Detection equipment and lifting adjusting device thereof

The invention relates to detection equipment and a lifting adjusting device thereof. The lifting adjusting device comprises a drive mechanism, a transmission mechanism, a supporting platform and a guiding mechanism. The drive mechanism comprises a rotationally-arranged rotary knob, and the rotary knob rotates and drives the transmission mechanism to run. The transmission mechanism comprises a leadscrew arranged in the height direction, wherein the lead screw is matched with the supporting platform. The guiding mechanism comprises a guide rail arranged in the height direction, and the supporting platform is in sliding fit with the guide rail. When the rotary knob rotates, the lead screw is driven to rotate, and the supporting platform is made to ascend and descend along the guide rail. Therotary knob rotates and drives the supporting platform to ascend and descend, precision can be guaranteed, meanwhile, stability is high, and the position cannot be lowered or elevated at will. The mechanism is simple, operati
