The fixing component 3 includes a fixing frame A31 arranged on one side of the workbench 1, a threaded rod A32 is rotatably provided on the fixing frame A31, an arc-shaped fixing plate A33 is fixedly provided at the end of the threaded rod A32, a telescopic cylinder B34 is fixedly provided on the workbench 1 on one side of the fixing frame A31, a fixing frame B35 is fixedly provided on the output end of the telescopic cylinder B34, a bidirectional threaded rod B36 is rotatably provided on the fixing frame B35, two arc-shaped fixing plates B37 are threadedly sleeved on the bidirectional threaded rod B36, a placement slot 8 is provided on the workbench 1, and a moving slot is provided on the workbench 1 on both sides of the placement slot 8, a moving block matching the moving slot is provided on the protective frame 42B, and a scale 9 is engraved on the front of the workbench 1.

[0027] The product is moved by the telescopic cylinder B34, and the length of the product is measured by the scale 9 on the workbench 1, so as to ensure the accuracy of its cutting. At the same time, the motor 43 drives the cutting blade 44 and the fan 48 to rotate, so as to achieve cooling of the motor 43 and the cutting blade 44, thereby increasing their service life. The wind force generated by the fan 48 blows the debris into the waste box 7 to achieve cleaning of the workbench 1, thereby reducing the workload of cleaning the workbench 1 and improving its cutting efficiency.
