The embodiment of the utility model discloses hole is multi -parameter detecting system relates to hole system and detects technical field for realize portably that the hole is the detection of diameter, circularity, axiality. This hole is multi -parameter detecting system includes laser emitter, installation component, laser receiving device and angle measuring device, laser receiving device passes through installation component telescopically locates treating in the inspection hole of measured workpiece, wherein laser receiving device can receive the laser of laser emitter transmission, angle measuring device can measure laser receiving device's turned angle. It can the inspection hole be diameter, circularity, the multiple parameter of axiality to adopt above -mentioned hole is multi -parameter detecting system, has realized that it is the parameter that a system just can detect multiple hole.
