In the process of disconnecting the above-mentioned storage limit block 21 and the storage plug-in slot 29, when there is no storage limit block 21 squeezing and limiting the storage plug-in slot 29, at the moment of separation, under the action of the spring 28 and the sliding plate 26, the movable plate 25 carries the braking tooth plate 30 through the active cavity 4 and is clamped together with the gear 1 7 and the gear 2 11. Subsequently, when the limiting limit block 20 enters the linkage groove 15, the end of the limiting limit block 20 will be clamped on the side of the movable plate 25, thereby achieving a limiting effect.
