发明名称 DRAIN PLUG REMOVER
摘要 A drain plug remover for vehicle engine oil pans includes a drain plug holding socket, a shield member and a handle. The socket, made of a resilient material, is formed having an open end which is slightly smaller than the head of the drain plug and includes longitudinal slits in its side wall, wherein, when the socket is pressed upon the drain plug, the socket expands to grasp the plug. An alternative means of holding the drain plug is by use of a magnet located within the socket. A shield member extends outwardly from the base of the socket, preferably in the form of a plate having an outer lip which curves towards the open end of the socket, thereby forming a concave, saucer-like receptacle to initially catch and subsequently deflect the flow of dirty oil away from the hand of the user. Extending from the shield member, opposing the socket, is a handle which the user grasps during removal and replacement of the drain plug. The handle includes longitudinal ridges to aid grasping and rotation of the tool. Alternatively, the drain plug remover may be formed with a second socket, in lieu of the handle, which allows removal of two different sizes of drain plugs with a single tool. The shield member preferably is formed with a concave receptacle for each socket, each concave receptacle having a lip extending toward the open end of its socket. The unused socket serves as the handle in this configuration.
