Problems solved by technology

[0003] At present, there are several brands of multi-function tools on the market, such as DREMEL, FEIN, and WORX. Each brand of multi-function tool is equipped with its own brand of working components, but the working components of each brand cannot be used in common, that is, Say, when a user purchases a certain brand of multi-function tool, if he needs to purchase a replaceable working element, he can only buy the working element of this brand, and the working element of other brands cannot be installed in the multi-function tool he owns. superior
Therefore, the existing working elements do not have good versatility, which brings troubles to users

Embodiment approach

[0035] Such as Figure 1 to Figure 3 As shown, it is the first embodiment of the working element of the present invention that can be adapted to various shaft ends. The working element is a saw blade commonly used on multi-function tools as an example. The saw blade includes a body part 2 and a body part 2 The connecting part 1 is used to be adapted to the shaft end of the multi-function tool. The front end of the body part 2 is a sawtooth area 3 acting on the workpiece to be processed. A mounting hole 7 is provided on the connecting part 1. The mounting hole 7 has a longitudinal axis 8. The radial direction of the mounting hole 7 is perpendicular to the longitudinal axis 8 . The connecting part 1 of the saw blade is provided with an adapter part 4, and the adapter part 4 is fixedly connected to the connecting part 1 by means of welding, riveting or screws. Of course, the adapter part 4 and the connecting part 1 can also be integrally formed. . The fitting part 4 is provided...

Abstract

The invention provides a working component capable of being fit with various shaft ends. The working component comprises a body portion and a connection portion, wherein the body portion is provided with a cutting edge zone acting on a workpiece to be processed; the connection portion is provided with a fit portion fit with the shaft end; the fit portion is provided with a polygonal fit hole; and bulges and grooves which are radially arranged alternately extend outwards from the polygonal fit hole. The working component has the following beneficial effects: the working component can be fit with shaft ends in various shapes; and meanwhile, an adapter is directly arranged on the connection portion of the working component, thus reducing the accessories of multifunction tools and ensuring the multifunction tools to have portability.

Description

technical field [0001] The invention relates to a working element, in particular to a working element for fitting onto the shaft end of an output shaft capable of being driven by oscillation. Background technique [0002] At present, there are some multifunctional tools with replaceable working elements on the tool market. The replaceable working elements are installed on the output shaft end of the multifunctional tool, so that the multifunctional tool has multiple uses, and thus can be applied to various working occasions. The multi-function tool is also called an oscillating tool. Its working principle is: a motor driver is installed in the body of the multi-function tool, and the eccentric output shaft installed in the spherical bearing is driven by a shift fork to make an oscillating motion, thereby driving the working element to make an oscillating motion , to realize the processing of the workpiece to be processed. Different working elements have different special pu...
