Problems solved by technology

[0004] However, since the eccentric pin is set eccentrically in the structure of the eccentric wheel, it is inevitable that a large vibration will be generated due to the eccentric effect during the whole movement process, and this vibration will always act on the structure of the

Example Embodiment

[0037] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0038] See figure 1 , figure 2 with image 3 , An oscillating power tool, especially a hand-held oscillating power tool 100, includes a housing 1 and an output shaft 2 extending from the housing 1. Wherein, the housing 1 includes a body shell 11 and a head shell 12, which are connected together by bolts and form a receiving cavity 13. A motor 3 and a motor shaft 4 driven to rotate by the motor 3 are arranged in the body shell 11, and an eccentric transmission mechanism 5 between the motor shaft 4 and the output shaft 2 is arranged in the head shell 12. The motor shaft 4 is substantially perpendicular to the output shaft 2, and the rotation of the motor shaft 4 is converted into the reciprocating swing of the output shaft 2 around its axis X through the eccentric transmission mechanism 5. When different working head accessories are connected to the ...

Abstract

The invention provides a swing-type power tool. The swing-type power tool comprises a shell, a motor arranged in the shell, an eccentric transmission mechanism driven by the motor, and an output shaft which is driven by the eccentric transmission mechanism to swing back and forth around an axis of the shaft, wherein, a support is connected on the output shaft; and elastic components are arranged between the support and the shell. The swing-type power tool provided by the invention has the beneficial effects that by virtue of the action of the elastic components, vibration generated by the output shaft can be effectively absorbed so as to improve operation comfortability.

Description

technical field [0001] The invention relates to a power tool, especially a hand-held swing power tool. Background technique [0002] 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. [0003] The more common multi-function machines currently on the market generally include a motor. The motor shaft of the motor is connected to 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 motor shaft, and a s...
