[0021] Specifically, a pressing roller 3 is rotatably provided at the bottom of the pressing plate 2 to reduce the wear between the cloth and the pressing plate 2. A handle 4 is fixedly provided on the front side of the pressing plate 2, and the pressing plate 2 can be conveniently lifted by the handle 4.

[0022] Specifically, the slider 7 is slidably connected to the inner wall of the slide groove 6 , and the compression spring 8 is sleeved on the connecting rod 9 , so as to improve the stability of the slider 7 in the slide groove 6 to compress the compression spring 8 and move upward.

[0023] Specifically, the clamping mechanism includes a pressure column 16, a screw rod 18 and a knob 20. The pressure column 16 is fixedly connected to the force spring 15. A threaded groove 17 is provided at one end of the pressure column 16 away from the force spring 15. The screw rod 18 is threadedly connected in the threaded groove 17. A rotating groove 19 is provided on the top seat 10 for the screw rod 18 to pass through and is rotatably connected to the screw rod 18. One end of the screw rod 18 located outside the top seat 10 is fixedly connected to the knob 20. The screw rod 18 is driven by rotating the knob 20. The threaded connection between the screw rod 18 and the threaded groove 17 causes the pressure column 16 to move, so that the pressure column 16 applies force to the force spring 15, the force spring 15 applies force to the adjusting block 13, the adjusting block 13 applies force to the connecting plate 12, the connecting plate 12 applies force to the connecting rod 9, the connecting rod 9 acts on the slider 7 and thus acts on the clamping plate 2, thereby adjusting the clamping force of the clamping plate 2.

[0024] Specifically, the pressure column 16 is located in the spring groove 14, the spring groove 14 is a square groove, the pressure column 16 is a square column and is slidably connected to the spring groove 14. The spring groove 14 is limited to prevent the pressure column 16 from rotating under the action of the screw 18, so that the pressure column 16 slides in the spring groove 14 to apply force to the force spring 15.

[0025] Specifically, a limit ring groove 21 is formed on the inner wall of the rotating groove 19, and a limit ring 22 fixedly sleeved on the screw rod 18 is rotatably arranged in the limit ring groove 21. The limit ring groove 21 and the limit ring 22 limit the screw rod 18 to avoid axial movement.

[0026] A specific application example of this embodiment is:

[0027] When the device is in use, the handle 4 is pulled to lift the pressing plate 2, and the pressing plate 2 drives the slider 7 to move up and compress the pressing spring 8. At the same time, the slider 7 drives the connecting rod 9 to move up, so that the connecting plate 12 moves up and compresses the force-applying spring 15, so that the cloth passes through the bottom of the pressing plate 2 and the pressing plate 2 is loosened. Under the elastic force of the compression spring 8, the slider 7 moves down and drives the pressing plate 2 to move down, so that the pressing roller 3 presses the cloth on the bottom plate 1. If it is necessary to increase the clamping force of the pressing plate 2 at this time, the knob 20 is turned to drive the screw 18 to rotate, and the screw 18 is threadedly connected with the threaded groove 17 to make the pressing column 16 move, so that the pressing column 16 acts on the force-applying spring 15, and the force-applying spring 15 acts on the adjusting block 13. The adjusting block 13 acts on the connecting plate 12, and the connecting plate 12 acts on the connecting rod 9. The connecting rod 9 acts on the slider 7 and thus acts on the pressing plate 2, thereby increasing the clamping force of the pressing plate 2 to meet the requirements of different clamping forces.
