Through the cooperation of the T-shaped frame 61, the U-shaped block 62 and the threaded shaft 63, the first handle 4 and the second handle 5 can be connected.
[0025] Specifically, the clamping plate 64 is sleeved with the surface of the threaded shaft 63 , and the extrusion nut 65 is threadedly connected with the surface of the threaded shaft 63 .
[0026] In this embodiment, the clamping plate 64 can squeeze the damping gasket 66 against the side surface of the T-shaped block under the action of the squeezing nut 65 and the threaded shaft 63.
[0027] Specifically, the damping gasket 66 abuts against the side surface of the T-shaped frame 61 . By clamping the damping gasket 66 on the side surface of the T-shaped frame 61 , the stability of the T-shaped frame 61 can be increased and the probability of the T-shaped frame 61 rotating automatically can be reduced.
