In this embodiment, an outer convex ring 23 is disposed at one end of the screw 21 facing the inner clamping block 22, and the outer diameter of the outer convex ring 23 is the same as that of the loop bar 11. Specifically, when the flexible sleeve 4 is in an unclamped state, the axial length of the flexible sleeve is longer than that of the sleeve rod 11, and before clamping, the inner clamping block 22 is separated from the inner end surface of the sleeve rod 11, so that the outer convex ring 23 can be filled in one end of the flexible sleeve 4 facing the inner clamping block 22, the end part of the flexible sleeve 4 is not excessively contracted inwards when being clamped, unnecessary deformation is generated, the flexible sleeve 4 is easy to damage, and the flexible sleeve is inconvenient to reuse.
