ABSTRACT:

BACKGROUND OF THE INVENTION
1) Field of the Invention
The invention herein relates to a tool box drill bit retainer that provides for the containment of different diameter drill bits inside the tool box, the primary application of which is keeping larger size drill bits within the drill bit recess of the tool box. The improved structure of the drill bit retainer effectively enhances the orderly securing of drill bits in the tool box and increases product practicality.
2) Description of the Prior Art
In a conventional tool box drill bit holder, referring to
FIG. 1
,
FIG. 2
, and
FIG. 3
, the said conventional tool box
10
has disposed within a plurality of clips that hold a series of different diameter drill bits; larger size drill bits are grouped into a drill bit recess
11
of the conventional tool box
10
and a drill bit retainer
20
is fitted into an insertion hole
12
in the tool box
10
to keep the larger drill bits forcefully contained within the drill bit recess
11
, wherein the conventional drill bit retainer
20
consists of a fan-shaped push plate
21
extending laterally from its upper edge and a locating column
22
projecting downward vertically, with the said locating column
22
having a flat face
23
formed along one side; the insertion hole
12
of the said tool box
10
is compatible in internal shape with the outer profile of the locating column
22
and has flat face along one side; the conventional tool box
10
, as structurally described above, is capable of keeping larger size drill bits in position, but since tool boxes are frequently carried and moved about, the drill bit retainer
20
loosens in the tool box
10
insertion hole
12
, causing the larger size drill bits to become scattered among the other drill bits inside the tool box
10
, resulting in wear and damage from collisions.
In view of the said shortcomings in the structural technology of the conventional product that await improvement, the inventor of the invention herein, based on experience gained from engagement in the related industries and actual design experience, devised an original solution that culminated in the successful development of the improved tool box drill bit retainer of the invention herein.
SUMMARY OF THE INVENTION
The objective of the invention herein is to provide a tool box drill bit retainer that effectively stabilizes the containment of drill bits in the tool box and increases product practicality.
To enable a further understanding by the examination committee of the advantages, objective, and function of the invention herein as well as how the said objective is achieved, the brief description of the drawings below is followed by the detailed description of the most preferred embodiment.
