[0023] The combination of the limiting slide rail 4 and the limiting slider 5 enables the toggle block 7 to move in the limiting slide rail 4. The combination of the transmission rod 6, the connecting rod 9 and the cutting blade 10 enables the toggle block 7 to move when the toggle block 7 moves, thereby enabling the connecting rod 9 to drive the cutting blade 10 to move. The combination of the rotating shaft 11 and the limiting piece 12 enables the cling film to be sleeved on the surface of the rotating shaft 11 first, and then the limiting piece 12 is rotated and screwed into the top of the rotating shaft 11, thereby completing the limiting.

[0024] Furthermore, a limiting groove 13 is provided below the surface of the working box 2, a cutting table 14 is installed inside the limiting groove 13, and a cutting blade 10 is located inside the limiting groove 13, and the cutting blade 10 is located above the cutting table 14;

[0025] The setting of the limiting groove 13 can play a limiting role for the cutting blade 10, and the setting of the cutting table 14 can make the cutting blade 10 better cut the cling film when moving left and right;

[0026] Furthermore, a limiting sleeve 15 is installed on the top of the limiting slider 5, a return spring 16 is connected inside the limiting sleeve 15, a damper is arranged inside the return spring 16, a pressing rod 17 is connected to the top of the return spring 16, and the top of the pressing rod 17 is connected to the bottom of the transmission rod 6;
