An extensible anchoring apparatus for a multi-section pulling bar of a trunk has an anchoring means located in a pulling bar means to allow the pulling bar positioned securely at the retracted condition. The pulling bar means includes a handle having two ends each has a bottom side fastened to an inner tube with a linkage bar located therein. The inner tube is housed in a middle tube and the middle tube is housed in an outer tube. The tubes have respectively latch bores formed on the tubular walls. The outer tube further has an anchor bore located at the bottom section. The anchoring apparatus comprises an upper anchoring means located at a lower end of the inner tube and a lower anchoring means located at a lower end of the middle tube. The lower anchoring means has a lower engaging seat which has a coupling bore and an aperture formed on the side walls for housing a lower extensible button. When the bottom end of the upper anchoring means is located above the top end of the lower anchoring means, the jutting stub of the lower extensible button of the lower anchoring means may be urged to retract and the anchor bolt may be extended to engage with the anchor bore of the outer tube thereby to keep the pulling bar at a steady and secured condition.
