Bit retainer
Abstract
A bit retainer includes a body including a series of passages
extending therethrough and a partition formed between every two
adjacent passages. Each passage has an upper end laterally
extending to a front side of the body to define a first opening and
a lower end laterally extending to a backside of the body to define
a second opening. The first opening has an enlarged portion defined
in a lower portion of the first opening and the second opening has
an enlarged portion defined in a top portion of the second opening.
The enlarged portion of the first opening and the enlarged portion
of the second opening linearly correspond to each other.

Claims
What is claimed is:
1. A bit retainer comprising a body including a series of passages
extending through the body for received bits and a partition formed
between every two adjacent passages for clamping bits, each passage
having an upper end laterally extending to a front side of the body
to define a first opening and a lower end laterally extending to a
backside of the body to define a second opening, the first opening
having an enlarged portion defined in a lower portion of the first
opening and the second opening having an enlarged portion defined
in a top portion of the second opening, the enlarged portions of
the first opening and the enlarged portion of the second opening
linearly correspond to each other and each having a diameter
slightly greater than that of the bit for user to easily detach the
bit from the body.
Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a retainer, and more
particularly to a bit retainer.
[0003] 2. Description of Related Art
[0004] A conventional bit retainer in accordance with the prior art
shown in FIGS. 4-6 comprises body (30) including an L-shaped
cross-section and a series of passages (31) defined therein. The
series of passages (31) are parallel relative to one another so
that a partition (32) is formed between every two adjacent passages
(31). Each passage (31) has a vertical portion (311) extending
through the body (30) and an enlarged portion (312) obliquely
extending to a bottom of the body (30).
[0005] To operate the conventional bit retainer, the bit is
longitudinally received in a corresponding one of the series of
passages (31) and clamped between the two adjacent partitions (32)
for ordering the bits. The bit is wrench toward the front side of
the body (30) and received in the enlarged portion (312) of the
passage (31). The enlarged portion (312) has a diameter slightly
greater that that of the bit so that the user can easily detach the
bit from the body (30).
[0006] For receiving the oblique bit, the bottom of the body (30)
extends to contain the enlarged portion (312) of the passage (31)
so that the width (W1) of the body (30) is widened. Consequently,
the volume of the conventional bit retainer is enlarged. As a
result, the conventional bit retainer takes more material during
inject molding and more transport cost.
[0007] The present invention has arisen to mitigate and/or obviate
the disadvantages of the conventional bit retainer.
SUMMARY OF THE INVENTION
[0008] The main objective of the present invention is to provide an
improved bit retainer that has a small volume.
[0009] To achieve the objective, bit retainer in accordance with
the present invention comprises a body including a series of
passages extending therethrough and a partition formed between
every two adjacent passages. Each passage has an upper end
laterally extending to a front side of the body to define a first
opening and a lower end laterally extending to a backside of the
body to define a second opening. The first opening has an enlarged
portion defined in a lower portion of the first opening and the
second opening has an enlarged portion defined in a top portion of
the second opening. The enlarged portion of the first opening and
the enlarged portion of the second opening linearly correspond to
each other.
[0010] Further benefits and advantages of the present invention
will become apparent after a careful reading of the detailed
description with appropriate reference to the accompanying
drawings.

FIG. 5 along line 6-6.
DETAILED DESCRIPTION OF THE INVENTION
[0017] Referring to the drawings and initially to FIGS. 1-3, a bit
retainer in accordance with the present invention comprises a body
(10) including a series of passages (11) extending therethrough and
a partition (12) formed between every two adjacent passages (11).
Each passage (11) has an upper end laterally extending to a front
side of the body (10) to define a first opening (111) and a lower
end laterally extending to a backside of the body (10) to define a
second opening (113). The first opening (111) has an enlarged
portion (112) defined in a lower portion of the first opening (111)
and the second opening (113) has an enlarged portion (114) defined
in a top portion of the second opening (113). The enlarged portion
(112) of the first opening (111) and the enlarged portion (114) of
the second opening (113) linearly correspond to each other.
[0018] To operate the bit retainer of the present invention, a bit
is longitudinally received in a corresponding one of the series of
passages (11) and clamped between two adjacent partitions (12) for
ordering the bits. The bit is wrench toward the front side of the
body (10) and received in the enlarged portion (112) of the first
opening (111) and the enlarged portion (114) of the second opening
(113). The enlarged portions (112, 114) respectively have a
diameter slightly greater that that of the bit so that the user can
easily detach the bit from the body (10).
[0019] The bit can be simultaneously received in the enlarged
portions (112, 114) of the first opening (111) and the second
opening (113) so that the body (10) of the present invention is a
complete cuboid and has a width (W) narrower than the width (W1) of
the conventional bit retainer. Consequently, the bit retainer in
accordance with the present invention has arisen to obviate the
disadvantages of the conventional bit retainer.
[0020] Although the invention has been explained in relation to its
preferred embodiment, it is to be understood that many other
possible modifications and variations can be made without departing
from the spirit and scope of the invention as hereinafter
claimed.
