Abstract
A joint recognition member is revealed. The joint recognition member includes a joint body formed by a cylinder connected with a polygonal prism. A polygonal hole with a magnet part is set on the cylinder so as to attract driver bits by magnetic force. The device features on that: a narrow neck part with a ring groove is arranged at one end of the cylinder near the polygonal prism. The ring is wrapped around the narrow neck part and outside diameter of the ring is no smaller than that of the cylinder. A protruding ring on the ring is mounted and moved freely in the ring groove. An outer surface of the ring is labeled with words such as size. According to the corresponding polygonal hole, the ring has different shapes and sizes in various colors for fast recognition.
Claims20
A joint recognition member, comprising:
- a joint body, which has a one piece structure, having a cylinder formed at one end and a polygonal prism integrally formed at an opposed end, wherein said cylinder has a polygonal hole formed at an opening end thereof and a narrow neck part integrally formed at a position between said opening end of said cylinder and said polygonal prism, wherein a ring groove is formed at said narrow neck part of said joint body;
- and
- a ring rotatably wrapped around said narrow neck part of said joint body, wherein said ring is stationary when said joint body is rotated, wherein said ring has a protruding ring formed at an inner surface and engaged with said ring groove to enable said ring to be freely rotated at said narrow neck part which is formed at said cylinder of said joint body and prevent any longitudinal movement along said narrow neck part of said joint body, wherein a tapered inner surface of said ring abuts against a tapered axially facing outer edge on top of said narrow neck part, wherein an axially facing bottom surfaced of said ring is abutted at an axially facing top surface of said cylinder, wherein said protruding ring has a curved surface formed at an inner wall thereof that is tapered from bottom to top and a barb part formed on top of said curved surface of said protruding ring such that when said protruding ring is engaged with said ring groove, said curved surface of said protruding ring enables said protruding ring to mount in said ring groove while said barb part of said protruding ring is leaned against a top surface of said ring groove so as to prevent said protruding ring to be removed from said narrow neck part of said joint body in a direction towards said polygonal prism, wherein said ring is prohibited to move to said cylinder from said polygonal prism due to the abutment of said bottom surface with said top surface of said cylinder.
A joint recognition member, comprising:
- a joint body, which has a one piece structure, having a cylinder formed at one end and a polygonal prism integrally formed at an opposed end, wherein said cylinder has a rectangular prism with a bead formed at a free end thereof and a narrow neck part integrally formed at a position between said cylinder and said rectangular prism, wherein a ring groove is formed at said narrow neck part of said joint body
- a ring rotatably wrapped around said narrow neck part of said joint body, wherein said ring is stationary when said joint body is rotated, wherein said ring has a protruding ring formed on an inner surface and engaged with said ring groove to enable said ring to be freely rotated at said narrow neck part which is formed at said cylinder of said joint body and prevent any longitudinal movement along said narrow neck part of said joint body, wherein a tapered inner surface of said ring abuts against a tapered axially facing outer edge on top of said narrow neck part, wherein an axially facing bottom surfaced of said ring is abutted at an axially facing top surface of said cylinder, wherein said protruding ring has a curved surface formed at an inner wall thereof that is tapered from bottom to top and a barb part formed on top of said curved surface such that when said protruding ring is engaged with said ring groove, said curved surface of said protruding ring enables said protruding ring to mount in said ring groove while said barb part of said protruding ring is leaned against a top surface of said ring groove so as to prevent said protruding ring to be removed form said narrow neck part of said joint body in a direction towards said rectangular prism, wherein when said ring is mounted at said ring groove, said ring is prohibited to move in an opposite direction from said cylinder to said rectangular prism.
