Zusammenfassung: | The present invention provides a guide device for threading steel strands, comprising: a guide head, wherein a front end of the guide head is a smooth guide end, and a hinging seat extends from a rear end; a wiring element, wherein the front end of the wiring element is correspondingly hinged on the hinging seat through a hinging plate, a rear end has a wiring hole extending along an axial direction, and the steel strand is correspondingly fixed in the wiring hole; and pull wires, which are correspondingly connected to the guide head. The guide device comprises two parts: the guide head and the wiring element which are hinged with each other; under the traction of the pull wires, the guide head can be inclined according to the direction of the hole in the bellows, so that the guide device penetrates through the bent part of the hole in the bellows more easily, thereby reducing the difficulty of threading. |
