Precision Adjustment Knob - Technical Diagram & Engineering Component #161462 (License: Personal Use)

This black-and-white line drawing depicts a precision adjustment mechanism, likely used in instrumentation or machinery. It consists of a threaded screw base for secure mounting, a central shaft with three spherical knobs (two for grip, one as a pivot), and a tapered lever handle for torque application. The clean drafting style suggests it’s from a patent, manual, or engineering catalog.

Used in technical documentation, engineering manuals, patent illustrations, or product specification sheets to convey mechanical function and assembly. Matches user intent for understanding component design, sourcing parts, or reverse-engineering mechanisms.
