[0028] When winding is required, the two wire pressing plates 2 are brought into a close state through external components, and then the magnetic core is placed in the receiving groove 11. The wire feeding structure feeds the two copper wires into the wire feeding groove 12. The copper wire is fed along the wire feeding groove 12 under the constraint of the wire pressing plate 2, and then the copper wire is naturally bent through the arc groove 13 at the end. At the same time, after the copper wire is bent forward, it is further bent and wound around the magnetic core under the guidance of the receiving groove 11 to achieve fast winding. After the set coil value is completed, the wire feeding is stopped, and the copper wire is cut off by an external tool. The external mechanism pulls the wire pressing plate 2 apart, and the magnetic core can be taken out to complete a winding action. In this process, in order to guide more accurately, a movable part 3 is set. When the operating component 4 is started, the movable part 3 moves from the initial position to the predetermined position. At this time, the movable part 3 is connected to the outer side of the arc groove 13 through the slot 31, so that the inner side surface 311 of the slot 31 is aligned with the arc groove 13 and fits on the slot wall of the first movable slot 14, so that the copper wire directly rests on the inner side surface 311 after coming out of the arc groove 13, and at the same time, it can also prevent the copper wire from escaping from the arc groove 13, so that the copper wire is fed in more smoothly, thereby improving the efficiency of feeding. After completing a winding, the operating component 4 is operated to restore the movable part 3 to its original position. At this time, the slot 31 is staggered, and the inner side surface 311 does not correspond to the position of the accommodating slot 11 according to the shape of the copper wire, so it is convenient to remove the magnetic core.

[0029] The base 1 is provided with an arc plate 15 protruding into the first movable groove 14, the arc groove 13 is provided along the arc plate 15, and the arc plate 15 is provided with a first positioning surface 151 for the inner side surface 311 to abut against when the movable member 3 rotates to a preset position.

[0031] A first slide groove 16 extending from one end to the other end is provided on the base 1, the first movable groove 14 is penetrated by the first slide groove 16, the movable part 3 is provided with a second slide groove 33, the operating assembly 4 includes an operating rod 41 capable of penetrating the first slide groove 16 and the second slide groove 33, the operating rod 41 is provided with a connecting pin 42 capable of penetrating into the movable part 3, and the connecting pin 42 is movably connected with the movable part 3. The operating rod 41 can slide forward and backward along the base 1 through the first slide groove 16, and in the process of sliding the operating rod 41 forward and backward, the connecting pin 42 is driven, and the movable part 3 is driven by the connecting pin 42 to move from the initial position to the preset position, and also from the preset position to the initial position. The second slide groove 33 is provided to facilitate the penetration of the operating rod 41 so as to facilitate the movable part 3 to be driven.

[0032] The operating rod 41 is provided with a second movable groove 411 into which the connecting pin 42 can enter and move. The connecting pin 42 can rotate in the second movable groove 411. Such a configuration enables the movable member 3 to move more smoothly.
