A low-cost, easy-to-use and light-weight fishing line and a telescopic bus line are connected between the fishing line and the telescopic bus line of the telescopic bus line. The upper end of the line body of the connection line group is a circle for connection. For fishing gear, the lower end of the line body of the connecting line group is another circle body or a wear-resistant element fixed at the lower end of the line body and having a through hole for the connection of the telescopic busbar； to achieve the expansion and contraction of the fishing line and the fishing line using the connecting line group When the bus is between, it makes the telescopic bus easier and lighter when operating the telescopic length.一種成本低、使用簡易且操作輕巧的釣具與伸縮母線的連結線組，連結線組係連結於釣具及釣線的伸縮母線之間，該連結線組的線體上端為一圈體用於連結釣具，連結線組的線體下端則為另一圈體或固定在線體下端並具有貫穿孔的耐磨元件以供伸縮母線的串接；以達到利用連結線組連結於釣具及釣線的伸縮母線之間時，使伸縮母線在操作伸縮長短時更為簡易、輕巧。
