[0028] Working principle: when in use, the logistics objects will be transported by the transmission belt and placed on the lifting platform 4 on one side of the lifting pillar 2. The support bar 401 of the lifting platform 4 can support the bottom of the logistics package, and the lifting platform 4 is also rotatably connected with a support plate 6. The support plate back plate 601 arranged on the support plate 6 can support the back of the logistics package, and the support plate back plate 601 on the support plate 6 is mutually adsorbed with the lifting platform back plate 402 of the lifting platform 4 through the second magnetic suction plate 605 and the first magnetic suction plate 403. The lifting platform back plate 402 is provided with a side of the first magnetic suction plate 403 as an inclined surface, so when the support plate back plate 601 leans against the lifting platform back plate 402, it will also tilt. When stacking packages, the package pile can be slightly tilted inward to prevent the stacked logistics packages from tipping outward due to centrifugal force when the base 1 rotates;

[0029] When a forklift takes away the stacked logistics packages on the lifting platform 4, the end of the fork frame of the forklift will contact the push plate 603 under the support plate back plate 601 when it is inserted into the bottom of the lifting platform 4, and drive the push plate 603 to move inward, so that the support plate 6 and the support plate back plate 601 are driven to rotate outward through the support plate rotating shaft 602, so that the forklift can take away the stacked logistics packages.

[0030] A first telescopic rod 5 and a second telescopic rod 502 are arranged between the support plate back plate 6 and the lifting platform support plate 402 of the lifting platform 4. A third telescopic rod 504 is also provided inside the second telescopic rod 502 for sliding connection, and is contracted by a spring 507 inside a telescopic slide groove 506 connected thereto. After the forklift moves away, the support plate back plate 601 of the support plate 6 can be pulled toward the lifting platform support plate 402, and finally tilted against the lifting platform support plate 402, thereby restoring the inclination of the support plate 6 and the support plate back plate 601, which is convenient for subsequent package stacking.
