Detonator blasting device

The invention belongs to the technical field of blasting, and particularly relates to a detonator blasting device. Comprising an extension mechanism and a clamping mechanism; the extension mechanism is composed of a plurality of multi-stage telescopic rods; the clamping mechanism is composed of a clamping ring and a pull rod, the clamping ring is nested in the first interval, and the clamping ring makes contact with the portion, close to the first interval, of the telescopic rod; a pull rod is arranged on the face, close to the first ring, of the clamping ring and penetrates through the first ring, and a detonator is clamped in the middle of the clamping ring. By pulling the pull rod, the clamping ring slides on the inner wall of the telescopic rod, a detonator can be conveniently taken out, and in the process, the situation that the detonator touches the hole wall, consequently, a blast hole collapses, and secondary filling is affected is effectively avoided; and collapse of blast holes is avoided, so that s
