The adjustment handle of tripod head for live broadcast is loose. Why?

When the adjustment handle of the pan/tilt is loose, it can be solved by tightening the screws. Find the loose handle and the corresponding screw. Use a suitable tool, such as a wrench or screwdriver, and turn the screw counterclockwise to tighten it. Make sure the screws are firmly fixed, but be careful not to tighten them too tightly to avoid damaging the screws or other parts. This can restore the stability of the tripod head and the function of adjusting the handle, and ensure the smooth progress of live broadcast or shooting activities.
