When moving down, the tension spring 53 is stretched and elongated. When the rotating plate 55 contacts the cap on the lower side, it is pressed into the rotating opening 54 and extends into the rotating opening 54 until the moving plate 17 stops moving downward, and the tightened first torsion spring 56 drives the rotation. The plate 55 resets and snaps to the bottom of the cap.

Then, the main motor 51 starts to drive the drive shaft 33 to reverse, thereby driving the reel 28 to reverse and move to the left. The reel 28 reverses and closes the connecting wire 71 to drive the permanent magnet 26 to move upward until the cap adsorbed by the permanent magnet 26 moves to send out In the cavity 16, the drive shaft 33 continues to reverse due to the pressure of the clamping plate 60 and can no longer drive the clutch gear 38 to reverse, and when the wire pulley 28 moves to the left, the lower moving rod 43 pushes the moving gear 72 to the left to engage the moving gear 72. Connected to the standby gear 32 and the gear 48, the drive shaft 33 rotates in reverse through the engagement of the standby gear 32, the moving gear 72 and the gear 48 to drive the second shaft 46 to rotate, and the second shaft 46 rotates through the incomplete gear 47 and the inner cavity 73. The meshing of the inner wall on one side drives the push plate 70 to move to the right, that is, drives the push rod 44 to move to the right to drive the cap to move to the right limit position, which is convenient for manual retrieval, and then the second shaft 46 continues to rotate and passes through the incomplete gear 47. The engagement with the inner wall on the other side of the inner cavity 73 drives the push plate 70 to move to the left, that is, drives the push rod 44 to move to the left limit position, and finally, the main motor 51 stops running.

The above are only specific embodiments of the invention, but the protection scope of the invention is not limited to this, and any changes or substitutions that are not conceived of without creative work should be included within the protection scope of the invention. Therefore, the protection scope of the invention should be subject to the protection scope defined by the claims.
