ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to a litter picker, and more particularly to a manually-operated litter picker.
2. Description of Related Art
The conventional litter picker comprises two elastic clamps for picking up bits or scraps of rubbish scattered about on the ground; it is a handy tool to get rid of the litter on the ground. However, the conventional litter picker is prone to put a strain on the hand of a user.
BRIEF SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a manually-operated litter picker which is easy to use, without being burdensome to its user.
In keeping with the principle of the present invention, the foregoing objective of the present invention is attained by the litter picker comprising a pistol grip, an extension rod, a fixed tube, a movable tube, two claws, two link members, and a pull cord. The movable tube is actuated by the pull cord to slide in the direction toward the fixed tube, thereby causing the two claws to swivel toward each other to bring about the holding action by which the litter is picked up.
The features and the advantages of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of the present invention with reference to the accompanying drawings.
