Fixing device of micro-seismic sensor

The utility model relates to the technical field of sensor fixation, in particular to a microseismic sensor fixing device which comprises a sensor, a telescopic assembly arranged at the right end of the sensor, a fixing box arranged at the right end of the telescopic assembly, and a sliding assembly arranged in an inner cavity of the fixing box. The upper side and the lower side of the left end of the sliding assembly extend to the upper side and the lower side of the left end of the fixing box correspondingly and are fixedly provided with fixing plates correspondingly, and the telescopic assembly is sleeved with a spring. The fixing device of the micro-seismic sensor achieves the purpose of fixing the sensor, and solves the problems that the micro-seismic sensor is installed in a drill hole with the depth of about 2-3 meters, after the micro-seismic sensor is inserted into the drill hole, the micro-seismic sensor is fixed in the drill hole through resin or cement and the like, the micro-seismic sensor cannot
