The specific working process is as follows:

when the device works, the mounting shaft 5 is taken out from the first groove 16 and taken out along the mounting groove 11, the winding coil 3 is sleeved on the mounting shaft 5, because the first expansion plate 53 and the second expansion plate 55 which are arranged on the surface of the mounting shaft 5 are both arranged on inclined sides, the winding coil 3 extrudes the first expansion plate 53 and the second expansion plate 55 in the sleeving process, so that the second expansion plate 55 and the first expansion plate 53 extrude into the third groove 54 and the second groove 52, the winding coil 3 is sleeved on the mounting shaft 5 and then is installed back into the first groove 16, one end of the enameled wire is fixed on the winding coil 3, the enameled wire is controlled to pass through the upper surface of the supporting block 63, the motor is started, the motor drives the driving wheel 13 to rotate, so that the inner part of the sliding block 14 which is limited by the push rod 41 in the initial state and is meshed with the driving wheel 13 to rotate by the driven wheel 15, and the winding coil 3 rotates at a constant speed, the enameled wire is wound on the surface of the winding coil 3 which rotates at a constant speed, when the enameled wire is tangled, locked and the like, the enameled wire generates downward pressure on the supporting block 63 along with the rotation of the winding coil 3, so that the sliding rod 61 sleeved with the supporting block 63 is pressed downwards, and the sliding rod 61 slides downwards, the sliding rod 61 sliding downwards deforms the pressing bag 62, and transmits the internal gas into the expansion bladder 42 through the conduit, the expansion bladder 42 is deformed to slide the push rod 41 out of the first sliding chute 4, thereby displacing the sliding block 14, separating the driven pulley 15 from the driving pulley 13, and further the rotation of the winding coil 3 is stopped, and when the displacement restriction of the enamel wire is released, the pressure of the enamel wire to the supporting block 63 is reduced, thereby, the slide rod 61 and the slide block 14 are reset, the driven wheel 15 is meshed with the driving wheel 13 again, and the winding of the enameled wire is continued.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
