发明名称 EXTENSION POLE MECHANISM FOR PAINT ROLLER
摘要 An extendable pole mechanism may be used with a pair of poles that are longitudinally movable to adjust the overall length of both poles. The mechanism may include a housing that receives the poles and a trigger that is moveable with respect to the housing to adjust the mechanism between a use condition, where the poles are held in a longitudinally relative fixed position, and an adjustment condition, where the poles are longitudinally moveable with respect to each other.
