Abstract

A multifunctional tool and a rapid replacement structure thereof, comprise an output shaft assembly. An elastic chuck (16) capable of moving axially is arranged in the output shaft assembly. A locking shaft (10) is arranged in the elastic chuck (16) and driven by an elastic assembly to move axially in the elastic chuck (16), thus expansion opening and closing of the elastic chuck (16) are achieved. The present invention controls the axial sliding of the output shaft assembly and the locking shaft assembly by rotating a knob at the head of the machine, thus the saw web is controlled to be loosened or clamped and the rapid replacement function 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. ...
