Multi-position switch of handheld electric tool

Abstract

The invention relates to a multi-position switch of a handheld electric tool, and belongs to the technical field of electric tools. The switch comprises a switch piece arranged on the shell and a trigger located on the switch piece, the switch piece has a releasing position and a pressing position, and the trigger can swing and rotate with the two ends serving as fulcrums respectively; and a front warping plate and a rear warping plate which are located below the trigger are hinged to the shell in a spaced mode. When the rear portion of the trigger is pressed to swing around the front fulcrum, the rear portion of the trigger directly presses the switch piece downwards through the rear portion of the rear warping plate. When the front part of the trigger is pressed to swing around the rear fulcrum, the front part of the trigger enables the rear part of the rear warping plate to press the switch piece through the front warping plate. When the middle part of the trigger is pressed, the front part and the rear part of the trigger respectively act on the front warping plate and the rear warping plate, so that the rear part of the rear warping plate downwards presses the switch piece. According to the multi-position switch of the handheld electric tool of the invention, no matter where the trigger is pressed, the switch piece can be easily operated in a labor-saving manner.

Description

technical field [0001] The invention relates to a push control switch, in particular to a multi-position switch of a hand-held electric tool, which belongs to the technical field of electric tools. Background technique [0002] Hand-held electric tools such as angular impact screwdrivers and angular impact wrenches are provided with push-type control switches at the gripping parts. In order to facilitate different manipulations in various application occasions, the grip part and the trigger of the control switch usually have a certain length. The U.S. patent application number US8853578B discloses a power tool, comprising: a housing; an elongated paddle element (i.e., trigger) with a first end and a second end, which includes an input surface, and the first end can be directed toward and Moving away from the housing, the second end is movable towards and away from the housing; a support surface disposed on the paddle element; a switch mechanism having a first position and a...

[0003] However, when in use, pressing the front or rear of the trigger of the control switch feels easy and labor-saving, while pressing the middle of the trigger is obviously laborious. As a result, not only does the control feel bad, but also it is easy to get tired when holding the middle of the trigger
