The specific position of the first elastic member 8 is not limited, as long as the first driving gear 51 is provided in close contact with the second gear 33. For example, the first elastic member 8 is disposed between the horizontal rotation base 4 and the up-down rotation motor bracket 52 so that the first driving gear 51 is in close contact with the second gear 33, and the first elastic member 8 may be a spring or the like.
The rotating support 2 and the horizontal rotating base 4 are fixed through bolts or screws. The second driving gear 61 on the horizontal rotating motor 6 enables the horizontal rotating motor 6, the horizontal rotating base 4, the rotating support 2 and the turntable 2 to rotate together, so that the rotating piece 12 connected with the rotating support 2 and the camera are driven to rotate, and horizontal left-right angle adjustment of the camera is achieved.
The up-down rotation motor 5 drives the turntable 2 to rotate through the first driving gear 51 and the second gear 33 on the turntable 2, and the first gear 32 on the turntable 2 drives the rotating member 12 to rotate through the rotating gear 123 on the swing arm 121, so that the rotating member 12 is driven to rotate or swing up and down, and the up-down angle adjustment of the camera is realized.

The horizontal rotation motor 6 and the vertical rotation motor 5 can operate simultaneously as required, and interference between the vertical rotation transmission assembly and the horizontal rotation driving mechanism and the like is not generated. Due to the first elastic component 8 which enables the first driving gear 51 to be in close contact with the second gear 33, the requirement on the matching precision between gears can be reduced, the machining difficulty of the components can be reduced, noise can be avoided when the components are in too low precision, namely the matching clearance is too large, the precision is too high, the matching is tight, namely the phenomenon of shaking, discontinuity and the like occurs when the matching clearance is too small, the running stability is improved, the structure is compact, and the size is small.
In order to ensure the cooperation between the second driving gear 61 and the inner gear 71, when the mechanical cooperation clearance is too large, larger noise is generated during horizontal rotation, when the cooperation clearance is too small, the processing difficulty is increased due to high processing precision requirement, and the phenomena of blocking and the like are easy to occur, so that the phenomenon of video image blocking discontinuity of camera acquisition occurs due to unstable operation of the cradle head during working. The automatic tracking head is further provided with a second elastic member 15 for bringing the second driving gear 61 into close contact with the internal gear 71 on the cover 7. The specific position of the second elastic member 15 is not limited as long as the second driving gear 61 is brought into close contact with the internal gear 71. In this embodiment, a second elastic member 15 for bringing the second driving gear 61 into close contact with the internal gear 71 on the cover 7 is provided between the horizontal rotation base 4 and the second motor bracket 62, and the second elastic member 15 may be a spring or the like.
