Tunnel smooth blasting blast hole positioner device

The utility model discloses a smooth blasting blasthole positioner device, the device achieves the blasthole positioning effect through the action of a fixture and a positioning steel pipe, the blasthole positioning effect formed by adopting the device can replace the traditional mode of directly measuring the position of a blasthole on a tunnel face, and the traditional blasthole positioning mode has the defects of tedious measurement, high measurement accuracy, high measurement accuracy and the like. According to the principle of the device, a clamp and a positioning steel pipe are used for being fixed to a steel arch frame, punching is directly carried out through the positioning steel pipe, rapid positioning and accurate positioning are easy, the whole blast hole of an excavation size boundary line can be covered and controlled, and the smooth blasting blast hole positioner device can control the distance between peripheral holes and the angle of the peripheral holes. The tunnel blast hole positioning dev
