However, the robotic arm fixing devices used in the prior art to connect the robotic arm and the shooting device have the following problems:

[0003] Unstable fixation: When the robotic arm moves at high speed and at multiple angles, it is easy to cause the shaking or displacement of the shooting device, affecting the shooting effect.
