Claim:
A display bracket for a wrench, comprising: a main body being a planar slab having a front side, a rear side and a locking hole going through said main body at a predetermined location thereon, said locking hole further including a pair of symmetric, parallel slots of predetermined depth in a horizontal direction straddling said locking hole on said main body, a flexible piece being formed between said symmetric slots and including a pointed portion formed on the top thereof; and a mount capable of being connected to said locking hole, said mount consisting of an engaging portion with a polygonal circumference and a cylindrical connecting member, whereby said connecting member will be inserted in said locking hole by the engagement between a plurality of arced projections therearound and one of said front side and said rear side of said main body, said connecting member being further secured on said locking hole by the engagement between a ratchet therearound and said flexible piece; wherein said symmetric slots on two sides of said flexible pieces have a length substantially equal to the thickness between the front side and said rear side and a notch is cut on a side of a flange on the rear side of said main body, said flexible piece becoming an isolated body on said flange for jumping when it is urged; wherein said ratchet being composed of a multitude of continuous oblique teeth surrounding said ratchet so that when said connecting member is inserted into said locking hole, said pointed portion of said flexible piece can be engaged with said ratchet, thereby said flexible piece will go through a transverse jump across said symmetric slots and will produce a sound by the jump of said pointed portion against said ratchet.
