[0017] The ends of the material are clamped by two sets of clamping mechanisms 300, so that the longer material can remain stable during the movement. At the same time, the material can be flipped by the flip assembly 200 to adjust the position of the material surface to be processed for easy processing.

[0018] Reference Figure 4 As shown, the clamp mechanism 300 includes a fixed plate 310, a first movable seat 320, a second movable seat 330, a clamping jaw assembly 340, and an opening and closing assembly 350. The fixed plate 310 is connected to the connecting frame 400. The first movable seat 320 and the second movable seat 330 are slidably installed on the fixed plate 310. The first movable seat 320 and the second movable seat 330 are respectively installed with a clamping jaw assembly 340, and the two clamping jaw assemblies 340 are arranged opposite to each other. The opening and closing assembly 350 is used to move the movable seat to cause an opening and closing action between the first movable seat 320 and the second movable seat 330 to achieve the clamping and releasing of the material.

[0019] Reference Figure 5 , 6 As shown, the opening and closing component 350 includes an opening and closing cylinder 351, a rack 352, and a gear 353.

A rack 352 is respectively installed on the first movable seat 320 and the second movable seat 330, and a gear 353 is meshed between the two racks 352.

[0020] During operation, the first movable seat 320 is pushed by opening and closing the cylinder 351, so that the rack 352 mounted on the first movable seat 320 moves, and drives the gear 353 to rotate counterclockwise, thereby moving another rack 352 mounted on the second movable seat 330. At this time, the first movable seat 320 and the second movable seat 330 move in opposite directions, thereby realizing the clamping of the material by the two clamping jaw assemblies 340.

[0021] On the contrary, by opening and closing the cylinder 351 to pull the first movable seat 320, the rack 352 mounted on the first movable seat 320 drives the gear 353 to rotate clockwise, thereby moving the other rack 352 mounted on the second movable seat 330.
