When a structure needs to be quickly installed and removed, you can consider using quick-release pins.
Quick-release pins work by pressing the tail end, causing the pin rod inside the body to extend and retract, causing the steel ball to fall into the groove of the pin rod. Once the tail end is no longer under pressure, the internal pin rod springs back under the force of the spring, causing the steel ball to protrude, thereby achieving the quick-release function on the connecting parts.
