As described above, the extension pipe described in Patent Document 1 has a problem that it cannot transmit rotational torque.
An object of the present invention is to provide a separation operation tool that can solve such a problem and can transmit a rotational torque by an extension vip.

The present invention has been made for the purpose of solving the above-described problems, and is configured as follows.
(1) A separation operation tool for rotating a rotation operation handle of a device or instrument in a high place or a separation place such as a ceiling and having a length from a hand to the rotation operation handle The tip of the rod-shaped member is provided with a conical cup-shaped or diverging-shaped shade that opens upward, and a rotation engaging portion that is covered with rubber on the upper surface of the cup-shaped or shade-shaped portion is provided. Rotational torque applied to the rod-shaped member can be transmitted by pressing the upper surface of the rotation engaging portion against the rotation operation handle, and a connecting portion that can be connected to the output portion of the rotary prime mover is provided at the base end portion of the rod-shaped member. A separation operation tool provided and configured to transmit a rotation torque of a rotary prime mover to the operation handle via the rotation engagement portion.
(2) In the separation operation tool described in (1), the rod-shaped member is a round bar or a pipe material, and the rotary prime mover is one selected from an electric motor, a fluid pressure rotary motor, or an electric drill, and further rotates. Separation operation tool in which a plurality of rubber plates having a predetermined shape and a predetermined thickness are arranged on the circumference of a portion of the upper surface of the rotation engagement portion that comes into contact with the operation handle, instead of the rubber covering the upper surface of the engagement portion. .
(3) The separation operation tool according to (1) or (2), wherein the rotary prime mover is capable of forward / reverse rotation and adjustable rotational torque.
(4) The pipe material as the rod-shaped member in the separation operation tool according to any one of the items (1) to (3) is provided with a gripping portion as a connection portion at a base end portion thereof, and the gripping portion A tool for separating operation with an electric drill, in which a chuck of an electric drill as a rotary prime mover is held.

Since this invention is comprised as mentioned above, there exists an effect described below.
The separation operation tool of the present invention is provided with a rotation engaging portion at the tip of a rod-like member such as a long pipe, pressed against a rotation operation handle at a high place, and transmits torque applied to the pipe. Since it can be rotated, for example, when opening and closing an exhaust duct such as a building, there is an advantage that work requiring a stepladder, ladder, etc. is not required, labor can be reduced, and work safety can be improved. .

In addition, the rotary engagement part has a conical or divergent cup shape that opens upward, and the diameter of the cup-shaped part changes depending on the depth position, so there is an advantage that it can be used for various sizes of rotary operation handles. When the rotation engagement portion is pressed against the rotation operation handle, the rotation operation handle is guided by the cup-shaped inclined surface of the rotation engagement portion, so that the two can be naturally aligned, so that it is easy to use. .
Furthermore, since the separation operation tool of the present invention can be driven and rotated by a rotary prime mover such as an electric drill, there is an advantage that the above operation can be performed at high speed and simply.

Furthermore, by forming the rubber covering portion on the entire portion of the upper surface (cup-shaped portion) of the rotation engagement portion that is in contact with the rotation operation handle, there is an advantage that the rotation operation handle is less likely to slip during use. Further, there is an advantage that the present invention can be applied not only to a circular shape but also to a polygonal handle.
In addition, since the rotational force is transmitted to the operation handle using an appropriate friction between the rubber and the operation handle, it slips when an excessive force is applied, and the operation handle is not forced.

  (B) is an enlarged view of a portion A in FIG. (A), and (C) is a P view in FIG. (A). .

  The present invention uses a long rod-like member for the purpose of operating a rotary operation handle of a device or instrument in a high place or a remote place, and is provided with a conical cup-like rotary engaging portion at the tip thereof This was achieved by devising a remote operation tool that requires a small number of points.

Embodiments of the present invention will be described below in detail with reference to the drawings.
In FIG. 1, reference numeral 10 denotes a separation operation tool. A conical rotational engagement portion 14 is provided at the distal end portion of the conduction pipe 12, and a connection member 16 for connecting to an electric drill at the proximal end portion of the pipe. Is attached.
The connecting member 16 has a gripping portion 17 projecting from the center of a short columnar portion fitted into the conductive vibrator 12, and a pin, a screw or the like with the short columnar portion fitted into the conductive pipe. It is fixed to the conduction pipe 12.

  On the other hand, the conduction pipe 12 is a long member having such a length that it can reach the rotary operation handle of devices and instruments located at a high place from the user's hand, and is opened upward at the tip thereof. A rotation engaging portion 14 is provided. The rotation engagement portion 14 has a plurality of anti-slip rubber plates 20 arranged on the upper surface of a conical cone portion 18 in a substantially equal manner on the circumference. Since the rotation engaging portion 14 is pressed against the rotation operation handle 22 and transmits the rotation torque of the conduction pipe 12 in use, it is not slippery to cope with various diameter sizes of the rotation operation handle 22. It is desirable that the rubber plate 20 has a size having a margin in the depth direction of the cone portion 18.

  The cone portion 14 tapers upward, and if the angle between the two sides of the cross section along the central axis, that is, the so-called taper angle is narrowed, the rotation of the rotary engagement portion 14 during use is reduced. The axis and the rotation axis of the rotary operation handle are easy to match, so-called centering is easy and easy to use, and torque is easily transmitted, but if the diameter size of the rotary operation handle 22 changes slightly, the cone The use position of the portion 18 becomes deeper or shallower, and it is sensitively affected. If it becomes deeper, the outer edge of the cone portion 18 may interfere with devices, instruments, etc. in the vicinity of the rotary operation handle and may become unusable.

  On the other hand, when the taper angle is increased, it is difficult to align the rotation axis of the rotation engagement portion 14 and the rotation axis of the rotation operation handle 22 during use, which makes it difficult to use and transmission of torque is difficult. Become. Therefore, the taper angle of the cone portion 18 and the aperture size of the cone portion 18 should be determined in consideration of these matters.

  In the embodiment configured as described above, the grip portion 17 of the separation operation tool 10 is chucked to the chuck portion of the electric drill, and the cone portion 18 of the rotation engagement portion 14 is pressed against the rotation operation handle 22. When the switch is turned on, the rotational torque of the conduction vibrator 12 is transmitted to the rotary operation handle to rotate, and the operation of the machinery and equipment at a high place is performed.

  In the above embodiment, the entire upper surface (inner surface) of the cone portion 18 may be covered with rubber instead of the plurality of anti-slip rubber plates 20 disposed on the cone portion 18.
