When the moving plate 12 descends to the middle position of the inner barrel, it stops, and a pair of first motors 7 are started to drive the transmission shaft 8 to rotate, and the transmission shaft 8 drives the gear 9. When the gear 9 rotates, it drives the hollow shaft 5 to move through a plurality of snap rings 6, so that the pair of moving plates 12 are close to each other. When the clamping plate 13 is close to the outer wall of the inner barrel, the inner barrel is pulled up by contracting the electric push rod 2, and the second motor 11 is started to drive the spline shaft 10 to rotate.
