Abstract
An adaptor device includes an adaptor and a retainer. The adaptor includes a first end removably mounted in a box end of a wrench and a second end releasably engaged with an object such as a tool bit. The retainer is fixed to the first end of the adaptor and includes at least two resilient retaining sections on an outer periphery thereof. A slit is defined between two resilient retaining sections that are adjacent to each other. The resilient retaining sections abut against an edge of the box end of the wrench, thereby providing an engaging force between the resilient retaining sections and the edge of the box end that is greater than an engaging force between the adaptor and the tool bit. Thus, the tool bit can be disengaged from the adaptor without causing disengagement of the adaptor from the box end of the wrench.
Claims16
An adaptor device adapted to be removably mounted in a box end of a wrench, the adaptor device comprising:
- an adaptor including a first end adapted to pass into and be removably mounted in the box end of a wrench, with the adaptor including a second end located outside of the box end of the wrench when the first end is mounted in the box end and having a configuration adapted to be releasably engaged with an object;
- and
- a retainer fixed to the first said of the adaptor, the retainer including at least two resilient retaining sections on an outer periphery thereof, a slit being defined between said at least two resilient retaining sections, said at least two resilient retaining sections having a compressed size adapted to pass through the box end of the wrench and having an uncompressed shape larger than the box end of the wrench and adapted to abut against an edge of the box end of the wrench, thereby providing an engaging force between said at least two resilient retaining sections and the edge of the box end that is greater than an engaging force between the second end of the adaptor and the object.
An adaptor device adapted to be removably mounted in a box end of a wrench, the adaptor device comprising:
- an adaptor including a first end adapted to pass into and be removably mounted in the box end of the wrench, with the adaptor including a second end located outside of the box end of the wrench when the first end is mounted in the box end and having a configuration adapted to be releasably engaged with an object;
- and
- a retainer fixed to the first end of the adaptor, the retainer including a plurality of radially extending resilient retaining sections on an outer periphery thereof, a slit being defined between two of said resilient retaining sections that are adjacent to each other, said resilient retaining sections having a compressed size adapted to pass through the box end of the wrench and having an uncompressed shape larger than the box end of the wrench and adapted to abut against an edge of the box end of the wrench, thereby providing an engaging force between the resilient retaining sections and the edge of the box end that is greater than an engaging force between the second end of the adaptor and the object.
A device comprising:
- a wrench having a box end;
- an adaptor including a first end removably received and mounted in the box end of the wrench in a nonrotatable manner, with the adaptor including a second end located outside of the box end of the wrench when the first end is mounted in the box end and having a configuration adapted to be releasably engaged with an object;
- and
- a retainer fixed to the first end of the adaptor, the retainer including at least two resilient retaining sections on an outer periphery thereof, a slit being defined between said at least two resilient retaining sections, said at least two resilient retaining sections having a compressed size passable through the box end of the wrench in a mounting direction and having an uncompressed size larger than the box end of the wrench and abuttable against an edge of the box end of the wrench, thereby providing an engaging force between the resilient retaining sections and the edge of the box end when a force applied opposite to the mounting direction that is greater than an engaging force between flap second end of the adaptor and the object applied for releasing the object from the adaptor opposite to the mounting direction.
