Abstract
There is provided in a preferred embodiment of the present invention a maintenance device having a lubricant reservoir attached to the upper end of a fixed body, and a dynamic body that is slidably engaged and disposed within the fixed body at the lower end thereof. Attached to the base of dynamic body is a trio of cleaning arms. A spring that is internally positioned between the dynamic body and the fixed body biases the dynamic body downward and the cleaning arms to a relaxed position. As the dynamic body retracts upon the application of force by a user, lubricant is released and pumped from the lubricant reservoir and each of the cleaning arms pivot and engage the side wall of the male connector.
Claims23
A maintenance device for a fastener, comprising:
- fixed body having an interior and an upper end and a lower end;
- a lubricant reservoir, said lubricant reservoir being removably attached with a threaded connection to said upper end of said fixed body;
- a dynamic body positioned within said fixed body, said dynamic body comprising a hexagonal base having six sides, a cylindrical midsection and an O-ring positioned around said cylindrical midsection;
- a first biasing spring positioned between said fixed body and said dynamic body, said first biasing spring biasing said dynamic body in a downward direction;
- and
- a plurality of cleaning arms, each pivotally connected to one said sides of hexagonal base of dynamic body;
- wherein when said dynamic body is pressed against said first biasing spring and said first biasing spring is compressed, said cleaning arms pivot to a closed position to engage said fastener.
