[0026] like Figures 1 to 8 As shown, the portable hair straightener of this utility model includes: a base frame 1 having a first end 11 and a second end 12, the first end 11 being hinged to an upper clamping plate 2 and a lower clamping plate 3, the second end 12 being hinged to a torsion spring 4, the two ends of the torsion spring 4 being connected to the upper clamping plate 2 and the lower clamping plate 3 respectively; and a locking unit disposed on the base frame 1, the locking unit being synchronously connected to the upper clamping plate 2 and the lower clamping plate 3, and being able to lock or unlock the upper clamping plate 2 and the lower clamping plate 3 according to the user's selection.

[0027] See Figures 1 to 5, the base 1 has opposite first end 11 and second end 12, the first end 11 of the base 1 is hinged with the upper clamping plate 2 and the lower clamping plate 3 respectively, the part of the upper clamping plate 2 and the lower clamping plate 3 close to the first end 11 of the base 1 can shield the base 1, so as to facilitate the user to take the straightener, the second end 12 of the base 1 is installed with the torsion spring 4 through the rod body, the two ends of the torsion spring 4 are connected at the middle position of the upper clamping plate 2 and the middle position of the lower clamping plate 3 respectively, the position of the upper clamping plate 2 and the lower clamping plate 3 is limited by the torsion spring 4, so that the upper clamping plate 2 and the lower clamping plate 3 can only be opened to a predetermined angle, and when the upper clamping plate 2 and the lower clamping plate 3 need to be opened, the upper clamping plate 2 and the lower clamping plate 3 can be smoothly opened to the predetermined angle by the elastic force of the torsion spring 4, thereby improving the use effect of the user; the base 1 is further provided with a circuit board for controlling the opening and closing of the heating unit.

[0028] Referring to Figure 3 , the locking unit is arranged on the base 1 and can slide to unlock the upper clamping plate 2 and the lower clamping plate 3, so that the upper clamping plate 2 and the lower clamping plate 3 can be elastically opened and closed by the torsion spring 4, when the locking unit locks the upper clamping plate 2 and the lower clamping plate 3, the upper clamping plate 2 and the lower clamping plate 3 are in a closed state, and the torsion spring 4 stores elastic potential energy.

[0029] Specifically, when the user uses the straightener of the present application, first, the locking unit is controlled to unlock the upper clamping plate 2 and the lower clamping plate 3, the torsion spring 4 releases the elastic potential energy to naturally open the upper clamping plate 2 and the lower clamping plate 3, then the straightening or curling operation is performed by clamping the user's hair with the upper clamping plate 2 and the lower clamping plate 3, after the user finishes straightening, the upper clamping plate 2 and the lower clamping plate 3 are pressed to close, and then the locking unit is used to lock the upper clamping plate 2 and the lower clamping plate 3, which has the characteristics of simple locking structure and convenient operation, and after the upper clamping plate 2 and the lower clamping plate 3 are locked and closed by the locking unit, the space occupied by the straightener of the present application can be further reduced, which is convenient for the user to carry.

[0030] In one or more embodiments, the locking unit at least includes a clamping plate 5 slidingly arranged on the base 1 and having a first clamping buckle 51 and a second clamping buckle 52 respectively on the two sides thereof towards the upper clamping plate 2 and the lower clamping plate 3, a first protrusion 21 formed in the inner side of the upper clamping plate 2, and a second protrusion 31 formed in the inner side of the lower clamping plate 3.

[0031] Referring to Figures 5 to 8The clamping plate 5 has a first clamping buckle 51 on the side facing the upper clamping plate 2 and a second clamping buckle 52 on the side facing the lower clamping plate 3. The first clamping buckle 51 extends towards the first protrusion 21, and the second clamping buckle 52 extends towards the second protrusion 31. When the upper clamping plate 2 and the lower clamping plate 3 are closed, the first protrusion 21 on the inner side of the upper clamping plate 2 is located on the inner side of the first clamping buckle 51, and the second protrusion 31 on the inner side of the lower clamping plate 3 is located on the inner side of the second clamping buckle 52. When it is necessary to lock the upper clamping plate 2 and the lower clamping plate 3, the upper clamping plate 2 and the lower clamping plate 3 are first closed, and then the clamping plate 5 is pushed upwards so that the first clamping buckle 51 of the clamping plate 5 is located on the outer side of the first protrusion 21 and the second clamping buckle 52 of the clamping plate 5 is located on the outer side of the second protrusion 31. Then, the pressing on the upper clamping plate 2 and the lower clamping plate 3 is released, and the upper clamping plate 2 and the lower clamping plate 3 have a tendency to be opened under the action of the torsion spring 4, so that the first protrusion 21 of the upper clamping plate 2 abuts against the first clamping buckle 51 of the clamping plate 5 and the second protrusion 31 of the lower clamping plate 3 abuts against the second clamping buckle 52 of the clamping plate 5, thereby achieving the locking of the upper clamping plate 2 and the lower clamping plate 3. When it is necessary to unlock the upper clamping plate 2 and the lower clamping plate 3, the clamping plate 5 is pushed downwards so that the first clamping buckle 51 of the clamping plate 5 exits the outer side of the first protrusion 21 and the second clamping buckle 52 of the clamping plate 5 exits the outer side of the second protrusion 31. The first clamping buckle 51 no longer limits the position of the first protrusion 21, and the second clamping buckle 52 no longer limits the position of the second protrusion 31. At this time, the upper clamping plate 2 and the lower clamping plate 3 are pushed away from each other under the action of the torsion spring 4, thereby achieving the unlocking of the upper clamping plate 2 and the lower clamping plate 3. The straightening iron has the characteristics of simple structure and convenient operation, and can be in a closed state when not in use, thereby being convenient to store and carry.

[0032] In one or more embodiments, the bottom surface of the clamping plate 5 is formed with an arc-shaped clamping portion 53, the base frame 1 has a bearing portion 13 abutting against the clamping portion 53, and the bearing portion 13 is formed with a limiting clamping groove 131. When the first clamping buckle 51 clamps the first protrusion 21 of the upper clamping plate 2 and the second clamping buckle 52 clamps the second protrusion 31 of the lower clamping plate 3, the clamping portion 53 is located in the limiting clamping groove 131. The clamping plate 5 is made of hard plastic or elastic metal.

[0033] Referring to Figures 6 to 8, the arc-shaped clamping portion 53 of the clamping plate 5 is in a semi-cylindrical structure, and the bearing portion 13 of the base frame 1 is provided with a semi-cylindrical limiting clamping groove 131; when the upper clamping plate 2 is locked by the first clamping buckle 51 of the clamping plate 5 and the lower clamping plate 3 is locked by the second clamping buckle 52 of the clamping plate 5, the arc-shaped clamping portion 53 on the bottom surface of the clamping plate 5 enters the limiting clamping groove 131 on the bearing portion 13 of the base frame 1; at this time, since the clamping plate 5 is made of hard plastic or elastic metal, and before the clamping portion 53 of the clamping plate 5 enters the limiting clamping groove 131, the clamping portion 53 is in a deformed state due to being stopped by the bearing portion 13 of the base frame 1, and after the clamping portion 53 of the clamping plate 5 enters the limiting clamping groove 131, the clamping portion 53 of the clamping plate 5 is no longer stopped by the bearing portion 13 of the base frame 1, and the clamping plate 5 returns to its original state; at this time, the user can obviously feel the jerk brought by the clamping plate 5, reminding the user to push the clamping plate 5 into or out of the limiting clamping groove 131, thereby improving the user experience and ensuring the clamping effect of the upper clamping plate 2 and the lower clamping plate 3.

[0034] It should be noted that the clamping plate 5 made of hard plastic or elastic metal can have certain elastic deformation, thereby reducing the weight of the clamping plate 5 and prolonging the service life of the clamping plate 5.

[0035] In one or more embodiments, the limiting clamping groove 131 is in a rounded structure near the first end 11 of the base frame 1. See Figure 6 Through this arrangement, the arc-shaped clamping portion 53 entering the limiting clamping groove 131 can be more easily entered or exited, which is convenient for the user to separate the upper clamping plate 2 and the lower clamping plate 3, and has the characteristics of simple structure and convenient operation.

[0036] In one or more embodiments, the upper clamping plate 2 and the lower clamping plate 3 are jointly provided with a sliding groove 6, and the clamping plate 5 is provided with a button 7 on the top portion, and the button 7 is located in the sliding groove 6.

[0037] See Figures 1 to 3 The upper clamping plate 2 and the lower clamping plate 3 are both provided with a slot at the part corresponding to the base frame 1, the slots of the upper clamping plate 2 and the lower clamping plate 3 jointly form a sliding groove 6, and the button 7 on the top portion of the clamping plate 5 is slidingly arranged in the sliding groove 6; when the button 7 is pushed to the top portion of the sliding groove 6, the first clamping buckle 51 of the clamping plate 5 is located at the outer side of the first protrusion 21, and the second clamping buckle 52 of the clamping plate 5 is located at the outer side of the second protrusion 31, thereby limiting the position of the upper clamping plate 2 and the lower clamping plate 3 and achieving the closing of the upper clamping plate 2 and the lower clamping plate 3.

[0038] In one or more embodiments, the first buckle 51 has a first wedge surface 511 on the side which is adapted to the inner wall of the upper clamping plate 2, and the second buckle 52 has a second wedge surface 521 on the side which is adapted to the inner wall of the lower clamping plate 3. When the upper clamping plate 2 and the lower clamping plate 3 are closed, the first wedge surface 511 of the first buckle 51 is tightly attached to the inner wall of the upper clamping plate 2, and the second wedge surface 521 of the second buckle 52 is tightly attached to the inner wall of the lower clamping plate 3.

[0039] Referring to Figure 7 、 Figure 8 When the upper clamping plate 2 and the lower clamping plate 3 are closed, the first wedge surface 511 of the first buckle 51 is tightly attached to the inner wall of the upper clamping plate 2, and the second wedge surface 521 of the second buckle 52 is tightly attached to the inner wall of the lower clamping plate 3, so that the first buckle 51 and the second buckle 52 are not hindered when the user pushes the card plate 5 upward. When the first protrusion 21 of the upper clamping plate 2 is clamped by the first buckle 51 and the second protrusion 31 of the lower clamping plate 3 is clamped by the second buckle 52, the first protrusion 21 is tightly attached to the inner wall of the upper clamping plate 2, and the second protrusion 31 is tightly attached to the inner wall of the lower clamping plate 3, so that the upper clamping plate 2 and the lower clamping plate 3 can be closed more stably and will not open a small gap, avoiding foreign objects from entering between the upper clamping plate 2 and the lower clamping plate 3, and improving the use effect of the present application.
