The bearing holes of the parallel swing rods for connecting with the fixed column of the middle shaft are the same in size and are all positioned on the central movement pivot of each parallel swing rod. The sizes of the shaft holes on the left and right movable frames are the same, the radiuses of the shaft holes connected with the parallel swing rods are the same, and the distances from the middle shaft hole point of the parallel swing rods to the left and right sides and the connecting holes of the movable frames are the same. The shapes of the upper, middle and lower parallel swing rods are the same, and the parameter values are completely the same.

The external connected reinforced non-independent suspension mechanism has similar left and right movable frames, which are placed in left and right directions and cannot be mixed and used, and all parameters such as shaft hole and length are the same.
