The aperture detection device for house construction supervision drives the connecting rod to rotate by turning a knob, thereby driving the first bevel gear to rotate, and then driving the second bevel gear and the third bevel gear to rotate, and at the same time, the first screw and the second screw also rotate accordingly. When the first screw and the second screw rotate, the first slider and the second slider will move left and right on the first screw and the second screw, and the first measuring rod and the second measuring rod will also move accordingly. According to the depth of the hole, the sleeve rod is moved, so that the measuring depth can be increased, which is suitable for holes of different depths and the practicality of the detection device is increased.
