<p>The present invention relates to a fishing sinker. A buoyancy adjustment space is arranged inside an upper part of a body of the fishing sinker. An actual volume of the buoyancy adjustment space is adjusted by a lower part, which is joined with the upper part to be able to vertically move. The weight adjustment rind is detachably installed by an upper swivel and a lower swivel, which are arranged on the top of the upper part of the body and on the bottom of the lower part of the body, respectively; thus, the total weight of the fishing sinker can be firstly adjusted. The balance between buoyancy of a fishing float and the weight of the fishing sinker can be subtly adjusted by secondly adjusting buoyancy.</p> |
