The left and right sides of the detection box 1 are equipped with moving wheels 14 through the adjusting device. In this embodiment, when in use, the sight is first manually placed in the detection box 1, and then the drive motor 9 is started. The output end of the drive motor 9 drives the gear 5 to rotate. During the rotation process, the gear 5 drives the rack 6 to move linearly along the tooth groove of the gear 5. The two groups of racks 6 move closer to the direction of the gear 5, and the rack 6 drives the support frame 10, and the support frame 10 drives the clamping block 7 until the V-shaped groove 11 contacts the outer wall of the sight, completing the clamping and fixing of the sight. Under the action of the spring 8, the clamping block 7 can play an auxiliary supporting role for the clamping block 7, ensuring that the clamping block 7 is stable for the sight, and the rubber pad 1 can increase the clamping area, thereby increasing the clamping force, making the clamping more firm, and not easy to loosen and deviate. Then, clean water is injected into the detection box 1 to perform airtightness detection on the sight.

[0026] In actual use, the movement of the rack 6 is further guided. In this embodiment, two groups of slide grooves 15 are symmetrically opened on the bottom wall of the detection box 1, and a slide bar 16 is installed on the bottom wall of the rack 6. The slide bar 16 is slidably connected to the slide groove 15. The rack 6 drives the slide bar 16 to slide in the slide groove 15 during the left and right movement, thereby guiding the movement of the rack 6 and preventing the rack 6 from deviating from the motion trajectory.

The moving wheels 14 are installed at both ends of the bottom wall of each group of the lifting plates 19. When it is necessary to move the position of the detection box 1, the knob is manually rotated, and the knob drives the threaded rod 18 to rotate. During the rotation process, the threaded rod 18 drives the lifting plate 19 to move toward the ground until the moving wheel 14 contacts the ground, and then the detection box 1 can be moved to the target position by the moving wheel 14 to complete the movement of the position of the detection box 1. After moving, the threaded rod 18 is rotated in the opposite direction to drive the lifting plate 19 to move up, so that the lifting plate 19 drives the moving wheel 14 to leave the ground, which is convenient for the support leg 2 to support and ensure the stability of the detection box 1.
