[0021] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be noted that the following examples are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. Similarly, the following examples are only partial embodiments of the present invention and are not intended to be exhaustive. All other embodiments derived by persons of ordinary skill in the art without inventive effort are intended to fall within the scope of protection of the present invention.

However, it can be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments, and may be combined with each other without conflict.
[0023] In the following description of the present invention, the terms "first\second\third" involved are merely used to distinguish similar objects and do not represent a specific ordering of the objects. It can be understood that "first\second\third" can be interchanged with a specific order or sequence where permitted, so that the embodiments of the present invention described herein can be implemented in an order other than that illustrated or described herein.
[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the field of the present invention. The terms used herein are only for the purpose of describing the embodiments of the present invention and are not intended to limit the present invention.
[0025] The following is a detailed description of the embodiments. It should be noted that the serial numbers of the following embodiments do not limit the preferred order of the embodiments. The utility model provides a clamping structure for replaceable lenses.
[0026] Figure 1 A cross-sectional view of a clamping structure for replaceable lenses provided in an embodiment of the present utility model; Figure 2 This is a front view of the clamping structure of the replaceable lens provided by the embodiment of the present invention. Figure 1 and Figure 2 The clamping structure of the replaceable lens provided by the utility model is described in detail.
[0027] The interchangeable lens clamping system provided in this embodiment of the utility model is primarily applicable to optical paths in the laser field, where different optical paths can be obtained by replacing lenses. The clamping structure provided in this embodiment of the utility model mainly comprises two major parts: an optical path body 10 and a lens frame 20. The optical path body 10 is primarily used to emit light, and the lens frame 20 is provided with a lens 201. The light emitted by the optical path body 10 is directed toward the lens 201. Different lenses 201 perform different processing on the light, such as refraction or reflection, to obtain different optical paths.
[0028] Please refer to Figure 1 and Figure 2 A groove structure is formed on the optical path body 10, and the mirror frame 20 is arranged in the groove structure of the optical path body 10; and the mirror frame 20 needs to be fixedly connected to the optical path body 10 to avoid displacement between the mirror frame 20 and the optical path body 10 in the working state, resulting in deviation of the optical path. Therefore, the mirror frame 20 can be fixedly connected to the bottom surface of the groove structure to achieve connection with the optical path body 10; wherein, the bottom surface of the groove structure refers to the inner surface of the groove structure.
[0029] exist Figure 1 Figure 2 In the illustrated embodiment, the clamping structure further includes a wedge-shaped structure 30, which is positioned above the frame 20 and in close contact with the frame 20. The frame 20 is then clamped between the groove structure and the wedge-shaped structure 30. Because the wedge-shaped structure 30 is positioned above the groove structure (or above the frame 20), the groove structure forms a highly defined accommodation space, and the entire frame 20 is positioned within the groove structure. The wedge-shaped structure 30 is in close contact with the upper surface of the frame 20, and the lower surface of the frame 20 is fixedly connected to the optical path body 10 (or the groove structure). This arrangement ensures that the position of the frame 20 is fixed and not easily displaced, thereby ensuring the consistency of the position of the frame 20 during each clamping, without the need to readjust the optical path.
[0030] Specifically, a storage space is formed within the frame 20, and the lens 201 is disposed within the storage space to process light from the optical path body 10. In an embodiment of the present invention, an opening is also formed in the upper surface of the frame 20. This opening is connected to the storage space, but the area of the opening is smaller than the vertical cross-sectional area of the storage space. When the lens 201 is disposed within the storage space, the area of the lens 201 must be larger than the area of the opening (and typically also smaller than the vertical cross-sectional area of the storage space, otherwise the lens cannot be placed within the storage space). This arrangement ensures that when the lens 201 is placed within the storage space, it can be blocked by a portion of the structure on the upper surface of the frame 20 and cannot escape from the storage space. Furthermore, the wedge-shaped structure can be in close contact with the upper surface of the frame without directly contacting the lens 201 and causing damage to the lens.
[0031] In this embodiment of the present invention, the frame 20 also includes an elastic washer 202 and a threaded pressure ring 203. The elastic washer 202 is positioned below the lens, and the lens 201 is typically positioned within the elastic washer 202 to secure and protect the lens 201. The threaded pressure ring 203 is positioned below the elastic washer 202 to secure the elastic washer 202 and secure it to the frame 20. This design not only facilitates lens installation and removal but also ensures the stability of the lens in the frame. Furthermore, the elastic washer can accommodate lenses of varying thicknesses while maintaining a good seal.
[0032] In an embodiment of the present invention, a first screw hole is formed on a side surface of the frame 20 perpendicular to the bottom surface of the groove structure. The interchangeable lens mounting structure further includes a first screw 401, which is inserted into the first screw hole to securely connect the frame 20 to the optical path body 10. Specifically, the first screw 401 applies downward pressure to the frame 20 during insertion, thereby securing the frame 20. Positioning the first screw hole on the side of the frame 20 also facilitates later removal of the first screw and frame 20. In this case, the length of the first screw hole 501 needs to be less than the difference in thickness between the side surface of the frame 20 and the receiving space. In other words, the first screw hole 501 cannot penetrate the thickness of the side of the frame 20 to avoid interfering with the lens 201. In other embodiments, the first screw hole can also be positioned on the top surface of the frame 20. In this case, when the first screw 401 is inserted into the first screw hole, pressure can also be applied to the top surface of the frame 20 to secure the frame 20 to the optical path body 10. In this embodiment, the length of the first screw hole can generally be greater than or equal to the thickness of the lens frame 20 , that is, the first screw can simultaneously pass through the lens frame 20 and be partially embedded in the optical path body 10 .
[0033] Please refer to Figure 1 and Figure 2 The wedge-shaped structure provided in the embodiment of the present invention is further formed with a second screw hole, and the clamping structure for the interchangeable lens further includes a second screw 402, which is embedded in the second screw hole. In the embodiment of the present invention, when the second screw 402 is embedded in the second screw hole, the second screw applies downward pressure to the wedge-shaped structure, causing the wedge-shaped structure to be pressed against the upper surface of the frame 20. At the same time, this pressure also causes the frame 20 to be further pressed into the groove structure. Under the combined action of the first screw, the first screw hole, the second screw, and the second screw hole, the frame 20 is tightly clamped between the optical path body 10 and the wedge-shaped structure 30; at this time, the position of the wedge structure 30 is determined and fixed.
[0034] It should be noted that, although the clamping structure provided by the present invention still requires the frame to be disassembled and then the lenses on the frame to be replaced, and then the new frame (including the new lenses) to be reinstalled into the clamping structure, but since the positions of the first screw 401 and the wedge-shaped structure 30 have been determined, when the new frame is reinstalled, it is only necessary to ensure that the positions of the first screw and the wedge-shaped structure remain unchanged to ensure that the newly installed lenses will not affect the optical path. Therefore, even if the lenses are replaced, there is no need to readjust the optical path, thereby ensuring the consistency of each clamping.
[0035] In the aforementioned embodiment, the height of the frame 20 is usually also smaller than the height of the groove structure, that is, the frame 20 needs to be embedded in the groove structure to prevent other modules in the clamping structure from damaging the lenses in the frame and affecting the optical path.
[0036] The present invention further provides a light path generating device, which includes a clamping structure for replaceable lenses as described in any one of the above items. Different light paths can be generated by utilizing the clamping structure for replaceable lenses.
[0037] In the above embodiments, the description of each embodiment has its own focus. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.
