Lock-out Pull Pins with Clamping Knob

Locking pull pins with Clamping Knob|One-Handed Operation × Pause & Lock × Precision Adjustment

Lock-out pull pins with clamping knob allow the pin to remain retracted for hands-free adjustment, then re-engage for accurate positioning with added clamping stability in precision equipment.


UJEN supplies lock-out pull pins with clamping knob for modular equipment and precision assemblies, supporting hands-free adjustment, reliable positioning, and OEM/ODM customization through Taiwan-based manufacturing.

Core Function: Lock-Out Positioning with Hands-Free Adjustment

The lock-out pull pin with clamping knob features a built-in hold mechanism that keeps the pin in the retracted position after pulling and rotating the knob. This allows operators to use both hands for precise alignment, part replacement, or mold changes without repeatedly pulling the pin.

Once adjustment is complete, the pin can be re-engaged by rotating the knob back, restoring accurate and repeatable positioning.

Improved Lock-Out Operation Design

In the updated design, the pin can be reinserted directly by rotating the knob, eliminating the need to pull and rotate again. This improvement simplifies operation, reduces adjustment steps, and minimizes user error during high-frequency use.

Compared to earlier designs that required repeated pull-and-rotate actions, the new mechanism provides smoother and more intuitive operation.

Integrated Clamping for Added Stability

In addition to the lock-out function, the clamping knob allows manual tightening after positioning. This added holding force helps secure components against vibration and dynamic loads, improving overall system stability without additional fasteners.

Key Features

  • Lock-out mechanism holds the pin in the retracted position
  • Direct rotation to re-engage the pin without pulling again
  • One-hand operation for faster and safer adjustment
  • Manual clamping function for enhanced stability
  • Designed for frequent use and foolproof operation
  • ROHS compliant for global environmental requirements

Typical Applications

  • Equipment requiring frequent repositioning or mold changes
  • Automated modules and guide tracks with precision alignment needs
  • Medical, laboratory, and inspection equipment
  • Modular assembly lines with high-frequency adjustments
  • Safety-critical environments demanding reliable positioning

OEM / ODM Customization Support

UJEN provides OEM and ODM support for lock-out pull pins with clamping knob, including customization of pin diameter, stroke length, lock-out angle, clamping force, and knob design. Our engineering team works closely with customers to ensure safe, reliable performance in precision and safety-critical applications.
