Problems solved by technology

[0005] Yet the deficiency of above-mentioned multifunctional machine is: the precondition that the working head is installed on the output shaft is that the star-shaped opening of the working head matches the convex shape on the output shaft, otherwise, if it is changed to work with openings of other shapes head can not be installed on the output shaft
Therefore, the types of work heads to which the output shaft can be connected are limited

Embodiment Construction

[0068] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0069] figure 1 Shown is the head area of ​​the multifunction machine 200 in the first embodiment of the present invention. The multifunctional machine 200 includes a casing 30 , a motor (not shown) installed in the casing 30 , an output shaft 32 driven by the motor, and a working head 34 installed below the output shaft 32 . A fastener 36 passes through the working head 34 and is connected to the end of the output shaft 32 , so that the working head 34 is fixed on the output shaft 32 and can move under the drive of the output shaft 32 .

[0070] see figure 1 and figure 2 As shown, the output shaft 32 is disposed longitudinally inside the housing 30 , and its end extends out of the housing 32 for a certain distance. A shift fork 38 is installed on the output shaft 32. When the motor rotates, it can drive an eccentric device (not shown) to ...

Abstract

The invention provides a multifunctional machine. The multifunctional machine comprises an output shaft and a fastening piece, wherein the output shaft is used for mounting a working head and driving the working head to move, and the fastening piece is used for mounting the working head on the output shaft; the working head is provided with a mounting part which can be connected to the output shaft; a driving part which is in assembled connection with the working head is arranged at the rear end of the output shaft; and the driving part is provided with a friction surface which is contacted with the upper surface of the mounting part. Through the tight match between the friction surface and the upper surface of the mounting part, the multifunctional machine can be connected to the working heads in different types, so that the generality and convenience of the multifunctional machine can be greatly improved.

Description

technical field [0001] The invention relates to a multifunctional machine, in particular to a multifunctional machine capable of installing multiple different types of working heads. Background technique [0002] The multi-function machine is a common hand-held oscillating power tool in the industry. Its working principle is that the output shaft rotates and oscillates around its own axis, thereby driving the accessory working head installed at the end of the output shaft to oscillate. Common attachment heads include straight saw blades, circular saw blades, triangular sanding discs, and shovel scrapers, among others. Therefore, when the user installs different accessory working heads on the output shaft, it can realize [0003] A variety of different operating functions, such as sawing, cutting, grinding, scraping, etc., to meet different work needs. [0004] The traditional multifunctional machine is provided with a form fitting mechanism for torque transmission between ...
