Embodiment Construction

[0035] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0036] Such as Figure 1-8 As shown, it is the best embodiment of the present invention, the output shaft assembly of the multi-function tool is provided with an axially movable elastic collet 16, and the elastic collet 16 is provided with a locking shaft 10, and the locking shaft 10 It is driven by the elastic component to move axially in the elastic clip 16, so as to realize the opening and closing of the elastic clip 16.

[0037] The detailed structure description is as follows:

[0038] The output shaft assembly includes a main output shaft 14 and an auxiliary output shaft 1 of an integral structure, the upper half of the auxiliary output shaft 1 is loca...

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.

Description

technical field [0001] The invention belongs to the technical field of electric tools in the machinery industry, and in particular relates to a multifunctional tool capable of various operations such as cutting and sanding and a quick-change structure thereof. Background technique [0002] The multi-function tool can hold woodworking saw blades, metal saw blades and triangular sanding discs, etc. The clamped woodworking saw blade or metal saw blade can be used for cutting and processing on metal materials such as wood or aluminum alloy, and the triangular sand disc can be used for sanding and polishing on wood, plasterboard or walls after sticking sandpaper. [0003] The saw blade and the triangular sand disc are installed on the output shaft of the multi-function tool. There are small bosses evenly distributed around the circumference on the output end surface of the output shaft. The small bosses are used for the positioning of the saw blade and the triangular sand disc. ...
