[0038] It should be noted that the active roller 3 is driven by electricity and rotates under the drive of an external power source to drive the coil to move.

[0039] In the above embodiment, the bearing driving part includes a plurality of driven rollers 6, which are evenly arranged on the bottom wall of the inner cavity of the device body 1 and extend from the feed port to the discharge port.
