Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-5 The present invention provides a technical solution: including a placement plate 1, a positioning mechanism 2 is provided above the placement plate 1, and an adjustment mechanism 3 is provided inside the placement plate 1;

[0030] Positioning mechanism 2 includes a positioning part and a pressing part;

[0031] The positioning part includes two positioning plates 21, and the pressing part includes two pressing plates 23 and a connecting rod 27;

[0032] The top surface of the placement plate 1 is slidably connected to the bottom surface of the two positioning plates 21. The adjacent sides of the two positioning plates 21 are slidably connected to the outer walls of the two pressure plates 23. Two grooves are respectively formed on the outer walls of the two positioning plates 21. Two connecting brackets 28 are slidably arranged on the inner walls of the two grooves. The sides of the two connecting brackets 28 closest to the two pressure plates 23 are fixedly connected to the outer walls of the two pressure plates 23. Two fixing sleeves 214 are fixedly arranged on the inner sides of the two connecting brackets 28. The inner sides of the two fixing sleeves 214 are slidably connected to the outer walls of the connecting rods 27. A double-axis threaded rod 29 is rotatably arranged on the inner side of the placement plate 1 via a bearing seat. Two control frames 210 are threadedly sleeved on the outer walls of the double-axis threaded rod 29. The outer walls of the two control frames 210 are slidably connected to the inner side of the placement plate 1. The top surfaces of the two control frames 210 are fixedly connected to the bottom surfaces of the two positioning plates 21. The outer wall of the textured rod 29 extends through the inner side of the placement plate 1 to the outer wall of the placement plate 1. A connecting rail 213 is fixedly installed on the outer wall of the placement plate 1. Two limiting sleeves 212 are slidably sleeved on the outer walls of the two connecting rails 213 respectively. Two limiting frames 211 are fixedly installed on the top surfaces of the two limiting sleeves 212 respectively. The outer walls of the two limiting frames 211 are fixedly connected to the outer walls of the two positioning plates 21 respectively. A fixing frame 26 is fixedly installed on the outer wall of the placement plate 1. A connecting sleeve 24 is slidably sleeved on the outer wall of the fixing frame 26. The bottom surface of the connecting sleeve 24 is fixedly connected to the top surface of the connecting rod 27. A pressing screw 25 is threaded on the outer wall of the connecting sleeve 24 and extends to the inner side of the fixing frame 26. Two wedge-shaped grooves are opened on the adjacent side of the two positioning plates 21 respectively. Two wedge-shaped blocks 22 are slidably installed on the inner walls of the two wedge grooves respectively. The adjacent side of the two wedge blocks 22 is fixedly connected to the outer walls of the two pressure plates 23 respectively.

[0033] The adjustment mechanism 3 includes an adjustment plate 31. The outer wall of the adjustment plate 31 is slidably connected to the inner side of the placement plate 1. Two limiting rods 32 are fixedly installed on the inner side of the placement plate 1. The outer walls of the two limiting rods 32 are slidably connected to the inner side of the placement plate 1. A through groove is opened through the outer wall of the placement plate 1. An adjustment frame 33 is slidably installed on the inner wall of the through groove. The side of the adjustment frame 33 near the adjustment plate 31 is fixedly connected to the outer wall of the adjustment plate 31. A threaded rod 34 is threaded on the inner side of the adjustment plate 31. The outer wall of the threaded rod 34 is rotatably connected to the outer wall of the placement plate 1 through a bearing seat 2.

[0034] In use, the two positioning plates 21 can slide on the top surface of the placement plate 1. After the patch back plate is placed on the placement plate 1, the double-axis threaded rod 29 is rotated. Since the outer wall of the double-axis threaded rod 29 is threaded with two control frames 210, and the top surfaces of the two control frames 210 are fixedly connected to the bottom surfaces of the two positioning plates 21 respectively, when the double-axis threaded rod 29 rotates, the two control frames 210 will move towards or away from each other along their thread direction, causing the two positioning plates 21 to slide on the top surface of the placement plate 1 until the patch back plate is initially limited to a suitable position. At the same time, the limiting frame 211 on the outer wall of the positioning plate 21 slides on the connecting rail 213 through the limiting sleeve 212 to ensure the stability and accuracy of the sliding of the positioning plate 21.

[0035] Once the position of the positioning plate 21 is determined, manually loosen the extrusion screw 25. After the extrusion screw 25 is loosened, the two pressure plates 23 will move downward under the action of gravity. When the two pressure plates 23 move downward, they will contact the patch back plate. After contact, tighten the extrusion screw 25 to achieve a stable fixation of the patch back plate. Furthermore, through the two connecting brackets 28, the two fixing sleeves 214, and the connecting rod 27, the two pressure plates 23 can be controlled synchronously after the two positioning plates 21 are adjusted.

[0036] The adjusting plate 31 can slide on the inner side of the placement plate 1. When the threaded rod 34 is rotated, the adjusting plate 31 will move along the inner side of the placement plate 1 because the threaded rod 34 is threadedly connected to the adjusting plate 31. The adjusting plate 31 drives other components to move synchronously through the adjusting frame 33 to adapt to the processing requirements of different specifications of patch backplates. At the same time, during the movement of the adjusting plate 31, the limiting rod 32 plays a limiting and guiding role to ensure the stability of the adjustment process.
