Abstract
A power tool includes a tool body having a user input and a controller to control operation in response to a first signal from the user input, a yoke coupled to the tool body with a first leg defining a first aperture and a second leg defining a second aperture, and a clevis. The clevis includes a pin insertable into the apertures and rotatable relative to the yoke to transition between locked and unlocked configurations to removably couple a jaw assembly to the yoke, and a lever at a second end of the pin positioned external to the yoke. A sensor is coupled to the tool body, yoke, or housing to sense the clevis configuration, sending a second signal to the controller to provide an indication to a user.
Claims20
A power tool comprising:
- a tool body including a user input and a controller to control operation of the power tool based in response to a first signal from the user input;
- a yoke coupled to the tool body and including a first leg defining a first aperture and a second leg defining a second aperture;
- a clevis including:
- a pin that is insertable into the first aperture and the second aperture and rotatable relative to the yoke to transition the clevis between a locked configuration and an unlocked configuration to removably couple a jaw assembly to the yoke, and
- a lever at a second end of the pin that is positioned external to the yoke;
- and
- a sensor coupled to at least one of the tool body, the yoke, or a housing of the power tool to sense when the clevis is in one of the locked configuration or the unlocked configuration, the sensor sending a second signal to the controller so that the controller provides an indication to a user corresponding to the configuration of the clevis.
A clevis for removably coupling a working head to a power tool, the clevis comprising:
- a pin having a first end and a second end opposite the first end, the pin defining a circumferential channel extending around an outer surface of the pin at the second end and a notch formed within the channel, the notch extending radially inward from the channel;
- a lever coupled to the second end of the pin and configured to rotate the pin between a locked configuration and an unlocked configuration, the lever defining a recess;
- and
- a lock including a locking member retained in the recess, the locking member extending out of the recess to provide frictional engagement in the locked configuration.
A power tool comprising:
- a housing;
- a yoke rotatably coupled to the housing, the yoke having a first leg with a first aperture and a second leg with a second aperture;
- a clevis pin extending through the first aperture and the second aperture, the clevis pin rotatable between a locked configuration securing a working head to the yoke and an unlocked configuration permitting removal of the working head;
- a lever coupled to the clevis pin and positioned external to the second leg, the lever movable to rotate the clevis pin between the locked configuration and the unlocked configuration;
- a sensor that detects a position of the lever;
- and
- a controller that disables operation of the power tool when the sensor detects the clevis pin is in the unlocked configuration.
