The worm 51 is provided to drive the worm wheel 53 to rotate, and the worm 51 is meshed with the worm wheel 53. The worm wheel 53 cooperates with the worm 51 by setting the worm wheel 53. When the worm 51 does not rotate, the worm wheel 53 is in a self-locking state to prevent loosening. The inner ring of the worm wheel 53 is fixedly connected with a bidirectional threaded rod 54, and the bidirectional threaded rod 54 is set to rotate and simultaneously drive two support blocks 55 to move in opposite directions in both directions. The bidirectional threaded rod 54 is threadedly connected with a support block 55, and the front outer wall of the support block 55 is hinged with a guide roller 56. By setting the guide roller 56, the bending angle of the accessory is adjusted according to the distance between the two.

The top end of the worm 51 is fixedly connected to a movable disk 52, and the worm 51 is conveniently rotated by setting the movable disk 52. The side outer wall of the movable disk 52 is provided with an indication mark, and the operation method is prompted by setting the indication mark. The two ends of the bidirectional threaded rod 54 are rotatably connected to the inner walls on both sides of the mold frame 1 through bearings. There are two support blocks 55, and the two support blocks 55 are symmetrical respectively. The rear outer wall of the mold frame 1 is fixedly connected to the frame 2, and the frame 2 is raised and lowered by setting the frame 2. The front outer wall of the frame 2 is slidably connected to the bending machine 3, and the extrusion head 4 is driven by the bending machine 3 to extrude. The output end of the bending machine 3 is fixedly connected to the extrusion head 4, and the accessories are extruded and bent by setting the extrusion head 4.

[0026] Reference Figure 4 The anti-bias mechanism 6 includes a sliding frame 61, which is slidably connected to the left inner wall of the mold frame 1. The front inner wall of the sliding frame 61 is slidably connected with a paddle 62. The paddle 62 is provided to facilitate the separation, movement and disassembly of the sliding frame 61. The top outer wall of the paddle 62 is fixedly connected to a limiting rod 63. The limiting rod 63 is provided to clamp and limit the sliding frame 61.
