Abstract
A tubular tool includes a tubular first part and a tubular second part. The tubular first part including a first section having an engaging hole defined in the distal end thereof, and a second section having a connection hole defined in the distal end thereof so as to be respectively connected to a driving tool and an object. The tubular second part is rotatably mounted to the first outer periphery of the first section of the first part. At least one lip extending from the inner periphery of the tubular second part. At least one first circular rib extends outward from the first outer periphery of the first section. The at least one lip is engaged with the at least one first circular rib to restrict the second part from separating from the first prat.
Claims12
A tubular tool comprising:
- a tubular first part including a first section and a second section which is located opposite to the first section, the first section having an engaging hole defined in a distal end thereof, the second section having a connection hole defined in a distal end thereof;
- the connection hole being adapted to be connected with a driving tool, the engaging hole being adapted to be connected with an object, the driving tool rotating the object through the tubular first part of the tubular tool;
- two first circular ribs, at least one second circular rib and at least one third circular rib respectively extending outward from a first outer periphery of the first section and located corresponding to the engaging hole, the at least one second circular rib being located between the two first circular ribs and the at least one third circular rib;
- a top width of each of the two first circular ribs being larger than at least two times of a distance between the two first circular ribs;
- an outer diameter of the first section being smaller than that of the second section, and
- a tubular second part having a mounting hole defined axially therethrough, two lips extending inward from an inner periphery of the tubular second part, the tubular second part rotatably mounted to the first outer periphery of the first section of the first part, the two lips engaged with the two first circular ribs correspondingly to restrict the second part from separating from the first part, and outer peripheries of the two first circular ribs, the at least one second circular rib and the at least one third circular rib are respectively in contact with an inner periphery of the mounting hole.
