摘要： A telescoping handle device may include an outer housing which may be slidably coupled to a shaft. The outer housing may have an elongated side wall, and the side wall may terminate in a first end and a second end. A cavity may be formed within the side wall, and the cavity may include a key channel and a lock groove. The shaft may be movable within the cavity, and the shaft may have an upper end and a lower end. A shaft key may be coupled to the shaft, and the shaft key may be slidably engaged within the key channel so that the shaft key is slidable between the first end and the second end. The shaft key may be rotatable out of the key channel and into the lock groove to prevent the shaft key from being slidable between the first end and the second end.
