The shape of the placement table 31 is adapted to the shape of the first through hole 3. The top of the placement table 31 is provided with a guard rail 5 along its edge direction. The detected object cannot cross the protective fence 5, and meanwhile, the detected object is always positioned on the placing table 31, so that the detected object is ensured to move along with the placing table 31.

The front of the test box body 1 is provided with a channel 2. The inside of the first through hole 3 communicates with the inside of the passage 2. One end of the channel 2 is located below the working chamber 11 and is provided with a movable door 21. The movable door 21 is provided with an observation window 211.

The test box body 1 is also internally provided with a moving component 4, and the moving component 4 drives the placing table 31 to move along the channel 2 to a position close to the movable door 21.

The first placing groove 42 is formed in the front face of the test box body 1. One end of the first placing groove 42 is provided with a protective door 421. The first placing groove 42 is disposed obliquely. The movement assembly 4 comprises a motor 41. The motor 41 is disposed at the bottom of the inner wall of the first placement groove 42. The output of the motor 41 is provided with a rotating disc 43. One side of the rotating disc 43 is provided with a screw rod 44, the top of the inner wall of the first placing groove 42 is provided with a first fixing rod 45, one end of the first fixing rod 45 extends into the screw rod 44, and the screw rod 44 is rotationally connected with the first fixing rod 45. The screw 44 is also inclined as a whole.

A second through hole 47 is formed on one side of the inner wall of the first placing groove 42, and the second through hole 47 is communicated with the inside of the channel 2. Screw block 46 is screwed on the outer peripheral surface of screw 44. The screw 46 passes through the second through hole 47, and the screw 46 is slidably connected to the second through hole 47.

The bottom of the placing table 31 is provided with a fixed block 48, and one end of the screw block 46 positioned in the channel 2 is attached to one side of the fixed block 48.
