Before the bottom of the sound insulation cover 2 is inserted into the annular groove 11, the two sides of its bottom will contact the curved ends of the blocking block 13, so that the blocking block 13 slides in the force box slide groove cylinder 14 and squeezes the spring 16. When the bottom of the sound insulation cover 2 completely enters the annular groove 11, the slot 12 facilitates the alignment of the blocking block 13, and then under the elastic force of the spring 16, the blocking block 13 is driven to reset, causing the blocking block 13 to be inserted into the slot 12, and its bottom fits against the inner wall of the slot 12, which has a limiting effect on the sound insulation cover 2 as a whole.

Before the bottom of the sound insulation cover 2 is inserted into the annular groove 11, the two sides of its bottom will contact the curved end of the block block 13, so that the block block 13 slides in the slide groove cylinder 14 of the force box and squeezes the spring 16. Then, when the bottom of the sound insulation cover 2 completely enters the annular groove 11, the slot 12 is convenient for the block block 13 to be aligned, and then under the elastic force of the spring 16, the block block 13 is driven to reset, so that the block block 13 is inserted into the slot 12, and its bottom is close to the inner wall of the slot 12. The soundproof cover 2 is closed, which has a limiting effect on the whole. By turning the knob on the top of the threaded rod 6, the threaded rod 6 itself rotates, so that the movable ring 3 slides upward on the outer wall of the soundproof cover 2, and then the connecting rods 7 on both sides rotate, causing the bottom of the connecting rod 7 and the sliding rod 8 to extend into the soundproof cover 2 until the clamping plates 9 on both sides clamp the motor and the rubber pads 10 remain in contact with the outer wall of the motor. In this way, the motor can be stabilized, the amplitude of vibration can be reduced, and the noise during the operation of the motor can be reduced. By pulling the pulling frames 15 on both sides, the blocking block 13 can slide back into the slide groove cylinder 14, and the limiting effect on the soundproof cover 2 can be released.
