Abstract

<P>PROBLEM TO BE SOLVED: To provide a ratchet handle driven by power such as air capable of safely being used at a narrow place by making the position of a drive head and a rotation adjustment lever possible to be arbitrarily set. <P>SOLUTION: The position adjustment of the drive head 1 and a main body 3, and the arbitrary setting of the position of the rotation adjustment lever 4 mounted to the main body relative to the drive head are made possible by attaching a spring washer 5 to the inside of the drive head 1 and a mounting nut 2 of the main body 3. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a ratchet wrench driven by power such as air.

  Conventionally, the ratchet wrench driven by air etc. has been fixed in the position of the drive head and the rotation adjustment lever, but the lever interferes with the obstacle, the rotation does not stop, and there is a danger such as pinching the hand, and it is used in a narrow place Although there was a drawback that it was not possible, there was no power drive ratchet handle that could change the position of the drive head and rotation adjustment lever.

  The problem to be solved is that the positions of the drive head and the rotation adjusting lever cannot be changed.

  The main feature of the present invention is that the rotation adjustment lever attached to the main body can be set at an arbitrary position by making the attachment portion of the drive head and the main body movable.

  The power drive ratchet handle with swing function according to the present invention can arbitrarily set the position of the rotation adjustment lever with respect to the drive head, so that it can be set at a position where an obstacle does not interfere with the rotation adjustment lever, so that the operation in a narrow place is possible. There is an advantage that becomes possible.

  The position of the drive head and the rotation adjustment lever can be set arbitrarily to avoid the danger of the rotation adjustment lever interfering with an obstacle and preventing the rotation from stopping and pinching your hands.

  FIG. 1 is a three-dimensional view of one embodiment of the present invention, showing the positional relationship between a drive head and a rotation adjusting lever.

  FIG. 2 is a side view including a partial cross-sectional view of FIG. 1 and shows the same movement as that of FIG. 1. This shows how the positions of the one drive head and the four rotation adjusting lever can be arbitrarily set by attaching the two attachment nuts to the three main bodies in a state in which the one drive head is movable.

  Since the position of the drive head and rotation adjustment lever can be set arbitrarily, the rotation adjustment lever can be set so that it does not interfere with obstacles when using the power drive ratchet in a narrow place. Since it can be avoided, it can be applied to applications in narrower spaces.

It is the three-dimensional view which showed the motion of the power drive ratchet handle with a swing function. It is a side view including a partial sectional view of a power drive ratchet handle with a swing function.
