Toolbox

Abstract

A toolbox, which includes a box body, a number of tool bit holders pivotally mounted inside the box body and linked to one another by links, and a top cover pivoted to the box body with two flat pivot bolts for forcing the tool bit holders from a horizontal position to a tilted position when it is opened from the box body.

1 . A toolbox comprising: 
 a box body, said box body comprising two coupling holes aligned at two opposite lateral sides thereof near one end, and engagement teeth bilaterally formed in each of the two coupling holes of said box body;    a top cover, said top cover comprising two mounting lugs respectively downwardly extending from two opposite lateral sidewalls thereof near one end, said mounting lugs each having an elongated coupling hole and a side notch;    a first tool bit holder, said first tool bit holder comprising two opposite sidewalls, two dual sector-like coupling holes symmetrically disposed at the two opposite sidewalls, and two side pins respectively perpendicularly extending from the two opposite sidewalls corresponding to the side notches of the mounting lugs of said top cover;    a plurality of second tool bit holders respectively pivotally mounted inside said box body;    a plurality of links respectively coupled to said first tool bit holder and said second tool bit holders; and    two flat pivot bolts respectively mounted in the coupling holes of the mounting lugs of said top cover, the coupling holes of said box body and the dual sector-like coupling holes of said first tool bit holder to pivotally secure said top cover and said first tool bit holder to said box body, said flat pivot bolts each having engagement teeth symmetrically disposed at two opposite sides.    Wherein when opening said top cover from said box body, the side notches of the mounting lugs of said top cover are forced into engagement with the side pins of said first tool bit holder to further force said first tool bit holder to a tilted position relative to said box body, and at the same time said links are forced to turn said second tool bit holders to a tilted position and said flat pivot bolts are turned with said top cover to force the engagement teeth thereof into engagement with the engagement teeth in the coupling holes of said box body to stop said first and second tool bit holders in the tilted position.
