The guidance device which comprises a driving guide axle, a driven guide axle, and a transmission installation and the winding drum are disposed in the case. The driving and driven guide axles each provides a helical groove spiralling in opposite direction for the guidance of the wire passing through to spirally lap over the winding drum during recoiling. In which, the spring back force of the winding drum during reverse rotation will be transmitted to drive the driving and driven guide axles to rotate in opposite direction by the transmission installation.
