Drill force indicator for hand-operated drills

摘要

An apparatus for indicating a drilling thrust of a hand-operated drill includes a thrust-indicator assembly for attaching between a drill motor and a drill chuck of the hand-operated drill to indicate the drilling thrust. A method of indicating a drilling thrust asserted on a hand-operated drill includes: attaching a thrust-indicator assembly between a drill motor and a drill chuck of a hand-operated drill; and indicating, with the thrust-indicator assembly, a drilling thrust asserted on the drill chuck.

主权项

1. An apparatus which indicates a drilling thrust of a hand-operated drill comprising:
a thrust-indicator assembly configured to attach between a drill motor and a drill chuck of a hand-operated drill to indicate a drilling thrust, the thrust-indicator assembly comprising: a driven member, a driver member, a driven mating member, and a driver mating member; wherein when the drill motor is rotating and a drilling thrust is under a thrust threshold the driver mating member is configured to extend through a hole in the driver member and through a slot in the driven member and the driven mating member is configured to remain mated with the driver mating member so that the driven member rotates with the driver member so that the driven member rotates the drill chuck; wherein when the drill motor is rotating and the drilling thrust is over the thrust threshold the driven mating member is configured to un-mate from the driver mating member so that the driven member stops rotating thereby stopping rotation of the drill chuck while the driver member continues to rotate with the drill motor.
