AI Technical Summary
Existing crab harvesting devices are inconvenient to carry due to their long pole design, making it difficult to meet the requirements for portability.
A portable rapid sample collection device for mitten crabs was designed. The support rod is folded and stored by means of a support block, bearing, rotating rod and rotating sleeve. The structure of telescopic column, spring, sliding plate and plug rod is combined to improve the storage stability of the support rod. The support rod is fixed by locking bolts and nuts to ensure the stability of use.
This achievement ensures the portability and stability of the fishing tools, making them convenient for staff to carry and use, and improving the practicality of the collection device.
