Abstract
There is provided in a preferred embodiment of the present invention a maintenance device having a central body and a lubricant container attached to the upper end of the central body. At a lower end of the central body, at least one dynamic body is provided and biased by a spring to an extended position relative to the central body. The dynamic member comprises a pair of cleaning arms that are outwardly biased. As a compression force is applied to the dynamic body, the biasing spring is compressed and the dynamic body is moved toward a retracted position relative to the central body. As the dynamic body retracts, the cleaning arms pivot inward and engage the fastener for cleaning.

A maintenance device for a fastener, comprising:
- a central body having an interior and an upper end and a lower end;
- a lubricant container, said lubricant container being removably attached to said upper end of said central body;
- a first dynamic body positioned partially within said central body and forming a working head;
- a first biasing spring positioned between said central body and said first dynamic body, said first biasing spring biasing said first dynamic body in a downward direction;
- a second dynamic body positioned partially within said first dynamic body;
- a second biasing spring positioned between said first dynamic body and said second dynamic body, said second biasing spring biasing said second dynamic body in a downward direction;
- and
- a pair of cleaning arms pivotally connected to said second dynamic body;
- wherein when said second dynamic body is compressed, said cleaning arms pivot to engage said fastener.
A maintenance device for a fastener, comprising:
- a central body having an upper end and a lower end;
- a lubricant container, said lubricant container being removably attached to said upper end of said central body;
- a dynamic body connected to said lower end of said central body and configured to alternate between an extended position and a retracted position;
- a cleaning mechanism comprising a pair of cleaning arms that are in a flared position when said dynamic body is in said extended position;
- wherein when said dynamic body is moved to a retracted position, said cleaning arms pivot inward from said flared position.
