Description

Technical Field

[0001] This utility model relates to the field of free lock technology, specifically to a split-type wheel free lock. Background Technology

[0002] Pipe winding machines are used to wind pipes. When needed, the pipe is released, and when not needed, it is retracted, making it easy to store the pipe and reducing the space occupied during storage. However, existing pipe winding machines do not have a free lock. When the water pipe is pulled out, it is impossible to fix the wheel with the free lock, causing the water pipe to slide back and forth due to the rotation of the wheel, which affects the water pipe pulling effect and affects the safety of use.
