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 thread feeding mechanism. The manual thread feeding mechanism comprises a thread drawing piece and a rotating shaft, two thread drawing holes are formed in the thread drawing piece, the rotating shaft is rotatably connected to a machine body, one end of the rotating shaft is fixedly connected to one side of the thread drawing piece, and a crank handle is fixedly connected to the other end of the rotating shaft. The crank handle drives the rotating shaft which drives the thread drawing piece to rotate, so that a thread on the thread drawing piece is sent out for a section with a reservation length forwards, a person can cut the thread short after buttonholing is completed conveniently, the technical problem that in the prior art, due to the fact that the reservation length is not enough, cutting is inconvenient is effectively solved, and the manual thread feeding mechanism further has the advantages of being simple in structure, convenient to operate, use, assemble, dissemble and maintain and capable of saving energy.

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...
