我和几位钓友研制出一种灵敏的海竿挂铃装置。经试用,它既避免了竿梢挂铃时铃铛时被抛出去的弊端,又克服了铃挂线、线绕铃的毛病,效果十分理想。 做法:先做工具。取一直径约12毫米,长330毫米左右的圆木棍,用快刀将其一端削成长45毫米的圆锥体(端面不要削尖,其直径应为5毫米),再用钢锯条在端面上锯一条深约3毫米左右的槽。 I and several fishing friends developed a sensitive sea rod hanging bell device. After the trial, it not only avoids the drawbacks of being thrown out when the bell hangs, but also overcomes the problems of the bell hanging and the line winding the bell, and the effect is very satisfactory. Approach: first do tools. Take a round stick with a diameter of about 12 mm and a length of about 330 mm. Use a sharp knife to cut one end into a 45 mm long cone (the end face should not be sharpened and its diameter should be 5 mm), and then saw the end face with a hacksaw blade A groove about 3 mm deep.
