[0002] Handheld night vision devices can be paired with blacklight full-color cameras, which are low-light and high-resolution cameras that can provide clear, detailed images and videos in dark environments. Blacklight full-color cameras combine the technology of black-and-white cameras and color cameras. By using special optical filters and image processing algorithms, they can effectively utilize infrared light and maintain good color reproduction capabilities in images.

[0003] After searching the existing public documents, the utility model patent with patent publication number CN217238519U discloses a handheld low-light night vision device. The night vision device is not convenient to hold when in use. The hand is easily tired and falls off after a period of use. The night vision device with a handle is not convenient to carry. The existing night vision device usually has a display screen, but the display screen is easily crushed during the carrying process of the night vision device. The handle structure connected by rotation cooperates with the lifting belt, and the handle is stored in the storage slot for easy carrying of the device. The handle is rotated outward for easy holding, which improves the stability of the device. However, the handheld night vision device still has the following defects:

[0004] When the above-mentioned handheld night vision goggles are used at night, the hand needs to squeeze the hand to hold the handheld night vision goggles.
