[0025] The working principle of the present invention is as follows: when using the device, first pull the operating plate 67 to slide the operating plate 67 in the receiving groove 64, and at the same time make the operating plate 67 slide on the balance plate 69 to squeeze the special-shaped spring piece 68, so that the special-shaped spring piece 68 is in a compressed state, and at the same time make the operating plate 67 drive the limiting column 66 to retract into the receiving groove 64, then move the filter plate 610 to drive the mounting ring 62 to be inserted into the mounting groove 61, and then rotate the rotating plate 63 to rotate the rotating plate 63 to the filter plate 610, and then release the operating plate 67, so that the special-shaped spring piece 68 drives the limiting column 66 through the operating plate 67 to be inserted into the limiting hole 65; When the brushless torque motor body 3 is at a high temperature and needs to be cooled, the cooling fan 418 is first started to blow air to the cooling aluminum sheet 423 on the brushless torque motor body 3 to dissipate heat, and then the water pump 59 is started to pump water out of the water tank 58 and transport it to the water spray rack 56 through the water pipe 510 to be sprayed out from the spray head 57, spraying mist-like water droplets, so that the water droplets fall on the cooling aluminum sheet 423 to cool down, and cooperate with the cooling fan 418 to accelerate heat dissipation. At the same time, the vibration force of the brushless torque motor body 3 during movement squeezes the second spring 55, the elastic plate 54 and the telescopic rod 52 through the bottom plate 2, so that the second spring 55, the elastic plate 54 and the telescopic rod 52 are in a compressed state, so that the damper 53 reduces the reverse elastic force of the second spring 55 and the elastic plate 54; When the brushless torque motor body 3 is in a low temperature environment, the first motor 417 is first started, so that the output end of the first motor 417 drives one of the pulleys 416 to rotate, and at the same time, one of the pulleys 416 drives the other pulley 416 to rotate through the belt 415, and at the same time, the rotating shaft of the pulley 416 drives the reciprocating screw 42 to rotate in the reciprocating groove 41, and at the same time, the reciprocating screw 42 drives the reciprocating block 43 to move toward the brushless torque motor body 3, and at the same time, the reciprocating block 43 drives the rotating plate 46 and the guide plate 47 to move toward the bottom plate 2, so that the reciprocating screw 42 is reversely squeezed by the bottom plate 2 to drive the rotating plate 46 to rotate, and the rotating plate 46 drives the starting button 48 to squeeze the reciprocating block 43 and turn on the starting button 48, so that the starting button 48 controls the heating rod 45 to heat the brushless torque motor body 3 , so that the insulation plate 44 has the effect of keeping the heating rod 45 warm. When the reciprocating block 43 moves toward the bottom plate 2, the reciprocating block 43 drives the movable plate 49 to slide in the slide groove 410 under the action of the fixed ring 414 through the connecting rope 413. At the same time, the movable plate 49 slides on the balance bar 411 to squeeze the first spring 412, so that the first spring 412 is in a compressed state. At the same time, the movable plate 49 drives the cooling fan 418 away from the brushless torque motor body 3, and at the same time reduces or turns off the cooling fan 418, which can be determined according to the temperature environment of the brushless torque motor body 3. At the same time, the movable plate 49 drives the cleaning brush 420 to clean the heat dissipating aluminum sheet 423 through the extension plate 419, and at the same time, the extension plate 419 drives the limit block 421 to slide in the limit groove 422, and finally turns off the first motor 417.
