Abstract

Disclosed is a foldable wrench capable of containing various tool bits. The wrench consists of a fixed handle having a first compartment for accommodating rod-shaped tool bits, a first removable cover for covering the first compartment, a movable handle having a second compartment for accommodating socket-shaped tool bits, a second removable cover for covering the second compartment, and a riveting pin pivotally connecting the first removable cover, the fixed handle, the movable handle, and the second removable cover, through holes formed on overlapping portions separately provided on the four components so that each of such components can be pivotally turned about the riveting pin relative to one another. By this way, tool bits contained in the first and the second compartments can be easily retrieved or stored by conveniently turning the first and the second removable covers away from the fixed and the movable handles, respectively; and, the fixed and the movable handles may be turned toward each other from a perpendicular relation to a parallel relation to occupy the smallest possible room for convenient carrying and storage.

Claims

1. A foldable wrench capable of containing various tool bits therein, comprising a fixed handle, a first removable cover, a movable handle, a second removable cover, and a riveting pin;

said fixed handle being provided with a front tool bit receiving head for removably receiving a tool bit to be used for a certain operation, a first compartment for containing rod-shaped tool bits therein, a wave-profiled grip portion suitable for gripping by fingers, a first overlapping portion opposite to said tool bit receiving head, and a first through hole centered on said first overlapping portion;

said first removable cover having a configuration corresponding to that of said fixed handle for fitly superimposing on said fixed handle and covering said first compartment, and a second through hole corresponding to said first through hole;

said movable handle being provided with a second compartment formed with a plurality pairs of clamping members for containing socket-shaped tool bits therein, a wave-profiled grip portion corresponding to said grip portion of said fixed handle, a second overlapping portion corresponding to said first overlapping portion of said fixed handle, and a third through hole centered on said second overlapping portion corresponding to said second through hole;

said second removable cover having a configuration corresponding to that of said movable handle for fitly superimposing on said movable handle and covering said second compartment, and a fourth through hole corresponding to said third through hole; and

said riveting pin pivotally connecting said first removable cover, said fixed handle, said movable handle, and said second removable cover sequentially by extending through said second, said first, said third, and said fourth through holes and being securely retained in said through holes by means of a top cap and a bottom cap fitly plugged into said first and said fourth through holes, respectively, such that said first removable cover, said fixed handle, said movable handle, and said second removable cover may be turned about said riveting pin relative to one another, that said first and said second removable covers may respectively open or close said first and said second compartments easily to facilitate the retrieval or the storage of tool bits from or in said compartments, and that said fixed handle and said movable handle may be turned toward each other from a perpendicular relation to a parallel relation to occupy the smallest possible room for convenient carrying.
