Swinging power tool

Abstract

The invention relates to a swinging power tool. The swinging power tool comprises a shell, a motor shaft which is located in the shell and can rotate around the axis of the motor shaft, an output shaft located in the shell, an eccentric wheel connected to the motor shaft, and a shifting fork connected to the output shaft, wherein the shifting fork is provided with a pair of extension arms in which the outer circle of the eccentric wheel is wrapped, the rotary movement of the motor shaft is converted into the swinging movement of the output shaft through the shifting fork and the eccentric wheel, and shock absorption elements are arranged between the extension arms and the eccentric wheel. According to the swinging power tool, the shock absorption elements are arranged between the shifting fork and the eccentric wheel, vibration generated by impact between the shifting fork and the eccentric wheel can be reduced, the vibration of the whole machine is reduced and the noise of the whole machine is lowered by reducing the vibration in the eccentric transmission generating position, and therefore the operating comfort and the working quality of the machine can be improved.

Description

technical field [0001] The invention relates to a power tool, in particular to a hand-held oscillating power tool. Background technique [0002] The multi-function machine is a common oscillating power tool in the industry, and its working method is that its output shaft makes oscillating motion around the axis. Therefore, when different accessory working heads are installed on the output shaft, different operating functions can be realized, such as sawing, cutting, grinding, scraping, etc., to meet different working needs. [0003] The more common multi-function machines currently on the market generally include motors. The motor shaft of the motor is connected with an eccentric pin, and a bearing is sheathed on the eccentric pin, thereby forming an eccentric wheel structure. When the motor shaft rotates, the eccentric wheel structure can rotate eccentrically around the axis of the motor shaft. The output shaft of the multifunctional machine is set perpendicular to the m...

Problems solved by technology

[0004] However, since the eccentric pin is set eccentrically in the eccentric wheel structure, it will inevitably generate large vibrations due to the eccentric action surface during the entire movement process, and this vibration will always act on the eccentric wheel structure and the eccentric wheel drive on the fork

Therefore, when the user uses the multi-function machine for a long time, he will have a greater numbness in his hands, which is not conducive to the use of the user, and is also harmful to the health of the user's hands.
