[0053] Preferably, the top of the clamping arm 230 is provided with a chuck 231, which is used to clamp or release the positioning pin 240. Specifically, when the chuck 231 clamps the positioning pin 240, the positioning pin 240 is tightly connected to the surface module 100. When the chuck 231 releases the positioning pin 240, the positioning pin 240 is loosely connected to the surface module 100, thereby achieving the purpose of clamping or releasing the surface module 300.

[0054] Preferably, the lower part of the clamping arm 230 is hinged with the driving rod 220 through the driving pin 250, and the middle part of the clamping arm 230 is provided with a notch, and the fixed pin 260 passes through the notch and is connected with the fixed seat 210, so that when the driving rod 220 pushes the clamping arm 230, the clamping arm 230 can rotate around the driving pin 250, thereby realizing the opening or closing of the chuck 231.

[0055] Preferably, the profile clamping module 200 further comprises a compression spring 270 and a locking nut 280, the locking nut 280 is fixed at the bottom of the driving rod 220, the compression spring 270 is sleeved on the driving rod 220, and the two ends of the compression spring 270 respectively abut against the fixed seat 210 and the locking nut 280, and under the action of no external force, the compression spring 270 always provides a downward force to the driving rod 220 and makes the clamping arm 230 clamp the positioning nail 240, thereby realizing the function of automatic clamping without the need of an additional power source to maintain the clamping state.

[0056] Preferably, it further comprises a loosening profile module 300, which is arranged at the bottom of the profile clamping module 200, and the loosening profile module 300 comprises:

[0063] Specifically, the working principle of the clamping and loosening of the profile module 100 is as follows:

[0064] 1, clamping state: under the action of compression spring 270, drive rod 220 moves downward, through drive pin 250 to drive the clamping head 231 of clamping arm 230 to fold inward, clamp positioning nail 240, so that positioning nail 240 is connected with profile die set 100 tightly, so as to realize the clamping of product 110;
