Abstract
An apparatus for dispensing plastic fasteners from fastener stock includes a gun shaped casing. A hollow needle having an inlet opening is mounted on the casing. A guide groove is formed on the casing for receiving the fastener stock, the guide groove being in communication with said inlet opening in said hollow needle. A feeder element for intermittently advancing fastener stock loaded into the guide groove is mounted on the casing. An ejector rod is provided for pushing plastic fasteners from the fastener stock through and out of the hollow needle one at a time. The ejector rod and feeder element are driven by a DC motor powered by a battery pack removably mounted in the casing and which contains rechargeable batteries. The battery pack includes a receptacle which is arranged to enable the batteries to be recharged with the battery pack in or out of the tool. A converter assembly is provided for converting rotary motion of the drive shaft of the motor into linear motion of the ejector rod, the converter assembly including a worm on the drive shaft, a worm gear driven by the worm, a spur gear loosely coupled to the worm gear, a slider for holding the ejector rod and a rack driven …
