[0006] When assembling the present invention, the sleeve is sleeved on the cross bar, and then the cross end of the cross bar is inserted into the socket of the connection box. During the insertion process, the plane of the cross end is made to correspond to the position of the middle piece. After the connection is completed, the plug-in block of the end frame is inserted into the inner opening of the connection box so that it enters the bottom cavity. After the preliminary assembly is completed, the cross bar is rotated 180 degrees, and the arcuate surface of the cross bar squeezes the middle piece to make it fall, and the middle piece drives the lifting piece to fall. The sleeve groove of the lifting piece is sleeved on the sleeve part of the plug-in block to achieve fixation. At this time, the plug-in block is locked inside the connection box, and then the filling block is inserted into the filling port from the filling port.

During assembly, the sleeve is sleeved on the cross bar, and then the cross end of the cross bar is inserted into the socket of the connection box. During the insertion process, the plane of the cross end corresponds to the position of the middle piece. After the connection is completed, the plug-in block of the end frame is inserted into the inner opening of the connection box so that it enters the bottom cavity. After the initial assembly is completed, the cross bar is rotated 180 degrees, and the curved surface of the cross bar squeezes the middle piece to make it descend, and the middle piece drives the lifting piece to descend. The sleeve groove of the lifting piece is sleeved on the sleeve part of the plug-in block to achieve fixation. At this time, the plug-in block is locked inside the connection box, and then the filling block is inserted into the filling port from the filling port. The connection box and the cross bar are locked and connected by the filling block to achieve the fixation of the assembly position. The device is installed by plugging, and then the internal locking is completed by the rotary locking mechanism to achieve the overall connection fixation, reducing the difficulty of loading and unloading.
