[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] Please see Figures 1 to 11 A holographic diffraction sight with a quick-release structure includes a scope body 1 and a guide rail (not shown) mounted on an external device. The scope body 1 houses a micrometer-level optical path adjustment mechanism 2. A connecting seat 3 is mounted at the bottom of the scope body 1. The connecting seat 3 has a locking part 31 that matches the guide rail, allowing it to be mounted on the guide rail. The locking part 31 has a quick-release mechanism 4 for clamping or releasing the guide rail. By providing a connecting seat 3 at the bottom of the scope body 1, and a locking part 31 on the connecting seat 3 that can connect to the guide rail, this holographic diffraction sight with a quick-release structure can be installed on any device with a pre-installed guide rail, eliminating the need for a specially designed connecting seat 3. Furthermore, the quick-release mechanism 4 on the locking part 31 allows for quick fixing and disassembly of the connecting seat 3 and the guide rail. A Picatinny rail is preferred.

[0035] Please see Figures 1 to 5 Preferably, the quick-release mechanism 4 includes a knob 41, a pressure plate 42, and a pull rod 43. One end of the pull rod 43 is connected to the pressure plate 42, and the other end of the pull rod 43 is provided with the knob 41. The guide rail is located between the knob 41 and the pressure plate 42. The knob 41 and / or the pressure plate 42 can rotate relative to the pull rod 43, and the pressure plate can approach or move away from the guide rail. By rotating the knob 41, the pressure plate 42 can be pressed against or away from the guide rail, thereby achieving the side engagement between the pressure plate 42 and the locking part 31 to clamp the guide rail and fix the holographic diffraction sight with the quick-release structure to the corresponding device, or the guide rail can be released, so that the holographic diffraction sight with the quick-release structure can be quickly removed from the corresponding device.

[0036] Please see Figures 1 to 5Preferably, the knob 41 and the pressure plate 42 are located on opposite sides of the locking part 31 along the travel direction of the guide rail. A guide hole 32 is provided on one side of the locking part 31, and the pressure plate 42 is disposed in the guide hole 32, moving along the guide hole 32. This restricts the rotation of the pressure plate 42, allowing the pressure plate 42 and the pull rod 43 to rotate relative to each other when the knob 41 drives the pull rod 43 to rotate, thereby displacing the pressure plate 42 to clamp or release the guide rail.

[0037] Please see Figures 1 to 5 Preferably, a portion of the guide hole 32 extends through one side of the latching part 31 and communicates with the space between the two sides of the latching part 31, allowing the pressure plate 42 to move along the guide hole 32 into the space between the two sides of the latching part 31. This allows the pressure plate 42 to contact and clamp the guide rail through the guide hole 32.

[0038] Please see Figures 1 to 5 Preferably, the pull rod 43 has a thread on its circumferential surface away from the knob 41, and the pressure plate 42 has a threaded hole.

[0039] Please see Figures 1 to 6 A positioning pin 44 is installed on the end face of the latching part 31 that connects with the end face of the knob 41 facing the pressure plate 42. A plurality of first positioning grooves are arranged in a circular array on the end face of the knob 41 facing the pressure plate 42. The positioning pin 44 cooperates with the first positioning grooves to limit the movement. The end face of the latching part 31 that abuts against the knob 41 is provided with the positioning pin 44. A plurality of first positioning grooves are arranged in an array on the surface of the knob 41 facing the positioning pin 44. The positioning pin 44 and the first positioning grooves cooperate to limit the rotation of the pull rod 43, ensuring that each rotation of the knob accurately drives the pressure plate to the designated position and stops, preventing it from rotating on its own and ensuring that the scope can be fixed on the guide rail.

[0040] Please see Figures 1 to 5 A first spring 45 is provided between the end of the pressure plate 42 facing the knob 41 and the inner end face of the guide hole 32; the longitudinal section of the locking part 31 is C-shaped or T-shaped. The first spring 45 provided between the end of the pressure plate 42 facing the knob 41 and the inner end face of the guide hole 32 provides a force to keep the pressure plate 42 away from the guide rail, that is, to provide the knob 41 with a force that always abuts against the outer side of the locking part 31, so as to ensure that the knob 41 can drive the pull rod 43 to move every time it is rotated.

[0041] Please see Figures 1 to 5Preferably, the lower surface of the snap-fit ​​portion 31 of the connecting seat 3 is provided with a limiting strip 33, which matches the limiting groove on the guide rail. When the limiting strip 33 is aligned with the groove of the pickup truck guide rail, it indicates that the connecting seat 3 is aligned with the guide rail.

An adjustment port is provided at the end; the other ends of the first lead screw 23 and the second lead screw 24 are both located in the lead screw groove on the inner wall of the mirror body 1; a third spring 25 is provided between the exposed ends of the first lead screw 23 and the second lead screw 24 and the mirror body 1; a plurality of second positioning grooves are arranged in a circular array on the end faces of the first lead screw 23 and the second lead screw 24 facing the mirror body 1; a second ball bearing 26 is provided at the end of the third spring 25 facing the second positioning groove, and the second ball bearing 26 is pushed into the second positioning groove by the third spring 25. A second positioning groove is provided on the screw head end face of the first lead screw 23 and the second lead screw 24, and a third spring 25 is provided between them and the side of the connecting seat 3, so as to press the second ball bearing 26 into the second positioning groove, so as to play a limiting role and ensure that the first lead screw 23 and the second lead screw 24 will not rotate when there is no external force, thus ensuring the stability of holographic imaging. The third spring 25, in conjunction with the second ball 26, can also provide feedback for rotating the lead screw, producing a clicking sound feedback and providing a better feel.

[0043] Please see Figure 1 , Figures 5 to 11Preferably, a support column is provided between the connecting plate 29 and the base plate of the mirror body 1. A fourth spring 27 passes through the support column and abuts against the connecting plate 29 and the base plate of the mirror body 1.

Other specific structures of the micrometer adjustment optical path and the working principle of adjusting the micrometer can be found in the patent document with announcement number CN215676674U, which will not be described in detail here.

[0044] Please see Figure 1 , Figure 2 Preferably, the base plate of the mirror body 1 is equipped with an air-filling screw 5, which allows nitrogen to be filled into the mirror body 1 for drying. The connecting base can be integrated with the mirror body 1, or it can be fastened together with screws or the like.

[0045] The working principle of this utility model is as follows: When removed from the packaging, the knob 41 of the quick-release mechanism 4 of the connector 3 is in the locked position. Before connecting to the Picatinny rail on the device, rotating the knob 41 drives the pull rod 43 to rotate, which in turn drives the pressure plate 42 to move away from the knob 41 along the guide hole 32. Align the limiting strip 33 of the connector 3 with the limiting groove of the Picatinny rail, and then rotate the knob 41 in the opposite direction to move the pressure plate 42 toward the knob 41 to clamp the rail.
