[0002] When electric tools such as electric hammers and nail guns are used to drive fasteners into substrates, such as driving nails into substrates, one control method is by pressing Turning the wrench switch to start the operation of the electric tool will not only cause the motor to run idle, but also have the risk of injuring the user or damaging the non-working target. Moreover, when the electric tool is running for a long time, the internal components of the electric tool will be damaged and the service life of the electric tool will be reduced.

The invention discloses an electric tool. The electric tool comprises a striking shaft, an impact mechanism, a motor, a machine shell and a trigger switch, wherein the striking shaft comprises a striking end used for striking a fastener, at least part of the striking shaft extends in the direction of a first axis, the striking end is arranged at the front end of the striking shaft, the impact mechanism is used for outputting impact force to the striking shaft so as to drive the striking shaft to strike the fastener, the motor is used for driving the impact mechanism, the machine shell is usedfor supporting the striking shaft, the impact mechanism and the motor, the trigger switch is mounted to the machine shell so as to allow triggering by a user, the striking shaft can move forwards to afirst position along the first axis relative to the machine shell and can move backwards to a second position, and when the trigger switch is triggered, the motor is started. The invention further discloses a control method of the electric tool. The use safety performance of the electric tool is improved, and the service life of the electric tool is prolonged.
Description
technical field [0001] The invention relates to an electric tool and a control method thereof. Background technique [0002] When electric tools such as electric hammers and nail guns are used to drive fasteners into the substrate, such as nails into the substrate, one control method is to turn on the operation of the electric tool by pressing the wrench switch, which will not only cause the motor to idle, There is also a risk of injury to the user or damage to non-working objects, and prolonged idling of the power tool while on and running can wear down its internal components and reduce the life of the power tool. Therefore, the opening control method and related structure of the traditional electric tool still need to be improved. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the main purpose of the present invention is to provide an electric tool and its control method. The electric tool has high safety performance during use ...
