[0022] A transverse sliding groove is provided inside the transverse support column 1, and the first rigid spring 11 is located inside the transverse sliding groove. The rectangular sliding block 8 is located inside the transverse sliding groove and is slidably connected to the transverse support column 1 through the setting of the transverse sliding groove. Through the setting of the transverse sliding groove, the rectangular sliding block 8 can slide inside the transverse support column 1.

[0023] The buffer mechanism also includes an arc-shaped sliding plate 9, the outer side of the rectangular sliding block 8 is sleeved with the arc-shaped sliding plate 9, the top of the arc-shaped sliding plate 9 is fixed with a first circular fixing block 12, the top of the transverse support column 1 is fixed with a second circular fixing block 13, a hydraulic cylinder 14 is arranged between the first circular fixing block 12 and the second circular fixing block 13, and a second rigid spring 15 is arranged between the first circular fixing block 12 and the second circular fixing block 13 and on the outer side of the hydraulic cylinder 14;

[0024] When the rotation of the V-shaped support frame 4 enables the vertical rotation axis 3 to rotate, the rotation of the vertical rotation axis 3 enables the rectangular rotation column 6 to rotate, and the rotation of the rectangular rotation column 6 passes through the rectangular transmission column 7, so that the rectangular sliding block 8 can slide on the outside of the transverse light rod 10, and the sliding of the rectangular sliding block 8 causes the first rigid spring 11 to be deformed by force. Through the setting of the first rigid spring 11, it can provide resistance to the rotation of the V-shaped support frame 4 to prevent the V-shaped support frame 4 from rotating excessively. The sliding of the rectangular sliding block 8 passes through the arc-shaped sliding plate 9, so that the second rigid spring 15 can be deformed by force. Through the setting of the hydraulic cylinder 14 and the second rigid spring 15, the rotation force of the V-shaped support frame 4 can be slowed down to prevent the V-shaped support frame 4 from being damaged due to excessive rotation.

[0025] The limiting mechanism includes a rectangular mounting frame 16, a rectangular mounting frame 16 is fixed to one side of the transverse support column 1 away from the V-shaped support frame 4, a first transverse threaded rod 18 is arranged inside the rectangular mounting frame 16, a second transverse threaded rod 19 is fixed to one end of the first transverse threaded rod 18, the first transverse threaded rod 18 and the second transverse threaded rod 19 have opposite thread rotation directions, and the outer sides of the first transverse threaded rod 18 and the second transverse threaded rod 19 are both threadedly connected with a rectangular limiting plate 17, and the rectangular limiting plate 17 is located inside the rectangular mounting frame 16 and is slidably connected to the rectangular mounting frame 16;

Anti-slip grooves are also provided on the outside of the rectangular mounting frame 16. The anti-slip grooves are set so that the user can better rotate the rotating roller 20. The rotation of the rotating roller 20 enables the first transverse threaded rod 18 and the second transverse threaded rod 19 to rotate. The rotation of the first transverse threaded rod 18 and the second transverse threaded rod 19 enables the rectangular limiting plate 17 to move inside the rectangular mounting frame 16. Then, by adjusting the distance between the two rectangular limiting plates 17, the moving stroke of the arc sliding plate 9 can be limited, thereby limiting the rotation range of the V-shaped support frame 4.

[0027] Working principle: The rotation of the rotating roller 20 enables the first transverse threaded rod 18 and the second transverse threaded rod 19 to rotate, and the rotation of the first transverse threaded rod 18 and the second transverse threaded rod 19 enables the rectangular limit plate 17 to move inside the rectangular mounting frame 16, and then by adjusting the distance between the two rectangular limit plates 17, the moving stroke of the arc-shaped sliding plate 9 can be limited, and then the rotation range of the V-shaped support frame 4 can be limited;

[0028] When the rotation of the V-shaped support frame 4 enables the vertical rotation axis 3 to rotate, the rotation of the vertical rotation axis 3 enables the rectangular rotation column 6 to rotate, and the rotation of the rectangular rotation column 6 is through the rectangular transmission column 7, so that the rectangular sliding block 8 can slide on the outside of the transverse light rod 10, and the sliding of the rectangular sliding block 8 causes the first rigid spring 11 to be deformed by force. Through the setting of the first rigid spring 11, it can provide resistance to the rotation of the V-shaped support frame 4 to prevent the V-shaped support frame 4 from rotating excessively. The sliding of the rectangular sliding block 8 passes through the arc-shaped sliding plate 9, so that the second rigid spring 15 can be deformed by force. Through the setting of the hydraulic cylinder 14 and the second rigid spring 15, the rotation force of the V-shaped support frame 4 can be slowed down to prevent the V-shaped support frame 4 from being damaged due to excessive rotation.
