This utility model belongs to the field of punching equipment, specifically relating to a precision punching equipment for backpack shoulder straps. It includes a base plate, a support plate fixedly connected to the lower end of the base plate, a limiting mechanism on the support plate, and a bracket fixedly connected to the upper end of the base plate. A flattening mechanism is mounted on the bracket, and a punch is mounted on the flattening mechanism. This utility model uses a motor to drive a bidirectional screw to rotate and a top plate to perform a threaded movement. This causes a spring to elastically act on a sliding plate, allowing the clamping plate to move and clamp and limit backpack shoulder straps of different widths, ensuring precise strap positioning. Simultaneously, it avoids excessive clamping force that could deform the shoulder straps and affect processing accuracy.
