发明名称 Winch handle
摘要 A winch handle for a winch has an extendable arm with an extended position and a retracted position. The retracted position of said extendable arm being equal to or within the diameter of the winch. In its retracted position, the extendable arm is shaped in a fashion that does not interfere with the operation of the winch while the handle is not needed. The extended position of the extendable arm is longer than the diameter of the standard winch and is useful for turning the winch. The winch handle may also have a grip.
