Abstract

The invention relates to the technical field of sewing machines, and discloses a shuttle assembly of a sewing machine. The shuttle assembly comprises a shuttle sleeve and a rotary shuttle, a positioning block is arranged on the side of the shuttle sleeve, a positioning groove matched with the positioning block is arranged in an inner shuttle rack, a first connector is arranged at the bottom of aninner cavity, a second connector is arranged at the bottom of the shuttle sleeve, and the shuttle sleeve is detachably connected through the first connector and the second connector. Based on the above, during mounting the shuttle sleeve and the inner shuttle rack of the rotary shuttle are positioned through one positioning block, the shuttle sleeve is placed in the inner shuttle rack and is fixedly connected just through the first connector inside the inner cavity and the second connector at the bottom of the shuttle sleeve; the first connector and the second connector are arranged inside theinner cavity and at the bottom of the shuttle sleeve, so that the size of the shuttle sleeve and of the inner shuttle rack can be avoided being increased, and the integrity of the shuttle assembly isguaranteed; adjusting one positioning structure is just required for mounting and demounting; operating is simple, using is facilitated, time and labor are saved, and sewing efficiency of the sewingmachine is greatly improved.

Description

technical field [0001] The invention relates to the technical field of sewing machines, in particular to a sewing machine shuttle assembly.
