As a further improvement, a chamfer is arranged at the intersection of the end face of the positioning block and the first inclined plane.
As a further improvement, the concave surface groove is a concave arc surface groove which is arranged along the axial projection of the rotating shuttle.
As a further improvement, the axial lead of the concave cambered surface groove is parallel to the axial lead of the rotating shuttle.
As a further improvement, the axis of the arc where the concave arc groove is located and the axis of the rotating shuttle are concentrically arranged.
As a further improvement, the upper side surface of the working end of the positioning hook body is provided with a groove which penetrates through the positioning hook body. The groove is obliquely arranged towards the embroidery needle. The two sides of the working end of the positioning hook body, which are positioned at the groove, are provided with the convex blocks extending upwards, and the grooves are formed between the convex blocks extending upwards at the two sides.
Compared with the prior art, the utility model, its beneficial effect is, the face relative with the rotating shuttle axis on the location hook body, correspond the department with the rotating shuttle at least and be equipped with the concave surface groove, the artificial or automatic bobbin case cop latch that trades of can being convenient for of concave surface groove. In addition, the arrangement of the groove can facilitate the use of the rotating shuttle with larger capacity, and improve the service time of sewing and embroidering equipment.
The first inclined plane is further arranged on one side, facing the rotating shuttle axial lead, of the positioning block, so that the upper thread can be better passed, the first inclined plane can effectively enable the upper thread to be rapidly separated, abrasion in the upper thread separating process is effectively reduced, and the thread breakage probability of the upper thread to be separated is reduced.

Detailed Description
Referring to fig. 1-8, in the present embodiment, a rotating shuttle positioning hook structure includes a positioning hook body 1, one end of the positioning hook body 1 is a connecting end 2, and the connecting end 2 may be provided with a connecting hole or/and a groove, and is generally fixedly connected to a corresponding position of a sewing device by a screw for fixing the positioning hook body 1 to be matched with a rotating shuttle. The other end of the positioning hook body 1 is a working end 3, and the working end 3 is usually positioned at a rotating shuttle port. The positioning hook body 1 is provided with a protruding positioning block 4, and the positioning block 4 is usually arranged at a corresponding position of the working end 3 to be matched with an inner shuttle opening of the twist lock so as to position the inner shuttle. One side of the positioning block 4 facing to the shaft axis of the rotating shuttle is provided with a first inclined plane 41, and the arrangement of the first inclined plane 41 can facilitate the thread taking-off of the upper thread.
The positioning block 4 is provided with an end face 42 at the inner side matched with the rotating shuttle, and the end face 42 is intersected with the first inclined face 41. The end face 42 is provided to ensure that the positioning block 4 can be quickly and accurately matched with the rotating shuttle port.
And a chamfer is arranged at the intersection of the end surface 42 of the positioning block 4 and the first inclined surface 41.
In order to facilitate the installation of the rotating shuttle, a concave groove is arranged on the surface of the positioning hook body 1, which is opposite to the axis of the rotating shuttle, at least at the position corresponding to the rotating shuttle, and the concave groove is arranged along the axial projection of the rotating shuttle. The concave grooves may be concave arc grooves or concave groove surfaces, or irregular concave grooves. The concave groove may be provided only at a position corresponding to the rotary hook, or may be provided much larger than the rotary hook at a position corresponding to the positioning hook body 1. The concave groove is arranged to facilitate manual picking or automatic replacement of the bobbin case.
In this embodiment, a concave arc groove 11 is provided on a surface of the positioning hook body 1 opposite to the axis of the rotating shuttle, at least at a position corresponding to the rotating shuttle, and the concave arc groove 11 is arranged along the axial projection of the rotating shuttle.
In this embodiment, preferably, the axial line of the concave arc groove 11 is parallel to the axial line of the rotating shuttle, so as to facilitate installation and removal of the rotating shuttle, even to install the rotating shuttle with a capacity greater than a conventional capacity.
