When the staff finds that the blade 10 needs to be replaced, the staff can rotate the rotating rod 21 to make the rotating rod 21 drive the first bevel gear 22 to rotate, and the first bevel gear 22 drives the third threaded rod 19 to rotate by meshing with the second bevel gear 20, so that the third threaded rod 19 drives the sliding block 13 to slide up and down inside the telescopic block slide 15, and the blade fixing block 9 slides up and down inside the fixed block slide 25. When the blade fixing block 9 slides upward inside the fixed block slide 25, one side of the telescopic block 11 is moved away from the telescopic block slide The inside of the slot 15 pops out of the telescopic block slide slot 15 through the action of the first spring 16, and the squeezing and fixing of the blade 10 by the squeezing plate 14 is released. The staff can now replace the blade 10 through the cutting column extension slot 5 opened on the surface of the winding frame 1. When the staff rotates the rotating rod 21 to make the blade fixing block 9 move downward in the telescopic block slide slot 15, the inclined surface on one side of the telescopic block 11 will be squeezed by the inner wall of the fixing block slide slot 25, and then the telescopic block 11 slides toward the inside of the telescopic block slide slot 15, and the telescopic block 11 slides toward the direction of the blade placement slot 12, so that the second spring 17 squeezes the squeezing plate 14, so that the squeezing plate 14 squeezes the surface of the blade 10, thereby squeezing and fixing the blade 10 placed in the blade placement slot 12.
