The support base is arranged horizontally, the transfer positioning component is installed at the bottom of the support base, and the supporting lifting component is installed at the top of the support base. The limiting groove is formed at the bottom of the support base, which is recessed into the interior of the support base and is adapted to the shape of the transfer positioning component. The transfer positioning component is limited by the limiting groove. The limiting ridge is formed at the bottom of the support base, which forms an angle with the limiting groove and protrudes below the support base. The transfer positioning component is limited by the limiting ridge.

[0044] The transfer positioning assembly includes a fixed support plate 210 and a movable support plate 220. The fixed support plate is located below the support base, and its middle portion is embedded in the limiting groove. Its two ends are exposed from the outside of the support base and extend obliquely upward. The movable support plate is located below the fixed support plate, and its middle portion is installed in the middle of the fixed support plate through a rotating shaft. It can be deflected on the fixed support plate, and its two ends are exposed from the outside of the support base and extend obliquely upward. The limiting ridges are adapted to the shape of the movable support plate, which can limit the deflection range of the movable support plate.

[0045] The walking transfer assembly includes walking wheels 300, and two pairs of walking wheels are provided. Each pair of walking wheels is respectively installed at both ends of the fixed support plate and the movable support plate. The supporting base, the fixed support plate and the movable support plate can be moved on the ground through the walking wheels.

[0046] The supporting and lifting assembly includes a supporting column 400, which is installed on the top of the supporting base and extends upward from the supporting base, and the overhanging hanging assembly is installed on the top of the supporting column.

[0047] The cantilever hanging assembly includes a cantilever beam 500, which is arranged in the transverse direction. A matching recess 410 is opened on the top of the supporting column. The matching recess is recessed axially toward the inside of the supporting column. The middle part of the cantilever beam is placed in the matching recess, and its two ends are folded downward to form a hanging hook body 510, and the infusion container can be hung on the hanging hook body.

[0048] The cross section of the matching inlay is rectangular, and the middle of the overhanging crossbeam is provided with a matching end head 520 of a shape matching the matching crossbeam. The matching end head is placed in the matching inlay to prevent the overhanging crossbeam from turning over.

[0049] A limit end cap 420 is installed on the top of the supporting column. The limit end cap is screwed to the outer wall of the supporting column, and its bottom is against the top of the cantilever beam to position the cantilever beam.

[0050] A limiting end ball 530 is respectively installed at the end of the hanging hook body. The diameter of the limiting end ball is larger than the diameter of the hanging hook body, which can limit the infusion container in the hanging hook body to prevent it from falling outward.
