Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining
The utility model, it is not used to limit the utility model.
Referring to Fig. 1-6：A kind of flat seam machine big needle distance feed mechanism, including cloth feeding mechanism 5, cloth pushing shaft 3, lift last item 4, institute
The cloth pushing shaft 3 stated and the right side of lift last item 4 are connected with cloth feeding mechanism 5, it is characterised in that：Also include needle plate 1, regulation crank 6, tooth
Frame 7, crank of tooth frame 8, connecting rod 1, feed lifting fork 12, connecting rod crank 13 and connecting rod 2 14；
Referring to Fig. 3：The described structure of crank of tooth frame 8 be by support bar it is integrally formed be connected to it is upper on cylindrical circumference
Hold two roundlet pylons and the roundlet pylon of lower end one；
