A Bailey piece sliding groove 1-41 is provided at the bottom of the top plate 1-4.

[0029] A through hole 1-21 is provided on the back plate 1-2. A rotating rod 4 is provided inside the through hole 1-21. A torsion spring 5 is provided on the outer periphery of the rotating rod 4. One end of the torsion spring 5 is fixedly connected to the outer periphery of the rotating rod 4, and the other end of the torsion spring 5 is fixedly connected to the inner wall of the through hole 1-21. A positioning block 6 is provided on the outer periphery of the rotating rod 4. A rotating handle 7 is provided on one end of the rotating rod 4. A circular hole 8 is provided at the junction of the side plate 1-1 and the bottom plate 1-3. The circular hole 8 is composed of two semicircles symmetrically arranged on the side plate 1-1 and the bottom plate 1-3. The circular hole 8 is concentric with the through hole 1-21 and communicates with the limiting groove 1-32. One end of the rotating rod 4 with the positioning block 6 is located inside the circular hole 8.

[0030] In actual operation, when storage and fixation are required, first place the bottom of the Bailey piece in the placement groove 3-1 on the Bailey piece placement seat 3, insert the top into the Bailey piece slide groove 1-41, and then push the Bailey piece towards the back plate 1-2 until the limiting rods 2-1 on both sides of the pulley 2 are engaged behind the positioning block 6. At this time, the Bailey piece placement seat 3 is fixed.

[0031] When it is necessary to remove the Bailey piece, the rotating rod 4 can be rotated, and the positioning block 6 will rotate with the rotating rod 4 until the limiting rod 2-1 is no longer blocked by the positioning block 6. At this time, the Bailey piece can be pulled, and the Bailey piece placement seat 3 will slide along the slide groove 1-31 with the Bailey piece.
