Description

Technical Field

[0001] This utility model relates to the field of nail art pen technology, and more specifically, it relates to a nail art pen with switchable drill bit. Background Technology

[0002] In nail art, setting rhinestones, pearls, metal embellishments, and other decorative elements (collectively known as "dotting") is a key technique for enhancing the sophistication, glamour, and three-dimensionality of nail art. Whether it's a simple single dotting or a complex pattern arrangement, accurately and securely attaching the embellishments to the nail surface is a core skill that nail technicians must master. The efficiency and precision of dotting directly affect the overall quality and aesthetics of the nail art, as well as the nail technician's work efficiency.

[0003] Existing interchangeable drill bit nail pens typically use a detachable design between the pen barrel and the tip, allowing for the replacement of different sized tips via screw-on, snap-on, or insertion methods. Changing tips requires the nail technician to use both hands, unscrewing the old tip and screwing on the new one. This process is particularly cumbersome in glue-containing work environments, and the tiny removed tips are easily lost or attract dust, affecting adhesion.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a nail art pen with a switchable drill bit. When it is necessary to switch drill bits, the pen holder with the desired drill bit can be directly removed and installed at the front. This process can be operated with one hand, and the replaced drill bit will enter the insertion slot without getting dusty and affecting the adhesiveness.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a switchable drill bit nail pen includes several pen holders, each of which has a connecting block fixedly connected to its top side, and a drill bit fixedly connected to the connecting block. The diameter of the spherical top of each drill bit is different. Each pen holder has an insertion groove on its bottom side for inserting the connecting block and the drill bit. The connecting block on the top side of the pen holder can be detachably snapped into the connecting groove on the bottom side of another pen holder.

[0007] The present invention is further configured such that the outer wall of the pen holder is cut with a gripping surface.

[0008] The present invention is further configured such that: the connecting block is a D-shaped cylinder, and a limiting block is fixedly connected in the insertion groove.

[0009] The present invention is further configured such that: the end of the limiting block near the bottom of the pen holder is 1mm-2mm away from the bottom of the pen holder, and the end of the limiting block near the bottom of the pen holder is cut with an insertion bevel.

[0010] The present invention is further configured such that the limiting block is arranged parallel to the gripping plane.

[0011] The present invention is further configured such that the number of pen holders is 4 to 6.

[0012] In summary, this utility model has the following beneficial effects: when it is necessary to switch drill bits, the pen holder with the required drill bit can be directly removed and installed at the front. This process can be operated with one hand, and the replaced drill bit will enter the insertion groove, which will not be contaminated with dust and affect the adhesiveness. In addition, the insertion slope is provided, making it easier and faster to connect pen holders in pairs. Attached Figure Description

[0015] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0016] A type of nail art pen with switchable drill bit dispenser, such as Figures 1-4 As shown, the device includes several pen holders 1, each with a connecting block 2 fixedly connected to its top side. A drill bit 3 is fixedly connected to the connecting block 2. The diameter of the spherical top of each drill bit 3 is different. Each pen holder 1 has an insertion groove 4 on its bottom side for inserting the connecting block 2 and the drill bit 3. The connecting block 2 on the top side of the pen holder 1 can be detachably snapped into the connecting groove on the bottom side of another pen holder 1. When it is necessary to replace the drill bit 3, the front pen holder 1 connected to the required drill bit 3 can be removed from the pen holder 1 connected to the required drill bit 3. Then, the connecting block 2 on the top pen holder 1 can be placed into the insertion groove 4 of the tail pen holder 1 to complete the replacement. This process can be operated with one hand, and the replaced drill bit 3 will enter the insertion groove 4 without being contaminated with dust, which will affect the adhesiveness.

[0017] like Figures 1-3 As shown, the outer wall of the pen holder 1 is cut with a gripping surface 5, which makes it easier to hold the nail art pen, prevents the nail art pen from rotating when dotting, and improves the working stability of the nail art pen.

[0018] like Figures 1-4As shown, the connecting block 2 is a D-shaped cylinder, and a limiting block 6 is fixedly connected inside the insertion groove 4. The limiting block 6 and the insertion groove 4 can form a D-shaped insertion groove 4 that is compatible with the connecting block 2, so as to prevent the pen holder 1, except for the holding pen holder 1, from falling off due to rotation during the point drilling, thus affecting the point drilling.

[0019] like Figure 2 , Figure 4 As shown, the end of the limiting block 6 near the bottom of the pen holder 1 is 1mm-2mm away from the bottom of the pen holder 1. The end of the limiting block 6 near the bottom of the pen holder 1 is cut with an insertion slope 7. When connecting two pen holders 1, the connecting block 2 of the pen holder 1 can be first placed into the insertion groove 4 of the other pen holder 1, and then the pen holder 1 can be pushed and rotated to quickly connect the two pen holders 1. The insertion slope 7 can further accelerate the connection and prevent the pen holder 1 from rotating too far.

[0020] like Figure 2 As shown, the limiting block 6 is set parallel to the gripping plane 5, which can effectively identify the position of the limiting block 6 to facilitate quick connection between pen holders 1.

[0021] like Figure 1 , Figure 3 As shown, there are 4 to 6 pen holders 1. After the pen holders 1 are stacked and connected in the vertical direction, the stacked state of 4 to 6 pen holders 1 will be almost the same length as the other working pens. At this time, after putting the nail art pen into the tool pen storage box, it will be easier to find and take it out.

[0022] Working principle: When it is necessary to replace the drill bit 3, the front end of the pen holder 1 connected to the required drill bit 3 can be removed from the pen holder 1 connected to the required drill bit 3. Then, the top pen holder 1 and the connecting block 2 can be placed into the insertion groove 4 of the tail pen holder 1 to complete the switching. This process can be operated with one hand, and the replaced drill bit 3 will enter the insertion groove 4 without being contaminated with dust and affecting the adhesiveness.

[0023] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
