The device mainly comprises an inner drum, an outer drum, an inner tooth friction plate, an outer tooth friction plate, a pressing plate, a spring pin, a compression wheel disc and a separating device. The outer tooth friction plates and the inner tooth friction plates are alternately sleeved on the inner drum, and teeth on the inner tooth friction plates are respectively meshed with tooth grooves of the inner drum and the outer drum. The full set of friction plates is between the inner drum flange and the pressure plate. One end of the spring pin is screwed on the pressing plate and is riveted, and the other end of the spring pin is connected with the compression wheel disc. The spring is sleeved on the spring pin and supported between the inner drum and the compression wheel disc, and the tension of the spring enables the pressure plate to press the friction plate. In the assembling process, if the external tooth friction plates are not completely aligned in the circumferential direction and the height direction, the external tooth friction plates are not concentric in the circumferential direction and are not aligned in the height direction, so that the external drum installed in a matched mode with the external tooth friction plates cannot be installed continuously, and assembling failure is caused.
