Those skilled in the art will understand the specific meanings of the above terms in the embodiments of this application based on the specific circumstances.

[0027] In the embodiments of the present application, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Furthermore, a first feature being "above," "above," and "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0028] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] See also Figures 1 to 5 As shown; The embodiment of the present application discloses a hair clip 2 pen, which is based on a writing pen and utilizes the clamping function of the pen clip to form a hair clip 2; Specifically in this embodiment, the hair clip 2 pen includes a pen body 1 and a hair clip 2, the pen body 1 includes a shell, a pen tip 102 connected to one end of the shell and a button 103 connected to the other end of the shell; the shell in this embodiment is assembled by an upper shell 100 and a lower shell 101; a connecting seat 104 extending along the length direction of the pen body 1 is provided at the end of the pen body 1 away from the pen tip 102; the connecting seat 104 is protruding and arranged on the upper On the outer wall of the housing 100; the structure of the hairpin 2 includes two hinged plates: a first plate 200 and a second plate 201, an elastic member 205 is provided between the first plate 200 and the second plate 201, the elastic member 205 makes one end of the two plates always have a relative clamping movement tendency; it can be understood that the hinge of the first plate 200 and the second plate 201 is located in the middle of the hairpin 2 and close to the button 103; when overcoming the elastic force of the elastic member 205, one end of the first plate 200 and the second plate 201 can be opened and the other end can be brought together.

[0030] In this embodiment, the first clamping plate 200 is detachably connected to the connecting base 104. That is, the hairpin 2 can be removed from the connecting base 104 of the pen body 1 and used as a hairpin 2. After use, it can be reattached to the connecting base 104 of the pen body 1 and used as a pen clip. Therefore, the hairpin 2 not only has a writing function, but also has the function of a hairpin 2 for holding hair. In addition, the hairpin 2 can be removed from the pen body 1 for use alone, avoiding the need to use the hairpin 2 together with the pen body 1 or accessories of the pen body 1. This reduces weight, makes it easier for users to wear, and prevents it from falling off due to its own weight after wearing.

[0031] Further in this embodiment, the elastic member 205 is a cylindrical coil spring, one end of which is connected to or abuts against the first clamping plate 200, and the other end is connected to or abuts against the second clamping plate 201, and the elastic member 205 is arranged on one side of the hinge point of the hairpin 2; specifically, see Figure 1 and Figure 2 As shown, a base 202 is provided on the first splint 200, and a connecting plate 203 is provided on the second splint 201, and the connecting plate 203 is rotatably connected to the base 202 via a rotating shaft 204; an elastic member 205 is provided on a side of the base 202 away from the pen tip 102, and both ends of the elastic member 205 are elastically opposed to the first splint 200 and the second splint 201 respectively.

[0032] In order to make the connection of the elastic member 205 more stable, in the above embodiment, a positioning post 206 for connecting the elastic member 205 is provided on the first clamping plate 200 and / or the second clamping plate 201. The provision of the positioning post 206 prevents the elastic member 205 from deviating, making the use of the hairpin 2 more stable.

[0033] In other embodiments, the elastic member may also be a torsion spring, that is, the torsion spring is connected to the rotating shaft on which the first clamping plate and the second clamping plate are hinged, and the two clamping feet of the torsion spring are respectively against the first clamping plate and the second clamping plate, so that one end of the first clamping plate and the second clamping plate or the end close to the pen tip always has a relative clamping movement tendency.

[0034] It is easy to understand that the first clamping plate 200 of the hairpin 2 and the connecting seat 104 of the pen body 1 are detachably connected, and can be detachably connected in the form of a snap or a movable plug. Figure 2 and Figure 3 As shown, the connecting base 104 is provided with a slot 105 along the length direction, and the first clamping plate 200 is movably inserted into the slot 105. The structure is simple, and the installation or removal of the hairpin 2 and the pen body 1 is simple and convenient.

[0035] Further in this embodiment, see Figure 2 and Figure 4 As shown, the end of the slot 105 away from the pen tip 102 extends through the end surface of the rear end of the pen body 1. An opening 106 is formed at the rear end of the pen body 1 for inserting the first clamping plate 200 into the slot 105. The rear end of the pen body 1 is rotatably connected to a rotating base 3 coaxially arranged with the pen body 1. The rotating base 3 is provided with a radially extending stopper 300 for closing or opening the opening 106. When installing the first clamping plate 200 of the hairpin 2, the rotating base 3 is first rotated to disengage the stopper 300 from the opening 106 of the slot 105. The first clamping plate 200 of the hairpin 2 is then inserted into the slot 105 through the opening 106. The rotating base 3 is then rotated in the opposite direction so that the stopper 300 on the rotating base 3 blocks or obstructs the opening 106 of the slot 105. This confines the first clamping plate 200 within the slot 105 of the connecting base 104, preventing the hairpin 2 from accidentally detaching from the connecting base 104 of the pen body 1. Similarly, when taking out the hairpin 2, the rotatable base 3 only needs to be rotated to disengage the stopper 300 on the rotatable base 3 from the opening 106 of the slot 105, and the hairpin 2 can be easily taken out of the slot 105, so the operation is very simple and convenient.

[0036] In the above embodiment, in order to more quickly remove the hairpin 2 from the pen body 1, an inwardly concave recess 302 is provided on the outer peripheral wall of the rotating base 3. When the recess 302 rotates to align with the opening 106, the opening 106 is opened. Figure 4In the illustrated state, the recess 302 is a vertical plane, serving as a rotation indicator. Therefore, when the user rotates the rotating base 3, they only need to rotate the rotating base 3 until the recess 302 is aligned with the opening 106 to fully open the opening 106, thereby making the entire hairpin 2 easier to remove or install.

[0037] In some embodiments, see Figure 3 、 Figure 4 and Figure 5 As shown, the rotating base 3 is connected with a hanging ring 301 for hanging pendants. Small ornaments, pendants, etc. can be hung on the hanging ring 301, which not only serves as a decorative pen, but also makes the rotation of the rotating base 3 more labor-saving and convenient.

[0038] It can be understood that the rotating seat 3 has an inserting portion coaxial with the pen body 1, and the inserting portion is inserted into the upper shell 100 of the pen body 1, so that the rotating seat 3 can rotate along the circumference of the pen body 1 and is axially limited on the pen body 1 to prevent the rotating seat 3 from separating from the pen body 1.

[0039] Further in this embodiment, see Figure 5 As shown, in order to make the first clamping plate 200 of the hairpin 2 and the slot 105 of the connecting seat 104 more firmly and stably inserted, and to prevent the hairpin 2 from shaking left and right relative to the connecting seat 104, positioning protrusions are provided on both side walls of the first clamping plate 200, and two positioning grooves (not shown in the figure) that match the positioning protrusions are provided on the inner side wall of the slot 105. When the first clamping plate 200 is inserted into the slot 105, the two positioning protrusions are respectively engaged in the two positioning grooves.

[0040] In some embodiments, an ornament is connected to the outer wall of the second splint 201 , so that when the hairpin 2 is removed for use, the user can connect ornaments of different shapes and colors to the outer wall of the second splint 201 , thereby increasing the interest and aesthetics of the hairpin 2 .

[0041] In some embodiments, a middle plate 207 extending along the length of the second clamping plate 201 is provided on the inner sidewall of the second clamping plate 201. The middle plate 207 is provided with teeth (not shown). The middle plate 207 is connected to the second clamping plate 201 perpendicularly to the second clamping plate 201. The teeth provide a secure and stable grip when used as a hairpin 2, and prevent the pen from falling off and thus from being lost when used as a pen holder.
