A balance for catching shrimps,Including: a balance bar,There is a first connecting part and two cantilevers,The cantilever is arranged at both ends of the first connecting part；An elastic part,It is arranged on the balance rod,And the elastic member is combined with the cantilever；And two sleeves,It is sheathed on the cantilever of the balance rod,The elastic arms of the elastic member extend into the sleeve respectively；The cantilever is deformed by an external force,The elastic part stores an elastic potential energy,When the external force is removed,The elastic part releases the elastic potential energy,The elastic member drives the cantilever to reset by the sleeve.With the sleeve, the elastic arm of the elastic element can drive the cantilever of the balance rod to reset without worrying about the permanent deformation of the cantilever.一種釣蝦天平，包含：一天平桿件，有一第一連接部及二懸臂，所述懸臂設置在該第一連接部的兩端；一彈性件，設置在該天平桿件，且該彈性件結合於所述懸臂；以及二套筒，套設於該天平桿件的所述懸臂上，該彈性件的所述彈性臂分別伸入所述套筒中；所述懸臂受一外力作用而變形後，該彈性件儲存一彈力位能，當該外力移除時，該彈性件釋放該彈力位能，該彈性件藉由所述套筒帶動所述懸臂復位。藉由所述套筒，該彈性件的所述彈性臂可以帶動該天平桿件的所述懸臂復位，無需擔心所述懸臂永久變形。
