On both sides near the rear position inside the third fixing block 27, pressing blocks 28 are also provided, and the inner side of the third fixing block 27 is welded to one side of the pressing block 28. The pressing block 28 is designed with a rubber material;

[0038] During operation, when the adapter arm main body 22 is in the upper position, the adapter arm main body 22 is inserted into the upper third fixing block 27. When rotating, it drives the adapter arm main body 22 to press the pressing block 28 to rotate and disengage from the inside of the third fixing block 27 until it is inserted into the lower third fixing block 27. And the pressing block 28 inside the third fixing block 27 will be squeezed and deformed. When it is inserted into the third fixing block 27 later, the pressing block 28 automatically rebounds to squeeze the adapter arm main body 22.

[0039] Working principle: When it is necessary to remove the adapter arm and the night vision device together, first rotate the rotating handle 14 to drive the first threaded rod 13 to rotate along the inside of the second fixing block 12. The limiting blocks 18 at both outer ends of the first threaded rod 13 can play a limiting role for the first threaded rod 13 to prevent the position of the first threaded rod 13 from shifting. When the first threaded rod 13 rotates, it drives the moving blocks 15 on both sides to move outward along the outside of the first threaded rod 13, and at the same time drives the first insertion block 16 to move outward along the inside of the connecting block 10 until the first insertion block 16 completely disengages from the inside of the connecting block 10. And during the movement of the moving block 15, it will move along the outside of the guide rod 17 at the same time. Then pull the first fixing block 11 outward to drive the second insertion block 20 to move outward along the inside of the slot 19 until the second insertion block 20 is completely disengaged, which is used to remove the adapter arm and the night vision device together.

[0040] When using the night vision device, first turn the adapter arm body 22 downward. The adapter arm body 22 will rotate along the outside of the fixed seat 21. Since the adapter arm body 22 is inserted into the upper third fixing block 27 when it is in the upper position, during rotation, it drives the adapter arm body 22 to squeeze the squeezing block 28 to rotate and disengage from the inside of the third fixing block 27 until it is inserted into the lower third fixing block 27. And the squeezing block 28 inside the third fixing block 27 will be squeezed and deformed. When it is inserted into the third fixing block 27 later, the squeezing block 28 automatically rebounds to squeeze the adapter arm body 22. Then start the motor 24 inside the groove 23 to drive the second threaded rod 25 to rotate, and the front end of the second threaded rod 25 will rotate along the inside of the adapter arm body 22. When the groove 23 rotates, it drives the night vision device body 2 to move back and forth along the outside of the groove 23 for adjustment, for using the night vision device.

[0041] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
