Abstract
A caulking gun holder/driver is adapted to be driven by a cordless screwdriver or other power driver and includes two different shafts to which the driver can be attached. The holder/driver has a receptacle for receiving a tube of caulk, a threaded pusher rod with a pusher plate at its distal end to drive the caulk out of the receptacle, and flats at the proximal end to receive a power driver for 'high speed' advance or retraction of the threaded driving rod, and a main drive shaft adaptable to receive the same power driving unit to rotate the threaded rod in a 'slow speed' for better caulking application. In the dispensing mode, the threaded rod is connected via gear-reducer to the second drive shaft which permits only slow advancement of the threaded rod for better control of the flow of caulking compound out of the caulking tube, and prevention of 'dribble' when power is turned off to the driving unit.
