Abstract

A multifunctional pick-up tool comprises: a central shaft disposed in a tubular body; a battery chamber jointed with the tubular body for storing a battery pack; at least a bulb located at the bottom end of the tubular body; a bundle of conductive cords arranged between the bulb and the battery chamber; a multiheaded claw and a resilient member disposed at a lower and an upper end of the central shaft respectively; an upper and a lower end of the resilient member propped against a push button on the central shaft and a pull knob on the tubular body; and a magnet positioned at the bottom end of the tubular body.

Claims

1. A multifunctional pick-up tool, comprising:

a tubular body jointed with a battery chamber and a switch, wherein at least a bulb is located at a bottom end of the tubular body;

a bundle of conductive cords is arranged between the bulb and the battery chamber and controlled by the switch to or not to lighten the bulb; and

a pull knob is resided at an upper end of the tubular body; and

a central shaft penetratingly plugged in the tubular body, wherein an upper end of the central shaft protrudes over the upper end of the tubular body;

a multiheaded claw is disposed at a bottom end of the central shaft;

an outer diameter encircled by a plurality of fully extended claws of the multiheaded claw is greater than the bore of the tubular body;

a resilient member is hitched on the upper end of the central shaft; and

a button is attached to the upper end of the central shaft so that two ends of the resilient member are propping against a bottom end of the button and a top end of the pull knob respectively;

wherein the claws of the multiheaded claw can fully spread outwardly when the pull knob is pulled to have the claws emerged from the tubular body, or the claws will be closed and retracted in the tubular body when the pull knob is released.

2. The multifunctional pick-up tool according to claim 1, wherein a flexible bar is disposed at the bottom end of the central shaft, and the plurality of claws is secured to the bottom end of the flexible bar.

3. The multifunctional pick-up tool according to claim 1, wherein the switch is disposed at the bottom end of the battery chamber.

4. The multifunctional pick-up tool according to claim 1, wherein a magnet is disposed
