Abstract
An axis-penetrating bending-handle ratchet-wheel wrench includes an axis penetrating hole arranged on an elbow position of a bending-handle wrench rod. A ratchet-wheel head axially penetrates the axis penetrating hole. A sleeving part and a ratchet are respectively arranged on two sides of the ratchet-wheel head. Two stopping columns and a supporting column are mounted on a horizontal step surface of a penetrating step hole disposed in a drive plate according to circumferential trisection. An eccentric step hole and an elliptic arc groove are arranged on a front end of the axis penetrating hole. The ratchet, an elastic component, two ratchet blocks and the two stopping columns are built in the eccentric step hole. Three positioning concave holes are mounted near a rear end and are mounted on inner circumference of the drive plate. A concave hole set, a positioning steel ball and a spring are opposite to the positioning concave holes and are disposed on a front end of the bending-handle wrench rod. The bending-handle ratchet-wheel wrench performs clockwise transmission, anticlockwise transmission or idle running through driving of the drive plate. A relatively-long shaft body can be accommodated in the axis penetrating hole, so that the bending-handle ratchet-wheel wrench can be normally operated and used.
