[0021] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0022] like Figure 1-2 As shown, a multi-purpose lens holder includes a lens portion 10 and a mounting portion 20, wherein the mounting portions 20 are two and are symmetrically distributed on both sides of the lens portion 10, wherein a square hole 11 is provided in the lens portion 10, wherein a first lens placement groove 12 and a third lens placement groove 14 are provided on both sides of the square hole 11, and a mounting hole module is formed on the mounting portion 20. The lens portion 10 and the mounting portion 20 are integrally formed by injection molding of a plastic material.

[0023] Among them, the square hole 11 is set at the center of the lens part 10, and two lenses of different specifications can be configured on both sides of the square hole 11, and the lenses of different specifications are respectively installed in the first lens placement groove 12 and the third lens placement groove 14. When in use, the square hole 11 can play a role of filtering light, filtering out the stray light outside the instrument, thereby enhancing the overall performance of the instrument. The mounting part 20 is set on both sides of the lens part 10, and different holes can be opened on the mounting part 20 to cope with different working conditions, so that the lens holder of the present application can be flexibly adapted to different instruments.

[0024] Furthermore, in order to enable the lens holder of the present application to cope with the needs of lenses of multiple sizes, a second lens placement groove 13 is provided on the outer side of the first lens placement groove 12, and a fourth lens placement groove 15 is provided on the outer side of the third lens placement groove 14. Among them, the first lens placement groove 12 has the same shape as the third lens placement groove 14, and the second lens placement groove 13 has the same shape as the fourth lens placement groove 15. Providing multiple lens placement grooves can allow the lens holder to accommodate more than two lenses of different diameters, so that more than two lenses can be used in combination. If it is necessary to cope with lenses of more sizes, lens placement grooves can continue to be provided on the outer side of the second lens placement groove 13 or the fourth lens placement groove 15. It should be noted that in the present application, the outer side here refers to the side away from the square hole 11.

[0025] Specifically, for example, the first lens placement groove 12 and the third lens placement groove 14 are both annular grooves, and the inner diameter of the first lens placement groove 12 is larger than the inner diameter of the third lens placement groove 14. In this way, a large-sized lens can be installed in the first placement groove, and a small-sized lens can be installed in the third placement groove, and lenses of different specifications can be selected according to different instrument requirements, which fully reflects the universality of the lens holder of the present application.

[0026] In order to make the lens holder of the present application applicable to a variety of installation scenarios, the mounting hole module may include a waist-shaped hole 22 and a hexagonal hole 21, and the waist-shaped hole 22 and the hexagonal hole 21 are respectively arranged on the front and back of the mounting portion 20. Among them, the waist-shaped hole 22 or the hexagonal hole 21 is a countersunk hole. In addition, a round hole 23 is formed between the waist-shaped hole 22 and the lens portion 10. The round hole 23 is a through hole. By opening different types of mounting holes on the mounting portion 20, the lens holder can be fixed with different fasteners such as latches and hexagonal screws, thereby further increasing the adaptability of the lens holder of the present application.

[0027] Specifically, the two round holes 23 are used for fixed installation, the two waist-shaped holes 22 are used for positions that need to be adjusted, and the hexagonal hole 21 is convenient for operators to operate, and the nut will not fall off during the installation process.

[0028] When using, first install the required lens into the appropriate lens installation groove, then assemble the lens seat and the lens barrel, and finally adjust the lens seat to a suitable position for fixed installation according to the structure inside the instrument.
