Problems solved by technology

[0006] Oscillating power tools are less efficient in use due to the smaller swing angle, which is a problem that people have been unable to solve
In addition, the small swing angle will also bring other problems. For example, when using a straight saw blade for slotting, the sawdust is not easy to discharge, which will cause the saw blade to heat up and wear out, and the saw blade will be easily stuck.
The swing angle is small, and the application function of the swing power tool is limited at the same time, and it is not convenient to expand the working head to realize other more application functions, such as mowing, drilling, hammering, etc.

Embodiment Construction

[0088] Combine below Figure 1 to Figure 6 , First, the first embodiment of the present invention will be described.

[0089] see figure 1 and figure 2 , an oscillating power tool, especially a hand-held oscillating power tool, that is, a multifunctional machine 100, includes a casing 1 and an output shaft 2 extending from the casing 1 and extending vertically. Wherein, a motor 3 , a motor shaft 4 driven to rotate by the motor, and an eccentric transmission mechanism 5 arranged between the motor shaft 4 and the output shaft 2 are arranged in the casing 1 . The motor shaft 4 is substantially perpendicular to the output shaft 2 , and the rotation of the motor shaft 4 is converted into the rotary reciprocating swing of the output shaft 2 through the eccentric transmission mechanism 5 . The end of the output shaft 2 is equipped with a saw blade 6 which is an attachment of the working head, and the output shaft 2 can drive the saw blade 6 to rotate and reciprocate around its ow...

Abstract

The invention discloses a swinging power tool, which comprises a shell, a motor, a motor shaft, an output shaft and an eccentric transmission mechanism, wherein the motor is arranged in the shell; the motor shaft is driven by the motor; the eccentric transmission mechanism is arranged between the motor shaft and the output shaft; the motor shaft is used for driving the output shaft to swing around the axis of the output shaft in a reciprocating way through the eccentric transmission mechanism; and the swinging angle of the output shaft is greater than 4 degrees. The swinging angle of the output shaft is increased, so that the working efficiency of the swinging power tool is increased, and more application functions can be extended for the swinging power tool.

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 hand-held oscillating power tool in the industry. Its working principle is that the output shaft oscillates around its own axis. Therefore, when the user installs different working head attachments on the output shaft, a variety of different operating functions can be realized. Common working head accessories include straight saw blades, circular saw blades, triangular abrasive discs, scrapers, etc., which can realize work requirements such as sawing, cutting, grinding, and scraping. [0003] Traditional oscillating power tools usually include a head shell, a motor set in the head shell, a main shaft driven by the motor, and an eccentric mechanism set on the main shaft. The eccentric mechanism converts the rotational motion of the main shaft into the reciprocating swing of the drive shaft to d...
