Abstract
Abstract A handle device includes two tubes slidably engaged in two pipes which has a number of teeth. A handle is secured on top of the tubes and has a hand grip slidably engaged in the lower portion. Two blocks are secured to the lower ends of the tubes. Two catches are slidably engaged in the blocks. Two bars are slidably engaged in the catches and the blocks and coupled to the hand grip. The catches are forced to engage with the teeth when the hand grip is not pulled and are disengaged from the teeth so as to release tubes from the pipes when the hand grip is released.
