[0025] A cutter 16 is provided between the two positioning boxes 2, and a rotating shaft 11 connected to the cutter 16 is rotatably provided in the middle part of the two positioning boxes 2. A second motor is fixedly provided inside one of the positioning boxes 2, and a second drive shaft connected to one of the rotating shafts 11 is provided at the output end of the second motor. A fixing ring 14 for limiting the position of the cutter 16 is provided on the inner side of the positioning box 2, and a plurality of balls 15 for contacting the cutter 16 are provided on the circumference of the fixing ring 14.

[0026] In this embodiment, the second motor is started to enable the rotating shaft 11 to drive the cutter 16 to rotate between the two positioning boxes 2. During this process, a designated plate workpiece is taken and pushed on the processing table 1, so that the cutter 16 can cut the plate workpiece into a designated size on the processing table 1.

[0027] During the rotation of the cutter 16, the two fixed rings 14 provide a clamping and fixing structure for the cutter 16, thereby improving the stability of the cutter 16 during use and preventing the cutter 16 from breaking.

The positioning ring 12 is fixed to the inner side of the positioning box 2 by screws. The screw fixing method can facilitate the assembly of the positioning ring 12 on the positioning box 2, thereby making it easy to replace the fixing ring 14.
