[0017] The utility model has the advantages of:

[0018] 1. The stacker truck lifting mechanism proposed in this utility model, when entering a relatively narrow passage, the first motor drives the lead screw to rotate, causing the slider to slide outside the lead screw, which causes the rotating block to rotate and drive the support plate to move in opposite directions. The support plate will slide outside the guide rod, and the rotating rod will slide outside the drive shaft. At the same time, the connecting block will drive the first rack to slide in opposite directions inside the moving block. This not only allows the stacker truck to pass through narrow passages smoothly, but also allows the stacker truck to work in warehouses or work sites with different layouts, reducing the restrictions on the working environment and improving the versatility of the stacker truck.

[0019] 2. The stacker lifting mechanism proposed in this utility model, when lifting goods, the second motor drives two drive shafts to rotate, so that the rotating rod and the first bevel gear rotate synchronously. The rotation of the first bevel gear will drive the second bevel gear meshing with it to rotate synchronously, thereby causing the connecting block outside the threaded rod to drive the moving block and the mounting block to move up and down synchronously, ultimately realizing the stable lifting of goods on the fork. When translating the fork, the third motor drives the rotating shaft to rotate, causing the first spur gear and the second spur gear to rotate. When the second spur gear rotates, it will drive the mounting block to slide outside the moving block, thereby realizing the translation of the fork and improving the adaptability of the stacker to different working scenarios.
