Network cable pay-off device

A network cable pay-off device relates to a data center network cable laying device, and comprises a winding cylinder used for winding a network cable, hand-held handles fixedly arranged at two end parts of the winding cylinder, and a plurality of groups of stretching supports arranged on the winding cylinder and used for tensioning the network cable, and each stretching support is driven by an elastic member to maintain a stretching trend. The length of each stretching support is the same as that of the winding cylinder, the elastic pieces are symmetrically arranged on the inner sides of the two ends of each stretching support, and the stretching supports are of a central symmetry structure relative to the axis of the winding cylinder. When large-batch comprehensive wiring operation is carried out, one-person operation can be achieved without worries, the network cables flattened by using the tool can be naturally parallel, and most radian presentation is reduced. 一种网线放线器，涉及数据中心网线敷设装置，包括用于卷绕网线的绕线圆柱、固定设置在所述绕线
