In other words, the clamping end 311 is installed in the installation cavity 331 by swinging with the rotating end 312 as the shaft, compared with the mode that the clamping piece 31 is integrally installed in the installation cavity 331 along the hole depth direction (the direction perpendicular to the rotating axis of the connecting seat 20) of the abdicating hole 332 in a sliding manner, in the scheme, the rotating end 312 does not move along the hole depth direction of the abdicating hole 332 basically, the required moving space of the rotating end 312 in the installation cavity 331 is smaller, the occupied space of the clamping piece 31 in the installation cavity 331 can be reduced, thereby the structural compactness of the connecting seat 20 and the clamping structure can be improved, the size of the curling iron 40 can be reduced, and the clamping and the use by a user can be facilitated.

In some embodiments, the rotating shaft 71 is disposed in the mounting cavity 331, the rotating end 312 is provided with a rotating groove 314, two ends of the rotating groove 314 are disposed in a penetrating manner along an axial direction of the rotating shaft 71, the rotating end 312 is rotatably mounted on the rotating shaft 71 through the rotating groove 314, and a notch of the rotating groove 314 is located on a side of the rotating end 312 away from the connecting seat 20. Specifically, the outer circumferential surface of the rotating portion is substantially circumferentially arranged, and the rotating end 312 is substantially in a hook shape, when being installed, the rotating shaft 71 can be installed in the installation cavity 331 firstly, and then the rotating end 312 is clamped between the rotating shaft 71 and the connecting seat 20 from the notch of the rotating groove 314, so that the situation that the shaft hole and the rotating shaft 71 in the rotating portion are troublesome to position can be avoided, and the installation of the clamping piece 31 can be facilitated.

In some embodiments, a position of the inner side of the annular housing 33 corresponding to the yielding through opening 203 is provided with a limiting groove 333, the limiting groove 333 penetrates through an end surface of the annular housing 33 and a wall of the mounting cavity 331, the fastening portion 425 is convexly arranged on an outer circumferential surface of the insertion portion 421, a fastening hole 426 is formed in an end surface of the fastening portion 425 away from the heating rod 41, when the insertion portion 421 is inserted into the insertion cavity 201, the fastening portion 425 is correspondingly inserted into the limiting groove 333, and the fastening end 311 of the fastening member 31 is fastened in the fastening hole 426. So set up, the space that utilizes annular housing 33 in other words cooperates with joint portion, avoids joint portion and joint structure to occupy grafting portion 421 and the condition in grafting chamber 201 fitting space for fixing base 42 is big, be connected stably with connecting seat 20 cooperation area, and can be so that the compact structure of connecting seat 20 and joint structure, be favorable to reducing the size of curly hair stick 40, and the user of being convenient for grips the use. When the buckling parts 425 are correspondingly inserted into the limiting grooves 333, the fixing seat 42 can be effectively prevented from rotating relative to the connecting seat 20, so that the installation of the curling iron 40 is more stable.

In some embodiments, the connecting base 20 is provided with an arc-shaped groove 202 at a position corresponding to the rotating shaft 71, and the rotating end 312 is rotatably mounted in the arc-shaped groove 202. So set up, can be so that rotate the comparatively steady rotation of end 312 in arc recess 202, steady, reliable when can making joint 31 rotate reduces joint 31 trouble risk.

In some embodiments, the pressing member 32 is provided with a position-limiting buckle 321, the clamping member 31 is provided with a position-limiting buckle hole 313, and the position-limiting buckle 321 is movably clamped in the position-limiting buckle hole 313. Specifically, the length of the limiting buckle 321 is greater than the depth of the limiting buckle hole 313, so that the pressing piece 32 and the clamping piece 31 can be restrained well, and the situation that the clamping piece 31 is limited in rotation due to rigid connection of the pressing piece 32 and the clamping piece 31 can be avoided.

In some embodiments, one of the outer side surface of the insertion portion 421 and the cavity wall of the insertion cavity 201 is provided with a fool-proof rib 23, and the other one is provided with a fool-proof groove 428, wherein when the insertion portion 421 is inserted into the insertion cavity 201, the fool-proof rib 23 is inserted into the fool-proof groove 428. This facilitates the user in installing the curling iron 40 and avoids the user from being incorrectly positioned.
