Background

In the process of processing initiating explosive devices, the locking notch is an important processing procedure of the fire detonator, and when the fire detonator is combined with the fuse, the fuse is usually placed into a cavity of the fire detonator and then is clamped by using a detonator clamp. As the clamping position of the detonator clamp can not be forcibly controlled, once the clamping position is improper, accidents are easily caused.

If the fuse is too short and the bending degree is not enough, the flame of the fire-pulling tube can directly ignite the detonator, thereby causing accidents. If the sealing is not tight during water surface or underwater blasting, water can enter the detonator cavity, and the blasting fuse can not detonate the blasting cap to form a 'dummy gun'.
