[0002] A fingerprint key is a biometric identification technology that unlocks a device by using the pre-entered fingerprint information. The fingerprint key uses the user's fingerprint information for identity verification, thus realizing the unlocking or other security operations of the device. This technology is based on the fact that each person's fingerprint is unique, and the skin patterns, including fingerprints, are different in patterns, breakpoints, and intersection points, showing uniqueness and remaining unchanged throughout life. In addition to unlocking the device, the core function of the fingerprint key also includes security and privacy protection, such as scanning and identification in the payment environment on a mobile phone.
[0003] In the prior art, the new ring light structure for collecting fingerprint keys is not convenient for fixing the fingerprint key, and at the same time, the position of the fingerprint key cannot be adjusted to cooperate with the ring light structure for collection. For this reason, we propose a new ring light structure for collecting fingerprint keys. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a new ring light structure for collecting fingerprint keys, so as to solve the problems that the new ring light structure for collecting fingerprint keys in the above background technique is not convenient for fixing the fingerprint key and cannot adjust the position of the fingerprint key to cooperate with the ring light structure for collection.
[0005] To achieve the above purpose, the utility model provides the following technical scheme: A new ring light structure for collecting fingerprint keys, including a base and a clamping mechanism. The clamping mechanism includes a mounting frame. The mounting frame is movably connected with a placement frame through a sliding groove and a slider. The bottom of the placement frame is fixedly installed with an electric telescopic rod. The placement frame is movably connected with a clamping piece through a slot and a strong spring.
[0006] As a preferred scheme, an installation groove is opened at a position close to the left side on the upper surface of the base, and a telescopic groove is opened inside the right side of the base.
[0007] As a preferred scheme, the bottom of the mounting frame is fixedly installed at a position close to the left side on the upper surface of the base. The sliding groove is opened inside the mounting frame. The slider is slidably connected with the sliding groove. The slider is fixedly connected with the placement frame. The lower end of the electric telescopic rod is fixedly installed inside the installation groove.
[0008] As a preferred scheme, the slot is opened inside the placement frame. One end of the strong spring is fixedly installed inside the slot. The clamping piece is fixedly installed at the other end of the strong spring.
[0009] As a preferred solution, a ring light mechanism is provided on the right side of the base. The ring light mechanism includes a frame. A moving rod is fixedly installed on the left side of the frame. The moving rod is inserted into the inside of the telescopic groove. A spherical seat is fixedly installed at a position near the back on the left side of the frame. An adjusting spherical member is rotatably connected inside the spherical seat. A light-emitting body is fixedly installed at the outer end of the adjusting spherical member.
[0010] As a preferred solution, a photodiode, an image collector, and an image processor are fixedly installed at a position near the front on the left side of the frame.
[0011] The technical effects and advantages of the present utility model are as follows:

Specific embodiments
[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment 1
[0021] Please refer to the attached Figure 1 - attached Figure 5 , a novel ring light structure for collecting fingerprint keys, including a base 1 and a clamping mechanism 4. The clamping mechanism 4 includes a mounting frame 401. The mounting frame 401 is movably connected to a placement rack 403 through a sliding slot 402 and a slider 404. The bottom of the placement rack 403 is fixedly installed with an electric telescopic rod 405. The placement rack 403 is movably connected to a clamping piece 408 through a slot 406 and a strong spring 407. An installation slot 3 is opened at a position near the left side on the upper surface of the base 1, and a telescopic slot 2 is opened inside the right side of the base 1. The bottom of the mounting frame 401 is fixedly installed at a position near the left side on the upper surface of the base 1. The sliding slot 402 is opened inside the mounting frame 401. The slider 404 is slidably connected to the sliding slot 402, and the slider 404 is fixedly connected to the placement rack 403. The lower end of the electric telescopic rod 405 is fixedly installed inside the installation slot 3. The slot 406 is opened inside the placement rack 403. One end of the strong spring 407 is fixedly installed inside the slot 406, and the clamping piece 408 is fixedly installed at the other end of the strong spring 407.
[0022] Both ends of the fingerprint key are placed on the surface of the placement rack 403. Through the contraction of the strong spring 407, the inner surface of the clamping piece 408 will clamp both ends of the fingerprint key, and the central part of the fingerprint key will not be blocked, and the installation and disassembly are both convenient and fast.
[0023] Specifically, through the expansion and contraction of the powerful spring 407, the fingerprint key to be collected can be fixed on the front of the placement rack 403, facing the ring light mechanism 5. Through the expansion and contraction of the electric telescopic rod 405 and the sliding of the slider 404 in the sliding groove 402, the fingerprint key can be adjusted to an appropriate height, facilitating the ring light mechanism 5 to collect data and increasing the usage range of the entire ring light structure. Embodiment 2
[0024] Please refer to the appendix Figure 1 , appendix Figure 2 and appendix Figure 5 , and on the basis of Embodiment 1, it is further obtained that a ring light mechanism 5 is provided on the right side of the base 1. The ring light mechanism 5 includes a frame 501. A moving rod 502 is fixedly installed on the left side of the frame 501. The moving rod 502 is inserted into the inside of the telescopic groove 2. A spherical seat 503 is fixedly installed at a position near the back on the left side of the frame 501. An adjusting spherical member 504 is rotatably connected inside the spherical seat 503. A light-emitting body 505 is fixedly installed at the outer end of the adjusting spherical member 504. A photodiode 506, an image collector 507, and an image processor 508 are fixedly installed at a position near the front on the left side of the frame 501.
[0025] The light-emitting body 505 can be an LED lamp or other objects that can emit a stable light source. There is damping in the rotation of the adjusting spherical member 504 in the spherical seat 503, and it will remain stationary after manual adjustment, so the angle of the light-emitting body 505 will not change automatically.
[0026] Specifically, by rotating the adjusting spherical member 504 along the spherical seat 503, the angle of the light-emitting body 505 is adjusted to face the fingerprint key to be collected, and then light is emitted. The light will irradiate the raised and sunken parts of the fingerprint, and then reflection and scattering will occur. The raised part will reflect more light, while the sunken part will scatter light. The photodiode 506 receives the reflected and scattered light, and the image collector 507 converts the received light into an electrical signal, and through the image processor 508, it is converted into a fingerprint image for processing and analysis.
[0027] Working principle of the present utility model: The present utility model is a novel annular light structure for collecting fingerprint keys. First, pull the clamping member 408, place both ends of the fingerprint key to be collected on the placement rack 403, and then release the clamping member 408, so that the strong spring 407 contracts in the slot 406, and the clamping member 408 clamps both ends of the fingerprint key. Subsequently, through the telescoping of the electric telescopic rod 405, the slider 404 slides in the sliding slot 402 to adjust the fingerprint key to an appropriate height. The frame 501 moves slowly towards the base 1 through the movement of the moving rod 502 in the telescopic slot 2 and stops at an appropriate position. Then, by adjusting the rotation of the spherical member 504 in the spherical seat 503, the light-emitting body 505 is aligned with the fingerprint key, and then emits light. The light will irradiate the raised and sunken parts of the fingerprint, and then reflection and scattering will occur. The raised part will reflect more light, while the sunken part will scatter light. The photodiode 506 receives the reflected and scattered light, and the image collector 507 converts the received light into an electrical signal, and the image processor 508 converts it into a fingerprint image for processing and analysis.
[0028] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
