[0034] Furthermore, the interval air supply mechanism 9 includes a fixed plate 97 fixedly installed on the bottom of the detection box 1, and an airbag 93 is fixedly connected to the surface of the fixed plate 97. The airbag 93 is connected to the telescopic bag 82 through a connecting tube 94, and a one-way valve is arranged inside the connecting tube 94. The surface of the fixed plate 97 is connected to a push plate 96 by setting an elastic mechanism. The airbag 93 is located between the push plate 96 and the fixed plate 97.
