DETAILED DESCRIPTION OF THE INVENTION
FIG. 5 is a perspective view showing the external appearance of the shaping rod of the present invention. FIG. 6 is a front view showing the shaping rod of the present invention. FIG. 7 is a left side view showing the shaping rod of the present invention. FIG. 8 is a right side view showing the shaping rod of the present invention. FIG. 9 is a cross-sectional view taken along the line 9-9 in FIG. 6. The present invention is characterized in the design of its external appearance. The outer periphery of the rod (2) is densely provided with a plurality of small conical thorns (24), like a small hedgehog. With such an arrangement, it is very easy to wind the bundle of hairs tightly. After the bundle of hairs is wound well, a heat-resistant fixing ring is hung on the fixing teeth (21) on both ends of the rod (2) to hold the hair on the rod (2) without disheveling. By inserting a plug of about 24-volt into the socket (22), the electric heater (23) in the rod (2) generates heat to keep the temperature above 140° C. After a predetermined period of time, the degree of curl of the hairs wound on the shaping rod (2) can be set in the present invention, although the temperature of the shaping rod (2) is the same as that in prior art, yet the portions contacting with the skin are the distal ends of the thorns (24) made of a heat-resistant material having poor thermal conductivity. Therefore, the temperature of the distal ends of the thorns (24) is kept under 40° C. and will not cause any uncomfortable feeling to the skin. Indeed, the thorns (24) with lower temperature cannot hurt the skin, hence it is not necessary to provide a layer of insulator to insulate the heat from the skin. As a result, the operation of the present invention is much easier. Except for the thorns (24) densely provided on the outer periphery of the shaping rod (2), the heating method and the structure of other portions of the present invention are the same as those in prior art.
In conclusion, the thorns (24) densely provided on the outer periphery of the shaping rod (2) can facilitate the shaping rod (2) to wind the bundle of hairs tightly. Also, the operation of the present invention is very easy so that a lot of time and labor can be saved.
As can be seen from FIGS. 5 to 9, the outer periphery of the conventional shaping rod is provided densely with thorns (24) made of a heat-resistant material.
