1. A horizontal-axis sewing thread output structure, for use in a textile sewing machine, wherein the textile sewing machine is provided at least with a sewing thread supplying portion where a sewing thread bobbin is mounted or placed, the horizontal-axis sewing thread output structure being characterized by comprising a stator portion, a rotor portion, and a fixing portion, wherein:
the stator portion is fixed to the sewing thread supplying portion and is provided with a horizontally extending stator shaft;
the rotor portion is coupled to the stator portion and includes a rotating member configured to be rotated about an axis defined by the stator shaft, wherein the rotating member has an end located away from the stator shaft and configured to be inserted into the sewing thread bobbin such that the sewing thread bobbin is mounted on the rotating member and is rotatable via the rotating member about the axis defined by the stator shaft;
the fixing portion includes a first positioning member and a second positioning member, both configured to fix the sewing thread bobbin in position, the first positioning member is provided at an end of the rotating member that is adjacent to the stator shaft, the first positioning member is configured to abut against a tail portion of the sewing thread bobbin, the second positioning member is detachably joined to the rotating member and is at an end of the rotating member that is located away from the stator shaft, and the second positioning member is configured to abut against a head portion of the sewing thread bobbin; and
the first positioning member and the second positioning member are able to clamp the sewing thread bobbin in position such that the sewing thread bobbin is fixed on the rotating member horizontally and, when outputting a sewing thread, is rotatable in a natural manner via the rotating member about the axis defined by the stator shaft;
wherein the rotor portion is coupled to the stator portion via at least one bearing;
wherein the rotating member is bar-shaped and is formed therein with a hollow portion to allow the rotating member to be mounted on and around the stator shaft, with an inner surface of the hollow portion of the rotating member coupled to the stator shaft via the at least one bearing; and
wherein the at least one bearing includes an inner ring and an outer ring, the inner ring and the outer ring are rotatable with respect to each other, the inner ring is joined to a surface of the stator shaft, and the outer ring is joined to the inner surface of the rotating member.
