Background

The hand throwing net is a current and more common and traditional fishing tool, and is gradually replaced by some high-tech fishing equipment with the transition of times, so that the hand throwing net is gradually changed from a fishing production tool to a leisure fishing tool. The hand-throwing net-fishing generally adopts a hand-grasping net-stretching method, and the net throwing is required to be accurate and fast, so that the catching amount is more likely to be improved. However, to do so, people who want to throw the net have a very skilled net throwing technology, and it is not practical for leisure fishers to spend a lot of time learning and mastering the net throwing technology. Therefore, the traditional hand throwing net is not suitable for new leisure fishing needs, the traditional hand throwing net not only requires a fisherman to have a higher net throwing technology, but also requires higher physical requirements for the fisherman due to the fact that the net of the fishing net is dropped and heavy, the fishing net can be thrown out by large force when the net is thrown, and therefore, the suitable net throwing device is very important for the leisure fishing person.
