ABSTRACT:
A handle set includes two telescopic handles with freely adjustable length. Each of the telescopic handles includes a first tube, a second tube into which the first tube is telescopically insertable, a tubular anchor with an upper tip attached to a lower tip of the first tube, a lower portion defining a plurality of slits so that the lower portion of the tubular anchor can be expanded easily, a link insertable through the first tube, a plug attached to a lower tip of the link. The plug can be moved to an upper position by pulling the link for abutting the lower portion of the tubular anchor against the first tube for restraining the first tube relative to the second tube. The plug can be moved to a lower position by pushing the link for releasing the lower portion of the tubular anchor from the first tube for allowing the movement of the first tube in respect to the second tube. Each of two link-driving devices is connected between a grip and one of the telescopic handles. The links can be driven by means of the link-driving devices by pivoting the grip.
