Description

A new type of spinning fishing reel Technical Field

[0001] The present application relates to a novel spinning fishing reel, and in particular to a modularly designed spinning fishing reel in which the spool has both movement and rotational freedom. Background Art

[0002] Existing spinning reels: while the spool moves back and forth, the turntable rotates, driving the fishing line to be evenly wound around the spool. Because the diameter of the fishing reel turntable is at least 1.6 times larger than the diameter of the spool, and the turntable needs to have a certain size to ensure strength, the fishing reel naturally has a large moment of inertia; the gear box and casters of the fishing reel are an integrated structure, and the turntable is mounted outside the gear box. Changes in the size of the driving components in the gear box directly affect the size of the rest of the fishing reel, which is not conducive to the modular design of the fishing reel; during use, the gap between the turntable and the fishing reel body can easily cause liquid to flow in, eroding the driving components inside the fishing reel and causing corrosion of the fishing reel. Technical Solutions
