发明名称 One piece speed wrench
摘要 A one-piece speed wrench has a handle and two engagement prongs joined at an engagement area. One prong, the in-line prong, may be parallel with the length of the handle. The other prong, an offset angle prong, contains at least one notch. The notch has two faces. When viewed from the side, one face, the inboard face closest to the engagement area between the two prongs, is at an angle with the face of the in-line prong. The inboard face of each notch is in a preferred embodiment approximately a third as long as each face of the hexagonal fastener. The outboard face adjacent to the inboard face of each notch is at a decreasing angle with the in-line prong in the direction away from the prong engagement area. This decreasing angle of the outboard face of each notch allows for a ratcheting effect. There may be more than one notch, with each notch corresponding to a different size hexagonal fastener. The tool of this invention offers the function of an expensive ratchet type tool and will fit multiple size fastener heads. This tool has no moving parts but still allows a ratcheting effect when used on fasteners.
