In preferred embodiment of the utility model, comprise that further described blade edge edge only is provided with cutting edge in a place, described cutting edge is positioned at middle part, the described edge of blade.
In preferred embodiment of the utility model, comprise that further described blade edge edge only is provided with cutting edge in a place, described cutting edge is positioned at blade near the connecting rod place.
In preferred embodiment of the utility model; comprise that further described blade is provided with protective sleeve; described protective sleeve is a flexure strip; be close to blade face by blade away from a side of base plate along the direction that is parallel to described connecting rod side extend to blade edge along after; walk around described edge and extend to the side that blade is bordering on base plate; described protective sleeve is top at blade away from the part of base plate one side, and the part that is bordering on base plate one side at blade is the bottom, and the part that connects the upper and lower is connecting portion.
In preferred embodiment of the utility model, comprise that further the minimum range of described protective sleeve upper and lower equals described blade thickness.
In preferred embodiment of the utility model, further comprise described protective sleeve upper and lower perpendicular to the length of described cutting edge bearing of trend greater than the width of described cutting edge perpendicular to self bearing of trend.
The utility model has solved the defective that exists in the background technology; be combined with the tangent line blade on the sewing-machine foot of the present utility model; the setting of blade is convenient the use both; hidden and difficult injury operator points again; at blade movably elastic protecting sleeve is set in addition, the blade in the non-use is played a barrier action, further improve security; and loading and unloading freely, and are practical flexibly.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of preferred embodiment of the present utility model;
Fig. 2 be part shown in Figure 1 protective sleeve be overlying on the non-blade port blade edge along the time enlarged diagram;

The specific embodiment
In conjunction with the accompanying drawings and embodiments the utility model is described in further detail now, these accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As Figure 1-3, but a kind of tangent line sewing-machine foot of the present utility model, described presser feet comprises laterally extending base plate 1 and is located at vertical upwardly extending connecting rod 3 on the base plate 1, described connecting rod 3 comprises two sides parallel with base plate 1 bearing of trend, described base plate 1 comprises the front end that is provided with pin hole or crosses pin breach 11, the other end is the rear end, a described connecting rod side 31 is provided with the blade 2 perpendicular to this side 31, described blade 2 is arranged with strip shape cutting edge 21 near a side of base plate 1 rear end along 22 tops, and described cutting edge 21 extends in the same way with described edge 22.Described blade 2 edges 22 only are provided with cutting edge 21 in a place, and described cutting edge 21 is positioned at blade 2 near connecting rod 3 places.Described blade 2 is provided with protective sleeve 4; described protective sleeve 4 is a plastics n shape flexure strip; described protective sleeve 4 is close to blade 2 surfaces and is extended to blade edge along 22 after away from a side of base plate 1 along the direction that is parallel to described connecting rod side 31 by blade 2; walk around described edge 22 and extend to the side that blade 2 is bordering on base plate; described protective sleeve 4 is top 41 at blade 2 away from the part of base plate 1 one sides; the part that is bordering on base plate 1 one sides at blade 2 is bottom 42, and the part that connects top 41 and bottom 42 is connecting portion 43.The minimum range that described protective sleeve top 41 and bottom are 42 equals described blade 2 thickness.Described protective sleeve top 41 and bottom 42 perpendicular to the length of described cutting edge 21 bearing of trends greater than the width of described cutting edge 21 perpendicular to self bearing of trend, protective sleeve 4 along the length of cutting edge 21 bearing of trends more than or equal to these direction cutting edge 21 length.
According to usual way in the industry the utility model presser feet is installed, the presser feet front end face is to the operator, described cutting edge 21 is back to the operator, during tangent line, upper thread is walked around cutting edge 21 places backward by the eedle place pull forward, cut off upper thread, because cutting edge 21 is near connecting rod side 31, be in the difficult zone that touches of operator's finger, comparatively safe.During sewing, described elastic protecting sleeve 4 is moved to the cutting edge position, cutting edge is placed in top 41, bottom 42 and the connecting portion 43 formed spaces of protective sleeve 4, be protected.Not only ensure operator's safety, also protected blade to be difficult for oxidation and rusting.Again protective sleeve 4 is moved to do not put the first edge on a knife or a pair of scissors mouthful 21 places, next door during use, make things convenient for secant.
Above foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related personnel can in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.The technical scope of this utility model is not limited to the content on the specification, must determine technical scope according to the claim scope.
