The first telescopic rod 12 is movably arranged in the sleeve 11, and the two are gap-fitted. The first fixed part 51 of the first clamping piece 5 is sleeved outside the sleeve 11. The outer diameter of the larger end of the first telescopic rod 12 is smaller than the inner diameter of the second fixed part 52 of the first clamping piece 5, so that the larger end of the first telescopic rod 12 can be achieved by interference fit. The second telescopic rod 12 is movably arranged in the first telescopic rod 12, and the two are gap-fitted. The first fixed part 51 of the second clamping piece 5 is sleeved on the smaller end of the first telescopic rod 12. The outer diameter of the larger end of the second telescopic rod 12 is smaller than the inner diameter of the second fixed part 52 of the second clamping piece 5, so that the larger end of the second telescopic rod 12 can be achieved by interference fit. The third telescopic rod 12 is movably arranged in the second telescopic rod 12, and the two are gap-fitted.
