Among them, the imaging unit 24 is a CCD camera.

[0027] It should be noted that the first driving member 22 and the second driving member 25 have the same structure. The first driving member 22 includes a first threaded rod and a first motor. The first threaded rod is rotatably provided on the inner top of the detection chamber 10. The mounting seat 21 is in threaded rotational connection with the first threaded rod.

In this specific embodiment, the telescopic member 32 is an electric push rod. Of course, in other embodiments, the telescopic member 32 can also be a pneumatic cylinder or a hydraulic cylinder.

[0030] On the basis of the above solution, in order to improve the support strength of the placement plate 31, specifically, the loading platform 3 further includes two telescopic plates 33.
