oscillating power tool

Abstract

The invention relates to a swinging power tool which comprises a head shell, an output shaft arranged in the head shell and a shifting fork fixed on the output shaft, wherein an elastic piece is arranged between the output shaft and the head shell; the elastic piece extends along the tangential direction of the output shaft, and the centre line of the elastic line is spaced from the axis of the output shaft. With the adoption of the swinging power tool, the elastic piece which extends along the tangential direction of the output shaft is arranged between the output shaft and the head shell, the output shaft can vertically extrude the elastic piece when swinging, so that the elastic piece can effectively absorb the vibration generated by the output shaft, and further the vibration of the output shaft transferred to the head shell can be remarkably weakened, and thus the hand numbness of a user caused by vibration in the using process can be greatly improved and the operation comfort level is 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 requirements. [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 t...

Problems solved by technology

[0004] However, since the eccentric pin is set eccentrically in the eccentric wheel structure, during the whole movement process, there will inevitably be a large vibration due to the eccentric action surface, and this vibration will always act on the eccentric wheel structure and the eccentric wheel drive fork assembly

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.
