A card slot 14 is opened on the left side of the second sealing ring 9, and the inner cavity of the card slot 14 is slidably connected to the surface of the buckle 13. When the user pulls the rotating rod 12 to rotate upward, the buckle 13 is driven to disengage from the inside of the card slot 14, which makes it convenient for the staff to separate the outer tube 6 and the connecting tube 7. At the same time, when the outer tube 6 and the connecting tube 7 need to be connected, the outer tube 6 and the connecting tube 7 are placed on the same horizontal plane, and the rotating rod 12 is rotated to drive the buckle 13 to insert into the inside of the card slot 14, which makes it convenient for the user to quickly connect the outer tube 6 and the connecting tube 7. The operation is simple and convenient, which improves the work efficiency of the staff.

[0022] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment: a fixing rod 15 is fixedly connected to the right side of the top of the first sealing ring 8, a connecting rod 16 is slidably connected to the surface of the fixing rod 15, and an end of the connecting rod 16 away from the fixing rod 15 is fixedly connected to an abutment rod 17.

At the same time, when the outer tube 6 and the connecting tube 7 need to be connected, the outer tube 6 and the connecting tube 7 are placed on the same horizontal plane, and the rotating rod 12 is rotated to drive the buckle ring 13 to insert into the interior of the card slot 14, which makes it convenient for the user to quickly connect the outer tube 6 and the connecting tube 7. The operation is simple and convenient, which improves the work efficiency of the staff. By setting structures such as the fixing rod 15, the connecting rod 16, and the abutting rod 17, it is convenient for the staff to fix the rotating rod 12, which improves the stability of the device. A limit plate 18 is provided to prevent the user from applying too much force when pulling the connecting rod 16 to slide upward, causing the connecting rod 16 to separate from the surface of the fixing rod 15, thereby realizing position limitation of the connecting rod 16. By providing a tension spring 19, the position of the connecting rod 16 is effectively limited by the force of the tension spring 19 to prevent the device from shaking and affecting the fixing effect of the rotating rod 12. By providing an insulating layer 20, mineral wool can be used to effectively prevent heat loss, reduce system energy consumption, and further improve energy utilization efficiency.
