AI Technical Summary
In existing sewing machines, presser foot pressure adjustment and switching is more troublesome, especially in different usage situations, it cannot be generalized and inconvenient to operate.
A presser foot with switchable pressure is designed. By setting an adjustment structure on the rod core, including an adjustment assembly and a return spring. The adjustment assembly adjusts the compression amount of the return spring through the coordination of the guide sleeve, ratchet and plunger member, thereby changing the elastic pressure of the presser foot and achieving different pressure states on the seam material.
It realizes convenient switching of presser foot pressure, is suitable for different usage situations, and improves the practicality and convenience of the sewing machine.
