Abstract: A cane structure includes a handle, an electrical components set, a stick, a sleeve, a cap button, a compression spring, and a biasing post. The handle defines a receiving chamber and an inner chamber. Multiple protrusions are formed on the surrounding wall of the inner chamber. The electrical components set is removably mounted in the receiving chamber. The stick is attached to the bottom portion of the handle and conceals the inner chamber. The sleeve is fixedly disposed in the inner chamber of the handle, wherein the sleeve defines multiple through holes for being inserted with the protrusions. Also, the sleeve abuts a step in the inner chamber. The cap button and the compression spring are fitted in the sleeve. The biasing post is fitted into the sleeve and urged against the compression spring, so that the cap button can enter the receiving chamber to engage the electrical components set.

Abstract: An easily detachable stick has an umbrella installed therein. The stick includes a grip element having a root portion extending therefrom, the root portion having a platform along an axis direction and a leaf spring installed on the platform, the leaf spring having one end fixed to the platform and the other end being a free end; and a supporting pole having a hollow cavity installed therein, the cavity having an opening at one end thereof, into which the root portion is inserted, a sliding groove disposed in the opening along an axis direction of the cavity, a sliding button embedded in the sliding groove, an elastic element installed in the sliding groove between the sliding button and the opening of the cavity, and an inner flange inward protruding from the opening of the cavity, allowing the free end of the leaf spring to be supported by the inner flange.
