Patent number: 11945079Abstract: A screwdriver includes a main body and a switch. The main body is coupled to a handle and includes a pair of parallel, spaced apart slots, and a pawl positioned in each slot. Each pawl is biased outwardly by a spring. The switch is pivotable relative to the main body, and the switch includes a groove extending along an arcuate portion of an inner surface. Pivoting the switch in a first direction moves the switch toward a first position in which the groove is positioned in-line with the first pawl. When the switch is in the first position, the first pawl extends outwardly from the slot and engages the internal tooth surface such that application of a torque in a first direction drives a shank in the first direction and application of a torque in the second direction causes the shank to ratchet relative to the main body.Type: GrantFiled: March 29, 2021Date of Patent: April 2, 2024Assignee: Milwaukee Electric Tool CorporationInventors: Collin J. Nelson, Steven W. Hyma, Grant T. Squiers, James A. Cemke, Jr., Abhijeet A. Khangar
