Problems solved by technology

[0003] But although this upper hook thread device 74 can make the next sewing without residual thread ends, there is still a small deficiency in use, because the hook piece 741 of the upper hook thread device 74 utilizes its reed 742 to clamp the cut car. During sewing thread 711, have considerable distance from car needle 71 [as Figure 15 As shown in L], the remaining thread ends 710 are only about 4 to 5 mm left at the clamping end; when the needle 71 pierces the fabric downwards to make the netting, the remaining thread ends 710 will quickly break away from the clamping end However, due to natural fall, when sewing, the hooker under the working platform cannot be hooked and formed, resulting in three to four needles, or even more than four needles.

Embodiment Construction

[0022] In order to make the technical content, the purpose of the invention and the effects achieved by the invention more complete and clear, the preferred embodiments of the invention will be described in detail below with reference to the accompanying drawings:

[0023] First, see figure 1 , 2 As shown, it is a schematic diagram of assembly and disassembly of the thread hooking device of the sewing machine of the present invention. The thread hooking device A is arranged adjacent to the needle B1 of the sewing machine B and adjacent to the needle B1. It is mainly composed of a driving element 11 The main base body 1, the linkage member 2 provided with the wire hook element 24, the first connecting block 3, the second connecting block 4, the lead frame 5 and the wire clamping group 6, wherein:

[0024] See again figure 2 , 3 , The main base body 1 is provided with a through slot 10 to fix a driving element 11, and a swing arm 12 is assembled to the rotating shaft of the driving ...

Abstract

The invention relates to a clipping device of sewing machine that is set beside the pin. Driving component is set on the main seat, arm driving interlock component to move the clipping line component between the guiding base and guiding sheet. The clipping sheet would use the indenting tool to adjust clamping elasticity. It would not cause blank sewing.

Description

Technical field [0001] The invention relates to a thread hooking and clamping device of a sewing machine, in particular to a device for assisting the hooking and clamping of the sewing thread of a sewing machine capable of up and down netting, to drive a connecting piece provided with a thread hooking element to make the thread hooking element Hook the stitching thread into the clip between the upper guide piece and the guide seat to reach the clamping limit of the stitching to facilitate the sewing of the net. Background technique [0002] Three sewing machines commonly seen (such as Figure 10 to 12 As shown], three burs 71 are fixed under the needle seat 7 for sewing up and down to pierce the sewing thread 711, so that the sewing can be sewn like Figure 13 The sewing method shown below has three stitches (commonly known as the chain stitch method) from the bottom of the net to the top; and in order to make the operation more rapid and automatic, a bottom trimming device 75 will...
