Patent ID: 10694672

Abstract:
Systems and methods for using interchangeable tool attachments in multi-use tools. In one embodiment, a multi-use tool includes a motor, a shaft and a shaft adapter at the end of the shaft. The motor has user controls (e.g., on/off switch or throttle) that control the motor to drive the shaft and cause it to rotate. The shaft may include a rigid tubular outer member with a flexible inner shaft. The shaft adapter is coupled to the end of the rotating portion of the shaft. The shaft adapter has a mounting flange that rotates with the adapter at the end of the shaft. An interchangeable tool attachment is secured to the mounting flange, and rotation of the shaft adapter and mounting flange causes the tool attachment to rotate as well. Many different tool attachments can be interchangeably secured to the mounting flange to provide corresponding, different functions to the tool.
