With the spread of portable terminals, the number of users is increasing. When making a call with a portable terminal, the user must hold the portable terminal with one hand, so there is no problem in normal use, but if the user uses the portable terminal while driving, Because you have to talk while driving with your hands, you can't cope with sudden accidents and inadvertent driving leads to a very dangerous situation.

Therefore, as a way to overcome the above problems, the hands-free device for allowing a user to use a portable terminal without using a hand while driving in recent years has been widely used and very useful.

However, in order to mount such a hands-free device inside a vehicle, after fixing the attachment bracket for fixing the hands-free device to a separate position by using a screw or the like, the hands-free device is placed on the support, and the hands-free device is operated. Since the power line connected to the vehicle battery must be connected, and it is preferable to fix the speaker or microphone close to the driver in order to increase the call sensitivity in positioning the speaker or microphone configured to extend from the hands-free device, Hands-free device users fix the speaker or microphone to a sun visor that blocks the light located adjacent to the driver's seat, and it is very difficult to install the hands-free device in a car because it must be processed so that the connection line connected to the hands-free device is not stretched. There is a difficult problem.

In addition, in recent years, a cigar jack type hands-free device in which a connector that is inserted into a cigar jack is integrally formed on one side of the hands-free device has been proposed. However, in the case of such a cigar jack type hands-free device, the position of the speaker or microphone, which is configured to extend to the outside, should be fixed to a position close to the driver, and at the same time, a connection line extending from the hands-free device is extended. There is a problem that must be processed so that the connection line is not stretched by using a groove in the car.

Most users of the conventional hands-free device or cigar jack-type hands-free device have a speaker or microphone extended outside the driver's seat to improve the call sensitivity, so it is fixed to the sun visor located close to the driver. The sun visor is then moved to perform its unique function of blocking light.
