The present invention relates to a pusher of fishing sinker. The pusher includes: a base, an upper cover, a pressing plate, a fishing sinker cassette module, a conveying module, and bolt members. The base has an installation part, a sliding track, a receiving slide groove, a positioning column, a clamping platform, and a corresponding base to provide installation for the fishing sinker cassette module and the conveying module. The upper cover has a recess part to provide installation for the pressing plate. The pressing plate has a plurality of through holes, and one end of the pressing plate extends to form a pressing member. The fishing sinker cassette module has a fishing sinker storing cassette member and a fishing sinker pushing member. The conveying module has a conveying shaft member, a positioning member and a pushing shaft member. The bolt members fasten the entire components. Accordingly, the present invention not only can use the cassette module to store the fishing sinkers, but also can fast convey the fishing sinker along the fishing line and accurately clamp the fishing sinker and the fishing line together, so as to promote the clamping efficiency of the fishing sinker.本發明一種咬鉛推送器，該推送器包括：一底座、一上蓋、一壓板、一咬鉛匣具模組、一運送模組及栓件，該底座具有設置部、滑移軌道、容置滑槽、定位柱、夾固台及對應座，供與咬鉛匣具模組、運送模組設置，該上蓋具有凹設部供與壓板設置，該壓板具有複數穿孔，該壓板係一端延伸壓制件，該咬鉛匣具模組具有咬鉛儲置匣件及咬鉛推送件，該運送模組具有運送桿件、定位件及推桿件，該栓件具固持整體元件，藉此，本發明不僅能以匣具模組作為複數咬鉛儲存，且能快速將咬鉛運送及準確夾固至魚線間使用，以提升咬鉛夾固效率。
