The knob-grip locking quick-release pin is a simple and efficient fastening, allowing easy control of the pin's insertion, locking, and release with a quick turn and pull of the knob. No complicated tools or processes are needed, making it ideal for fast operations.
The knob is typically round or hexagonal, you can easily rotate it to lock or unlock the pin just with one hand, even in tight spaces. Made from stainless steel, this knob-grip locking quick-release pin offers excellent corrosion resistance, ensuring a reliable performance even in harsh environments.
An internal spring ensures that after releasing the knob, the pin's front end automatically returns to its extended position, making it ready for the next time use. By rotating the knob at a set angle (such as 90 degrees), the pin can be locked in the retracted position. The durable construction gives it a long lifespan, reducing the need for frequent replacements.
The knob-grip locking quick-release pin can be installed or removed quickly, boosting efficiency by more than 80% compared to traditional bolts. It is commonly used in mechanical equipment for quick positioning. It is also widely used in industries such as metal sheet installation and tight-space applications, meeting various industrial needs.
