Stepless adjustment for angular position

The friction at contact place between orange cone and cone hole of the housing locks the blue hand under red spring force. Push blue hand to unlock, turn it to new position and release it to lock. A torque applied to the hand can not turn it if the hand is not at pushed position. The tapered angle should be small, around 1 to 3 deg.
