Load bracket and gimbal

Abstract

A load bracket includes a guide rod, a locking assembly, and a mounting plate. The locking assembly is arranged at the guide rod and configured to slide with respect to the guide rod along a first direction. The mounting plate is slidably connected with a portion of the locking assembly. The portion of the locking assembly is configured to drive the mounting plate to move with the locking assembly along the guide rod in the first direction. The locking assembly is configured to move, along a second direction, with respect to the mounting plate to enable a relative movement, along the second direction, between the mounting plate and the guide rod. The second direction is different from the first direction.
