Abstract
The invention relates to a securing means for the telescopic stick of a multiple-fold umbrella, mainly comprising a U-shaped resilient element having round holes disposed thereon mounting on a stub with the two end portions extending into the grooves situated on the sides of the stub. On the stub is transversely arranged a hole that provides rooms for a spring and a locating plunger. The stub, integrated with the spring and the plunger, is placed into an inner tube where the stub, in conjunction with detent balls and positioning holes on the peripheral walls of the inner and the outer tubes, can provide stable, reliable latching and positioning functions for telescopic tubes as the umbrella is opened.
