The wire 01 stands up with its surface clamped after passing through the wire clamping passage. Because the guide pulley 10 of the eccentric shaft 8 can be automatically adjusted according to the guide specification, the wire standing device can adapt to the guide of various specifications, and the universality of the wire standing device is improved.
In addition, in order to limit the wire from sliding out from the width or thickness direction, the wire is ensured to be clamped stably in the clamping channel, the adjacent guide devices of the clamping devices clamped from the width direction clamp from the thickness direction, and the adjacent guide devices of the clamping devices clamped from the thickness direction clamp from the width direction.
