Background technique

It is known that the existing hand-held stabilizers are generally composed of a pan-tilt that can fix the shooting device and a frame that is connected to the pan-tilt at one end and is used to support the pan-tilt, wherein the frame is generally an upright rod The structure can be held by the photographer and used to lift the shooting part when shooting. There is a problem with such a rack with a slender rod-like structure: In actual use, when shooting a subject in a special position, such as shooting a low target, the stabilizer needs to be tilted downward, while the shooting target is high When shooting, it is necessary to tilt the stabilizer upwards. In these two shooting situations, for the straight-rod handheld gimbal, the tilt angle of the gimbal with the shooting device is relatively large, which is likely to cause discomfort to the wrist. During the process, the wrist will quickly feel muscle fatigue, and it is prone to shake, which will affect the shooting effect. Moreover, people who take pictures at a large tilt angle for a long time may also easily cause damage to the wrist joints and muscles.

Therefore, there is still a need in the industry to provide a stabilizer and its frame assembly that conform to ergonomics, have a changeable operating posture, and have an adjustable inclination angle during use.
