Problems solved by technology

[0005] However, since the eccentric part is set eccentrically in the eccentric transmission structure, during the whole movement process, there will inevitably be a large vibration due to the eccentric effect, and this vibration will always act on the shift fork assembly driven by the eccentric part. on, and finally to the housing held by the operator
Therefore, if the user uses the multi-function machine for a long time, it will produce a greater numbness in the hands, which is not conducive to the use of the user, and is also harmful to the health of the user's hands.

Abstract

The invention discloses a swing power tool which comprises a motor, a shell and an output shaft extending out of the shell. The output shaft can be rotated around the self axis to do reciprocating swing motion. The shell comprises a head shell and a holding portion connected to the head shell, the output shaft is contained in the head shell, and at least one damping part is arranged in the connection area between the head shell and the holding portion. By means of the effect of the damping part, vibration produced on the holding portion can be effectively reduced, and the operation comfort level is improved.

Description

[0001] This application is a divisional application of the Chinese invention patent application filed by the applicant on April 26, 2012. technical field [0002] The invention relates to a power tool, especially a hand-held swing power tool. Background technique [0003] The multi-function machine is a common oscillating power tool in the industry, because its output shaft rotates and oscillates around the axis. Therefore, when different attachment working heads are installed on the output shaft, it can realize a variety of different operation functions, such as sawing, cutting, grinding, scraping, etc., to meet different working requirements. [0004] The more common multifunctional machines currently on the market generally include a motor. The motor shaft of the motor is connected to an eccentric member, and a bearing is sheathed on the eccentric member, thereby forming an eccentric transmission structure. When the motor shaft rotates, the eccentric transmission structu...
