The present invention relates to a SLIDING OPENING AND CLOSING MECHANISM OF CELLULAR PHONE, and more particularly to a sliding type opening and closing device for a mobile phone that can perform two-way opening and closing, and The opening and closing are smoothly performed during the opening and closing operations, and the convenience in use is achieved.

Recently, with the increase in the spread rate of electronic devices, such as portable wireless mobile phones, portable mobile phones are required to have not only the inherent functions of pure wireless communication but also an additional function that meets the user's interest in the opening and closing operation. According to these requirements, portable mobile phones have evolved from a general bar type to a flip type, a flip up type, a folder type, etc., and recently the folding mobile phone has become Mainstream.

This is because the foldable mobile phone has enough space to use the widescreen LCD module as a display device, and can be folded in half and carried, so it is superior in portability to other mobile phones.

On the other hand, there is also known a slide type mobile phone which can be provided as a display device having a widescreen LCD module of a size similar to that of a foldable mobile phone, and contributes to miniaturization of a mobile phone.

Such a slide type mobile phone realizes opening and closing by sliding a sub-body corresponding to the cover on the main body, thereby having the following additional advantages: In the case of directly following the advantages of the existing folding mobile phone, the opening and closing is performed with a new action.

As a slide type mobile phone, a slide type portable type wireless mobile phone is disclosed in Korean Utility Model Registration Application No. 2003-0000136.

The mobile phone disclosed in the application includes: a guiding mechanism for guiding the auxiliary body on the main body; and at least one elastic mechanism disposed between the auxiliary body and the main body, based on a certain sliding position of the auxiliary body Change the direction of the force in the opening or closing direction.

Moreover, the maximum open position or the maximum closed position can be maintained by the elastic mechanism when the secondary body is fully opened or closed, without the need for additional stops.

A torsion spring which is fixed to the main body at one end and fixed to the auxiliary body at the other end is used as the elastic mechanism.

For such a mobile phone, since one end of the torsion spring is fixed on the main body and the other end is fixed on the auxiliary body, the elasticity of the torsion spring acts on the entire moving distance of the auxiliary body, so the torsion spring is greatly tensioned or stretch.

Therefore, a torsion spring having a large movement and a small elastic force is used, and in order to supplement the shortage of the elastic force, two torsion springs are disposed.

Therefore, the conventional opening and closing device described above has a problem that the torsion spring is largely deformed, so that the torsion spring is easily deteriorated due to the fatigue caused by the reverse operation, and the normal opening and closing function is quickly lost.

In order to solve such a problem, the following method is adopted in the Korean Patent Registration Publication No. 10-698458: as shown in FIG. 1, when the guide hole 212 is formed.
