[0018] 1. In the present application, when in use, the measuring probe is attached to the gap, and the data after detection is reflected on the display screen. When the light intensity is not strong, the baffle is in a position perpendicular to the front of the detector body. When the light intensity becomes strong, the baffle is rotated to block the light according to the intensity angle of the light. First, the pressure plate is used to drive the baffles on both sides to move, and the movement of the baffle drives the plug column to move. The plug column moves away from the socket to cancel the fixation of the baffle.
