Mushroom Pin Conical Head Tilting: Jamming Kinetic Pick Guns

Engineering Overview: Technical analysis of conical mushroom driver pins, detailing angular tilting kinematics that jam vibrating electric pick gun needles.

Technical & Engineering Specifications

Defeats Electric Pick Guns (EPG), Manual Snap Guns, Rakes
Material Hardened H59 Leaded Brass / Stainless 304
Pin Profile Asymmetric Conical Mushroom Driver Pin
Kinematic Action Angular Tilting & Chamber Wall Wedging

Anti-Vibration Jamming Action

Electric pick guns rapidly vibrate keyway needles to bounce driver pins across the shear line. Conical Mushroom Pins neutralize this kinetic bounce.

Asymmetric Tilt Binding

  • Conical Head Profile: Features a tapered mushroom head ($\Phi 2.4\text{ mm}$ flaring to $\Phi 2.7\text{ mm}$).
  • Instant Tilting: Vibrating impacts cause the tapered head to tilt diagonally inside the chamber bore, wedging firmly against the chamber wall and jamming the plug.

Frequently Asked Engineering & Selection Questions

Q1: How do mushroom pins jam electric pick guns?

Their tapered conical heads tilt sideways under vibration, wedging tightly against the chamber walls and stopping the pins from jumping across the shear line.
