It plays an important role in promoting industrial structure adjustment, transforming economic development methods and enhancing the competitiveness of the national economy. In order to facilitate the movement of goods, loading and unloading devices are usually used to transport the goods.

[0003] The prior art (publication number: CN 216580611 U) discloses a novel loading and unloading device, comprising a base, wherein a baffle is fixedly connected to both symmetrical sides of the base, and two columns are fixedly connected to both symmetrical sides of the top of the base, and the four columns are evenly and symmetrically distributed. A slide groove is opened on one side of the four columns, and the four slide grooves are evenly and symmetrically distributed. The four columns are grouped in pairs, and a crossbeam is fixedly connected to the top of each group of columns.

[0004] Although the above patent uses a rotating component to push and drive the pressure plate to fix the goods, it has the following disadvantages. When in use, when the worker places the goods on the base, the worker needs to slide the goods with force so that the goods move toward the side panels in sequence. The process of moving the goods requires a large amount of labor, which increases the burden on the workers and needs further improvement. For this reason, we propose a construction material loading and unloading device. Utility Model Content
