The whole process can be completed by one staff member, and no complicated power device is required, which is easy to operate.

[0013] 3. The three-eye connecting plate of the utility model can be a triangular plate. When the two connecting holes corresponding to the pull rod connecting seat II are connected, the triangular plate is balanced in force and has a stable structure. When the staff releases the operation of any connecting hole of the pull rod connecting seat II, the triangular shape of the three-eye connecting plate ensures that the angle of the springboard is switched smoothly, which is convenient for passing loads.

[0014] 4. The pull rod of the utility model is made of welded H-shaped steel, I-shaped steel or round steel, which has a stronger load-bearing capacity and makes the overall structure more stable. BRIEF DESCRIPTION OF THE DRAWINGS
