The invention relates to electric wire winding equipment, in particular to an electric wire winder, which has a fixed-post structure, can almost adapt to any external direction and is used for tightly connecting bundles of electric wires and statically and stably conducting current. The electric wire winder consists of a base module and a locking hoop module, and comprises dozens of parts such as a retaining post seat, a limiting screw, a spring inner sleeve, an elastic jacking bush, a sliding barrel cap, a sliding barrel, a locking hoop spring and a locking hoop bolt. The defects of single wire winding direction, excessively small wire winding quantity, lead looseness, unstable current conducting performance and the like in a current well-known electric wire winder are overcome, and a unique fixed-post multi-direction electric wire winding device is provided for people. Apart from the function of conducting current among a plurality of strands of electric wires of well-known electric wire winding equipment, the electric wire winder further has the beneficial effects of extensive connection, compact connection, static and stable conduction, wide use and the like. Moreover, the electric wire winder is easy to implement, and is easy to manufacture. A formed product is attractive, elegant, firm and durable, and has a wide market space and high practical value and economical added value.
