    Abstract: A multi-functional workbench disclosed herein includes a worktop and supporting legs. The worktop is provided with a girder. The bottom of the girder is provided with a receiving space. Concave-shaped mechanisms are affixed in the receiving space and are connected by square tubes. The supporting legs are rotatably attached to the square tubes and can be received in the receiving space. The workbench further includes one or more locking mechanisms. A first locking mechanism is installed between two supporting legs attached to the same square tube. The first locking mechanism prevents the supporting legs from being disengaged when engaged into the concave-shaped mechanisms. More locking mechanisms can be added to secure the supporting legs when they are folded. The multi-functional workbench can be converted into a worksurface, a sawhorse, a step tool, a creeper, or a pulling tractor.
