This lock button 24 is provided on the surface of the first holder 1 opposite to the second holder 2 so as to be slidable in the longitudinal direction of the first holder 1, and on the second holder 2 side of the first holder 1. A hole 25 is formed, and a locking portion 26, which is an example of a hook extending from the lock button 24, is located in the hole 25. 27 is the transparent window of the pilot lamp 22,
28 is a lead wire, and 29 is a power cord drawn out from the rotary connector 19.

The hair holding plate 4 is a metal plate having an arcuate cross section with a radius of curvature equal to or larger than the outer diameter of the heating rod 3, and when the rear end is bent in steps and pressed against the heating rod 3, the heating rod 3
5, a hook piece 4a for locking is cut and raised at the rear end, and a hook hole 4b is formed at the tip of the hook piece 4a. ing. The second holder 2 consists of a main body 30 and a main body cover 31. The rear end of the hair press plate 4 is fixed to the tip of the main body 30 with a pair of tatu pin screws 32, 33, and the main body cover 31 covers it. ing. At this time, the hooking piece 4a is made to protrude from the hole 34 of the main body cover 31 toward the first holder 1 side. Further, a bearing 35 is provided at the rear end 2a of the second holder (main body) 2, and when the bearing 35 is fitted into the housing of the first holder 1, the rear end 2a of the second holder 2 is inserted into the connection opening 17. The spring 5 formed by a coil spring is interposed and held between the bottom surface 17a of the connection opening 17 and the flat surface 36 that fits into the connection opening 17 of the rear end portion 2a. ing. In this way, the first holder 1 and the second holder 2 are rotatably connected by the shaft 16, are biased open by the spring 5, and moreover, by sliding the lock button 24 of the locking means 6, the first holder 1
And when the second holder 2 is closed, the locking portion 26 and the hook piece 4a are engaged and disengaged.

In this hair iron, when the plug of the power cord 29 (not shown) is inserted into an outlet (not shown) and the power switch 21 is turned on, the pilot lamp 22 lights up and at the same time, power is supplied to the PTC heater 9 and heat is generated. When in use, hold the first holder 1 and the second holder 2 in one hand so that the hair press plate 4 comes into contact with the heating rod 3,
Slide the lock button 24 to lock the locking portion 26 in the hook hole 4b of the hook piece 4a. When the heating rod 3 reaches a predetermined temperature, the lock button 24 is released and the first holder 1 and the second holder 2 are released by the restoring action of the spring 5.

In this hair iron, since the hair press plate 4 is made of metal, hair can be strongly and reliably held together with the heating rod 3, and a hook piece 4a for locking is formed by bending or cutting and raising the base of the hair press plate 4. Because of this structure, the number of parts does not increase, and the metal elasticity prevents plastic deformation from being forced to open the first holder 1 and the second holder 2, and from repeated locking and opening, making it durable. , also lock button 24
Even if the first holder 1 and the second holder 2 are closed with the hook set in the locked position, the hook 26 is retained by the latching portion 26 due to the bending of the hook 4a.
And the hook piece 4a will not be destroyed. In this respect, as shown in Fig. 6, the plastic cover main body 3
Compared to a structure in which a plastic hook 31'a is integrally formed on 1', it is superior in terms of durability and breakage.

As mentioned above, the hair iron of this invention is
a first holder having a heating rod at its tip; a second holder having a metal hair press plate facing the heating rod at its tip; and rear ends of the first and second holders. a connecting means that rotatably connects the first and second holders to each other and urges the first and second holders to open with a spring; a metal hook formed at the base of the hair press plate; Since the lock button is provided with a locking portion that is slidably provided and that locks on the hook piece when the first and second holders are in the closed state, the following effects are achieved.

In other words, the first
Since the holder and the second holder can be locked in the closed state, there is no need for a large storage space when storing the hair iron, and the hair is not pinched between the heating rod and the hair press plate when winding the hair. It is easy to use because it can be locked in place and the hair can be wrapped around it. In addition, since the hair presser plate can be heated with the heating rod in the locked state, the hair presser plate can be easily heated. Furthermore, since a hook piece is formed at the base of the hair presser plate, and a locking portion that locks on the hook piece is formed on the first holder, the number of parts does not increase and the locking means can be configured easily. In addition, the locking button does not get in the way of hair wrapping, so it is easy to operate, and since the hooking piece is made of metal, it is durable against excessive force and repeated locking.
