Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

Referring to fig. 1-9, a middle-end hair straightener stretching structure comprises a body upper shell 1, a body lower shell 2, an upper PTC3, a lower PTC4, a body upper bracket 5, a body lower bracket 6, a handle 8 and an AC power line 19, wherein a torsion spring structure 7 is arranged at the positions of the body upper shell 1 and the body lower shell 2 close to the handle 8, the torsion spring structure 7 comprises torsion springs 21 and torsion spring fixing plates 22, two adjacent torsion spring fixing plates 22 are provided with torsion spring grooves which are centrosymmetric, the torsion springs 21 are arranged in the torsion spring grooves, the two adjacent torsion spring fixing plates 22 are connected through the torsion springs 21, and the torsion springs 21 are unfolded to be in a shape of Chinese character ji; the ends of the upper body shell 1 and the lower body shell 2 far away from the handle 8 are respectively provided with a front body cover B12 and a front body cover A11.

A potentiometer with a certain size is arranged in the handle 8, the output shaft end of the potentiometer is connected with a potentiometer gear 17, and a potentiometer driving piece is arranged in the handle 8.

Internal teeth 18 are fully distributed on the inner wall of the potentiometer driving piece, a clamping groove 20 matched with the handle 8 is formed in the outer wall of the potentiometer driving piece, a handle assembly inner guide buckle 14 is fixed on the inner wall of the handle 8, the handle assembly inner guide buckle 14 extends into the clamping groove 20 to be arranged, and the internal teeth 18 are meshed with the potentiometer gear 17.

When not in use, the upper and lower clamping plates are combined and pushed relatively to the handle to achieve the locking effect.

The upper shell 1 of the machine body is provided with a digital display 9 and a PCBA component 10.

A telescopic lock 23 is provided at one side of the torsion spring structure 7.

The working principle is as follows: the upper machine body and the lower machine body are automatically separated under the action of the elasticity of the torsion spring 21, so that the upper clamping plate and the lower clamping plate of the hair straightener can be automatically separated, and the upper clamping plate and the lower clamping plate can be kneaded by hands to open and close in the using process so as to be used for the hair straightening function. When the hair straightener is used, the handle 8 is rotated, the guide buckle 14 in the handle assembly on the inner wall of the handle 8 rotates along with the rotation, so that the guide buckle 14 in the handle assembly drives the potentiometer driving piece to rotate, the inner teeth 18 on the inner wall of the potentiometer driving piece rotate along with the rotation, the inner teeth 18 are meshed with the potentiometer gear 17, the inner teeth 18 rotate to drive the potentiometer gear 17 to rotate along with the rotation, the potentiometer gear 17 rotates to drive the mechanism in the potentiometer to rotate, the potentiometer has a switch function, and the switch of the potentiometer can be turned on and off while the handle 8 rotates, so that people can conveniently use the hair straightener; when the switch of the potentiometer is turned on, the main digital display 9 is also lightened to prompt an effective use state, and in addition, the rotation angles of the handle 8 are different, so that different temperatures can be controlled and realized.

When using up, close hair straightener lower clamping plate, wholly impel handle 8 position, torsional spring structure 7 can reach 23 positions of lock system and reach the locking effect, otherwise, pull out handle 8 with the splint subassembly when using, torsional spring structure 7 can reach the purpose of unblanking with the separation of flexible lock system 23.

According to the middle-end hair straightener telescopic structure, the flicking angle of the hair straightener is flicked by the force of the torsion spring 21, but the angle is positioned by the front die casting and the rear die casting, and the angle limit is positioned by hardware, so that the two clamping plates are outwards opened to have better strength; the torsion spring structure is adopted for springing, and the torsion spring 21 can adjust the angle to adjust the force for opening the clamping plate; the torsional spring structure can save space for there is enough space to do splint both sides pile up into and bounce off the structural design, can reserve sufficient line space of walking, and when not using, the lower plate is closed, pushes away relatively with handle 8 and reaches the lock and acts on and avoids placing the tong with pushing away the system lock.
