[0028] Please see Figure 1-3This utility model provides an embodiment of a glue-free coil structure: A glue-free coil structure includes an inner core 1, adjusting rings 2 located at both ends inside the inner core 1, and multiple sets of mounting screws 3 located outside the inner core 1. The inner core 1 includes: a hollow slot 101 located at the middle position inside the inner core 1, and multiple sets of movable slots 102 extending into the hollow slot 101 are provided on the outer side of the inner core 1; and wire groups 103 are provided on the outer side of the inner core 1.

[0029] Please refer to this carefully. Figure 2 and Figure 3 Multiple limiting blocks 201 are provided on the outer side of the two sets of adjusting rings 2, which penetrate into the interior of the movable groove 102. The limiting blocks 201 and the inner core 1 can move through the movable groove 102. One side of each end of the inner wall of the empty groove 101 is provided with a fixing block 202. A bidirectional screw 203 is provided between the two sets of fixing blocks 202, which penetrates into the interior of the two sets of adjusting rings 2. The two sets of bidirectional screws 203 can be used to adjust the two sets of adjusting rings 2 downward. One end of the bidirectional screw 203 is provided with a rotating block 204, which facilitates the adjustment of the bidirectional screw 203. The other side of each end of the inner wall of the empty groove 101 is provided with a fixing block 205. A limiting rod 206 is provided between the two sets of fixing blocks 205, which penetrates into the interior of the two sets of adjusting rings 2. The limiting rod 206 makes the adjustment of the two sets of adjusting rings 2 more stable.

[0030] Please refer to this carefully. Figure 1 and Figure 2 Locking nuts 302 are provided on the outer sides of both ends of the mounting screw 3. The inner side of the limiting block 201 away from the adjusting ring 2 is provided with mounting holes 301. The mounting screw 3 can be installed inside the limiting block 201 through the mounting holes 301, and the locking nuts 302 can limit the movement between the mounting screw 3 and the limiting block 201, which facilitates the installation and fixing of the wire assembly 103.

[0031] Please refer to this carefully. Figure 2 and Figure 3Two sets of adjusting rings 2 are movably connected to the inner core 1 through slots 101. The slots 101 allow the adjusting rings 3 and inner core 1 to move, facilitating adjustment of the adjusting rings 2. Four sets of mounting screws 3 are provided. The screw group 103 is detachably connected to the inner core 1. One end of the limiting block 201 is welded to the outer side of the adjusting ring 2. The limiting block 201 is movably connected to the inner core 1 through a movable slot 102, allowing movement between the limiting block 201 and the inner core 1. One end of each of the two sets of fixing blocks 202 is welded to the inner wall of the slots 101. A bearing is provided on one side of one set of fixing blocks 202, and one end of the bidirectional screw 203 extends into the bearing. One end of the bidirectional screw 203 is rotatably connected to one set of fixing blocks 202 through the bearing. The bearing makes the rotation of the bidirectional screw 203 more stable, facilitating adjustment of the adjusting ring 2. The first fixing block 202 has a rotating hole inside. The other end of the bidirectional screw 203 is rotatably connected to the other fixing block 202 through the rotating hole. The rotating block 204 is welded to one end of the bidirectional screw 203 to make the rotation of the bidirectional screw 203 more stable. Both sets of adjusting rings 2 have limit holes inside, and the limit rod 206 passes through the limit hole. Both sets of adjusting rings 2 are slidably connected to the limit rod 206 through the limit hole. The limit hole allows the adjusting ring 2 to slide with the limit rod 206, making the adjustment of the adjusting ring 2 more stable. Both sets of adjusting rings 2 have threaded holes inside that match the bidirectional screw 203. The two sets of adjusting rings 2 are threadedly connected to the bidirectional screw 203 through the threaded holes to achieve the effect of limit adjustment. The rotation of the bidirectional screw 203 can adjust the two sets of adjusting rings 2 downwards, which facilitates the limit installation of the wire assembly 103.

[0032] Please refer to this carefully. Figure 1 and Figure 3 The mounting screw 3 is detachably connected to the limiting block 201 through the mounting hole 301. The mounting screw 3 can be installed inside the limiting block 201 through the mounting hole 301. The locking nut 302 has a threaded hole that matches the mounting screw 3 inside. The locking nut 302 is detachably connected to the mounting screw 3 through the threaded hole. The locking nut 302 can limit the distance between the mounting screw 3 and the limiting block 201, resulting in better fixation of the wire assembly 103.

[0033] Working Principle: In use, the thread set 103 is wound around the outside of the inner core 1. Manually rotating the rotating block 204 drives the bidirectional screw 203 to rotate. The positive and negative threads on the outside of the bidirectional screw 203 engage with the threads inside the two sets of adjusting rings 2, allowing the two sets of adjusting rings 2 to be adjusted downwards. The limiting holes allow the two sets of adjusting rings 2 to slide against the limiting rod 206, making the adjustment of the two sets of adjusting rings 2 more stable. The movable groove 102 allows the limiting block 201 to move relative to the inner core 1. The limiting block 201 on the outer side of the adjusting ring 2 limits both ends of the wire group 103. Then, the mounting screw 3 is passed through the mounting hole 301 and the locking nut 302 is installed on both ends of the mounting screw 3 through the threaded hole. The locking nut 302 limits the mounting screw 3, so that the mounting screw 3 can be installed on one end inside the limiting block 201. By limiting the wire group 103 with four sets of mounting screws 3, the wire group 103 can be fixed to the outer side of the inner core 1 without glue, so that the coil can be used better.
