The automatic cutting machine is used in the garment cutting process, and the computer-aided design setting data is used to control the movement direction of the cutter to produce the required pieces.

[0003] In this type of cutting bed equipment, in order to ensure life safety, emergency stop buttons and safety gratings are generally set for double protection. For example, the Chinese utility model patent No. 202321641730.0 (authorization announcement CN220149939U) discloses a cutting bed with a safety grating device. However, this type of equipment still has certain hidden dangers. This type of equipment usually sets the control buttons and emergency stop buttons used to control the operation of the machine on the outer enclosure of the frame, and the height of the outer enclosure of the frame is generally not very high, which causes people to bow their heads and bend over when operating the buttons and emergency stop buttons. Especially in an emergency, when the emergency stop button needs to be activated, the action will not be so quick and timely, and when bending over or squatting to operate the button, it is easy to hit the machine and cause danger. In addition, some models will also set the emergency stop button on the body and in the middle of the two pillars of the safety grating. When bending over to operate, it will also collide with the machine moving back and forth on the workbench and cause danger.
