[0026] Multiple groups of clamping blocks 7 are arranged at the top of the clamping rod 6, multiple groups of slots 10 are arranged inside the clamping sleeve 9 and are adapted to the multiple groups of clamping blocks 7. The adaptation design of the clamping blocks 7 and the slots 10 ensures accurate positioning and connection, and the multiple-group design increases the reliability and stability of the connection.

[0027] Multiple groups of resisting pieces 11 are arranged obliquely in the multiple groups of slots 10, and the multiple groups of resisting pieces 11 are all elastic pieces. The elastic design of the oblique installation increases the self-adaptive ability of the resisting pieces 11 to adapt to different connection situations.

[0028] Multiple groups of clamping blocks 13 are arranged and slidably installed on the clamping sleeve 9, push springs 15 are arranged at the outer ends of the multiple groups of clamping blocks 13, both ends of the multiple groups of push springs 15 are respectively connected to the outer ends of the multiple groups of clamping blocks 13 and the clamping sleeve 9, multiple groups of clamping grooves 8 are distributed on the outer wall of the clamping rod 6 and are all adapted to the inner ends of the clamping blocks 13.

When the pneumatic clamping jaws 5 need to be installed, the locking sleeve 14 is moved upward along the sliding rod 16, and at the same time, multiple groups of compression springs 17 are squeezed. The movement of the locking sleeve 14 releases the abutment against the outer ends of multiple groups of clamping blocks 13.

Then, multiple groups of clamping blocks 7 are aligned with multiple groups of slots 10 and inserted. Due to the elastic characteristics of multiple groups of abutting pieces 11, the outer sides of multiple groups of clamping blocks 7 push the abutting pieces 11 upward. When multiple groups of clamping blocks 7 are inserted into the top grooves 12, they are separated from multiple groups of abutting pieces 11. At this time, multiple groups of abutting pieces 11 are elastically reset and abut against the bottom surfaces of multiple groups of clamping blocks 7 through their tops. Then, the locking sleeve 14 is released. Multiple groups of compression springs 17 are elastically reset to push the locking sleeve 14 to slide along the sliding rod 16, and the inner wall of the locking sleeve 14 abuts against the outer ends of multiple groups of clamping blocks 13 and applies a downward pressure, so that the inner ends of multiple groups of clamping blocks 13 are clamped in the clamping grooves 8 to limit and fix the clamping rod 6, and the installation of the pneumatic clamping jaws 5 can be completed. When the pneumatic clamping jaws 5 need to be disassembled, similarly, the locking sleeve 14 is pulled to release the abutment against multiple groups of clamping blocks 13, and then the clamping sleeve 9 is rotated so that multiple groups of clamping blocks 7 rotate in the top grooves 12. When multiple groups of clamping blocks 7 rotate to the position of the out grooves 18, the clamping sleeve 9 can be separated from the clamping rod 6, and the disassembly of the pneumatic clamping jaws 5 can be completed.

[0032] Please refer to Figure 1, as an implementation of the lifting mechanism: The lifting mechanism includes a mounting base 19, a hydraulic cylinder 20, a transmission block 21, and a mounting plate 22. There are two groups of them installed at both ends of the support pillar 1. The hydraulic cylinder 20 is installed on the top surface of the mounting base 19 and its telescopic end extends out of the mounting base 19. The transmission block 21 is installed on the telescopic end of the hydraulic cylinder 20. The mounting plate 22 is installed on the transmission block 21 and is fixedly connected to the flipping motor 2. The hydraulic cylinder 20 provides precise lifting control, improving the positioning accuracy. The connection design between the mounting plate 22 and the flipping motor 2 increases the flexibility of the system and enables multi-angle adjustment.

[0033] A limiting rod 23 is provided between the two groups of mounting bases 19. There are two groups of limiting rods 23 and they are slidably connected to the transmission block 21. The design of the limiting rod 23 increases the stability during the lifting process.

[0034] More specifically, start the hydraulic cylinder 20 to make its telescopic end extend. By the extension of the telescopic end of the hydraulic cylinder 20, the transmission block 21 is pushed to slide along the limiting rod 23, which can drive the display screen clamped by the pneumatic gripper 5 to descend. On the contrary, control the hydraulic cylinder 20 to make its telescopic end retract, so that the telescopic end of the hydraulic cylinder 20 pulls the transmission block 21 to rise, and then the display screen clamped by the pneumatic gripper 5 can be lifted.

[0035] During use: The display screen is clamped by starting the gripper. Then start the flipping motor 2 to drive the connecting shaft 3 to rotate. The connecting shaft 3 drives the mounting bracket 4 to rotate. The mounting bracket 4 drives the display screen clamped by the pneumatic gripper 5 to perform a rotation and flipping operation, so as to flip the display screen. When the pneumatic gripper 5 needs to be installed, move the lock sleeve 14 upward along the sliding rod 16, and at the same time squeeze a plurality of compression springs 17. The movement of the lock sleeve 14 releases the abutment against the outer ends of the plurality of clamping blocks 13. The plurality of pushing springs 15 push the plurality of clamping blocks 13 to extend outward. Then align the plurality of clamping blocks 7 with the plurality of slots 10 and insert them. Due to the elastic characteristics of the plurality of abutting pieces 11, the outer sides of the plurality of clamping blocks 7 push the abutting pieces 11 outward. When the plurality of clamping blocks 7 are inserted into the top groove 12, they are separated from the plurality of abutting pieces 11. At this time, the plurality of abutting pieces 11 are elastically reset and abut against the bottom surface of the plurality of clamping blocks 7 through their tops. Then release the lock sleeve 14. The plurality of compression springs 17 are elastically reset to push the lock sleeve 14 to slide along the sliding rod 16, and the inner wall of the lock sleeve 14 abuts against the outer ends of the plurality of clamping blocks 13 and applies a downward pressure, so that the inner ends of the plurality of clamping blocks 13 are clamped in the clamping groove 8 to limit and fix the clamping rod 6, and thus the installation of the pneumatic gripper 5 is completed. When the pneumatic gripper 5 needs to be disassembled, similarly pull the lock sleeve 14 to release the abutment against the plurality of clamping blocks 13, and then rotate the clamping sleeve 9 so that the plurality of clamping blocks 7 rotate in the top groove 12. When the plurality of clamping blocks 7 rotate to the position of the out groove 18, the clamping sleeve 9 can be separated from the clamping rod 6, and thus the disassembly of the pneumatic gripper 5 is completed.

[0036] Start the hydraulic cylinder 20 to extend its telescopic end. By pushing the transmission block 21 to slide along the limit rod 23 through the extension of the telescopic end of the hydraulic cylinder 20, the display screen clamped by the pneumatic gripper 5 can be driven to descend. On the contrary, control the hydraulic cylinder 20 to retract its telescopic end, so that the telescopic end of the hydraulic cylinder 20 pulls the transmission block 21 to rise, and the display screen clamped by the pneumatic gripper 5 can be raised.
