[0038] The working principle of this utility model:

[0039] At the beginning, the two support plates 2 are in an inclined state, and the two sliding plates 71 are in the closest position. At this time, the middle conduit 1 is placed on the two support plates 2, and then the middle conduit 1 is moved to above the specified position by the moving wheel 8. Then, the screw 74 is rotated by the turntable 75, and the screw 74 drives the sliding plate 71 to slide along the adjustment cavity 31, and the two sliding plates 71 move away from each other. The sliding plate 71 drives the support plate 2 to rotate along the first rotation axis 41 through the adjustment rod 72 and the second rotation axis 73, so that the inclined support plate 2 is turned to the vertical direction, and the height of the middle conduit 1 is gradually reduced. When the support plate 2 is in the vertical direction, the middle conduit 1 falls onto the holding rack 93. Finally, the transport trolley is lifted up and passes through the top of the middle conduit 1.
