Blocking 15 and blocking 16 are arranged respectively at the two ends of rotating shaft 12, and blocking 15 and blocking 16 are clamped on the both sides of second axle sleeve 11, are used to limit rotating shaft 12, make rotating shaft 12 not be able to come from both sides. come out. A sleeve 13 is fixed in the middle of the rotating shaft 12 , the cross sections of the rotating shaft 12 and the sleeve 13 are hexagonal, and the rotation of the rotating shaft 12 drives the sleeve 13 to rotate. A spring 14 is sleeved on one end of the rotating shaft 12, and one end of the spring 14 is stuck on the plug 15 of this end, and the other end is stuck on the end of the sleeve 13, and the sleeve 13 can compress the spring 14 when the rotating shaft 12 moves. It is also possible not to adopt the structure of fixing the sleeve 13 on the rotating shaft 12, but only have structures such as protrusions on the rotating shaft 12, and the springs 14 are compressed by the protrusions. An operable screw 17 is arranged outside the blockage 16 at the other end of the rotating shaft 12, and an internal thread hole 18 is arranged at the center of one end of the rotating shaft 12. The operable screw 17 and the rotating shaft 12 are fixedly connected by threads, and the operator presses the screw 17. The sleeve 13 compresses the spring 14. After letting go, the spring 14 resets, and the rotating shaft 12 also resets thereupon. The operator turns the screw 17 to drive the rotating shaft 12 to rotate.
