The cutting component 1 includes a shell 11, a rotating shaft 12 and two cutters 13. A first groove 111 is formed on the top of the shell 11. The rotating shaft 12 is arranged in the first groove 111. The first groove 111 includes a first side wall 111a and two oppositely arranged second side walls 111b. The two ends of the rotating shaft 12 are rotatably connected to the two second side walls 111b respectively. The protective film roll is used to be sleeved on the rotating shaft 12. An opening 111c is formed on the first side wall 111a. One of the cutters 13 is installed at the top of the opening 111c, and the other of the cutters 13 is telescopically installed at the bottom of the opening 111c. Specifically, the operator puts the protective film roll on the rotating shaft 12, and then extends the protective film on the protective film roll through the opening 111c. After stretching the protective film to the required length, the cutter 13 installed at the bottom of the opening 111c is raised to make the two cutters 13 close to each other. In this way, the two cutters 13 are close to each other and can cut the protective film. In this way, the operator can stick or wrap the protective film on the position of the car that is prone to scratches to protect the car. Through such a setting, there is no need to manually cut the protective film, which avoids the situation where the operator accidentally hurts himself or others, avoids safety hazards, and greatly improves work efficiency.
[0031] Furthermore, two spaced-apart limit members are sleeved on the rotating shaft, and the two limit members are respectively arranged on both sides of the protective film roll, so as to limit the sliding of the protective film roll on the rotating shaft along the length direction of the rotating shaft, thereby preventing the protective film from being damaged when stretching the protective film.
[0032] See also Figures 1 to 3 In one embodiment, the cutting component 1 further includes a driving motor 14, a cavity is formed inside the housing 11, the driving motor 14 is arranged in the cavity, a protruding hole is formed at the bottom of the opening 111c, the protruding shaft of the driving motor 14 is connected to the cutter 13 installed at the bottom of the opening 111c through the protruding hole, and the protruding shaft of the driving motor 14 can be extended or retracted to make the two cutters approach or move away from each other. Specifically, the operator puts the protective film roll on the rotating shaft 12, and then extends the protective film on the protective film roll and passes through the opening 111c. After the protective film is stretched to the required length, the operator starts the driving motor 14, and the protruding shaft of the driving motor 14 extends, which will drive the cutter 13 installed at the bottom of the opening 111c to move toward the cutter 13 installed at the top of the opening 111c, so that the two cutters 13 are close to each other, so that the protective film will be cut; through such a setting, the automatic extension or retraction of the cutter 13 can be achieved, which greatly reduces the labor intensity of the operator and improves the working efficiency.
[0033] See also Figure 1 and Figure 2 In one embodiment, the cutting device 100 includes a transport component 2, which includes a rotating motor, a shell 21, a conveyor belt component 22, a first transmission component 23 and a second transmission component 24.

The shell 21 is formed with a second groove 211, and the second groove 211 is formed with two oppositely arranged third side walls 211a. The first transmission component 23 is respectively rotatably connected to the two third side walls 211a, the output shaft of the rotating motor is connected to the first transmission component 23, and the second transmission component 24 is respectively rotatably connected to the two third side walls 211a. The first transmission component 23 and the second transmission component 24 are arranged at intervals, and the first transmission component 23 and the second transmission component 24 are transmission-connected through the conveyor belt component 22. Specifically, the operator puts the protective film roll on the rotating shaft 12, then extends the protective film on the protective film roll and passes through the opening 111c, and then adheres the front end of the protective film to the conveyor belt component 22. The operator starts the rotating motor, and the output shaft of the rotating motor rotates, which drives the first transmission component 23 to rotate, and the conveyor belt component 22 also runs synchronously. Since the front end of the protective film is adhered to the conveyor belt component 22, the protective film on the protective film roll will be stretched when the conveyor belt component 22 moves. When the protective film is stretched to the required length, the operator brings the two cutters 13 close to each other, so that the protective film can be cut off. Through such a setting, there is no need to stretch the protective film manually, and the automatic stretching of the protective film is realized, which further reduces the labor intensity of the operators.
