The rotation must be smooth and without lag, and the operator must have real-time feedback on the rotation feel to achieve good rotation damping in a smaller space. However, there is currently no more effective solution. Utility Model Content

[0003] The purpose of the utility model is to provide a simple structure for enhancing the damping of the rotation feel, so as to solve at least any one of the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: including a handle assembly, the handle assembly including a battery, a handle shell and a handle rotating shaft, a peep module is arranged at the bottom of the handle shell, the peep module includes a peep mirror and a metal rod, the metal rod passes through and is arranged at the bottom of the handle shell, a peep mirror is arranged on the top of the metal rod, a camera module is arranged at the front end of the metal rod, a display screen assembly, an image processing and display unit, a shell, a display screen back frame and a rotating shaft are arranged on the top of the handle assembly, the end face of the display screen back frame matching with the rotating shaft is designed with meshing teeth, the end face of the rotating shaft matching with the display screen back frame is designed with interference tongues, and the meshing teeth are adapted to the interference tongues.

[0005] Preferably, the handle shell is threadedly connected to the handle shaft.

[0006] Preferably, the top of the handle shaft passes through the middle position of the rear end of the shell, and the image processing and display unit is arranged on the top of the shell.

[0007] Preferably, a battery is provided in the handle shell.

[0008] Preferably, a main control board assembly is disposed in the housing.

[0009] Preferably, friction stripes are provided on the handle shell.

[0010] The beneficial effects of the utility model are as follows: rotation damping is generated by friction between the meshing teeth and the interference tongue during rotation. Since the plastic part can produce micro-deformation, the interference tongue on the rotating shaft is slightly deformed and rubs against the meshing teeth during rotation, generating a hand feel.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] The utility model provides Figure 1-6A simple structure for enhancing the damping of the rotation feel is shown, comprising a handle assembly 10, the handle assembly 10 comprising a battery 3, a handle shell 4 and a handle shaft 5, a peep module 11 is arranged at the bottom of the handle shell 4, the peep module 11 comprises a peep mirror 12 and a metal rod 1, the metal rod 1 penetrates and is arranged at the bottom of the handle shell 4, a peep mirror 12 is arranged at the top of the metal rod 1, a camera module 2 is arranged at the front end of the metal rod 1, a display screen assembly 6, an image processing and display unit 9, a shell 7, A display screen rear frame 16 and a rotating shaft 15, wherein the end faces of the display screen rear frame 16 and the rotating shaft 15 are designed with meshing teeth 14, and the end faces of the rotating shaft 15 and the display screen rear frame 16 are designed with interference tongues 13, wherein the interference tongues 13 are plastic parts, and the meshing teeth 14 are matched with the interference tongues 13, and rotational damping is generated by the friction between the meshing teeth 14 and the interference tongues 13 during rotation. Since the plastic parts can produce micro-deformation, the interference tongues 13 on the rotating shaft 15 are slightly deformed during rotation and rub against the meshing teeth 14 to produce a tactile feel.
