AI Technical Summary

Technical Problem

Existing sewing machines require the removal of the side cover when changing or adjusting the presser foot bar, resulting in poor maintenance convenience and affecting the efficiency and flexibility of the sewing machine.

Method used

A follow-up presser foot mechanism was designed. By sleeved an adjustment block on the outside of the main rod and using the threaded connection of the screw and the protrusion, the adjustment block can be flexibly adjusted on the main rod. Combined with the design of the threaded block and the lever, the longitudinal position adjustment and replacement of the presser foot rod can be achieved without removing the side cover.

Benefits of technology

It improves the ease of maintenance and adaptability of sewing machines, reduces maintenance costs and time, and enhances the environmental applicability and sewing quality of sewing machines.
