The arc-shaped clamping plate A13 is arranged on the inner side of the side cover 2, and the rack A123 is connected to the arc-shaped clamping plate A13. The two racks A123 are meshed with the gear A122. The inner ends of the side cover 2 are both connected with a guide rod 14. The two arc-shaped clamping plates A13 are connected to the inner side of the side cover 2. They are both slidably installed on the two guide rods 14, and the servo motor A121 is started to drive the gear A122 to rotate. The rotation of the gear A122 drives the two racks A123 to move synchronously, and the two racks A123 respectively drive the two arc-shaped clamping plates A13 to move, and the two arc-shaped clamping plates A13 are driven to approach each other, so as to achieve the fixation of the end cover; a base B52 is provided directly below the two side covers 2, and a support rod 6 is connected between the base B52 and the side cover 2 on the corresponding side; two linear drive mechanisms B7 are respectively installed at both ends of the base A51 and are respectively used to drive the base B52 on both sides to move.
