A rack 15 is fixedly connected to the side of the sliding block 14. A gear 16 is meshed with the middle of the rack 15. A rotating shaft 17 is rotatably connected to the middle of the gear 16. A first fixing screw 18 is threadedly connected to the middle of the rotating shaft 17. A rotating bracket 19 is fixedly connected to the surface of the rotating shaft 17. A first fixing shaft 20 is provided at the end of the rotating bracket 19. A transmission bracket 21 is installed in the middle of the first fixing shaft 20. A second fixing shaft 22 is passed through the middle of the transmission bracket 21. A movable bracket 23 is installed in the middle of the second fixing shaft 22. A second fixing screw 24 is passed through the head of the movable bracket 23. A movable shaft 25 is fixedly connected to the surface of the second fixing screw 24. A clamping frame 26 is fixedly connected to the bottom of the transmission bracket 21.

[0022] Furthermore, the groove 3 has several sets of grooves in the middle of the support column 2, and the support plate 7 forms a locking structure with the support column 2 through the groove 3 and the protrusion 4, thereby realizing the adjustment function of the support plate 7 and meeting the work needs of different workers.

[0023] Furthermore, the clamping structure includes a sliding block 14, a rack 15, a gear 16, a rotating shaft 17, a first fixing screw 18, a rotating bracket 19, a first fixing shaft 20, a transmission bracket 21, a second fixing shaft 22, a movable bracket 23, a second fixing screw 24, a movable shaft 25, and a clamping frame 26, thereby driving the overall normal operation of the clamping structure.

[0024] Furthermore, the clamping structure forms a sliding structure with the lead screw 9 and the fixed plate 10, and the threads at both ends of the lead screw 9 are arranged opposite to each other, so that the clamping structure can perform relative linear sliding action in the slide groove 11 under the action of the lead screw 9 arranged opposite to each other at both ends.

[0025] Furthermore, the movable support 19 forms a rotating structure with the rotating shaft 17 via the rack 15, the gear 16, and the rack 17, so the rotating support 19 and the movable support 23 can move under the action of the rotating shaft 17 and the movable shaft 25.

[0027] Working principle: In use, firstly, the protrusion 4 is embedded into the groove 3 under the action of the spring 5, thus fixing the entire clamping structure. Grooves 3 of different heights are provided on the support column 2 to adjust the support plate 7 and meet the working needs of different workers. Next, the motor 8 is powered on, and the lead screw 9 rotates under the action of the motor 8 via the first fixed seat 12 and the second fixed seat 13. Thus, the clamping structure can slide linearly relative to each other in the slide groove 11 under the action of the lead screws 9 at both ends, ensuring the normal operation of the clamping structure and improving the working efficiency of the workers. To improve the efficiency of the workers, the first fixing screw 18 and the second fixing screw 24 are removed. When the lead screw 9 drives the gear 16 to rotate on the rack 15, the rotating bracket 19 and the movable bracket 23 move accordingly under the action of the rotating shaft 17 and the movable shaft 25. At the same time, the clamping frame 26 opens outward through the transmission bracket 21 integrated with it. When it is opened to a suitable angle, the first fixing screw 18 and the second fixing screw 24 are threadedly connected to the rotating shaft 17 and the movable shaft 25 respectively, which plays a role in fixing the clamping device, improving the stability of the device, and achieving the purpose of the clamping frame 26 accurately and stably clamping the material.
