Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a handle for a wrench that can be tightened with a stronger torque than that of a straight rod.

[0002]

[Problems to be solved by conventional techniques and devices]

 In order to add torque to the wrench used when tightening or loosening the hexagon socket head cap screw, a pipe is often inserted into the short rod or long rod of the wrench to increase the turning radius. There is.

However, even in this work, there is no pipe with a good inner diameter at hand, so it is unavoidable that a pipe with a slightly larger inner diameter is inserted and turned, but if it does, it may come off during work and cause an unexpected injury. There are also many.

The present invention solves the above drawbacks and provides a handle for a wrench that can safely and reliably apply torque to a hexagon socket head cap screw.

[0005]

[Means for Solving the Problems]

 The gist of the present invention will be described with reference to the accompanying drawings.

A short rod a having a hexagonal cross-section and a long rod b having a hexagonal cross-section are connected in an L-shape, and hexagon socket bolt rotating parts a ′ and b ′ are provided at the tips of the short rod a and the long rod b. A grip handle 1 attached to a wrench A having a lock is provided with a locking portion 3 for locking the end of the wrench A when the wrench A is inserted into the inner surface of a cylindrical body 2 having a wrench body insertion hole 2 '. For the wrench characterized in that the wrench A is provided with a pressure locking portion 4 for pressing and locking the side surface of the wrench A on the inner surface of the wrench body insertion hole 2 ′, and a bulging collar portion 5 is provided on the outer peripheral surface of the cylindrical body 2. It is related to a handshake.

[0007]

[Operation] The handle 1 is fitted on the tip of one of the long rods b of the wrench A, and is inserted until the tip of the long rod b comes into contact with the locking portion 3 provided on the inner surface of the wrench body insertion hole 2 '. Increase the turning radius of wrench A. The wrench A is securely connected to the handle 1 with the side surface thereof in a tightly clamped state by the pressure locking portion 4 provided on the inner surface of the wrench body insertion hole 2 '.

In this state, insert the hexagon socket head bolt rotation part a ′ of the short rod a of the wrench A into the head of the hexagon socket head bolt and rotate the handle 1 to securely secure the hexagon socket head bolt. Tighten to.

Even if the wrench A with the product of the present invention is placed on, for example, a table, since the bulging collar portion 5 is provided on the outer peripheral surface of the tubular body 2, the grip handle 1 abuts on the table exactly. Without it, it is easy to hold the handle 1.

[0010]

【Example】

 The drawing shows the case where the cross section of the wrench body insertion hole 2'of the cylindrical body 2 has the same hexagonal cross section as the wrench A, but the point is that the wrench A is securely inserted and locked in the wrench body insertion hole 2'of the handle 1. Any shape, such as an octagon or a square, may be used as long as it has a desired shape.

Further, when picking up the handle 1, the bulging collar portion 5 is provided on the outer peripheral surface of the base of the handle 1 so that the handle can be easily handled.

The shape of the handle 1 can be modified in various ways.

[0013] Fig. 1 shows that when the handle 1 is inserted into the long rod b of the wrench A, Fig. 2 shows that the handle is attached to the short rod a of the wrench A (in this case, a so-called pole point wrench with a ball-shaped tip). This is the case when 1 is inserted.

In the drawing, a metal pipe 6 having a hexagonal cross-section is fitted in a wrench body insertion hole 2 ′ of a cylindrical body 2, and a bent locking portion 3 is provided substantially at the center in the length direction of the metal pipe 6. .

Further, a small hole 7 is bored in the upper part of the metal pipe 6, and a metal plate having a bent projection 8 for exerting a spring force is formed between the metal pipe 6 and the cylindrical body 2. A press-locking portion 4 is formed by interposing the bent projection 8 protruding from the small hole 7, and a wrench inserted into the metal pipe 6 by the spring force of the metal plate 9. The side surface of A is pressed and locked.

Reference numeral 10 in the figure is a locking bent portion.

By separately providing a core to be fitted into the wrench body insertion hole 2 ′ of the cylinder body 2, it is possible to use wrench A of each size having a different diameter with one grip handle 1. is there.

[0018]

[Effect of device]

 Since the present invention is configured as described above, it is a practically excellent wrench handle that can safely and reliably apply torque to the hexagon socket head cap screw.
