## Abstract

A socket wrench includes a ratcheting end including a circular opening, a crescent recess disposed on one surface, the crescent recess being adjacent to the circular opening and communicating therewith, the crescent recess having a through hole open to the other surface, and two opposite cavities at both ends of the crescent recess respectively; a cylindrical socket disposed in the circular opening; a crescent cover including two opposite projections on an outer surface, a circular hole in an intermediate portion, and two grooves adjacent to the projections respectively, the crescent cover being disposed on the crescent recess with the projections positioned in the cavities respectively; a pivotal pawl having a threaded hole, the pivotal pawl being disposed through the circular hole to align with the through hole; and a threaded fastener driven through the through hole into the threaded hole to pivotably fasten the pivotal pawl.

## Claims

### Claim 1

A socket wrench comprising:
a ratcheting end including a circular opening, a crescent recess disposed on one surface, the crescent recess being adjacent to the circular opening and communicating therewith, the crescent recess having a through hole open to an opposite surface, and two opposite cavities at both ends of the crescent recess respectively;
a cylindrical socket disposed in the circular opening;
a crescent cover including two opposite projections on an outer surface, a circular hole in an intermediate portion, and two grooves adjacent to the projections respectively, the crescent cover being disposed on the crescent recess with the projections positioned in the cavities respectively;
a pivotal pawl having a threaded hole, the pivotal pawl being disposed through the circular hole to align with the through hole; and
a threaded fastener driven through the through hole into the threaded hole to pivotably fasten the pivotal pawl;
wherein the pivotal pawl is configured to mesh with ratchet teeth of the cylindrical socket.
