The present invention relates to a grip device, and more particularly, to a grip device which securely accommodates hexagonal wrenches therein and the users can operate the hexagonal wrenches stably.

2. Descriptions of Related Art

The conventional connection compensating device of multi-angular wrench socket is disclosed in U.S. Pat. No. 6,791,291, and comprises a main body which is a cylindrical body. The outer circumference of the main body between two ends thereof is formed with several radially arranged flutes which extend along the circular axis of the main body by a certain length. The flutes have different cross-sectional areas. A connecting section includes a first tubular body fitted around the main body. The first tubular body is rotatable about the circular axis of the main body. The first tubular body is partially overlaid on the flutes. A geometric central axis of the profile of inner circumference of the first tubular body is not coincided with the circular axis of the main body.

There are only five flutes arranged radially along the circular axis of the main body, and flutes have different shapes of cross sections. The wrenches may have English or Metric specifications, so that the device disclosed can only use five different wrenches with the five flutes. If the users want to use more than five wrenches, at least three of the devices have to be prepared. Furthermore, when the wrench is engaged with the flute and the inner circumference of the first tubular body, the wrench may slip off from the flute during rotating, unless the user's finger contacts the lateral side of the hexagonal wrench. This makes the operation of the hexagonal wrenches awkward and inconvenient.

The present invention intends to provide a grip device that eliminates the shortcoming mentioned above.

The bottom groove151is a round cylindrical groove151, the top groove152is a rectangular groove, and the middle groove153is a rectangular groove. The bottom groove151communicates with the recess13, and the middle groove153communicates with the passage11. The width of the middle groove153is smaller than the width of the top groove152, and the width of the middle groove153is smaller than the diameter of the bottom groove151. Each of two inside walls of the passage11has a notch18defined therein, and the two notches18are perpendicular to the axis of the passage11. The notches18each are a rectangular notch which extends along the passage11, and the length of each notch18is the same as the length of the passage11. A first section51of a hexagonal wrench50can be accommodated in the passage11. The top groove152communicates with the notches18. The body10includes a half-moon-shaped chamber19which is parallel with the passage11and does not communicate with the passage11. The passage11is located between the slit12and the chamber19.

An adjustment member20has a threaded portion200formed on the outer periphery thereof. An axial hole23is defined axially through the adjustment member20. A pin30extends through the hole14of body10and the axial hole23of the adjustment member20. The adjustment member20is located in the recess13. The threaded portion200of the adjustment member20includes left threads21and right threads22, wherein the left threads21and the right threads22are opposite in threading direction.

A left slide40and a right slide400respectively and slidably located in the groove15of the body10. The left slide40including a bottom portion41, a top portion43and a middle portion45. The bottom portion41, the top portion43and the middle portion45are respectively shaped and slidable in the bottom groove151, the top groove152and the middle groove153of the groove15of the body10. Specifically, the bottom portion41is a round cylindrical portion so as to be slidable in the bottom groove151, the top portion43is a rectangular portion so as to be slidable in the top groove152, and the middle portion45is rectangular portion so as to be slidable in the middle groove153. The bottom portion41includes threads42which are engaged with the threaded portion200of the adjustment member20. Each of the left and right slides40,400has a V-shaped clamping portion44. In this embodiment, the right slide400is identical with the left slide40. The left slide40and the right slide400are respectively inserted into the groove15from two openings formed in the body10by the groove15. The left and right slides40,400are symmetrical relative to the passage11, and are respectively engaged with the two respective threads42of the left slide40and the right slide400.

When the adjustment member20is rotated relative to the pin30, the left threads21and the right threads22of the adjustment member20drive the left slide40and the right slide400to move toward the passage11so as to adjust the distance between the two clamping portions44of the left slide40and the right slide400. Therefore, the two clamping portions44of the left and right slides40,400clamp two ridges of the first section51of the hexagonal wrench50of different sizes as shown inFIG. 11.

As shown inFIGS. 7 to 10, the hexagonal wrench50is an L-shaped wrench and includes a first section51and a second section52. The first section51includes a hexagonal cross section, and the first section51is shorter than the second section52. The first section51is inserted into the passage11from the guiding slot12and slides to the groove15. When the adjustment member20is rotated relative to the pin30, the left slide40moves toward the right slide400, the two clamping portions44of the left and right slides40,400clamp two ridges of the first section51of the hexagonal wrench50. The hexagonal wrench50is then restricted by the left and right slides40,400and cannot disengage from the body10.

As shown inFIGS. 12 to 16, the second embodiment of the present invention is disclosed, wherein the bottom groove151of the groove15form two openings in the rear section100of the body10. The left slide40and the right slide400have different shapes. The right slide400is a rectangular stick with the V-shaped clamping portion. The left slide40is similar to that of the first embodiment, while the cylindrical bottom portion41is longer than that of the first embodiment. The right slide400is secured in the passage11. When the adjustment member20is rotated relative to the pin30, the left threads21of the adjustment member20are engaged with threads42of the left slide40and the left slide40moves toward the right slide400. The two clamping portions44of the left and right slides40,400clamp two ridges of the first section51of the hexagonal wrench50.

The advantages of the present invention are that when the adjustment member20is rotated relative to the pin30, the left slide40moves toward the right slide400, so that the two clamping portions44of the left and right slides40,400clamp two ridges of the first section51of the hexagonal wrench50of different sizes.

The hexagonal wrenches50may have Metric or English systems, and the two clamping portions44of the left and right slides40,400clamp two ridges of the first section51of the hexagonal wrench50regardless of the system that the wrench51may have. When the two clamping portions44of the left and right slides40,400clamp two ridges of the first section51of the hexagonal wrench50, the hexagonal wrench50is then restricted by the left and right slides40,400and cannot disengage from the body10.
