The invention can control the stroke of the delivery device C3 through the delivery stroke control device C4, so that the supporting plate C21 of the delivery device C2 can push the bagged tissues Z out of the case A from the delivery port A1 completely; the invention can also control the stroke of the delivery device C3 through the delivery stroke control device C4, so that the abutting plate C21 of the delivery device C2 can push the bagged tissues Z out of the case A from the delivery port A1, and one part of the bagged tissues Z is positioned outside the case A, and the other part of the bagged tissues Z is positioned in the case A, thereby avoiding the phenomenon that the bagged tissues Z fall off because a user does not take the bagged tissues Z in time. As shown in fig. 6, the front end of the pushing-out section C6112 is closed, so that the interlocking block C63 can be prevented from being pulled out of the interlocking guide slot C611 forward, and the lifting baffle C5 can be prevented from being lifted by people due to the interlocking block C63 being pulled out of the interlocking guide slot C611. In addition, the pushing-out section C6112 of the linkage guide groove C611 is arranged in parallel in the front-back direction, so that when the linkage block C63 moves in the pushing-out section C6112, the lifting baffle C5 cannot lift, the lifting stroke of the lifting baffle C5 is reduced, and the reduction of the space occupation of the lifting baffle C5 is facilitated. The linkage block C63 can be rotatably connected with the linkage seat C62, so that the linkage block C63 can be prevented from being stuck in the linkage guide groove C611.
