AI Technical Summary
The existing disc-lock scaffolding system suffers from inaccurate pin positioning and requires manual hammering for tightening during construction, leading to construction delays, unstable connections, and safety hazards.
The design employs a combination of a first support plate, adjustment structure, connector, and pin. By rotating the handle wheel, the pin is moved precisely, enabling quick locking and releasing of the horizontal or diagonal bar. Combined with the second support plate and guide rod, the stability and guidance of the connection are ensured.
It simplifies construction operations, improves connection efficiency, enhances connection stability, avoids pin loss, and ensures construction safety and progress.
