笔者有一辆建150-AN型太子车,在骑行不足1000公里时,里程表软轴内的传动钢绳就从前轮处的四方头上断掉。本人找来一只家中常用的单联开关,取出开关按钮里的小弹簧,将四方头和软轴钢绳分别从弹簧两端插入,用钳子夹紧,然后在弹簧上缠绕一些细铜线,或用电焊将其焊接 I have built a 150-AN-type Prince car, riding less than 1000 km, the odometer inside the transmission cable from the front wheel at the square head off. I find a single family commonly used single switch, remove the switch button in the small spring, the square head and soft shaft steel cord from the spring ends are inserted, with the pliers clamp, and then wound on the spring some fine copper wire, Or weld it with electric welding
