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 1

[0039] Such as Figure 1 to Figure 7 As shown, a saw blade, a working element commonly used on oscillating tools, is taken as a preferred embodiment. The saw blade includes a body part 2 and a support part 1 connected to the body part for fitting to the shaft end of a multifunctional tool. The front end of the body part 2 includes a sawtooth area 3 that can act on the workpiece to be processed to realize cutting. An adapter part 4 is provided on the support part 1 of the saw blade. The adapter part 4 and the support part 1 are integrally formed. Of course, in other implementations In the manner, the adapter part 4 may also be fixedly connected to the support part 1 by welding, riveting, screwing or other suitable connection methods. The support part 1 and the adapter part 4 form a clamping part for connecting the saw blade to the tool shaft end. The end surface of the adapter part 4 is provided with a plurality of radially penetrating grooves 5 and a plurality of protrusions ...

Embodiment approach 2

[0048] Such as Figure 8-14 Shown is the saw blade according to the second preferred embodiment of the present invention. The saw blade includes a body part 2 and a support part 1 connected to the body part. The front end of the body part 2 includes a sawtooth area suitable for acting on the workpiece to realize cutting. 3. An adapter portion 4 suitable for adapting to various shaft ends is welded on the support portion 1 of the saw blade. The support part 1 is provided with a mounting hole 7 with a longitudinal central axis Y, and a fastener such as a screw passes through the mounting hole and is connected to the shaft end when the saw blade is fixed to the shaft end. The adapter part 4 is provided with a positioning hole 310 that can limit the circumferential rotational displacement of the saw blade relative to the shaft end. The longitudinal axis of the positioning hole 310 coincides with the longitudinal central axis Y of the mounting hole 7, so that the circumferential ed...

Embodiment approach 3

[0054] Such as Figure 15 As shown, the difference between the third embodiment and the second embodiment is that the adapter part 4 in this embodiment is directly connected to the main body part 2 through the connecting handle 41 , and the support part 1 is directly connected to the adapter part 4 by welding. As for the fitting structure of the fitting part 4 , the installation structure of the supporting part 1 , and the welding connection process of the fitting part 4 and the supporting part 1 , they are all the same as those in the second embodiment, and will not be repeated here.

Abstract

A working component for mating with multiple shaft ends includes a body portion and a clamping portion which is connected to the body portion and suitable for mounting the working component to the shaft ends. The body portion has a work piece processing area for acting on the work piece to be processed and the clamping portion has a mounting hole with a longitudinal axis Y. The clamping portion includes a support portion and a mating portion which is provided with a plurality of projections which extend in a radial direction vertical to the longitudinal axis Y and which are distributed alternately.

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...
