Guide device of electric spark small hole machine

The utility model provides a guiding device of an electric spark small hole machine. The guiding device comprises a wire supporting assembly and a guiding assembly. The wire supporting assembly and the guiding assembly are arranged at intervals in the conveying direction of the electrode wire. The electrode wire sequentially penetrates through the wire supporting assembly and the guiding assembly. Wherein the wire supporting assembly is used for restraining swinging of the electrode wire during rotation; the guide assembly is used for guiding the electrode wire to a target machining position. According to the guiding device of the electric spark small hole machine, due to the fact that the wire supporting assembly is arranged in the conveying direction of the electrode wire, it can be guaranteed that the electrode wire smoothly penetrates through the guiding assembly when the electrode wire is threaded, swing of the electrode wire during rotation can be limited during machining, and the small hole machining p
