The invention relates to a thread hooking assembly, a rotating shuttle mechanism and a sewing machine. The thread hooking assembly comprises a shuttle race, the shuttle race is rotationally installed in the sewing machine, the shuttle race can rotate with the axis as the center, the shuttle race comprises a first thread hooking part and a second thread hooking part which are arranged in the axial direction, and the thread hooking directions of the first thread hooking part and the second thread hooking part are opposite. According to the thread hooking assembly, the first thread hooking part and the second thread hooking part in different thread hooking directions are arranged, so that the defects caused by an original thread hooking assembly in a single direction are overcome, two sewing stitches with good coincidence can be obtained when the thread hooking assembly is used for forward sewing and backward sewing, and the attractive degree of the sewing stitches is greatly improved.

The invention relates to the technical field of sewing, in particular to a thread hooking assembly, a shuttle hook mechanism, a sewing machine, a sewing method and a lock stitch. The thread hooking piece comprises a first thread hooking part and a second thread hooking part, and the first thread hooking part and the second thread hooking part can be used for thread hooking and thread loosening; the thread hooking parts extend in the circumferential direction of the bearing seat and are formed at different positions of the outer edge of the bearing seat respectively. In one rotation period, the thread hooking assembly can form two needle stitches, the efficiency is higher, the requirement for the rotating speed of the shuttle hook mechanism is lower, and the shuttle hook mechanism with the lower rotating speed is lower in cost and longer in service life; and the same thread hooking assembly can hook and loosen threads bidirectionally, so that the problem of inconsistent inclination directions ...
