When the first permanent magnet block (14) rotates, it will drive the second permanent magnet block (42) to rotate. The second permanent magnet block (42) drives the second groove plate (41) to rotate through the built-in column (44). The built-in column (44) rotates inside the shaft rotation hole (53) through the ball bearing (45). Through the rotation of the second groove plate (41) and the second permanent magnet block (42), the medicine bottle (3) is driven to rotate. Step 2: When transporting the medicine bottle (3), to prevent the second groove plate (41) from rotating due to vibration, the elastic force of the spring (64) pushes the movable piece (61) downward, the telescopic component (7) is in the extended state, and the thrust of the movable piece (61) makes the rubber pad (62) stick tightly to the striped groove (54), the rubber pad (62) deforms, and part of it will enter the interior of the annular block (52); Step 3: When the limit on the passive rotating component (4) is released, after the second permanent magnet block (42) is aligned with the first permanent magnet block (14), the column plate (75) will also be magnetically attracted to the first permanent magnet block (14). The column plate (75) moves upward through the magnetic attraction force. The movement of the column plate (75) drives the extension column (77) to move upward. The column plate (75) slides inside the cylinder shell (71). The extension column (77) will drive the movable plate (61) to move upward. The magnetic attraction force between the multiple column plates (75) and the first permanent magnet block (14) is twice the elastic force of the spring (64). At this time, the movable plate (61) drives the rubber pad (62) to move upward. Step 4: To prevent the passive rotating component (4) from vibrating due to contact limit, causing the medicine bottle (3) to shift, when the column plate (75) and extension column (77) move upward, air will enter the silicone duckbill valve (73) and the interior of the cylinder shell (71) through the circulation hole (74). The circulation hole (74) restricts the flow of the gas entering, thereby controlling the speed at which the column plate (75) moves upward.
