Abstract
An oscillatory power tool that is capable of using various types of cutting tools is disclosed. The power tool includes an output shaft for mounting one of the cutting tools and driving the cutting tool in an oscillating rotary motion. An end of the output shaft has a driving section for engaging with a securing section of the cutting tool. The power tool further includes a fastener connected to the output shaft at the end and connectable to the securing section of the cutting tool for fastening the cutting tool to the end of the output shaft. The driving section has a fitting surface for contacting a surface of the securing section. Through a close fit between the friction surface and the surface of the securing section, the power tool can be connected with different types of cutting tools, which greatly improves the universality and convenience of the power tool.
