Abstract

An electric tool includes a housing, a drive mounted inside the housing, a circuit board mounted inside the housing and electrically connected with the drive, a first connection port electrically connected with the circuit board and exposed outside the housing, and a controller. The controller has a second connection port configured corresponding to the first connection port in a way that the second connection port is detachably and electrically connectable with the first connection port. Connecting the second connection port of the controller with the first connection port of the electric tool enables a user to set operating parameters of the electric tool subject to his/her actual needs through the controller so as to control the operating status of the electric tool.

Claims

1. An electric tool, comprising:

a housing;

a drive mounted inside the housing;

a circuit board mounted inside the housing and electrically connected with the drive;

a first connection port electrically connected with the circuit board and exposed outside the housing; and

a controller having a second connection port configured to be detachably and electrically connectable with the first connection port.

2. The electric tool of claim 1, wherein the drive is a brushless motor.

3. The electric tool of claim 1, wherein the first connection port is a USB port.

4. The electric tool of claim 1, wherein the controller comprises a display unit for showing a serial number of the electric tool, a total time of operation of the electric tool, or a total frequency of operation of the electric tool.

5. The electric tool of claim 1, wherein the controller comprises a display unit for showing a value of an accumulative frequency of operation counted by the controller, and a button for being pushed to reset the value to zero.

6. The electric tool of claim 1, wherein the controller comprises a display unit for showing a current revolution speed of the electric tool, a first button for being pushed to increase the current revolution speed, and a second button for being pushed to decrease the current revolution speed.

7. An electric tool for being electrically connected with an external controller, the electric tool comprising:

a housing;

a drive mounted inside the housing;

a circuit board mounted inside the housing and electrically connected with the drive; and

a first connection port electrically connected with the circuit board and exposed outside the housing for being detachably and electrically connected with the external controller for enabling the electric tool to be electrically connected with the external controller.

8. The electric tool of claim 7, wherein the drive is a brushless motor.

9. The electric tool of claim 7, wherein the first connection port is a USB port.
