[0029] The second rotation limiting assembly comprises a plurality of vertical fixed rods 5, which are uniformly distributed along the circumference of the positioning column 3, and each of the fixed rods 5 is fixedly connected with the block.

[0030] A guide piece is arranged between the damping cylinder 4 and the mounting column 9, and is used to automatically align the limiting slot on the mounting column 9 with the fixed rod 5.

[0031] The guide piece comprises a plurality of guide blocks 11 and a plurality of positioning blocks 8. The plurality of guide blocks 11 are fixedly connected with the mounting column 9, and the plurality of positioning blocks 8 are fixedly connected with the inner wall of the damping cylinder 4. The plurality of positioning blocks 8 are uniformly distributed along the circumference of the positioning column 3, and correspond to the plurality of fixed rods 5 one by one. Each of the positioning blocks 8 is located on the same radial line of the positioning column 3 as the corresponding fixed rod 5.

[0032] The plurality of guide blocks 11 correspond to the plurality of positioning blocks 8 one by one, and each of the adjacent two guide blocks 11 corresponds to one positioning block 8 and one limiting slot.
