A push plate 44 is fixedly installed on the top of the connecting rod 45, and the push plate 44 is flush with the bottom wall of the explosion hole 41.

[0034] The bottom of the connecting rod 45 is located inside the internal groove 47, a friction iron block 48 is fixedly installed at the bottom of the connecting rod 45, a flint 49 is fixedly installed on the inner wall of the internal groove 47, and the flint 49 fits on the outer wall of the friction iron block 48.

After filling, the sealing cover 31 can be sealed above the explosion hole 41 by screwing the mounting block 34 inside the explosion hole 41, and a fuse is set through the upper detonating tube 32 and the connecting hole 35 to ensure that the internal gunpowder is ignited, and through the setting of the sealing cover 31, it is ensured that the impact force generated by the gunpowder when it explodes will act on the push plate 44, thereby further ensuring the safety during the explosion; and before the explosion, the device body 1 is pre-inserted into the pre-prepared mounting hole. During insertion, the positioning ring 22 is used to ensure that the explosion hole 41 is located outside and the explosion hole 42 is located inside, and the rubber sleeve 21 fits inside the explosion hole to ensure a certain degree of sealing.

During explosion transmission, gunpowder is filled in both the explosion hole 42 and the explosion transmission hole 41. The impact force generated after the gunpowder in the explosion transmission hole 41 is ignited will act on the push plate 44. The push plate 44 moves downward under the push of the impact force, thereby driving the lower connecting rod 45 and the friction iron block 48 to move downward quickly. The friction iron block 48 moves downward quickly and generates friction with the flint 49, thereby generating sparks.
