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.

Description

    BACKGROUND OF THE INVENTION
  • 1. Field of the Invention
  • The present invention relates to a retainer, and more particularly to a bit retainer.
  • 2. Description of Related Art
  • 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).
  • 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).
  • 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.
  • The present invention has arisen to mitigate and/or obviate the disadvantages of the conventional bit retainer.
  • SUMMARY OF THE INVENTION
  • The main objective of the present invention is to provide an improved bit retainer that has a small volume.
  • 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.
  • 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.
  • BRIEF DESCRIPTION OF THE DRAWINGS
  • FIG. 1 is a perspective view of a bit retainer sin accordance with the present invention;
  • FIG. 2 is a top plan view of the bit retainer in FIG. 1;
  • FIG. 3 is a side cross-sectional view of the bit retainer in FIG. 2 along line 3-3;
  • FIG. 4 is a perspective view of a conventional bit retainer in accordance with the prior art;
  • FIG. 5 is a top plan view of the conventional bit retainer in FIG. 4; and
  • FIG. 6 is a side cross-sectional view of the conventional in FIG. 5 along line 6-6.
  • DETAILED DESCRIPTION OF THE INVENTION
  • 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.
  • 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).
  • 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.
  • 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.

Claims (1)

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.
