When the retractable rod 312 retracts until contacting the first switch 42, the retractable rod 312 starts to extend to drive the piston plate 32 to slide in the temporary liquid storage tank 11, the piston plate 32 pushes the liquid out of the temporary liquid storage tank 11 to the discharge pipe 13, and the liquid flows out of the discharge pipe 13 to the filling bottles below the discharge port 132.

When the volume of the liquid flowing out of the discharging pipe 13 at a single time needs to be adjusted, an operator rotates the hand wheel 17 to drive the second bevel gear 63 to rotate, the second bevel gear 63 rotates to drive the first bevel gear 62 to rotate, the first bevel gear 62 rotates to drive the fourth connecting rod 15 to rotate, the fourth connecting rod 15 rotates to drive the second gear 61 to rotate, the second gear 61 rotates to drive the first gear 52 to rotate, the first gear 52 rotates to move up and down along the lines of the threads, the first gear 52 moves up and down to drive the connecting sleeve 54 and the second connecting rod 53 to move up and down, the second connecting rod 53 moves up and down to drive the second switch 43 to move up and down, and the first switch 42 is always fixedly connected to the cylinder body 311, so that the distance between the first switch 42 and the second switch 43 changes, the sliding distance of the piston plate 32 changes, and the volume flowing out of the discharging pipe 13.

When the height dimension of filling bottle diminishes, earlier with bolt 91 to the direction removal of keeping away from spacing dish 92, make bolt 91 afterbody extract spacing hole 921, rotation handle 823 drives third gear 82 and rotates, third gear 82 rotates and drives rack 81 and rises, rack 81 rises and drives connecting block 7 along recess 73 length direction and rise, connecting block 7 rises and makes and place platform 71 and rise, thereby the distance that makes between placing platform 71 and discharge gate 132 diminishes, make the distance between filling bottle and the discharge gate 132 shorten. Then pass the bolt 91 again and pass the second connecting hole on the handle 823 back with spacing hole 921 grafting cooperation, compression spring 931 exerts the elastic force who is close to spacing dish 92 direction to propping tight piece 932, make the bolt 91 afterbody prop tightly in spacing hole 921 can.

When the height dimension grow of filling bottle, earlier with bolt 91 to the direction removal of keeping away from spacing dish 92, make bolt 91 afterbody extract spacing hole 921, rotate handle 823 again and drive third gear 82 and rotate, third gear 82 rotates and drives rack 81 and descend, rack 81 descends and drives connecting block 7 along recess 73 length direction decline, and connecting block 7 descends and makes and place platform 71 decline, makes the distance grow between placing platform 71 and discharge gate 132. Then pass the bolt 91 again and pass the second connecting hole on the handle 823 back with spacing hole 921 grafting cooperation, compression spring 931 exerts the elastic force who is close to spacing dish 92 direction to propping tight piece 932, make the bolt 91 afterbody prop tightly in spacing hole 921 can.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
