The fixing member acts on the flange and fixes the ring piece. The fixing tube 8 cannot withdraw from the flange hole, driving the turntable 5 to rotate. The rotation angle range is between ninety-five degrees and one hundred and twenty degrees. This will not hinder the lifting of the second ring piece. Preferably, the rotation angle of the turntable 5 is one hundred degrees, driving the first ring piece to rotate together to move away from the four rolling supports.

The third ring piece is hoisted and Place it horizontally in the upper opening, fix the third ring piece with the first ring piece and the second ring piece respectively, and finally drive the turntable 5 to continue to rotate 180 degrees. The previous lower opening is now facing upwards, and the fourth ring piece is lifted by the lifting equipment and placed horizontally in this opening.

Conversely, when the forward and reverse screws 14 are reversed, the two sliders 13 are synchronously slid in the opposite directions due to the action of the forward and reverse threads until they both tend to the horizontal direction, thereby driving the movable plate 4 to move downward, so as to realize driving the movable plate 4 to move up and down.

[0035] like Figure 6 As shown, in some embodiments, the fixing member includes a driving block 16 slidably arranged in the fixing cylinder 8, the driving block 16 slides in the horizontal direction, a fixing block 17 is arranged in the fixing cylinder 8, the fixing block 17 is fixed in the fixing cylinder 8, a threaded rod 18 with a thread penetrating the driving block 16 is rotatably arranged in the fixing cylinder 8, the threaded rod 18 is in the horizontal direction, a driving rod 19 is hinged on the driving block 16, a limiting rod 20 is hinged on the fixing block 17, the limiting rod 20 is overlapped with the flange and the free end is hinged to the driving rod 19, and a strip groove for the driving rod 19 and the limiting rod 20 to pass through is constructed on the fixing cylinder 8;

[0036] Referring to the above, in the initial state, the driving block 16 is away from the fixed block 17, and the driving rod 19 and the limiting rod 20 are both completely retracted into the fixed cylinder 8.

On the contrary, the threaded rod 18 is driven to reverse, and the driving block 16 slides away from the fixed block 17 due to the action of the thread. In this process, the driving rod 19 rotates around the hinge point and is retracted into the fixed cylinder 8.
