The third electric push rod 1103 is started, and the third electric push rod 1103 is extended and retracted to drive the movable plate 1104 to move. When the movable plate 1104 moves, the clamping seat 1102 is driven to move left and right through the movable rod 1105, so that the distance between the two groups of clamping seats 1102 can be adjusted, so as to facilitate clamping of both sides of the container.

[0045] Please refer to the attached figure in the instruction manual Figure 2 , Figure 3 and Figure 4, the fourth electric push rods 16 are installed at the four corners of the upper end of the outer side of the first explosion-proof enclosure 2, the tops of the four groups of fourth electric push rods 16 are connected to the second explosion-proof enclosure 17, and the two groups of clamping seats 1102 are connected to the second rubber pads on one side close to the center of the bottom rod 13. The second rubber pads are provided to increase the friction between the clamping seats 1102 and the two ends of the container, thereby making the container more firmly clamped, and at the same time, it is convenient to protect the two ends of the container, and try to avoid the situation of being clamped at the two ends of the container.

[0046] Working principle: When in use, first place the container to be inspected on the top of the support frame 806, then open the second electric push rod 802, the second electric push rod 802 extends to drive the adjustment plate 803 to move downward, the adjustment plate 803 moves downward and drives the arc pressure plate 805 to move downward through the adjustment member 804 until the two groups of arc pressure plates 805 are pressed on the top of the container, then open the third electric push rod 1103, when the third electric push rod 1103 works, it drives the movable plate 1104 to move toward the direction of the bracket 1101, when the movable plate 1104 moves, it drives the clamping seat 1102 to move toward the direction of the container through the movable rod 1105 until the two groups of clamping seats 1102 are clamped on both sides of the container, so that the device can clamp and fix containers of different specifications.

[0047] At this time, the first rubber pad and the second rubber pad are in direct contact with the container. The first rubber pad increases the friction between the arc pressure plate 805 and the top of the container and between the support frame 806 and the bottom of the container, so that the container is clamped more firmly, and the top and bottom of the container can be protected to avoid pinching at the top and bottom of the container as much as possible. Through the provision of the second rubber pad, the friction between the clamping seat 1102 and the two ends of the container is increased, so that the container is clamped more firmly, and it is also convenient to protect the two ends of the container to avoid pinching at the two ends of the container as much as possible.

Under the sliding cooperation of the groove 15 and the convex strip 10, the lifting plate 7 drives the connecting block 14 to move downward along the convex strip 10 during movement, thereby driving the container to move downward until the container is located inside the first explosion-proof enclosure 2. The container is protected by the first explosion-proof enclosure 2 to prevent the container from being damaged or exploded, which may endanger the staff, thereby greatly improving the protection and safety of the device. At the same time, the strength of the first explosion-proof enclosure 2 is improved through the mutual cooperation of the first reinforcement rib 401 and the second reinforcement rib 402, and the explosion-proof effect of the first explosion-proof enclosure 2 is further improved. At the same time, the fourth electric push rod 16 is controlled to contract and drive the second explosion-proof enclosure 17 to close, thereby being able to protect the container more comprehensively to prevent the container from being damaged or exploded, which may endanger the staff, thereby greatly improving the protection and safety of the device.
