[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. Obviously, the embodiments described are only some embodiments of the present invention, rather than all embodiments.

[0020] Coil threading aids, such as Figures 1 to 4 As shown, it includes a main body, which includes a base 1 and a cross bar 2 connected to the base 1. One end of the cross bar 2 is formed with a positioning groove 21 that can be embedded with an annular material. A deformation wire 3 that slides into a plurality of annular materials is arranged across the positioning groove 21. One end of the deformation wire 3 is elastically connected to the base 1, and the other end of the deformation wire 3 is detachably connected to the base 1. The deformation wire 3 pushes the plurality of annular materials to maintain a relatively fixed position with the main body. In this specific embodiment, the deformation wire 3 is an iron wire with a good deformation effect, that is, the operator can bend the iron wire by bending it, and the replacement cost is low. In order to improve the stability of the deformation wire 3 in the positioning groove 21, when the annular material is embedded in the positioning groove 21, the axis of the annular material is arranged perpendicular to the length direction of the cross bar 2;

[0021] Operation method: When in use, first insert several alloy rings onto the deformed wire 3, and then push the several alloy rings to one side of the positioning groove 21. When starting to thread, first guide the alloy ring closest to the positioning groove 21 to embed into the positioning groove 21. Since the deformed wire 3 is elastically connected to the base 1, the alloy ring in the positioning groove 21 can maintain a fixed position. After threading, slide the alloy ring to the other side of the deformed wire 3, and then operate the next alloy ring into the positioning groove 21. Repeat this process until all the alloy rings on the deformed wire 3 are threaded, then remove the connection between the deformed wire 3 and the base 1, and unload the materials uniformly before loading.

[0022] Practical effect: Through the guidance of the deformable wire 3 and the positioning of the annular material, the time for loading the annular material before positioning and the threading time during positioning are greatly reduced, thereby effectively improving the threading efficiency.

[0023] like Figures 1 to 4 As shown, specifically, the base 1 is fixedly provided with a positioning rod 4, one end of the positioning rod 4 is fixedly connected with a tension spring 6, the other end of the tension spring 6 is fixedly connected to the deformation wire 3, the other end of the positioning rod 4 is detachably connected to the limiting plate 5, the limiting plate 5 is spaced apart from the base 1, and one end of the deformation wire 3 is wound around the positioning rod 4 between the limiting plate 5 and the base 1;

[0024] In order to keep the positions of several alloy rings fixed before threading, the deformation wire 3 slides through the cross bar 2 from one side of the base 1, and the cross bar 2 is formed with a lifting block 22 between the positioning groove 21 and the position where the deformation wire 3 slides through the cross bar 2. The upper end surface of the lifting block 22 is formed with a guide groove 221 for accommodating the deformation wire 3 to slide along it, and the distance between the bottom of the guide groove 221 and the upper end surface of the cross bar 2 is greater than the inner diameter of the annular material. The cross bar 2 is perpendicular to the lifting block 22 and is formed with a support surface that fits several annular materials from the side of the lifting block 22 to the upper end surface in the direction of the positioning groove 21. The cross section of the cross bar 2 from the support surface position to the cross section of the positioning groove 21 position gradually decreases;

[0025] In order to make the threading operation more convenient for the operator, a connecting piece for fixing the angle between the cross bar 2 and the base 1 is provided between the base 1 and the cross bar 2. In this specific embodiment, the connecting piece is a screw and a nut. The screw passes through the base 1 and the screw and is threadedly connected to the nut.
