Abstract
The invention provides an electric drill including a bracket with a handle, a drill rod, a motor assembly, and a switch assembly. The switch assembly includes a first micro switch configured to activate or deactivate the motor assembly, a switch pivotably mounted on the handle through a pivot and cooperating with the first micro switch, and a self-locking button engaged with the switch and configured as: when the self-locking button is in a first state, the self-locking button abuts against the switch to prevent the switch from rotating around the pivot; when the self-locking button is in a second state, the self-locking button is disengaged with the switch, and the switch can rotate around the pivot.
Claims16
An electric drill, comprising:
- a bracket having a handle;
- a drill rod;
- a motor assembly mounted on the bracket for driving the drill rod to rotate;
- and
- a switch assembly mounted on the handle;
- wherein, the switch assembly comprises:
- a first micro switch configured to activate or deactivate the motor assembly;
- a switch pivotably mounted on the handle through a pivot, and cooperating with the first micro switch;
- and
- a self-locking button engaged with the switch and configured as:
- when the self-locking button is in a first state, the self-locking button abuts against the switch to prevent the switch from rotating around the pivot;
- when the self-locking button is in a second state, the self-locking button is disengaged with the switch, and the switch can rotate around the pivot;
- wherein the electric drill further comprises a reversing assembly, wherein the reversing assembly comprises a second micro switch and a reversing button cooperating with the second micro switch;
- and wherein the second micro switch is configured as:
- the motor assembly reverses only when the first micro switch and the second micro switch are both triggered simultaneously.
An electric drill, comprising:
- a bracket having a handle;
- a drill rod;
- a motor assembly mounted on the bracket for driving the drill rod to rotate;
- and
- a switch assembly mounted on the handle;
- wherein, the switch assembly comprises:
- a first micro switch configured to activate or deactivate the motor assembly;
