Examples

Referring to fig. 1 to 3, an anti-rolling jig 200 provided in this embodiment includes a hoop 201 and a clamp ring 202 sleeved in the hoop 201, that is, an inner-outer embedding manner is adopted between the hoop 201 and the clamp ring 202. The inner hole 205 of the snap ring 202 may be used to be sleeved on the shaft body of the coil tube core, that is, the tube core 101 of the mother coil 100, usually one end of the coil will be connected with a cylindrical shaft body, that is, the tube core 101, and wound around the axial direction of the tube core 101 one turn, so as to form the mother coil 100 finally, while the wound coil length is too large, which usually results in the diameter of the mother coil 100 being too large, once the two ends of the tube core 101 do not limit and support the two ends of the mother coil 100, the axial unwinding phenomenon will occur in the unreeling process of the mother coil 100. Therefore, the jig 200 is configured at one end or two ends of the parent coil 100 which are easy to unwind, so that the phenomenon of unwinding of the parent coil 100 can be effectively prevented, and only the connection stability between the whole jig 200 and the tube core 101 and the stability of supporting the end face of the parent coil 100 are required to be ensured.
