To achieve the above object, the technical solution of the utility model is as follows：
A kind of elastic presser feet, including cover plate connecting seat, guide pin bushing and support bar, the guide pin bushing are connected to the cover plate connection
The lower end of seat, the upper end of the support bar is placed on the inside of the guide pin bushing, boss is provided with the middle part of the support bar, described to lead
Be disposed with first group of disc spring and second group of disc spring between the lower end of set and the boss, and first group of disc spring and
Second group of disc spring is placed on the outside of the support bar, and the guide pin bushing is internally provided with packing ring, and the packing ring is connected to institute
State the upper end of support bar；First group of disc spring and second group of disc spring form buffering section, first group of disc spring and the
When two groups of disc springs are compressed, the support bar rises along the guide pin bushing, when first group of disc spring and second group of disc spring reset,
The support bar declines along the guide pin bushing, and the packing ring is used for the spacing of the support bar, avoids coming off for the support bar.
Preferably, the upper end of the cover plate connecting seat is provided with connecting screw, the connecting screw is connected with the cover plate
Seat is integrally formed, and the connecting screw is used for the installation of presser feet, easy to use.
Further, the lower end of the support bar is connected with pressure head, and the pressure head is brass pressure head, and material is softer, effectively
Workpiece surface is avoided to produce impression.
Further, the tapered direction of first group of disc spring and the tapered direction of second group of disc spring are on the contrary, increase
Cushion stroke, strong shock resistance.
The beneficial effects of the utility model are：(1) by setting first group of disc spring and second group of disc spring to form buffering area
Between, impulsive force of the presser feet during pushing is reduced, noise is small, long lifespan, safe and reliable；(2) replaceable pressure is set
Head, and the material of pressure head is softer, avoids workpiece surface from producing impression, improves the quality of product；(3) connecting screw is set, made
It is more convenient to obtain the installation of presser feet, it is easy to use.
【Brief description of the drawings】
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only
