ABSTRACT:
A hand held tool for inserting a forward end of a cylindrical insert member into an open end of a relatively thick-walled plastic tube. The tool comprises a pistol grip having a hand engaged member that is squeezed by one's hand. A push shaft is positioned at the top end of the pistol grip, with the push shaft having a forward end that extends away from the pistol grip. The hand engaged member cooperates with a mechanism for moving the push shaft forward in longitudinal movement along the longitudinal axis of the push shaft when the hand engaged member is squeezed. A housing extends from the pistol grip around and along the push shaft, with a distal end of the housing extending beyond the forward end of the push shaft. An access opening is provided in the housing through which the forward end of the push shaft is accessible for positioning the cylindrical insert member in axial alignment with the longitudinal axis of the push shaft at the forward end of the push shaft. A gripping mechanism is provided at the distal end of the housing for gripping the open end of the plastic tube and holding the open end of the tube in axial alignment with the longitudinal axis of the push shaft. As the forward end of the push shaft moves forward, it engages the cylindrical insert member and forces the leading end of the cylindrical insert member into the open end of the plastic tube.
