By adopting technique scheme, when needs are used bilateral presser feet, by the first groove fit on the projection on main presser feet and time presser feet, elastic clamping block is extruded and is stuck in the draw-in groove of time presser feet, the engagement limits of projection and the first groove the movement of inferior presser feet perpendicular direction, elastic clamping block coordinates with draw-in groove, limited the movement of inferior presser feet horizontal direction, omnibearing so inferior presser feet and main presser feet are fixed, good stability and installation, dismantle very convenient quick, when needs are used monolateral presser feet, only need inwardly promote being positioned at time push rod end in presser feet outside, push rod is released draw-in groove by elastic clamping block, just inferior presser feet can be separated, simple and convenient quick, realized the quick-replaceable of two presser feets and single presser feet, enhance productivity.
The utility model is further set to: the two ends of described push rod are equipped with stop part, and described stop part size is greater than groove.
By adopting technique scheme, push rod two ends stop part size is greater than groove size, can effectively guarantee that like this push rod can not drop out and affect result of use from groove, push rod always in groove, faster and more convenient operation.
The utility model is further set to: described main presser feet is all arranged with the leather packing of joining and by elastomeric material being made similar to it with time presser feet bottom, described main presser feet and time presser feet side are equipped with the second groove around its surrounding, and described leather packing is provided with the projection with the second groove fit.
By adopting technique scheme; elastomeric material has certain elasticity, not only can effectively protect the fabric that quality is thinner like this, also has certain damping effect; increased the service life of presser feet; leather packing fastens by projection and the second groove, and stable connection, is not prone to and drops and be offset like this; leather packing can also be changed according to abrasion condition; owing to thering is elasticity, when not needing leather packing or changing, can directly it be deviate from from main presser feet and time presser feet, simple and fast is convenient.
