[0023] In the first embodiment of the present invention, the fixed structure includes two support frames 61 fixedly installed on the top of the cutting machine 1, and the two support frames 61 are slidably installed with connecting blocks 62. The two support frames 61 include rectangular frames and limit bars, and the limit bars are fixedly installed on the rear side wall of the inner cavity of the rectangular frame. The back of the connecting block 62 is provided with a limit groove, and the outer surface of the limit bar is slidably connected to the inner wall of the limit groove, so as to limit the connecting block 62 to move up and down only on the outer surface of the limit bar. The two support frames 61 are provided with a lifting structure for controlling the up and down movement of the two connecting blocks 62. 63. The lifting structure 63 includes two electric push rods, which are fixedly installed on the inner bottom walls of the two support frames 61 respectively.

An installation frame 64 is fixedly connected between the opposite sides of the two connecting blocks 62. Two adjustment blocks 65 are slidably installed inside the installation frame 64. The front sides of the two adjustment blocks 65 are fixedly installed with clamping members 66 for clamping metal sheets, so as to fix the metal sheets.

[0024] The two clamping members 66 each include an L-shaped plate and a reinforcing plate. The L-shaped plate is fixedly mounted on the front side of the adjusting block 65, and the reinforcing plate is fixedly mounted on the L-shaped plate, so that the clamping members 66 can stably clamp the metal sheet.

[0025] In addition, the two adjustment blocks 65 each include a limit block and a mounting block. The limit block is fixedly installed at the bottom of the mounting block. A through groove is provided on the inner bottom wall of the mounting frame 64.
