Advantageous effects

1. Because the magnet of regulator bottom embedding makes the regulator adsorbed on the platform of sewing machine through magnetic force, and then ensures that the distance between regulator and tool bit or the syringe needle keeps unchangeable in the course of working, realizes that cloth processing width remains unchanged all the time after one side of cloth and regulator are drawn close to neatly, and then has realized that the cloth cutting edge width is unified, also or cuts the orderly effect of line or sewing thread.

2. Owing to set up a plurality of support piece to support piece's material is silica gel, the first magnetic pole face of support piece protrusion magnet, consequently when the regulator is adsorbed on the platform, magnet contactless platform but support piece contact platform, and then has avoided magnet fish tail platform, simultaneously because silica gel's coefficient of friction is big, consequently under the effect of magnetic force, support piece extrusion platform produces great stiction, has avoided the unexpected skew of regulator position in the cloth course of working.

3. Due to the inclined first lug, the first lug has a space towards the projection direction of the first surface, and the space is used for receiving part of fingers of an operator. Therefore, the regulator can be conveniently held and pinched by one hand and moved to any new position from the original position through the one-hand operation, and the regulator can be fixed at any position of the sewing machine platform through the magnetic action of the magnet, so that the distance between the needle head and the regulator is changed, and the free adjustment of the width of the cut edge is realized.

4.
