Abstract
A folding device for folding or disassembling rigid objects is provided with engaged toothed rows on opposing surfaces of two connecting plates. Opposite surfaces of protruded teeth of the toothed rows are provided with toothed grooves meshing with each other. When a locking mechanism perpendicular to a direction of the toothed rows is locked, the two connecting plates are driven by the locking mechanism to move toward each other in opposite directions along a pulling rod, so that the toothed grooves on the toothed rows tightly engage with one another, and the two connecting plates are pressed tightly and fixedly connected. When the folding device is in a connected state, meshing surfaces of the two connecting plates tightly mesh with each other through the corresponding toothed grooves, so that the two connected parts are combined together to form a whole rigid combination.
