Feature: The 19mm Tube Clip Fine-Tuning is made of aluminum alloy, which increase strength and sturdiness. The Motor Buckle Fine-Tuning Bracket Supports Multi-angle Adjustment. Easily adjust motor engagement. This 19mm Tube Clip Fine-Tuning features an M4 screw knob for adjusting the angle of the motor mounted on the main body. One side of the 19mm tube is secured by a toothed disc and serves as the motor tube fixed to the body. After locking the motor orientation with the M4 screw knob, a secondary screw allows for precise fine-tuning of the motor, enabling accurate alignment between the motor and the lens gear. Tightening the screw presses the lens downward, while loosening it adjusts the lens gear upward for smooth and reliable meshing.
