A kind of improvement that fishnet hanging is restricted again construction is disclosed, includes a hollow nettle, one first counterweight chain and one second counterweight chain. In first counterweight chain and the second counterweight chain accommodating hollow nettle of what, each counterweight chain includes the clump weight of a plurality of equidistant arrangements. Wherein, an interval, the first spacing of one of not small first clump weight of what are kept between the first counterweight chain and the second counterweight chain, so that hollow nettle has the sewing section of caliber diminution naturally. Use reach the fixed multistage counterweight chain of nature with can mechanical sewing what fishing net bottom restrict the effect of.揭示一種漁網垂重繩之改良構造，包含一中空網繩、一第一配重鏈以及一第二配重鏈。第一配重鏈與第二配重鏈容置於中空網繩內，每一配重鏈包含複數個等間距排列之配重塊。其中，第一配重鏈與第二配重鏈之間保持一間隔，不小於第一配重塊之一第一間距，以使中空網繩具有一管徑自然縮小之車縫區段。藉以達成自然固定多段配重鏈與可機械車縫於漁網底繩之功效。
