Sewing machine and thread stand thereof

Abstract

The invention discloses a thread stand of a sewing machine. The thread stand comprises at least two pay-off devices and connecting devices, wherein the at least two pay-off devices are respectively used for accommodating wound upper threads (12) and accommodating wound bottom threads (13); the connecting devices are used for connecting the pay-off devices and the sewing machine. By utilizing the connecting devices, the pay-off devices are installed on a machine body of the sewing machine, that is, the thread stand is installed on the machine body of the sewing machine. The thread stand is simple in structure, and is convenient to install; the existing installation mode is changed, the thread stand is close to users; threads are relatively convenient to change and adjust, and the thread stand is convenient to operate by users, and is fixedly connected so as to prevent from being knocked off effectively, and further the working efficiency is improved. The invention also discloses the sewing machine comprising the thread stand.

Description

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

In the prior art, most of the thread racks are complex in ...

AI Technical Summary

Problems solved by technology

In the prior art, most of the thread racks are complex in structure, cumbersome to install, and occupy a large space. Great inconvenience and reduced work efficiency

Some wire racks are placed directly on the table or the ground without good fixing measures. They are easy to be knocked down during the work process, causing damage to the wire racks and creating obstacles for users, which also lowers work efficiency.
