[0008] The needle head part with special shape comprises a needle head, the outside of the needle head comprises several inclined surfaces and arc surfaces.
[0009] The inclined surfaces are provided with two, and the two inclined surfaces are respectively adjacent to the arc surfaces.
[0010] The flow guide structure comprises a flow guide groove arranged on one side of the needle hole, and the outside of the needle hole is provided with a round corner.
[0011] As a preferred scheme of the utility model, the outside edge of the edge groove has a chamfer.
[0012] As a preferred scheme of the utility model, the outside edge of the needle body is further provided with several reinforcing grooves.
[0013] Compared with the prior art, the utility model has the beneficial effects that:
[0014] The utility model discloses a needle head part is set to special shape, and the special shape needle head part can increase the penetration of cloth, reduce the resistance that fabric receives, avoid the situation of needle jumping when using, avoid damaging cloth, and the setting of flow guide structure can make needle thread can pass smoothly.

[0020] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.
[0021] In order to facilitate the understanding of the utility model, the utility model will be described more fully below in conjunction with relevant. Several embodiments of the utility model are given. However, the utility model can be realized in many different forms, and is not limited to the embodiments described in this paper. On the contrary, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and comprehensive.
[0022] It should be noted that when an element is referred to as "fixed to" another element, it can be directly on another element or there can be a middle element. When an element is considered to be "connected" to another element, it can be directly connected to another element or there can be a middle element. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this paper are only for illustrative purposes.
[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description herein is for describing particular embodiments only and is not intended to be limiting of the application. The use herein of the terms "including", "comprising", "having" and the like are specifically intended to be construed in an inclusive sense and not to the exclusion of any other items.
[0024] Please refer to Figures 1-4 The application provides a technical scheme:
[0025] Embodiments, please refer to Figure 1 、 2 , 3 and 4, a needle head of a needle jumping prevention sewing machine, comprising a needle body 1, the needle body 1 is provided with a needle handle 2 and a needle head structure at both ends respectively, the needle head structure comprises a needle head part in a special shape, a side close to the needle head part is provided with a side groove 5, and a needle hole 7 for the needle thread to pass through is arranged in the inside of the side groove 5, and a flow guide structure is arranged outside the needle hole 7, so as to facilitate the smooth passing of the needle thread, the needle head part in a special shape comprises a needle head 3, the outside surface of the needle head 3 comprises a plurality of inclined surfaces 4 and an arc surface, the two inclined surfaces 4 are respectively adjacent to the arc surface.
