ABSTRACT:
A support mechanism for a rotatable conductor wrapping bit for quick detachment from a conductor wrapping tool includes a housing for the bit and for a rotatable bit driver member. Radially inwardly projecting pins are disposed on the housng and project into a bore which receives a sleeve on the motor housing having opposed "j" slots. One of the pins is radially inwardly movable into locking engagement with the bit driver member whereby, upon detachment of the support mechanism from the motor casing, the bit driver member and the bit are locked in a predetermined indexed or rotationally oriented position relative to the housing. The bit driver member includes a spring disposed in a bore formed therein and engageable with a coupling part for permitting axial excursion of the bit to accommodate the axial space occupied by successive helical convolutions of conductor wire as a coiled connection is formed.
