Both ends be provided with the second magnetic sheet, the inside of the side lengthened plate is additionally provided with holding tank.
As a kind of optimal technical scheme of the present utility model, one end of the warp passes through threading hole and the outer rotating shuttle
Connection, the one ends wound of the parallel is on interior rotating shuttle.
As a kind of optimal technical scheme of the present utility model, four spacer pins are additionally provided with the feed dog.
As a kind of optimal technical scheme of the present utility model, the thickness of the holding tank is more than the thickness of the main lengthened plate
Degree.
As a kind of optimal technical scheme of the present utility model, the main lengthened plate and the side lengthened plate are stretched with described
Contracting groove is slidably connected.
The beneficial effect that the utility model is reached is：The device is needle line sewing structure, and the device can lead to
The expansion plate crossed inside feed dog realize the structure of feed dog increase, so as to adjust needlework weaving fine and closely woven degree, whole device
It is reasonable in design, it is easy to use, solve existing sewing machine mainly by shank and feed dog linkage to be spun to cloth
Knit, but the size of feeding tooth is fixed, it is difficult to the problem of adjusting the fine and closely woven property of cloth.

Embodiment
Preferred embodiment of the present utility model is illustrated below in conjunction with accompanying drawing, it will be appreciated that described herein excellent
Select embodiment to be merely to illustrate and explain the utility model, be not used to limit the utility model.
Embodiment 1
As Figure 1-3, the utility model provides needle line sewing structure, including some feed dogs 1, some work feeds
The surrounding of tooth 1 is wound with warp 2 and parallel 3, and the top of feed dog 1 is provided with shank 6, threading hole 7 is provided with shank 6, is sent
The bottom of dog 1 is provided with outer rotating shuttle 4, and outer rotating shuttle 4 is internally provided with interior rotating shuttle 5, and the surrounding of feed dog 1 is provided with flexible
Groove 8, the top and bottom of telescopic chute 8 are provided with main lengthened plate 10, and the both sides of telescopic chute 8 are provided with side lengthened plate 11, main lengthening
