Patent attributes
A power ratchet includes a ratchet body and a handle portion connected to the ratchet body. A ratchet assembly is disposed within a cavity of the ratchet body. The ratchet assembly includes a drive member, a pawl, and a ring gear. The ring gear is rotatable within the cavity and includes inner teeth that interface with the pawl. The ring gear has a flange with an interfacing surface and a cam follower. A drive assembly of the power ratchet has a motor and a drive shaft. The drive shaft includes a cam. The cam interfaces with the cam follower when the motor unit rotates the drive shaft to rotate the drive member via the pawl and the inner teeth. The interfacing surface of the flange interfaces with a stop surface formed in the cavity to transfer a torque applied to the handle portion to the drive member.
