ELECTRIC WRENCH
First Claim
1. An electric wrench, including:
- a main body, including a working portion and a handle, the working portion disposed at one end of the handle, the other end of the handle extending to form a holding portion;
a control unit, mounted to the main body and set with a predetermined torque value;
a torque sensor, mounted to the main body and electrically connected to the control unit, the torque sensor for sensing an output torque value of the working portion and transmitting a sensing signal to the control unit;
a vibrating module, mounted to the holding portion, the vibrating module including a shell body and a vibration motor, the shell body including a first end and a second end, the first end of the shell body being adjacent to the other end of the handle, the shell body defining a motor receiving space located at the first end of the shell body, the vibration motor disposed in the motor receiving space and electrically connected to the control unit;
wherein the vibration motor is a hidden-type eccentric load vibration motor and substantially plate-shaped;
a phonetic module, mounted to the main body, electrically connected to the control unit and including a speaker;
wherein when the output torque value of the working portion reaches to the predetermined torque value, the control unit drives the vibrating module vibrating and drives the phonetic module generating an alert signal which is broadcasted via the speaker.

Abstract
An electric wrench which includes a main body, a control unit, a torque sensor, a vibrating module and a phonetic module is provided. The main body includes a handle extend to form a holding portion. The vibrating module which includes a shell body and a vibration motor is mounted to the holding portion. The shell body includes a first end adjacent to one of the handle, and a second end. The first end defines a motor receiving space, and the vibration motor is disposed in the motor receiving space and electrically connected to the control unit. Whereby, the wrench is light-weight and friendly and comfortable for holding, and the vibration can be sensed by hand, and may produce, for example, human sound. Furthermore, the vibration and the human sound may be produced at the same time.
