[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0031] In order to facilitate the function of assisting in recording the user's focus position, the flexibility and convenience of subsequent repeated use are greatly improved, thereby improving the use effect, such as Figure 1-4 As shown, a focusing mechanism of an AR device described in the utility model comprises AR glasses 1, a positioning component 2 and a positioning component 2, the positioning component 2 is arranged on the outside of the AR glasses 1, and a control component 3 is arranged on the bottom of the AR glasses 1;

[0032] The AR glasses 1 include a frame 101, and the positioning assembly 2 includes a positioning seat 201. The inner side of the positioning seat 201 is connected with a protrusion 202 by gluing. The bottom of the positioning seat 201 is threadedly connected with a positioning screw 203 through a reserved threaded hole, and one end of the positioning screw 203 passes through the frame 101. A sliding groove 104 is opened at the bottom of the frame 101, and a sliding block 105 is slidably connected in the sliding groove 104.

[0033] When in use, the bump 202, the positioning seat 201, and the positioning screw 203 can be used to quickly assist in positioning the focusing position after the initial focusing operation is completed, so as to facilitate quick positioning during subsequent repeated focusing, thereby improving the convenience and flexibility of repeated focusing operations.

[0034] In order to improve the convenience of focusing operation, for example, Figure 3 , Figure 4 As shown, the utility model also includes a guide rod 106 connected to the slide groove 104 by bolts, and the guide rod 106 passes through the sliding block 105, the periphery of the guide rod 106 is located on one side of the sliding block 105 and is connected to an annular air cushion 107 by gluing, and the periphery of the guide rod 106 is located on the other side of the sliding block 105 and is sleeved with a compression spring 108.

[0035] When in use, the deformation of the annular air cushion 107 and the elastic push of the compression spring 108 can assist in controlling the sliding of the sliding block 105, thereby achieving a fast focusing operation and improving the convenience of operation.

[0036] For example, Figure 4 As shown, the present invention also includes that a groove 109 corresponding to the protrusion 202 is formed on the surface of the lens frame 101 .

[0037] When in use, the groove 109 facilitates the positioning seat 201 to be slidably connected with the protrusion 202 .

[0038] For example, Figure 5 As shown, the utility model also includes that the control component 3 includes a fixed seat 301, the surface of the fixed seat 301 is connected to an elastomer 302 by gluing, the air inlet end of the fixed seat 301 is connected to a one-way valve 303 through a slot, and the air outlet end of the fixed seat 301 is provided with a hose 304, and the hose 304 is connected to the annular air cushion 107.

[0039] When in use, by pressing the elastic body 302 to produce elastic deformation, external air can be drawn into the annular air cushion 107 through the one-way valve 303 and the hose 304, and it is manually and quickly inflated. An air nozzle is provided on the outer surface of the frame 101, and the air inlet end of the air nozzle is connected to the hose 304.

[0040] For example, Figure 3 As shown, the utility model also includes that a front lens 4 is fixedly installed in the frame 101 through a card slot, a corresponding rear lens 5 is arranged on one side of the front lens 4, and a sliding block 105 is connected by bolts, and the frame 101 includes a display screen 6 and a miniature camera 7.

[0047] Moreover, according to the position of the tightening screw 8, the positioning seat 201 can be pushed to slide to the bottom of the tightening screw 8, and the positioning screw 203 can be screwed to assist in positioning it, so that when it is reused later, according to the change of the position of the tightening screw 8, the focusing operation can be quickly completed from the outside of the lens frame 101.
