Torque adapter with ratchet reverse feature

摘要

A torque transmittal tool has an input socket to receive a drive input from a drive tool. The input socket causes a first link to rotate through a range of rotation upon rotation of the input socket. The first link is fixed to rotate with an extension link. The extension link is fixed to rotate with an output link. The output link includes an output ratchet for transmitting rotation, and has a torque reversal button which may be actuated to change the direction of rotation of the output ratchet. An actuator has an unactuated position where a contact surface is spaced away from the torque reversal button, and an actuated position at which it actuates the torque reversal button. A method is also disclosed.

1. A torque transmittal tool comprising:
an input socket to receive a drive input from a drive tool, and said input socket causing a first link to rotate through a range of rotation upon rotation of said input socket, said first link being fixed to rotate with an extension link, and said extension link being fixed to rotate with an output link, said output link including an output ratchet for transmitting rotation, and said output ratchet having a torque reversal button which may be actuated to change a direction of rotation of said output ratchet; an actuator for said output link, said actuator having an unactuated position where a contact surface is spaced away from said torque reversal button, and having an actuated position at which said contact surface actuates said torque reversal button; and said actuator is a fork having arms extending along a side of said output link, with said output link being biased outwardly relative to a channel in said fork, and said fork being moveable relative to said output link such that one of said arms is said contact surface for actuating said torque reversal button.
