A kind of fishing line protector of what is closed in this creation system,The protector is up-narrow and down-wide cone cell kenel,The through-hole of perforation from top to bottom is formed inside what protector,And what bottom end forms the wears groove of lateral communication,Wears groove and through-hole are formed through fishing line accommodating space,And positioning region is formed at what wears groove,It is a solid retaining ring that fishing line can penetrate Hou from the through hole on protector top,Retaining ring bottom end is Gu Yu Hook and false bait again,And make at retaining ring limit what positioning region without dropping out protector bottom end,Thereby make protector position Yu Yu Hook,Light wave water shadow maximum when false bait is shaken,When Hook Shang Yu is quasi- bites fishing line broken,It can avoid fishing line by protector to be truncated,Not only the fish of Hook is not easy to escape Shang Shi,Increase the confidence of rodman,Qie Yu Hook,The probability that false bait is truncated can reduce,The money expenditure for liking rodman is relative reduction.本創作係關於一種魚線防護件，該防護件為上窄下寬之錐狀型態，於防護件內部形成由上至下貫通之通孔，並於底端形成側向連通之穿槽，穿槽與通孔貫通形成魚線容置空間，並於穿槽處形成定位部，魚線可自防護件頂端之通孔處穿入後繫固一扣環，扣環底端再繫固魚鈎及假餌，且使扣環限位於定位部處而不會掉出防護件底端，藉此使防護件位於魚鈎、假餌被晃動時光波水影最大處，當魚上鈎而擬咬斷魚線時，藉由防護件可避免魚線被截斷，不僅使上鈎的魚不易逃脫，增加垂釣者之信心，且魚鈎、假餌被截斷的機率即會降低，喜好垂釣者的金錢支出即相對降低。
