Embodiment Construction
[0019] Such as figure 1 A new type of wire-wound bobbin chuck is shown, including a disc-shaped disc body 1 made of plastic, a central hole 3 located in the center of the disc body 1 for installing the drive shaft, and a connection between the disc body 1 and the bobbin 8. The contact end surface 2 where the end surfaces are in contact, and the columnar platform 4 axially extending on the contact end surface 2 for matching with the inner circle of the bobbin 6. In the present invention, the outer surface of the columnar platform 4 is coated with metal layer 5 , the metal layer 5 forms an uneven transmission portion 51 on the outer peripheral surface of the columnar platform 4 .
[0020] In order to achieve a better use effect, in this embodiment, the transmission part 51 is evenly arranged in a zigzag shape along the outer circumferential direction of the columnar platform 4, which can generate a larger friction coefficient; and the metal layer 5 and the disc body 1 are integr...
