Problems solved by technology

In the process of assembling and disassembling the working head, it is often necessary to support the working head by hand, especially for gun drill power tools with automatic clamping, often the working head has been clamped, but the output shaft of the power tool is still rotating , so that the working head will rotate with the output shaft. At this time, the operator does not know whether the working head has been clamped, but will continue to support the working head with his hands. At this time, the rotating working head may cut the operator operator's hand, causing injury to the operator

Embodiment Construction

[0037] An electric drill is one form of power tool to which the present invention is applicable. For convenience, an electric drill is used as an example to describe the present invention below, but it should be understood that the present invention has wider application and is suitable for various other power tools, such as electric screwdrivers and electric hammers. Specifically, it will be described through the following embodiments. The power tool includes an output shaft that drives the working head to work, the output shaft has an output shaft axis,

[0038] figure 1 It is a schematic structural diagram of an electric drill in a preferred embodiment. The electric drill 100 includes a casing 30 arranged horizontally, a handle 32 arranged at a certain angle to the casing 30 , and a detachable battery pack 34 at the bottom of the handle 32 . The casing 30 is provided with a motor (not shown) and an output shaft 36 driven to rotate by the motor. An automatic chuck 38 is pr...

Abstract

The invention relates to a supporting device and a power tool provided with the same. The supporting device is used for assisting the power tool to position a working head, and comprises a main body, a supporting mechanism and an elastic element, wherein the supporting mechanism comprises at least three supporting pieces which are movably connected onto the main body, and connecting pieces which are connected with the supporting pieces and move with the supporting pieces; the elastic element is arranged between the supporting mechanism and the main body and is used for providing elastic force to promote the supporting pieces to have a trend of moving to a supporting position of a supporting working head. The supporting device and a power tool provided with the same can prevent possible safety problems when an operator supports the working head with hands during working head dismounting.

Description

technical field [0001] The invention relates to a supporting device and a power tool equipped with the supporting device. Background technique [0002] Power tools typically include hammers, drills, screwdrivers, and impact drills, among others. When using these power tools, the operator often assembles and disassembles the working head as required. In the process of assembling and disassembling the working head, it is often necessary to support the working head by hand, especially for gun drill power tools with automatic clamping, often the working head has been clamped, but the output shaft of the power tool is still rotating , so that the working head will rotate with the output shaft. At this time, the operator does not know whether the working head has been clamped, but will continue to support the working head with his hands. At this time, the rotating working head may cut the operator operator's hand, and cause injury to the operator. [0003] In view of this, it i...
