As shown in fig. 4, the sum of the radial lengths of the notch 15 and the sliding hole 14 of the notch wheel 9 is greater than or equal to the length of the limiting component, in the present invention, when the notch 15 corresponds to the sliding hole 14, the sum of the length of the notch 15 and the length of the sliding hole 14 is at least equal to the length of the limiting component, and generally, the sum needs to be greater than the length of the limiting component, so that the limiting component can completely exit from the crescent 6 only at one end of the limiting component facing the crescent 6 when the notch 15 is retracted, and the crescent 6 cannot block the limiting component, so that the rotation of the rotating cylinder 7 cannot be limited; in addition, the width of the notch 15 and the sliding hole 14 can ensure that the limiting component can freely slide, but the limiting component cannot be too large, the limiting component can be limited to slide in the relative position of the sliding hole 14 and the notch 15, and the dislocation is avoided. As shown in fig. 5, 7, 11 and 12, the present invention provides a solution for connecting the position limiting assembly, the sliding chute 40, the compression spring 42 and the sliding block 41, wherein one end of the compression spring 42 abuts against one end of the sliding chute 40 close to the center of the second circular cavity 13, the other end of the compression spring 42 abuts against the sliding block 41, the sliding block 41 is slidably mounted in the sliding chute 40, and the telescopic sleeve 25 is fixed on the sliding block 41, so that the position limiting assembly can slide back and forth along the sliding chute 40; the compression spring 42 of the present invention is compressed in a normal state, and has a smaller elastic force ratio, so as to be able to push the position-limiting component open, i.e. when the position-limiting component is compressed along the sliding groove 40 and enters the position of the notch 15 after being pressed by an external force, the position-limiting component tends to be pushed open outwards, and when the position-limiting component loses its constraint, the elastic force of the compression spring 42 is enough to push the position-limiting component out, and the elastic force of the compression spring 42 should not be too large. Due to the elastic force of the compression spring 42, the limiting component always tends to slide towards the outside of the rotating cylinder 7, and when the positions of the crescent groove 6 and the sliding hole 14 are aligned, the limiting component is jacked out by the compression spring 42 and jacked into the crescent groove 6. When the positions of the slide hole 14 and the notch 15 are opposite, the rotating cylinder 7 is rotated, one end of the limiting pin 23 with the cambered surface structure is abutted against the side wall of the crescent groove 6, the rotating cylinder 7 is continuously rotated, the limiting pin 23 and the crescent groove 6 interact integrally to press the limiting component into the notch 15, until the next crescent groove 6 is rotated, the limiting component is ejected out by the compression spring 42, the reciprocating operation is carried out, and if the positions of the slide hole 14 and the notch 15 are not opposite, the motion cannot occur.
