Sleeve 9, a retaining ring 10 is provided at the end of the inner cylinder 1 away from the pressure cap, and a steel ball retainer 11 is provided between the retaining ring 10 and the tapered sleeve 9, which is sleeved on the top and embedded in the inner cylinder. The tapered sleeve 9 is provided with a side hole 12 opened on the inner cylinder 1, and the side holes 12 are distributed around the inner cylinder 1. A clamping arm 13 corresponding to the side holes 12 is rotatably connected in the outer cylinder 2. The lower end of the clamping arm 13 extends out of the outer cylinder 2 and has a chuck 14. The upper end of the clamping arm 13 has a driving part 15 that partially extends into the side hole 12 and resists the tapered sleeve 9.
