Description

Technical Field

[0001] This utility model belongs to the field of nail printer technology, and specifically relates to a finger fixing device in a nail printer. Background Technology

[0002] As the nail industry continues to expand, self-service nail art has also developed rapidly with the advancement of technology. Nail printers, with their convenience and speed, have quickly become popular in the nail industry. When using a nail printer, you first need to place your finger in the printer for scanning and positioning before proceeding with the subsequent steps.

[0003] Most existing nail printers use simple finger positioning and fixing devices that simply hold the finger in place. However, during the nail art process, customers may move their fingers due to changes in body posture, leading to inaccurate positioning. Additionally, the customer's finger may deviate significantly from the original positioning of the nail printer, making it difficult to complete the nail art quickly. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a finger fixing device in a nail printer, which can quickly fix and position the finger, shortening the waiting time for nail art production.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A finger fixing device in a nail printer includes a base plate, a finger support, an adapter block, a sliding block, a guide strip, a fixing component, a fixing strap, and a limiting component. The guide strip is fixedly provided on the top of the base plate, and a sliding block is slidably connected to the guide strip. An adapter block is fixedly provided on the top of the sliding block, and a finger support is fixedly provided on the top of the adapter block.

[0007] The adapter block has a sliding groove on its side wall and a connecting component on its front side wall. The connecting component includes a T-shaped block, a sliding plate, and a retaining shaft. The T-shaped block is fixedly connected to the side wall of the adapter block. A sliding plate is provided on one side of the T-shaped block. The sliding plate has a dovetail groove inside that mates with the T-shaped block. A retaining shaft is fixedly provided on the side wall of the sliding plate. The retaining shaft is in the shape of an inverted "T".

[0008] The fixing assembly includes an ear seat, a transmission plate, and a connecting plate. The ear seat is fixedly connected to the base plate. The transmission plate is triangular in shape and is located on one side of the ear seat. One corner of the transmission plate is connected to the ear seat via a shaft. The bottom of the other corner of the transmission plate is fixedly provided with a shaft that mates with a sliding groove. The connecting plate is located on the other side of the transmission plate and is connected to the last corner of the transmission plate via a shaft. A fixing belt is connected between the connecting plates.

[0009] Preferably, the limiting component includes a bracket, a support plate, a pressing block, a spring, a transmission shaft, a drive rod, a support shaft, a connecting rod, a triangular block, a sliding rod, and a lifting block. The bracket is fixedly connected to the base plate, and the support plate is fixedly provided on the top of the bracket. A support shaft is provided in the middle of the bracket, and the drive rod is connected to the middle of the bracket through the support shaft. One end of the drive rod is connected to the transmission shaft through a shaft, and the other end of the drive rod is connected to the connecting rod through a shaft. A triangular block is fixedly connected to one end of the connecting rod. The transmission shaft passes through the support plate, and the support plate provides movement support for the transmission shaft. A pressing block is fixedly provided at the other end of the transmission shaft, and a spring is provided between the pressing block and the support plate. The sliding rod is fixedly connected to the base plate, and the lifting block is slidably connected to the sliding rod.

[0010] Preferably, the finger holder has a placement slot inside.

[0011] During use, place your finger in the placement slot and push it forward. The sliding block will slide forward with the support of the guide strip. During the forward sliding, the transmission plate will rotate forward around the ear seat with one of its corners as the fulcrum. The other corner of the transmission plate will drive the connecting plate to move downward. During the downward movement of the connecting plate, the fixing strap will gradually tighten, thus binding the finger.

[0012] Pushing it forward further, the locking shaft will pass between the two slide bars until it contacts the squeezing block. Pushing it forward again, the squeezing block will drive the transmission shaft to move backward under the action of the locking shaft. At this time, the spring will be compressed, causing the drive rod to rotate around the support shaft as the fulcrum. This will cause the connecting rod to drive the triangular block to move forward until the triangular block contacts the lifting block. As the triangular block continues to move forward, the lifting block will also continue to move upward under the action of the bracket until it contacts the locking shaft. At this point, the finger support can be limited and fixed.

[0013] When it is necessary to release the limit, push the slide upward to disengage the locking shaft from above the lifting block. Under the action of the spring, the drive rod rotates in the opposite direction to return to its original state, and the lifting block will fall back to the bottom plate under the action of gravity.

[0014] The advantages of this utility model compared with the prior art are as follows:

[0015] When a customer is getting a manicure, they place their finger in the placement slot and push it forward. As the finger slides forward, the transmission plate rotates around the ear base with one of its corners as a fulcrum. The other corner of the transmission plate drives the connecting plate to move downward. As the connecting plate moves downward, it gradually tightens the fixing strap, binding the finger and preventing it from moving during the manicure process, thus improving positioning accuracy.

[0016] The finger holder is connected to the limiting component via the connecting component on the adapter block, which allows for quick pre-positioning of the finger during the nail art process. This minimizes the deviation between the finger and the original positioning of the nail printer, thereby shortening the overall nail art process time. Attached Figure Description
