# Telescopic rod with a step

## Abstract

A tripod comprising a main body with a rotating cavity at the upper end, a ball rotatably arranged in the rotating cavity, and a ball swing locking mechanism for locking or releasing the ball; the ball swing locking mechanism comprises a locking assembly that is slidably matched with the main body, a reset elastic member located between the locking assembly and the main body, and a limiting assembly connected to the main body and provided with a movable pin that cooperates with the locking assembly; in response to the locking assembly slides under an external force, the movable pin may be moved and positioned to a locked position or an unlocked position; in the locked position, the locking assembly presses against the ball to limit the axis swing of the ball; in the unlocked position, the locking assembly releases the ball to allow the ball to swing.
