[0029] The adjusting rod 5 penetrates through the inside of the air duct lifting frame 2 and extends to the outside. The adjusting rod 5 can slide up and down along the inside of the air duct lifting frame 2. The top end of the traction spring 6 is connected to the bottom end of the air duct lifting frame 2, and the bottom end of the traction spring 6 is connected to the bottom end outside the adjusting rod 5.

[0030] Specifically, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, lift the air duct pressing plate 3 upward.

[0035] Working principle: When the utility model is in use, first, the air duct lifting frame 2 is lowered to the top of the bottom bearing frame 1. Then, the air duct pressing plate 3 is rotated to release the space at the top of the air duct lifting frame 2. Then, the air ducts are stacked on the top of the air duct lifting frame 2. According to the height of the air ducts, the air duct pressing plate 3 is lifted upward, the adjusting rod 5 slides upward, and the traction spring 6 is compressed under force. Then, the air duct pressing plate 3 is rotated to be above the air ducts, and the air duct pressing plate 3 is released. The traction spring 6 extends and resets, pulling the air duct pressing plate 3 downward, and the rubber positioning strip 4 is pressed on the surface of the air duct. The bottom of the rubber positioning strip 4 has concave and convex notches, which can match the circular pipe and increase the friction force of the contact surface at the same time. The four air duct pressing plates 3 can stably fix the position of the air duct. Then, the winch 7 is started, and the winch 7 winds up the traction cable 12. The traction cable 12 moves along the first guide wheel set 8, the second guide wheel set 9, the third guide wheel set 10, and the fourth guide wheel set 11 to lift the air duct lifting frame 2 and raise it, which is convenient for the staff to install.

The electric cylinder 18 in the inner cavity 17 is started, and the electric cylinder 18 extends or retracts, which can drive the extension rod 15 to slide up and down along the inside of the fixed cylinder 13, and the height of the extension rod 15 will change accordingly, which can adapt to indoor environments and installation requirements of various heights. During the idle stage, the air duct lifting frame 2 is lowered to the surface of the bottom bearing frame 1 and the traction cable 12 is untied and removed. Then, the electric cylinder 18 is retracted to the shortest state, and the fixed locking pins 22 are pulled out one by one. As the fixed locking pins 22 are pulled out, the fixed cylinder 13 that loses its restriction can be overturned with the bearing seat 19 and the connecting shaft 21 as the hinge points, and the overall volume of the equipment will be greatly reduced, which is convenient for handling and storage.
