[2] In general, hairstyles are an important part of the appearance in women and are utilized as means of showing their aesthetics sufficiently by changing the hairstyles in accordance with their dresses and places at all times. The importance of the hairstyles becomes serious to pursue their aesthetic interests and the capability of expressing one's individual character is judged according to the hairstyle created. Accordingly, it is a well-known fact that women endeavor to express their aesthetic sensibilities with their hairstyles.

[3] A hair curling iron that is one of the beauty tools is divided into upper and lower portions, in which a curling portion with a semicircular cross-section including a heater means, a heat generating means and a curling tool is provided, respectively. The upper and lower curling portions are opened centering on a hinge of one side thereof. A heating pad for generating heat by electricity is mounted in each of the upper and lower curling portions. Moreover, the surface layers of the respective heating pads have various winding shapes such as a round cross-sectional shape, a triangle cross- sectional shape, etc. so as to create various hairstyles by the heat generated while the hair passes through the upper and lower curling portions in accordance with the various winding shapes. With such a hair curling iron, it is possible for women to express their individual characters and aesthetic interests as described above.

[4] However, such a conventional hair curling iron has a problem in that it requires a large storage volume and it does not utilize the storage space efficiently when it is not used, since the upper and lower curling portions thereof maintain opened centering on the hinge by elastic force of a spring provided therein at all times.

[5] In order to solve such an inconvenience, various kinds of hair curling irons have been developed and used. Of them, a hair curling iron was proposed in Korean Patent

Application No. 2005-0020881 filed on March 14, 2005 and entitled "A HAIR TOOL HAVING AN APPARATUS FOR LOCKING." The above hair curling iron was developed aiming at maintaining upper and lower covers closed when it is not used, thus facilitating the storage and minimizing the volume during transportation of the product.

[6] However, the conventional hair curling irons including the above related art are configured to have various winding shapes on the surface layers of the heating pads provided on the upper and lower curling portions to create various hairstyles by the heat generated when the hair passes through the upper and lower curling portions in accordance with the various winding shapes. Here, only with the various winding shapes provided on the surface layers, it is difficult to create various hairstyles in effect.

[7] Moreover, although it is possible to express a simple hairstyle, it still has a problem in that the thus created hairstyle may not be maintained continuously.

[8] Furthermore, since the heat pads of the conventional hair curling irons are not attached and detached, it has a further problem in that, if one of the upper and lower curling portions would be damaged, the whole hair curling iron would be no longer used.
