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. |

1. A cane structure, comprising:
a handle having a top portion and a bottom portion, wherein the top portion defines a receiving chamber extending horizontally, and the bottom portion defines an inner chamber extending vertically, wherein a plurality of protrusions are formed on the surrounding wall of the inner chamber, and the top of the inner chamber defines a central hole communicating with both the receiving chamber and the inner chamber and is formed with a step around the central hole; an electrical components set removably mounted in the receiving chamber of the handle; a stick attached to the bottom portion of the handle and concealing the inner chamber of the bottom portion of the handle; a sleeve fixedly disposed in the inner chamber of the bottom portion of the handle, wherein the sleeve defines a plurality of through holes, corresponding to the protrusions formed on the surrounding wall of the inner chamber, for being inserted with the protrusions, a top of the sleeve abuts the step formed at the top of the inner chamber, a bottom of the sleeve abuts a bottom step; a cap button fitted in the sleeve fixedly disposed in the inner chamber of the bottom portion of the handle; a compression spring fitted in the sleeve fixedly disposed in the inner chamber of the bottom portion of the handle; an upper section of a biasing post fitted into the sleeve fixedly disposed in the inner chamber and urged against the compression spring, wherein the compression spring is located between the cap button and the biasing post, so that the cap button is capable of projecting out of the central hole defined at the top of the inner chamber to enter the receiving chamber, thereby engaging the electrical components set; a clipping mechanism comprising the cap button, the compression spring, and the biasing post fixedly disposed in the inner chamber, the electrical components set removably snapped into the handle; the electrical components set comprising a circuit board, a lamp, a switch, and a warning light; the electrical components set containing a battery enclosure for accommodating at least one battery therein, the battery enclosure being provided with a plurality of holders and a plurality of conductive sheets being held in the holders, the plurality of conductive sheets comprising two front conductive sheets and one rear conductive sheets, the front conductive sheets provided with a contact and the rear conductive sheet provided with two contacts; the bottom of the electrical components set defining a recess for being engaged with the cap button, whereby the electrical components set is removably mounted in the receiving chamber of the handle, the cap button being capable of insertion into the recess, whereby the electrical components are snapped into the handle; and the sleeve integrally formed with the handle by placing the sleeve in a mold cavity for the handle, which is then introduced with molten thermoplastic material, pressure of the molten thermoplastic material forming the protrusions through the holes, and after a temperature drop the protrusions block the sleeve from moving. |
