When the connecting column 107 starts to move, the movable plate 104 starts to slide horizontally in the fixed block 102. Through the arc movement of the connecting column 107, multiple movable plates 104 also move toward the middle in the slide groove 103 respectively. As the staff continues to rotate the rotating plate 105, the multiple movable plates 104 gradually clamp the transmission shaft of the compressor firmly. At this time, the staff releases the slider 110. When rotating the rotating plate 105, the staff has been pulling the slider vertically. 110. When the slider 110 is released, the push plate 113 is affected by the elastic force of multiple springs 111 and begins to pop out in the direction of the rotating arm body 1.

When the rotating plate 105 starts to rotate forward, the notch 106 also rotates horizontally with the rotating plate 105. The notch 106 makes the connecting column 107 follow the notch 106 to move in an arc. When the connecting column 107 starts to move, the moving plate 104 starts to slide horizontally in the fixed block 102. Through the arc movement of the connecting column 107, multiple moving plates 104 also slide in the same direction.
