Binding machine and auxiliary member for binding machine

An auxiliary member for a binding machine wherein the auxiliary member is mounted to a curl guide or to a binding machine main body which supports the curl guide, and the curl guide guides a wire in a loop shape as the wire is fed in a wire feeding direction, wherein

• the auxiliary member has a tapered protrusion that is positioned at an end of the curl guide when it is mounted to the curl guide or the binding machine main body, and at least a portion of the auxiliary member extends downstream from the curl guide with respect to the wire feeding direction,
• wherein the auxiliary member includes a protection part configured to cover at least a part of an outer surface of the curl guide, the protection part including an outer periphery protection surface configured to cover the outer surface of the curl guide, and the outer periphery protection surface extends along a periphery of auxiliary member;
• the auxiliary member including first and second sides spaced from each other in a direction orthogonal to the wire feeding direction when the auxiliary member is mounted on the curl guide or the binding machine main body, and the outer periphery protection surface extends between the first and second sides;
• the tapered protrusion is at a downstream side of outer periphery protection surface with respect to the wire feeding direction;
• and
• the auxiliary member is detachably mountable on the curl guide or the binding machine main body.

A binding machine comprising:

• a curl guide which guides a wire in a loop shape around a binding target as the wire is fed in a wire feeding direction, the curl guide being one of an upper curl guide or a lower curl guide of the binding machine,
• a twisting part which binds the binding target by twisting the wire guided in the loop shape around the binding target, and
• a protrusion which is separate from the curl guide and which is detachably connected to the curl guide or a binding machine main body which supports the curl guide,
• wherein at least a portion of the protrusion is downstream from the curl guide with respect to the wire feeding direction where the curl guide is an upper curl guide or at least a portion of the protrusion is upstream from the curl guide with respect to the wire feeding direction where the curl guide is a lower curl guide,
• wherein the protrusion comprises a protection part configured to cover at least a part of an outer surface of the curl guide from an outside of the curl guide, and
• wherein the protection part has an outer periphery protection surface extending along a periphery of the protrusion with respect to the wire feeding direction and which covers the at least part of the outer surface of the curl guide.
