A line extender and rewinder for a kite comprising a main body, a connector, a spring leaf, a jacket, a column and a wedge body. The main body has a passing hole, a flange, holes, and segment line winding seats and recessions. The flange is at a side of the passing hole, and has a toothed slot. The segment has a slot and curved groove on it. The connector has a hollow post at one end, a moving rod at another end, and a ring in the middle. The hollow post has a recession at one end and a threaded inner surface at the other end. The moving rod has two blocks at one end to facilitate passing through the passing hole at the main body, and a recession at another end. The spring leaf is made of bent steel wire with two protuberances on it. The column has an end with a ball. The spring leaf is loaded within the connector, which is then connected to the jacket and caused to pass through the passing hole of the main body so that the blocks at the moving rod are at another side of the main body. The wedge block is inserted into the V-slot formed by the blocks. A protuberance of the spring leaf passes through the recession of the main body and is held within the toothed slot at the flange of the main body while another protuberance is held within a recession at the connector.
