Usage Example/Method

Lift the handle to disengage the teeth from the locking element.

Turn the lifted handle to the desired position.

When the hand is released, the lever is returned and clamped due to the force of the internal spring. (When the number of teeth is 20, the teeth engage with the locking element every 18° (360°/20 = 18°))
