Embodiment Construction

[0014] Please refer to Figure 1 to Figure 3 , an electric power tool 100, comprising a housing 1, a motor 2 accommodated in the housing 1, an output shaft 3 matched with the motor 2, a power supply system 4, and a float switch 5 electrically connecting the power supply system 4 and the motor 2 .

[0015] The housing 1 is used to cover the components in the electric tool 100 and can be held by an operator. The casing 1 includes a first casing 11 and a second casing 12, and the first casing 11 and the second casing 12 can move relative to each other. The first casing 11 is provided with a motor installation slot and a battery compartment. The second housing 12 is provided with a guide slot through which the output shaft 3 passes. The second housing 12 is also provided with mounting slots for receiving bearings.

[0016] The motor 2 is an ordinary DC motor, and is installed in the motor installation slot of the first casing 11 .

[0017] The output shaft 3 is connected with...

Abstract

An electric tool comprises a casing, a motor accommodated in the casing, an output shaft matched and connected with the motor and a power supply system electrically connected with the motor. The electric tool is characterized in that the end face of the casing away from the output shaft is provided with a float switch which is pressed in the extending direction of the output shaft, and the float switch is electrically connected with the motor and the power supply system. The electric tool further comprises a control system connected with the motor and used for controlling the motor.

Description

technical field [0001] The invention relates to an electric tool. Background technique [0002] Traditional electric tools, such as electric drills, screwdrivers, etc., are provided with a handle for holding, and a trigger is provided on the handle. The part perpendicular to or intersecting with the handle is provided with a motor and an output shaft. When working, the operator holds the handle to apply pressure to the work object such as workpiece or screw, and the triggering direction of the trigger is opposite to the direction of force application. In this way, the operator needs to apply two forces in opposite directions. Especially when the vibration is large, the operator's finger must always press the trigger. Keeping the fingers in the same state for a long time is likely to bring occupational diseases to the operator. [0003] Therefore, on the basis of intensive research on the prior art, the inventor provides an electric tool that is easy to operate. Content...
