[0026] Furthermore, a slide rail 414 is fixedly installed on one side of the connecting plate 413, and a rolling wheel 419 is movably engaged with the inner wall of the slide rail 414.

[0027] Furthermore, a plurality of sets of snap-fit ​​blocks 711 are fixedly mounted on the inner wall of the mounting groove 7, and the top ends of the plurality of snap-fit ​​blocks 711 are arc-shaped. The design of the snap-fit ​​blocks 711 and the snap-fit ​​groove 511 provides preliminary positioning and stability, so that the connecting base 5 can be quickly and accurately installed in the mounting groove 7, thereby simplifying the installation process and improving the installation efficiency.

[0028] Furthermore, the outer side of the connection base 5 is provided with a plurality of sets of snap-fit ​​grooves 511. When the snap-fit ​​grooves 511 are used in conjunction with the snap-fit ​​blocks 711 in the installation groove 7, it can ensure that the connection base 5 has higher precision and accuracy during installation, thereby reducing errors during installation.

[0031] Furthermore, the outer surface of the top end of the buffer plate 8 is wrapped with rubber, and the softness of the rubber can also reduce the friction and wear between the connection base 5 or the buffer plate 8 .

[0032] Working principle: First, the connection base 5 is preliminarily installed in the mounting groove 7 by cooperating with the multiple groups of corresponding snap blocks 711 on the inner wall of the mounting groove 7 at the top of the connection frame 1 through the multiple groups of snap grooves 511 set at the bottom thereof. The design of the snap grooves 511 and the snap blocks 711 ensures the initial positioning and stability of the base during installation. Next, the cylinder 411 in the locking mechanism 4 is started. After receiving the driving signal, the piston of the cylinder 411 begins to move upward. The piston rod of the cylinder 411 is connected to the connecting rod 415, so the movement of the piston drives the upward movement of the connecting rod 415. The other end of the connecting rod 415 is connected to the push block 417. A through groove is provided in the middle of the push block 417, in which a rolling wheel 419 is installed. The rolling wheel 419 rolls on the slide rail 414, reducing the friction force and ensuring that the push block 417 can move smoothly and accurately along the slide rail 414. As the push block 417 moves upward, the two groups of linkage rods 418 begin to play a role. One end of the linkage rod 418 is connected to the push block 417, and the other end is connected to the round rod 420. Therefore, the movement of the push block 417 drives the rotation of the round rod 420. The rotation of the round rod 420 further drives the movement of the triangular connecting plate 421. The triangular connecting plate 421 is installed at both ends of the limit plate 412 through the shaft 416, so it can rotate around the shaft 416. As the round rod 420 rotates, the triangular connecting plate 421 gradually unfolds from the initial position and finally presents a right angle state of 90 degrees. When the triangular connecting plate 421 reaches the right angle state of 90 degrees, the cross plate 422 connected thereto also moves to a suitable position. At this time, the locking block 423 at the bottom end of the cross plate 422 can be accurately engaged in the fixing groove 512 at the top of the connecting base 5. The locking block 423 applies pressure to the fixing groove 512, thereby firmly locking the connecting base 5 in the mounting groove 7.

[0033] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
