2 can be adjusted, and it is suitable for use by different people, and it will not get loose during use, thereby improving practicality.
[0029] like Figure 4 As shown, the positioning unit 5 also includes a screw groove 56 opened at the outer end of the worm 55, and the screw groove 56 is a regular hexagonal structure; an inner hexagonal wrench is inserted into the screw groove 56 to rotate the worm 55.
