Abstract

The invention relates to the mechanical field, in particular to a rocker arm which comprises a base, a first support and a second support, wherein one end of the first support is connected with the base in a rotary mode through a rotary cloud platform, the other end of the first support is connected with one end of the second support in a rotary mode through a four-axis switching connector. A three-axis electrical cloud platform is connected with the other end of the second support, wherein the first support comprises at least two armed levers which extend in the same direction. The second support comprises at least two armed levers which extend in the same direction. Two shafts of the four-axis switching connector are respectively connected with two armed levers of the first support in a rotary mode; the other two shafts of the four-axis switching connector are respectively connected with two armed levers of the second support in a rotary mode. The rocker arm is capable of breaking away from artificial control at the time of shooting, and playing vital roles in presentation and control at the time of teaching platform showing and microscopic view shooting and the shooting effects are effectively guaranteed.

Description

technical field

[0001] The invention relates to the field of machinery, in particular to a rocker arm. Background technique

[0002] When shooting large scenes (such as TV series, movies, commercials and other large-scale film and television works), the jib is often used to operate the camera. The rocker arm is a large-scale equipment, which can mainly shoot the scene in all directions when shooting, without missing any corner. The rocker arm can not only adjust the level and facilitate the photographer to push, pull, and pan, but also can lift and lower the position of the camera. Furthermore, because the rocker arm does not need to directly hold the camera equipment, it can better fix the camera position and avoid shooting. Random jitter.

[0003] When shooting small scenes or microscopic scenes (such as when shooting flowers, small crafts or laboratory experiments), use a handheld camera for recording. Preferably, a Steadicam is further used, which is a lightweight cin...
