In a natural state, the rotating block is suspended on the connecting pin through the rotating groove, and the lower part of the vertical portion is in a driving groove of a driving plate, and the inclined portion can contact the edge of a driving plate; when the driving plate moves from the vertical portion to the direction of the inclined portion, the driving plate contacts the vertical portion through the driving groove to push the collision block to move, and a driving structure for driving the rotating block to rotate upward is connected to the bracket.

[0005] In the present invention, the frame of the bending machine to be assembled is placed on a set of power components, that is, placed on the upper side of the frames of two transport vehicles. When the frame of the bending machine to be assembled needs to be transported, the driving structure 2 does not perform any action, the rotating block 1 is in a natural state, the guide rail seat slides along the supporting rail, the guide rail seat drives the driving plate to move, and the sliding direction of the guide rail seat is controlled to make the driving plate move from the vertical part 1 toward the direction of the inclined part 1. When the driving plate contacts the vertical part 1, the driving plate pushes the collision block 1 to move, and the collision block 1 drives the frame to move along the fixed rail.
