The invention discloses a wire
butt joint device which comprises a gun body and a wire spool, wherein the gun body comprises a
handle, a motor and a winding reel, the end, provided with a rotating shaft, of the motor is connected with the winding reel, the lower end of the motor is connected with the
handle, a battery for supplying power to the motor is arranged in the
handle, and the handle is provided with a winding switch for controlling the motor to rotate forwards and backwards and a reset switch. A wire spool is rotatably connected in the winding reel, the wire spool is connected with a rotating shaft of the motor, wire holes with different diameters are formed in the wire spool, and the number of the wire holes with the same
diameter is at least two. Manpower is saved, and the
operation safety and the working efficiency are improved. Through the cooperation of the wire spool and the winding reel, the uniformity of wire winding is ensured, the
butt joint quality of wires each time is ensured, the aesthetic property and firmness of wire
butt joint are ensured, the complexity of wire connection by hands or by using pliers at present is solved, and the high efficiency and safety of
electric power wire connection are realized.
