The movement control group (32) contracts the total length and simultaneously controls the axial movement control group (32) abutting against the second bevel (224) to return the total length for the purpose of rotating the inner casing (20). - Enter one Step, the first bevel (222) and the second bevel (224) may also be formed in the groove of the ring sidewall of the inner casing (20), as shown in the fifth figure. The ring side wall of the inner casing (20) of the second preferred embodiment comprises two grooves φ obliquely opposite to each other (which may also be through grooves), and one groove side of the two grooves respectively forms a first oblique side (222A) And a second oblique side (224A). Further, the guiding position of the guiding groove (12) and the first oblique side (222, 222A), the second oblique side (224, 224A) may also be reversed. In other words, the first bevel (222, 222A) and the second bevel (224, 224A) may be disposed on the outer casing (1) and the guide (12) may be disposed in the inner casing ( 20), causing the movable jaw (322) to move along the guide slot (12), causing relative movement of the outer casing (彳〇) and the inner casing (20).
