A kind of winder, including shell and coil holder, shell have the first shell and second housing. First shell has the first opening and the first half string holes, and the first half string holes are to set the side of the first shell of what. Second housing is combined with the first shell to constitute accommodation space, and second housing has the second opening and the second half string holes, and the first, second opening is connected with accommodation space, the second half string holes and the first half string holes the first string holes of formation. Coil holder installs what accommodation space and can have hollow open with respect to what housing into rotation, coil holder, and the first, second opening is interconnected with hollow open. When coil holder is with respect to housing into rotation, one end of wire rod can submerge accommodation space from the first string holes and wind on what coil holder. This creation cooperates different wire rods by simple structure to realize the effect of a variety of applications.一種捲線器，包括殼體及線架，殼體具有第一外殼及第二外殼。第一外殼具有第一開口及第一半線孔，且第一半線孔是設於第一外殼之側面。第二外殼與第一外殼相結合以構成容納空間，第二外殼具有第二開口及第二半線孔，且第一、第二開口與容納空間相連通，第二半線孔與第一半線孔形成第一線孔。線架裝設於容納空間並可相對於殼體轉動，線架具有中空開口，且第一、第二開口與中空開口互相連通。當線架相對殼體轉動，線材的一端會自第一線孔沒入容納空間並捲繞於線架上。本創作藉由簡單構造，並配合不同線材來實現多種應用的效果。
