Abstract
A hydraulic power tool includes a housing defining a cylinder, a piston at least partially positioned within the cylinder and movable between a retracted position and an extended position, a clevis supporting a head of the power tool, a nut coupled to an outer peripheral surface of the clevis, and a collar coupled to the housing and surrounding the nut to axially constrain the nut between the collar and the housing while permitting relative rotation between the collar and the nut.

- a clevis supporting a tool head of the power tool;
- a nut coupled to an outer peripheral surface of the clevis to permit relative rotation between the clevis and the housing;
- and
- a quick-release mechanism for removably coupling the tool head to the clevis,
- wherein the quick-release mechanism is operable to decouple the tool head from the clevis without the use of external tools.
