[0025] The fixed seat is provided with at least two clamping assemblies, one fixed clamping block and one sliding clamping block which can slide up and down through a half-threaded screw, and the at least two clamping assemblies cooperate with each other to clamp the whole motor. The rotating adjusting rod 32 is connected with the sliding clamping block 33, and the balance adjusting assembly 30 is used to adjust the up and down sliding of the sliding clamping block 33, so as to clamp the outer wall of the motor stator seat, so as to realize the contact or separation of the first and second clamping heads and the stator seat of the whole motor.

[0026] The adjusting handle is fixed on the rotating adjusting rod, the end of the rotating adjusting rod penetrates through the sliding clamping block, and then the end of the rotating adjusting rod is screwed on the fixed seat. In the embodiment, the rotating adjusting rod is a cup head bolt. The adjusting handle is connected with the sliding clamping block, and the balance adjusting assembly 30 is rotated forward and reversely to achieve the purpose of adjusting the up and down sliding of the sliding clamping block, so as to contact and separate the motor stator seat, achieve the purpose of fixing the whole motor, and obtain the relative position of the balancing mud on the dynamic balancing weight device.
