Abstract

The invention provides an electric tool and a safe starting method, a pressure sensor is arranged on a holding part of the electric tool, the pressure sensor is used for sensing the holding force, and a controller controls whether the electric tool is started or not by analyzing whether the holding force meets a preset condition or not and combining the state of a switch. Wherein the preset condition of the holding force is used for distinguishing whether a person holding the electric tool is a child or a non-child, and when the child holds the tool, the holding force inevitably does not meet the preset condition for starting the electric tool, so that potential safety hazards and property loss caused by the fact that the child starts the electric tool without a guardian can be avoided; and the personal safety and property safety of children can be effectively protected. Meanwhile, when the machine is started, other specific operations are not needed, and individual identity verification is not needed either.

Description

technical field [0001] The invention relates to the technical field of electric tools, in particular to an electric tool and a starting method thereof. Background technique [0002] In the 1960s, with the development of battery manufacturing technology, battery-type power tools without power cords that used nickel-cadmium batteries as power sources appeared. There are many kinds of tools, such as electric drills, electric screwdrivers, electric wrenches and electric grinders, etc. Most of the existing electric tools can enter the working state after pressing the switch. If non-professionals such as children accidentally touch the switch, the electric tool will enter the working state. The electric tool in operation may cause personal injury or property loss. Low security and reliability. Especially for naughty children by nature, when the guardian is not around, the children like to take out the electric tools to play, and it is very easy to hurt the children after startin...
