ABSTRACT:
A device is provided for clearing iron chips produced during a mechanical working process and includes a plurality of telescopic housings. A fastening member is securely attached to the underside of an upper plate of the telescopic housing. A recess having a substantially T-shaped cross-section is defined in an underside of the fastening member. A groove having an arc-shaped cross-section is defined in the underside of a first side wall member of the fastening member. A first flange portion is laterally formed on a second side wall member of the fastening member and extends outwardly therefrom. A resilient member is securely attached to the fastening member and includes a locking element having a substantially Y-shaped cross-section securely received in the substantially T-shaped recess. A lug portion having an arc-shaped cross-section is formed on a first side of the resilient member and is partially enclosed in the arc-shaped groove. A clearing edge portion extends from a distal end of the arc-shaped lug portion for clearing iron chips produced during a mechanical working process. A second flange portion having an L-shaped cross-section is formed on a second side of the resilient member and is securely mounted on the first flange portion.
