发明名称 METHOD OF USING A CORD HOLDER
摘要 The method is for using a cord holder. A cord holder has a bottom cover and a removable top cover with a spring bracket disposed therebetween. The removable top cover is removed from the bottom cover without removing a spring from a spring bracket so that the spring remains in the spring bracket and the bottom cover while the top cover is removed. A cord is placed around a first spacer and a second spacer of the spring bracket. A knob is pressed to permit a spring, disposed inside the spring bracket, to roll up the cord.
