Function

UJEN Mini Spring Pull Pins with Rest Position are designed specifically for rapid fastening, frequent adjustment, and convenient repositioning. Simply pull and rotate the top knob 106 degrees to maintain the pin in a fully disengaged (rest) position, allowing users the freedom to adjust components easily with both hands.

After repositioning, simply rotate the knob directly to re-engage the pin into the hole (new improved feature), eliminating the need for an additional pulling action. This innovative improvement significantly enhances operational efficiency.

Additionally, this mini pull pin enables quick hand-tightening by rotating the top knob manually, securely fastening components and effectively preventing vibration or looseness without tools. Widely used in fitness equipment, medical devices, mechanical assemblies, furniture hardware, and more, it provides a reliable solution for precise and rapid component adjustments.
