The top of the bottom plate 16 is provided with a placement groove 17, and the top of the placement groove 17 is fixedly installed with a rubber pad 18; One end of the first rotating shaft 5 is fixedly connected to the first gear 19, and one end of the second rotating shaft 15 is fixedly connected to the second gear 20. A transmission shaft 21 is rotatably connected to the side of the device body 1 away from the display screen 2. A transmission disk 22 is rotatably connected to the transmission shaft 21, and a symmetrically arranged extrusion shaft 23 is fixedly connected to the transmission disk 22. A transmission plate 24 is sleeved on the extrusion shaft 23, and an extrusion groove 25 is opened on the transmission plate 24. The top ends of the two transmission plates 24 on the side away from each other are fixedly connected to the first rack 26, and the bottom ends of the two transmission plates 24 on the side away from each other are fixedly connected to the second rack 27.

[0018] Specifically, a rotating disk 30 is fixedly connected to the top of the worm 29 . The rotating disk 30 is designed as an anti-skid structure, so that the worm 29 can be rotated by the rotating disk 30 , so that the worm 29 can transmit the power to the worm wheel 28 .
[0019] Specifically, the outer side of the limiting ring 7 is designed as an arc structure, one side of the extrusion block 10 is designed as an arc structure, the extrusion spring 14 is an annular spring, the extrusion spring 14 is sleeved in the arc pit, the extrusion spring 14 and the extrusion block 10 are arranged correspondingly, and the arc structure design facilitates the extrusion spring 14 to be firmly sleeved on the outer side of the limiting ring 7, and at the same time, the extrusion block 10 is evenly squeezed.
[0020] Specifically, the placement groove 17 is designed as a semicircular structure, and the rubber pad 18 is designed as a semicircular structure, which is convenient for supporting the bottom ends of the safety bottle and the bubble absorption bottle to avoid friction and collision.
