When the clamping assembly is working, the docking rod 12 can be clamped with the fixing block 11, so that the cover plate 5 covers the connecting pipe 4;

[0038] The disassembly component is arranged inside the side connecting block 3, including a column 7 slidably arranged inside the side connecting block 3 and a pressure block 6 fixedly connected to the upper surface of the column 7. The disassembly component plays a role when the staff needs to remove the cover plate 5, and can push out the docking rod 12 and the cover plate 5 to facilitate the staff to take them away.

[0039] The locking assembly also includes a slot 13 opened on the side of the docking rod 12, and the slot 13 corresponds to the block 14 one by one, and the upper and lower sides of the block 14 are fixedly connected with sliders 15, and the surface of the slider 15 is fixedly connected with a second spring 16 that plays an elastic reset role, and the other side of the second spring 16 is fixedly connected to the inner wall of the fixed block 11.

[0040] When docking the cover plate 5, the docking rod 12 is inserted into the fixed block 11. At this time, the block 14 will be pushed by the docking rod 12, and the docking rod 12 drives the slider 15 to slide in the slide groove 17, so that the slider 15 squeezes the second spring 16 and continues to press down. The docking rod 12 will push the pressure block 6, so that the pressure block 6 drives the limit block 8 to descend. When the limit block 8 contacts the lower inner wall of the limit groove 9, the block 14 and the groove 13 are in the same horizontal direction. At this time, the block 14 enters the groove 13 under the action of the slider 15 and the second spring 16, and then the docking rod 12 and the cover plate 5 are engaged with the side block 3, which is convenient for the operation of the cover plate 5.

[0041] Embodiment 2: Different from Embodiment 1, the slider 15 is provided to limit the moving distance of the block 14, thereby ensuring stability. Figure 3 As shown:

[0046] When installing the docking rod 12, the pressure block 6 and the column 7 will be driven to move downward. At this time, the first spring 10 will be squeezed, and the limit block 8 will slide inside the limit groove 9. After the end of the clamping block 14 moves out of the clamping groove 13, the pressure block 6 loses the pressure of the docking rod 12. At this time, the pressure block 6 rises under the action of the column 7 and the first spring 10, and then the pressure block 6 can push the docking rod 12 and the cover plate 5, which is convenient for the staff to disassemble.
