[0035] The mounting portion 105 is provided with a slide groove 107, and one end of the rotating shaft 104 located in the mounting groove 106 is provided with a locking groove 108, and a locking component 109 is slidably installed in the slide groove 107 for locking the rotating shaft 104 after cooperating with the locking groove 108; the mounting portion 105 is threadedly connected with a driving ring 110, and a guide groove 111 is provided in the driving ring 110 for driving the locking component 109 to slide;

[0036] A knife holder 112 for mounting a cutting knife is fixedly connected to the rotating shaft 104 .

[0037] In the present invention, the mounting portion 105 is symmetrically arranged at the left and right ends of the frame 101, there are two slide grooves 107, and the locking grooves 108 are arranged one by one with the slide grooves 107; the rotating shaft 104 is arranged between the unwinding roller 102 and the winding device 103, and the unwinding roller 102 is used to wind the material to be cut; when it is necessary to cut the material, the operator first rotates the rotating shaft 104 so that the knife holder 112 fixedly connected to the rotating shaft 104 rotates with the rotating shaft 104 to the end away from the material, so that the operator can install the winding device 103 on the frame 101, and can avoid the knife holder 112 and the cutting knife installed on the knife holder 112 when the operator is cutting the material The end away from the unwinding roller 102 passes through the bottom of the rotating shaft 104 and adheres to the winding device 103, causing obstruction; by rotating the driving ring 110 threadedly connected to the mounting portion 105, the driving ring 110 can be moved horizontally toward the direction of the locking component 109; the guide groove 111 arranged on the driving ring 110 can drive the locking component 109 to move vertically downward into the locking groove 108 after contacting with the locking component 109, and the rotating shaft 104 can be limited and fixed by the cooperation between the locking component 109 and the locking groove 108, so that the operator can quickly and conveniently adjust the position of the tool holder 112 fixedly connected to the rotating shaft 104.

[0038] The locking assembly 109 includes a locking pin 113 and a spring 114 . The locking pin 113 is slidably installed in the slide slot 107 . A connecting block 115 is provided at one end of the locking pin 113 outside the slide slot 107 . The connecting block 115 is connected to the mounting portion 105 via the spring 114 . After the guide groove 111 moves horizontally to contact the connecting block 115, the connecting block 115 and the locking pin 113 fixedly connected to the connecting block 115 move vertically downward under the drive of the guide groove 111. At this time, the spring 114 connecting the connecting block 115 and the mounting portion 105 is compressed, and the locking pin 113 moves into the locking groove 108 to lock the rotating shaft 104; when the rotating shaft 104 needs to be rotated, the driving ring 110 is rotated to make the driving ring 110 move horizontally in the direction away from the locking pin 113.
