[0024] By adopting the above technical solution, the structure can limit the position of the rotating frame assembly 4 to a certain extent through the cooperation of the connecting sleeve 25 and the clamping block 26 when necessary, thereby preventing the rotating frame assembly 4 from deviating from the original position during the rotation process.

[0025] Specifically, the outer side of the clamping block 26 and the inner side of the connecting sleeve 25 are both prismatic in design, and the shape and size of the outer side of the clamping block 26 are the same as the shape and size of the inner side of the connecting sleeve 25 .

[0026] By adopting the above technical solution, the structure can ensure that the outer side of the clamping block 26 and the inner side of the connecting sleeve 25 are in close contact with each other, thereby preventing the clamping block 26 from shaking, thereby ensuring normal operation.

[0027] Specifically, the buffer assembly 22 includes a damper 221 and an elastic rubber frame 222. The elastic rubber frame 222 is installed between the outer top surface of the connecting platform 3 and the inner top surface of the connecting frame 21.
