fifth step: when the rotation speed of the external motor is slowly changed into high speed, the rotation speed of the driving disc 5 is also slowly changed into high speed, the centrifugal force received by the brake block 44 is also continuously increased, the extrusion force between the extrusion rod 462 and the bulge 31 is also continuously increased, the continuously increased extrusion force can drive the extrusion rod 462 to tamper with the extrusion plate 463, the buffer spring 464 is continuously compressed at the moment, the cooling liquid in the first liquid cavity 461 and the second liquid cavity 466 is extruded through the extrusion plate 463, and the cooling liquid is sprayed onto the surface of the bulge 31 arranged on the inner side wall of the drum 3 through the nozzle 467, so that the effect of cooling is achieved on one end, close to the bulge 31, of the T-shaped brake tooth 452 when the T-shaped brake tooth 452 passes through, the abrasion loss caused by friction heat of the end of the T-shaped brake tooth 452 can be reduced, and the service life of the T-shaped brake tooth 452 is prolonged.
