[0024] Usage process:

[0025] When in use, when the public security investigation needs to record a case, it can be recorded through the head-mounted video device, freeing the hands. Specifically, the headband 1 is worn on the head circumference, and the head circumference is adjusted by setting the tension adjustment mechanism, so that the headband 1 is tightly covered on the staff's head to avoid the head-mounted video recorder from being misplaced or falling off during use; after wearing, the staff checks the height of the main video recorder 6 through the third-party video, and then adjusts the shooting height. When adjusting upward, the outermost adjustment rod 8 is manually rotated so that the adjustment rod 8 is threaded and raised to drive the fixing sleeve 9 to rise. Due to the limitation of the center rod 4, the front end adjustment shaft 5 is tilted upward at a certain angle. The fixing sleeve 9 changes the outer wall of the adjusting shaft 5, and the front end of the adjusting shaft 5 tilts to drive the main video recorder 6 to tilt upward, thereby completing the video recording height adjustment of the main video recorder 6. When it is necessary to adjust the adjusting shaft 5 downward, the adjusting rod 8 close to the face is rotated, and the adjusting rod 8 drives the fixing sleeve 9 to move upward, and drives the adjusting shaft 5 on the other side of the center rod 4 to move upward. At this time, the main video recorder 6 moves downward due to the raised tail, thereby realizing the height reduction of the main video recorder 6. Through the setting of two fill lights 17, the clarity of the shooting can be improved when the lighting is sufficient, and the two auxiliary video recorders 18 are used to record the surroundings, which is convenient for leaving useful clues for public security investigation and case handling, and realizing the integrity of the record.

[0026] In the above process, by arranging the support plate, the connecting seat, the central rod, the adjustment shaft, the groove, the adjustment rod, the fixing sleeve and the fill light, it is convenient to adjust the height of the main video recorder according to the recording needs, and different directions can be shot, which is convenient for people to use, and the fill light can make it possible to record videos when solving crimes at night, effectively solving the problem that it is inconvenient for operators to manually fill light the video recorder when recording; by arranging the tension adjustment mechanism, it is convenient to adjust the head circumference size to avoid the head-mounted video recorder from being dislocated or falling off during use, and it is convenient to adjust the tightness of the headband according to the head size of different users, which effectively increases the scope of application of the utility model; the application is simple in structure, strong in practicality, and simple in operation, and is worthy of promotion.

[0027] The above are only preferred implementations of the utility model. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the utility model. These should also be regarded as the protection scope of the utility model. These will not affect the effect of the implementation of the utility model and the practicality of the patent.
