The invention discloses an omnidirectional cataclastic rock mass deep hole installation and recovery device of a microseismic unidirectional sensor. The omnidirectional cataclastic rock mass deep hole installation and recovery device comprises a sleeve which is embedded in a rock mass drilling hole, wherein a unidirectional sensor fixing device is installed at each part with a preset depth and direction in the sleeve and comprises an intermediate joint which is connected with the sleeve by inner threads, a wedge body combining body which is connected with the intermediate joint and is provided with a wedge body combining body female groove, a wedge body which is adapted to the wedge body combining body female groove, another unidirectional sensor which is connected with the wedge body, a tensile-resisting cable which is connected with the another unidirectional sensor, an elastic pressing device which is fixed on the wedge body combining body, and a pulling type lifting device which is connected with a second leading-out terminal of a cylindrical helical torsional spring of the elastic pressing device and is used for releasing the wedge body, wherein one end of the elastic pressing device tightly presses the wedge body in the wedge body combining body female groove. With the adoption of the omnidirectional cataclastic rock mass deep hole installation and recovery device, the installation is not limited by severe geological conditions and drilling inclined angles, the installation of a vertical hole and an inclined hole in a cataclastic rock mass can be realized, and the unidirectional sensors are easy to recover.
