Adjustable Socket Wrench

摘要

An adjustable wrench provides a drive head that rotates about two axis with respect to a drive gear. The wrench includes a wrench casing having an orbital cavity. A drive head, drive gear, pawl gear and an axis pin bushing are positioned in the orbital cavity. A drive head axis pin connects the drive head to the axis pin bushing such that the drive head can rotate about a first axis with respect to the drive gear. A drive gear axis pin connects the drive gear to the axis pin bushing such that the drive head can rotate about at second axis with respect to the drive gear. The pawl gear and drive gear rotate the drive head about a third axis with respect to the wrench casing.
