Abstract: A storage box includes a bottom casing, a top cover, two hinge coupling plates, and a button seat. Both the bottom casing and the top cover have an interior defining a chamber. The rear sides thereof are respectively provided with hinge coupling seats each of which is provided with fastening holes for engaging corresponding bulges on the leaves of the hinge coupling plates to allow opening or closing of the box. The front side of the bottom casing is provided with a fastener coupling seat for receiving the button seat. The front side of the top cover is provided with a fastening groove for engaging a projecting hook of the button seat. The hinge coupling plates are configured to be multi-piece coupling elements with contacts at the middle section thereof to ensure that the contacts will not easily break. The leaves of the hinge coupling plates are bendable. Each coupling element has a slot which is integrally connected to a reinforcing strip.

Abstract: A tool handle including a handle body having a backwardly opened receiving chamber and longitudinally disposed peripheral opening, a rotary storage wheel mounted in the receiving chamber and having longitudinal storage grooves spaced around the periphery for holding tool bits and accessories, and a rotary knob fastened to the rotary storage wheel and disposed outside the handle body and adapted for turning the rotary storage wheel to move the longitudinal storage grooves into alignment with the longitudinal opening of the handle body alternatively for loading/unloading tool bits and accessories.

Abstract: A tool handle for hand tools, including: a handle body having a polygonal coupling hole at a front end thereof adapted for holding a tool bit, two raised grip portions and two longitudinal open chambers alternatively arranged around the periphery, each longitudinal open chamber having an upper receiving section, a bottom coupling section, and two grooves in the bottom coupling sections at two opposite ends; and two tool boxes respectively mounted within the longitudinal open chambers of the handle body, each tool box including a box body adapted for loading in the upper receiving section of one longitudinal open chamber of the handle body, two outward coupling flanges bilaterally raised from the box body and adapted for coupling to the bottom coupling section of one longitudinal open chamber of the handle body, two tongues raised from a bottom side of the box body at two opposite ends and adapted for engaging the grooves of one longitudinal open chamber of the handle body, and a plurality of tool holes define
