Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with the accompanying drawings and implement
Example, the present invention is further described in detail.It should be appreciated that specific embodiment described herein is used only for explaining
The utility model is not used to limit the utility model.
As depicted in figs. 1 and 2, a kind of sewing machine looper, including needle handle 1, connecting portion 2, shank 3, the second bending section 6 and
Two bending sections 6；The form of sewing machine looper is in " 7 " font, and oxide film layer is covered on sewing machine looper surface.The needle handle 1
It is connect between connecting portion 2 by the second bending section 6, the thickness of second bending section 6 is less than the thickness of needle handle 1.The needle
It is connected between bar 3 and connecting portion 2 by the first bending section 5；3 and second bending section 6 of shank, connecting portion 2 and second are bent
The interior bent face formed between portion 6 is smooth.The needle handle 1 is opposite with 3 centre position of shank, and the flat front end of the shank 3 is in wedge
Shape.The surface setting bar-shaped trough 11 of the shank 3；In the leading inside of shank 3, lug boss 41 is set；Before the lug boss 41
End and lateral bend nature transition in shank 3, there are corners 42 with 3 inside of shank for 41 rear end of lug boss；In the first bending section 5
Screw hole 7 is respectively provided with on the second bending section 6；Two connection perforation 97 are set on the needle handle 1, and 1 end of needle handle is needle stand
Connecting portion 10, setting surrounding covers enhancement layer 12 on the needle stand connecting portion 10, specifically, enhancement layer 12 is frosted enhancement layer
12, it is stayed on needle stand connecting portion 10 and sets link slot 8；As shown in figure 3, the needle stand connecting portion 10 includes internal layer 13 and sandwich layer
