A threaded rod 206 is fixedly connected to the output shaft of the drive motor 203, and the threaded rod 206 is rotatably connected to the lower fixing plate 202. A limiting groove 205 is formed on the surface of the support plate 201, and multiple sets of threaded blocks 204 are slidably connected inside the limiting groove 205, which has a limiting function. All sets of threaded blocks 204 are threadedly connected to the threaded rod 206, and the upper surface of all sets of threaded blocks 204 are fixedly connected to the threaded rod 206. A clamping seat 207 is attached, and the lower surface of the clamping seat 207 is slidably connected to the support plate 201. A clamping seat 208 is provided on one side of each clamping seat 207, and the clamping seat 208 is fixedly connected to the support plate 201. An auxiliary plate 209 and an auxiliary plate 210 are provided on the upper side of each clamping seat 207 and clamping seat 208. Two sets of support frames 211 are fixedly connected to the upper surface of the support plate 201, and a lifting assembly 212 is provided between the support frames 211. The threaded rod 206 is rotated by the drive motor 203, thereby allowing the multiple clamping seats 207 and clamping seats 208 to simultaneously clamp and fix the dispensing bottles.

[0031] The lifting assembly 212 includes two sets of electric push rods 212a fixedly connected to the main unit housing 101. The output shafts of the electric push rods 212a are all fixedly connected to lifting plates 212b. Two sets of connecting rods 212c are fixedly connected between the two sets of lifting plates 212b.

[0036] During use, based on the height of the dispensing bottle, the electric push rod 212a is activated by power to push the lifting plate 212b upward on the surface of the limiting rod 212d. The connecting rod 212c, which is fixedly connected to the lifting plate 212b, drives the auxiliary plate 1 209 and the auxiliary plate 210 upward, so that the auxiliary plate 1 209 and the auxiliary plate 210 move upward synchronously to the designated position on the surface of the fixed rod 213. Then, the dispensing bottle is placed between the clamping seat 1 207 and the clamping seat 208. Then, the drive motor 203 is activated by power to drive the threaded rod 206 to rotate. The threaded block 204, which is threadedly connected to the threaded rod 206, slides in a limited position on the inner wall surface of the limiting groove 205, so that the clamping seat 1 207, which is fixedly connected to the threaded block 204, moves towards the clamping seat 208 to clamp the dispensing bottle. At the same time, the fixed rod 213, which is fixedly connected to the clamping seat 1 207, drives the auxiliary plate 1 209 to move synchronously towards the auxiliary plate 210 to fix the dispensing bottle.
