Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handle which can be used for a driver for tightening a screw or the like, and more particularly to a handle which gives a high torque.

[0002]

2. Description of the Related Art In a conventional driver, only a tool for tightening a screw is attached to the tip of an elongated handle portion, and a large force is required to tighten the screw. Further, in a box wrench or the like, a rod (lever) that is orthogonal to the axis of the wrench and applies a large torque is provided. Takes up space with large size.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a high torque handle that can be used for a driver or the like. When used, the handle can be protruded from the handle to apply a large torque, and can be stored in the handle when not in use. An object of the present invention is to provide a high torque handle having a grip.

[0004] A high torque handle according to an embodiment of the present invention includes:
An elongate notch formed parallel to the handle axis, an elongate grip received in the notch, and a pin disposed in the notch and connected to one end of the grip. The grip is rotated about a pin and removed from the handle notch and used to provide high torque. Other embodiments and features of the present invention will be apparent from the following embodiments of the present invention.

[0005]

FIG. 1 shows a preferred embodiment of a high torque handle 10 of the present invention. High torque handle 1
0 has a hole 14 at one end for firmly holding the tool holder in the hole. As shown in FIG. 3, the tool holder 12 has a plurality of raised ridges 1 near its one end.
These ridges 16 are provided slightly larger than the size of the holes 14 so that the handle 10 firmly holds the holder. As shown in FIGS. 1 and 2, a Phillips head screwdriver (cross-head screwdriver) tool 18
Is held in the tool holder 12. As best seen in FIG. 5, another plurality of hex holes 19 are provided remote from the holes 14 to hold spare hex tools 18 in those holes when not in use.

In a portion near the other end of the handle 10,
The rotatable hand grip 20 rotates around a spring pin 22. The spring pin 22 is sized to hold the grip 20 at any desired rotational position.
The handgrip 20 is extended for use as an additional lever when turning the handle 10. The handgrip 20 is also drawn into a notch 24 formed in the handle. The ridge 26 extends along the handle 10 at the bottom of the notch 24 when the hand grip 20 is retracted. The ridge 26 acts as a stopper for the handgrip 20 when the handgrip 20 rotates and is drawn into the handle 10. The finger is engaged with the lip 28 of the grip 20 to
Notch 2 so that the
The length of 4 is suitable.

The tool holder 12 has a hex opening 30 at one end for receiving the tool 18 therein. As shown in FIG. 7, in a preferred embodiment, a hexagonal aperture 3
A magnet is provided near the bottom of the 0 to hold the tool 18 in the opening 30.

FIG. 8 shows another embodiment of the tool holder 12.
Shown in Since a plurality of ridges 16 slightly larger than the hole 14 in the handle are provided near one end, the tool holder can be firmly held in the handle. At the other end of the tool holder 12, the movable sleeve 34 locks or unlocks the ball 36. Ball 36 is used to lock another tool 18 in hex socket 30. This locking mechanism is the same as that disclosed in FIGS. 4A and 4B and the specification of U.S. Pat. No. 5,470,180 to Jore.

While the basic new features of the invention have been illustrated and described, it will be apparent to those skilled in the art that various modifications can be made without departing from the scope of the invention (ie, the inventive concept). It is obvious. Therefore, the present invention includes such modifications in the scope of the claims.
