Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of live broadcast shooting frame, especially to a kind of rotation mechanism for live broadcast shooting frame adjustment shooting angle. BACKGROUND

[0002] In the current live broadcast and mobile shooting field, as the key tool for supporting mobile phone equipment and assisting to obtain stable picture, the performance of mobile phone support is decisive for shooting effect. However, the existing mobile phone support has many restrictive factors in realizing full-angle shooting function, and it is difficult to meet the increasingly diverse shooting needs. The traditional mobile phone support mostly adopts simple joint connection mode, such as common ball joint or shaft joint. Although the ball joint can realize multi-angle rotation to a certain extent, its rotation range is limited by the size and structure of the joint itself in actual operation. For example, when the mobile phone needs to be adjusted to an extreme angle close to vertical downward or vertical upward, the ball joint will be interfered by other parts of the support, and cannot reach the ideal angle, resulting in blind area of shooting angle. The shaft joint can usually only rotate within a limited angle in one plane, such as horizontal or vertical direction, and it is difficult to realize complex full-angle adjustment. When shooting some scenes that need to be shot from bottom to top or from top to bottom, the limitation of shaft joint will be highlighted, and it cannot meet the demand of unique angle of the shooter. The adjustment mechanism of existing mobile phone support is often not flexible and accurate. Some supports fix and adjust the angle through bolt and nut structure, and the live broadcaster needs to manually loosen or tighten the nut with tools to change the angle of the support. This operation method not only consumes time and effort, but also is difficult to accurately control the change of angle during adjustment. In the process of live broadcast, if the shooting angle needs to be quickly switched to capture the wonderful moment, this cumbersome and inaccurate adjustment method is easy to cause the picture to shake or lag, which seriously affects the smoothness and ornamental value of live broadcast. In addition, although some supports adopt buckle type adjustment mode, the position of buckle is fixed, and only a limited number of preset angles can be provided, which cannot meet the demand of accurate adjustment of any angle for the shooter, and limits the diversity of shooting angle.
