The rotation of the threaded rod 453 can drive the support frame 421 to move back and forth.

[0035] Working principle: When patch is required, the workpiece can be transported to the bottom end of the patch machine 3 through the conveyor belt 2 first, and then the electric push rod 411 can be started to push the slide 412 to move it forward. The slide 412 will pull the closing plate 415 through the protective spring 416 to drive the slide bar 414 to move forward. The forward movement of the slide bar 414 will drive the extrusion plate 413 to move forward synchronously. The forward movement of the extrusion plate 413 will push the workpiece to move forward. The forward movement of the workpiece will squeeze the extrusion block 4210 to drive the V-frame 429 to rotate. The rotation of the V-frame 429 will squeeze the workpiece through another set of extrusion blocks 4210 to move it to the middle position. When the front end of the workpiece is in contact with the rear end of the support frame 421, the workpiece will be fixed and cannot move.

[0036] When it is necessary to fix workpieces of different sizes, the positioning block 424 can be driven to disengage from the inner wall of the positioning groove 422 by pressing the lever 425, and then the support rod 423 can be moved left and right to change the fixed position. When the support rod 423 has finished moving, the lever 425 can be released, and the positioning spring 426 will push the positioning block 424 to reinsert it into the interior of the positioning groove 422. In this way, the position of the support rod 423 can be adjusted, and the position of the V-shaped frame 429 will also change accordingly, so that it can adapt to workpieces of different sizes.

[0037] When the front and rear position of the fixed point needs to be adjusted, the threaded rod 453 can be rotated by rotating the knob 454. The rotation of the threaded rod 453 can drive the adjustment sleeve 451 to move back and forth, thereby driving the support frame 421 to move back and forth. By changing the front and rear position of the support frame 421, the front and rear position of the fixed point can be changed.
