[0002] Construction engineering refers to the engineering entity formed by the construction of various types of buildings and their ancillary facilities and the installation of supporting lines, pipelines, and equipment. "Buildings" refer to projects with roofs, beams, columns, walls, foundations, and internal spaces that can meet people's needs for production, living, learning, and public activities. During the construction process, lifting devices are required to transport materials.

[0003] A Chinese patent with publication number CN219860381U discloses a lifting device for building materials. By setting a servo motor, a stud, a connecting rod, a building material placement plate, a hydraulic telescopic column, a moving block, a connecting block and a pushing plate for coordinated use, the servo motor rotates to drive the building material placement plate to move up and down and the hydraulic telescopic column drives the pushing plate to push the material, thereby achieving the advantages of lifting and unloading building materials, and solving the problem that the building materials on the construction site are generally transferred manually to high and low places, which has high labor intensity, high labor input and low construction efficiency. At present, there are not many tools suitable for material transfer on the construction site, and users are usually required to manually rotate them to lift them, which is inconvenient for users to use.

[0004] However, the lifting device in the above scheme is relatively large in size, occupies a lot of space, is not convenient to carry and transport, and when not in use, workers are prone to accidentally touch it, causing injuries to the workers.

[0005] Therefore, it is necessary to invent a material lifting device that is used for construction engineering. Utility Model Content
