[0028] Embodiment 2

[0029] On the basis of the first embodiment, the limiting assembly 4 includes a first vertical plate 9, a second vertical plate 10, a connecting plate 12, an insertion rod 31 and a connecting spring 15. The first vertical plate 9 and the second vertical plate 10 are both fixed to the surface of the protective cover 5. The surface of the first vertical plate 9 is provided with a second through hole 8, and the surface of the second vertical plate 10 is provided with a first through hole 11. The insertion rod 31 is inserted into the first through hole 11 and the second through hole 8;

[0030] The end surface of the insertion rod 31 is fixed with a connection plate 12, and the surface of the insertion rod 31 is sleeved with a connection spring 15, one end of the connection spring 15 is fixedly connected to the connection plate 12, and the other end of the connection spring 15 is fixedly connected to the second vertical plate 10, and the surface of the connection plate 12 is fixed with a second handle 14, and the interior of the second handle 14 is provided with an anti-slip pattern 13;

The operation is relatively convenient. The initial protective texture can increase friction to avoid slipping when the first handle 1 and the second handle 14 are toggled, thereby improving the stability of the operation.

[0033] Embodiment 3

[0034] On the basis of the second embodiment, one end of the support spring 24 is fixedly connected to the receiving plate 23, and the other end of the support spring 24 is fixedly connected to the bottom of the protective sleeve 5. The inner concave cavity 27 is used to receive the pin blade 18. The inner surface of the protective sleeve 5 is provided with a lateral ball groove 20, and the lateral ball groove 20 is adapted to the movable ball 22. A limit block 26 is fixed to the upper end of the support column 25, and the limit block 26 is located above the receiving plate 23. The support frame 17 is fixed to the middle of the protective sleeve 5. A rubber strip 16 is fixed inside the support frame 17. The rubber strip 16 is provided in a plurality of groups, and the plurality of groups of rubber strips 16 are evenly distributed inside the support frame 17.
