Abstract

The invention belongs to the technical field of electric tools in the machine industry, and particularly relates to a multifunctional tool and a rapid replacement structure thereof. The multifunctional tool can perform cutting, sanding and the like. The rapid replacement structure comprises an output shaft assembly. An elastic chuck capable of moving axially is arranged in the output shaft assembly. A locking shaft is arranged in the elastic chuck and driven by an elastic assembly to move axially in the elastic chuck, and then expansion opening and closing of the elastic chuck are achieved. According to a traditional replacement method, screws on a saw web and a triangular sand tray are completely detached, the saw web or the triangular sand tray is arranged in a sleeving mode, then the screws are screwed up through a hexagon wrench, consequently, replacement efficiency is low, the hexagon wrench is prone to being lost, and replacement can not be performed once the hexagon wrench is lost. By means of the multifunctional tool, it is not needed to fix the saw web with one screw, axial sliding of the output shaft assembly and a locking shaft assembly is controlled by rotating a knob at the head of the multifunctional tool, then the saw web is controlled to be loosened or clamped, and therefore rapid replacement is achieved.
