[0023] Further as Figure 1 and Figure 2 As shown, it is worth explaining in detail that the bottoms of the multiple support feet 2 are fixedly connected with anti-skid pads, which have the effect of anti-skid and shock absorption, so that the bottom groove 1 always remains stable during the entire processing process, thereby improving the stability of LCD display production work.

[0024] Further as Figure 2 and Figure 3 As shown, it is worth specifically explaining that the output end of the servo motor 11 passes through the mounting plate 4 and is fixedly connected to the bidirectional threaded rod 5, ensuring that the servo motor 11 can drive the bidirectional threaded rod 5 to rotate smoothly, thereby providing driving force for the movement of the ball nut seat 7.

[0025] Further as Figure 1 and Figure 2 As shown, it is worth explaining in detail that the worm 14 is meshed with the worm wheel 12 to ensure that the worm 14 can drive the worm wheel 12 to rotate. At the same time, the transmission of the worm wheel 14 and the worm 12 has a self-locking characteristic, which can effectively prevent reverse rotation and increase the safety of the device.

[0026] According to the above working process, it can be known that: by setting the worm wheel 14 and the worm 12 to cooperate with each other, when the angle of the LCD display needs to be changed during processing, the crank 15 is turned to drive the worm 12 to rotate, so that the worm wheel 14 drives the rotating shaft 3 to rotate, thereby making the L-shaped support plate 9 rotate to drive the LCD display to flip and change the angle, which can be flexibly coordinated according to actual production needs, thereby improving the processing effect. At the same time, the transmission of the worm wheel 14 and the worm 12 has a self-locking feature, which can effectively prevent reversal and increase the safety of the device; by setting the servo motor 11 to drive the bidirectional threaded rod 5 to rotate, with the cooperation of the ball nut seat 7 and the guide ring 8, the two L-shaped support plates 9 are driven to shrink inward, so that LCD display screens of different specifications and sizes can be clamped and fixed.

[0028] Further as Figure 4As shown, it is worth explaining in detail that the spring 1004 is fixedly connected between the inner side of the slide plate 1002 and the inner wall of the sleeve 1003. Under the action of the spring 1004, the round rod 1001 and the slide plate 1002 can slide flexibly on the inner wall of the sleeve 1003.

[0029] Further as Figure 4 As shown, it is worth explaining in detail that an anti-slip strip is fixedly connected to the inner side of the clamping plate 1005, which can increase the friction between the clamping plate 1005 and the LCD display screen, making the clamping of the LCD display screen more stable.

[0030] This solution has the following working process: in actual use, the LCD display screen is placed on the top of the two L-shaped support plates 9, and the servo motor 11 is turned on to drive the bidirectional threaded rod 5 to rotate, thereby driving the two L-shaped support plates 9 to retract inward, and LCD display screens of different sizes can be clamped and fixed. When the angle of the LCD display screen needs to be changed during processing, the crank 15 is turned to drive the worm 12 to rotate, so that the worm gear 14 drives the rotating shaft 3 to rotate, thereby causing the L-shaped support plate 9 to rotate and drive the LCD display screen to flip and change the angle.

[0031] In summary: by arranging the worm wheel 14 and the worm 12 to cooperate with each other, the angle of the LCD display screen can be flexibly changed according to actual production needs, thereby improving the processing effect. At the same time, the transmission of the worm wheel 14 and the worm 12 has a self-locking feature, which can effectively prevent reversal and increase the safety of the device; by arranging the servo motor 11 to drive the bidirectional threaded rod 5 to rotate, with the cooperation of the ball nut seat 7 and the guide ring 8, the two L-shaped support plates 9 are driven to retract inward, so that LCD display screens of different specifications and sizes can be clamped and fixed; by arranging the buffer mechanism 10, the clamping force exerted on the LCD display screen has a certain buffering effect, thereby avoiding damage to the LCD display screen during hard clamping.
