[0002] A lifting rack refers to a rack for supporting and lifting objects. When installing lamps for fine decoration projects, you will encounter lamps of various shapes. Crystal lamps, in particular, are expensive, complicated to install, and easily broken and damaged, causing serious losses to accessories. Some lamps require two or even more workers to lift the lamps to the top, which is labor-intensive and labor-intensive to install. Therefore, a lifting rack is needed to lift the lamps for easy installation.

[0003] The existing towing rack for hardcover lamps (Announcement No.: CN220131781U) has at least the following disadvantages:

[0004] When lifting the lamp, the handle needs to be rotated manually to drive the gear, transmission chain, second gear and rack to rotate, and the rack drives the supporting sub-rod to move in the supporting main rod. However, the moving range of the lamp during the lifting process is approximately the length of the supporting sub-rod, so that the highest point of the lifting is approximately the height of the supporting sub-rod and the supporting main rod. When a higher lifting height is required, it is difficult to further meet the demand, and a towing rack for fine-decorated lamps is urgently needed to solve the above problem. Utility Model Content
