ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates generally to pick-up tools, more particularly to a multifunctional pick-up tool equipped with a multiheaded claw, a magnet, and a bulb for picking up small things easily in a limited space.
2. Description of the Prior Art
During maintaining or repairing a car or a motorcycle, it is nothing peculiar to have some small parts or tools, such as screws, washers, rivets, or a spanner, dropped from a technician's palm down to somewhere in a complicated machine chamber. For picking up the dropped things, sometimes the technician may have to make a great effort by holding a flash-light with one hand and a long clamp with the other to exhaust himself just because of a trivial screw.
It seems that not much one can do but wait helplessly on the spot when a key is dropped down into a sidewalk ditch, he cannot even have a chance to make sure if the key is still lying there in the dark ditch. Under this situation, all he needs is a pick-up tool with bulb.
SUMMARY OF THE INVENTION
The primary object of this invention is to provide a multifunctional pick-up tool with a stretchable, spreadable, and closable multiheaded claw disposed in a long tubular body for picking small things up easily in any limited space.
Another object of this invention is to provide a multifunctional pick-up tool equipped with a magnet disposed at a lower end of the pick up tool just by the side of the multiheaded claw, so as to pick up some small metal mechanical parts dropped down in a dim place.
Yet another object of this invention is to provide a multifunctional pick-up tool equipped with a bulb as a light source when seeking to pick up small things in the dark.
In order to realize above said objects, a multifunctional pick-up tool of this invention comprises: a central shaft disposed in a tubular body; a battery chamber jointed with the tubular body for storing batteries; 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 shalt respectively; an upper and a lower end of the resilient member propped against a 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 for collecting small metal things or parts. The user may push the knob until the multiheaded claw is fully spread outwardly, then release the push knob of the multiheaded claw to shrink back and grasp the target things or adsorb ferromagnetic parts with the magnet in both ways.
For more detailed information regarding this invention together with further advantages or features thereof, at least an example of preferred embodiment will be elucidated below with reference to the annexed drawings.
