| Zusammenfassung: | The utility model discloses a stepped wire coil supporting structure which comprises a pay-off lever and a wire coil, the pay-off lever penetrates through a middle hole of the wire coil, stepped wire coil supporting sleeves are symmetrically arranged at the two axial ends of the wire coil, the stepped wire coil supporting sleeves are arranged on the pay-off lever in a sleeving mode, and the stepped wire coil supporting sleeves are fixed through clamps on the outer sides of the stepped wire coil supporting sleeves; a plurality of steps with height difference are arranged on the stepped wire coil supporting sleeve, and the stepped wire coil supporting sleeve extends into the middle hole of the wire coil through the step matched with the middle hole diameter of the wire coil. According to the utility model, the stepped wire coil supporting sleeve is only acted by radial force in the use process, so that the system stability is stronger, the situation that the supporting sleeve deforms and is blocked is avoided, |
