Shallow-buried sensor probe nail

The utility model discloses a shallow-buried sensor probe nail, and belongs to the technical field of photoelectric communication. Comprising a middle shaft, a base, a skirt edge and a threaded protrusion. The probe nail adopts an integrated non-detachable rigid design, so that the transmission efficiency of vibration signal transmission is ensured; drilling of the percussion drill is matched with anchoring of an anchoring agent, rapid installation of the probe nail at any position of a tunnel is achieved, the construction time is greatly shortened, and the cyclic utilization rate and the working efficiency of the sensor are improved; a spherical bulge is designed at the lower end of the middle shaft and is coupled with rock and an anchoring agent in a hole, so that the probe nail is fastened in the direction perpendicular to the rock mass and is matched with the hole, and the vibration conduction effect is improved; due to the design of the oval inverted cone shape of the inverted cone clamping piece, the st
