Embodiment Construction

[0017] The invention will be further introduced below in conjunction with the drawings and specific embodiments.

[0018] Such as Figure 1~3 As shown, a manual wire feeding mechanism includes a wire pulling piece 1 and a rotating shaft 2. The pulling piece 1 is provided with two wire pulling holes 3, the rotating shaft 2 is rotatably connected to the body 4, and one end is fixedly connected To the side of the cable piece 1, the other end is fixedly connected with the shake handle 5. After passing the thread 14 through the first hole on the front side of the cable piece, pass the second hole on the outside of the cable piece 1, and rotate the rotating shaft , The thread can be pulled forward, so that after the keyhole is completed, a section of thread is reserved for easy cutting.

[0019] Preferably, the above-mentioned cable pulling piece 1 has a bent L-shaped structure, and the structure is simple, and the above-mentioned two cable holes 3 are arranged vertically in a line, and...

Abstract

The invention discloses a manual wire feeding mechanism, which comprises a wire puller and a rotating shaft. The wire puller is provided with two wire hole. The rotating shaft is rotatably connected to the machine body, and one end is fixedly connected to one side of the puller. The other end is fixedly connected with a rocking handle. The rocker handle of the present invention drives the rotating shaft, and the rotating circle drives the wire piece to rotate, so that the wire on the wire piece is sent forward to a section of the reserved length, which is convenient for cutting the keyhole after completion, and effectively solves the reserved length existing in the prior art The technical problem of inconvenient cutting caused by insufficient cutting, and also has the characteristics of simple structure, convenient operation and use, loading and unloading maintenance, and energy saving.

Description

Technical field [0001] The invention belongs to the technical field of sewing machines, and specifically relates to a manual thread feeding mechanism. Background technique [0002] The existing buttonholing machine needs to send the thread to the needle to reserve a certain length after the buttonhole is completed, and the motor drives the connecting rod to realize the thread feeding. However, the existing buttonholing machine often leads to insufficient thread feeding length. , It is inconvenient to cut with scissors, and it is easy to cause the problem of disconnection, and increases the complexity and energy consumption of the equipment. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a buttonhole machine manual wire feeding mechanism with simple structure, convenient operation and use, convenient wire feeding, and long enough reserved length in view of the above-mentioned problems in the prior art. [0004] The technic...
