The present invention provides an adapter (14) for coupling an accessory tool (24) to any of a plurality of power tools, wherein each of the plurality of power tools has a different tool drive structure ( 50a, 50f). The adapter includes a body (100) including a first side surface (104) and a second side surface (108) positioned opposite the first side surface. An inner peripheral surface (110) extending from the first side surface to the second side surface, the inner peripheral surface defining a central opening (112), and an outer peripheral surface (114) extending from the first side surface to the second side surface the second side surface. A plurality of recesses (106, 107) positioned about the central opening are defined in the first side surface. Additionally, the body has a first adapter drive structure (120, 124) and a second adapter drive structure (126). The first adapter drive structure and the second adapter drive structure define the plurality of recesses, the first adapter drive structure and the second adapter drive structure respectively having different configurations from each other. The first adapter drive structure is configured to mate with a first tool drive structure of a first of the plurality of power tools, and the second adapter drive structure is configured to mate with the plurality of power tools Cooperate with the second tool driving structure of the second electric tool in the tool.
Description
technical field [0001] The present invention relates to the field of power tools, and more particularly to adapters for securing accessories to tool holders of power tools. Background technique [0002] Typically rotary and oscillating tools are lightweight hand-held power tools that can be equipped with a variety of tool accessories and accessories such as cutting blades, grinding wheels, grinding tools, etc. These types of tools, hereinafter referred to as power tools, typically include a substantially cylindrical body that acts as an enclosure for the motor and a handle for the tool. The motor is operatively coupled to a drive member extending from a portion of the body of the power tool, referred to herein as a tool holder. The motor is configured to rotate and / or vibrate the tool holder at a relatively high frequency. The tool holder is configured to hold different accessory tools such that the tool holder is moved by the motor, and the accessory tool fixed on the hol...
