[0002] Seat belts are safety features used on equipment, such as aircraft, for safety during aerial work and performances. They are primarily made of polyester, polypropylene, and nylon. Seat belts are not just webbing; they are assembled from other components.

[0003] Seatbelts have become a primary concern for drivers and passengers, and one of the most important features of a car. Traditional components that ensure safe driving, such as rearview mirrors and left and right door mirrors (traditional rearview systems), seatbelts, airbags, and ABS (anti-lock braking systems), are familiar to drivers and passengers and are widely used in imported luxury cars.

[0004] During the production process of seat belts, the seat belts need to be cut into fixed lengths by a cutting device to facilitate subsequent installation of the seat belts.

[0005] During the operation of the specific embodiment, the inventors found the following defects:

[0006] However, the cutting device can only cut a single seat belt at a time, which reduces the working efficiency of the cutting device. Moreover, when the seat belt is not tightened when cutting, the length of the seat belt after cutting is likely to be long, requiring subsequent manual cutting of the seat belt.

[0007] It should be noted that the above content belongs to the technical knowledge scope of the inventor. Since the technical content in this field is vast and too complicated, the above content of this application does not necessarily constitute prior art. Utility Model Content
