[0043] Drive mechanism 9 is installed on extension column 4, and drive mechanism 9 is connected with support shaft 7, and is used to adjust the working angle of camera device on fixed piece 8;

[0044] The working principle of the device is as follows:

[0045] First, the supporting mechanism 2 is expanded by the adjusting mechanism 3 to ensure the stability of the traction frame during work, and then the height of the extension column 4 is adjusted by the control mechanism 6 to make the camera device reach the appropriate working height, and the driving mechanism 9 is started to drive the supporting shaft 7 to rotate, thereby adjusting the working angle of the camera device on the fixing part 8 to meet the needs of live shooting;

[0046] The mounting part 1 is independently fixed and adopts a regular polyhedral structure, which not only lays a stable foundation for the entire traction frame, but also is more reasonable in space layout due to its unique shape. When the supporting mechanism 2 installed on each end face is expanded under the action of the adjusting mechanism 3, it provides stable support from multiple directions, greatly enhancing the stability of the traction frame during work, adapting to various complex live site environments. The adjusting mechanism 3 arranged on the mounting part 1 is easy to operate and can easily expand and store the supporting mechanism 2, facilitating the carrying and storage of the traction frame and improving the convenience of use. The extension column 4 in the shaft cavity of the mounting part 1 can slide along the length direction, cooperate with the control mechanism 6, and accurately adjust the connection position with the mounting part 1, thereby flexibly changing the height of the traction frame to meet the diversified needs of different live scenes for the working height of the camera device.

The omnidirectional meeting of the live industry's flexible, stable, and efficient use requirements of the equipment.

[0047] As a preferred solution, as shown in Figures 1 to 6 The adjusting mechanism 3 comprises:

[0048] The moving part 31 is arranged in the shaft cavity of the mounting part 1, and a plurality of assembly parts 32 are arranged at equal angles on the extension part 5, and the assembly part 32 corresponds to the supporting mechanism 2 one by one. The assembly part 32 is connected with the supporting mechanism 2 through the through slot of the mounting part 1;

[0049] The threaded rod 33 is rotationally installed on the mounting part 1, and the threaded rod 33 is installed in cooperation with the threaded hole of the moving part 31;

[0050] The driving wheel 34 is coaxially installed on the threaded rod 33, and the anti-skid groove is arranged on the outer wall of the driving wheel 34;

[0051] The moving piece 31 in the shaft cavity of the mounting piece 1 cooperates with the assembly piece 32 of the support mechanism 2 arranged at the same angle and corresponding connection on the extension piece 5 to build an efficient support mechanism to open and store the transmission system. The threaded rod 33 rotatingly installed on the mounting piece 1 is accurately matched with the threaded hole of the moving piece 31. When the rotating drive wheel 34 rotates, the good holding force brought by the outer wall anti-skid groove can easily drive the threaded rod 33 to rotate, thereby driving the moving piece 31 to move stably along the axial direction of the threaded rod 33 in the shaft cavity of the mounting piece 1. The movement of the moving piece 31 synchronously drives the plurality of support mechanisms 2 through the assembly piece 32 to realize the rapid opening or storage of the support mechanism 2. This design greatly facilitates the deployment and storage of the traction frame in different scenes and improves the use efficiency of the equipment.

[0052] As a preferred solution, as shown in Figures 1 to 4 The support mechanism 2 comprises:

[0053] Two support frames 21 are symmetrically installed on the same side outer wall of the mounting piece 1, and a transmission shaft 22 is arranged on the support frame 21.

[0054] An auxiliary arm 23 is rotatingly installed on the transmission shaft 22, and a mounting shaft 24 is arranged on the two auxiliary arms 23, and the axis of the mounting shaft 24 is arranged in parallel with the axis of the transmission shaft 22.

[0055] A support leg 25 is rotatingly installed on the mounting shaft 24, and the support leg 25 is rotatingly installed with the assembly piece 32. The rotating axis of the support leg 25 is arranged in parallel with the rotating axis of the auxiliary arm 23.

[0056] A universal wheel 26 is arranged on the support leg 25, and a locking structure is arranged on the universal wheel 26.

[0057] The two support frames 21 symmetrically installed on the same side outer wall of the mounting piece 1 provide a stable installation basis for the entire support structure. The transmission shaft 22 installed on the support frame 21 provides reliable support and rotating shaft for the rotation of the auxiliary arm 23, so that the auxiliary arm 23 can rotate flexibly. The mounting shaft 24 arranged on the two auxiliary arms 23 is parallel to the axis of the transmission shaft 22, which creates conditions for the rotating installation of the support leg 25 and ensures the coordinated action of the support leg 25 during the unfolding and storage process. The support leg 25 is rotatingly installed with the assembly piece 32, and its rotating axis is parallel to the rotating axis of the auxiliary arm 23. When the adjusting mechanism 3 drives the assembly piece 32 to act, the support leg 25 can accurately and smoothly follow the movement to realize the opening and storage. The universal wheel 26 on the support leg 25 makes the traction frame very convenient to move and can flexibly turn to adapt to the space layout of different live broadcast sites. The locking structure on the universal wheel 26 can quickly fix the traction frame after it reaches the working position to prevent accidental movement and ensure the stability of the equipment during live broadcast.

[0062] The auxiliary frame 91, mounted on the extension column 4, provides a stable mounting platform for the worm gear 92, ensuring its stable rotation during operation. The worm gear 92, mounted on the auxiliary frame 91, precisely meshes with the worm wheel 93, which is mounted on the support shaft 7, forming a stable and reliable transmission connection. When the operator rotates the adjusting wheel 94, since the adjusting wheel 94 is coaxially mounted with the worm gear 92, it easily drives the worm gear 92 to rotate. The rotation of the worm gear 92, through meshing with the worm wheel 93, efficiently transmits the rotational motion to the support shaft 7, thereby driving the camera device on the fixed component 8 to operate. The worm gear drive has a large transmission ratio, which makes the adjustment process more precise and accurate. Operators can make small changes to the camera angle by fine-tuning the adjustment wheel 94, meeting the needs of precise shooting angle adjustment during live broadcasts. At the same time, the self-locking characteristic of the worm gear drive can effectively prevent the camera from changing its angle due to external vibrations or other interference factors after it is adjusted to the appropriate angle, ensuring that the camera always maintains the set working angle, providing stable and reliable images for live broadcast shooting, and comprehensively improving the functionality and practicality of the live broadcast equipment traction frame.
