Hereinafter, a connection tool 1 and a connection method in an embodiment will be described in detail with reference to the drawings. Note that, in this specification, members having the same type of function are given the same or similar symbols. Further, repeated descriptions of members labeled with the same or similar symbols may be omitted.

As illustrated in FIG. 1, a connecting tool 1 in the embodiment is a connecting tool that connects a tool operating rod 8 and a rotary tool 9 (for example, an electric drill). The connecting tool 1 connects a tool operating rod 8 (more specifically, a tool operating rod 8 having an output shaft connecting portion 81 connected to an output shaft 91 of the rotating tool 9) and a rotating tool 9. The connecting tool 1 includes a first part P that can hold the handle part 92 of the rotary tool 9 (in other words, a handle part that is held by the operator), and a second part P that can hold the base end part 82 of the tool operating rod 8. It has a part Q. Note that an arbitrary tool for manipulating a wire such as an electric wire can be attached to the tip 83 of the tool operating rod 8 (in other words, the tip 83 of the tool operating rod 8 has a tool mounting section to which a tool can be attached). ). The tool attached to the tip of the tool operating rod 8 is, for example, a wire gripping tool, a wire cutting tool, a stripping tool for stripping the insulation coating of the wire, or the like. As the output shaft 91 of the rotary tool 9 rotates, the output shaft connecting portion 81 of the tool operating rod 8 is rotated. The rotation of the output shaft coupling portion 81 is transmitted to the tool attached to the tip of the tool operating rod 8 via the driving force transmission mechanism of the tool operating rod 8 . In this way, a wire such as an electric wire is manipulated (for example, gripped and cut) by the end effector (for example, a gripping section, a cutting blade, etc.) of the tool attached to the tip of the tool operation rod 8. The tool operating rod 8 in the embodiment is, for example, an insulated operating rod in which at least the outer peripheral surface of the base end portion 82 is formed of an electrically insulating material.

(First embodiment)
A connecting tool 1A according to the first embodiment will be described with reference to FIGS. 2 and 3. FIG. 2 is a schematic two-sided view of the connecting tool 1A in the first embodiment. A schematic plan view of the connecting tool 1A is shown on the upper side of FIG. 2, and a schematic side view of the connecting tool 1A is shown on the lower side of FIG. FIG. 3 is a schematic plan view of the connecting tool 1A in the first embodiment.

As illustrated in FIG. 2, the connecting tool 1A in the first embodiment has a first portion P that can hold the handle portion 92 (see FIG. 1) of the rotary tool 9 and can be separated from the handle portion 92. and a second portion Q that can hold the base end 82 (see FIG. 1) of the tool operating rod 8 and that can be separated from the base end 82.

In the example shown in FIG. 2, the connecting tool 1A includes a first portion P that can hold the handle portion 92 of the rotary tool 9 and that can be separated from the handle portion 92. Therefore, the connecting tool 1A can be easily attached to the handle portion 92 of the rotary tool 9, and the connecting tool 1A can be easily removed from the handle portion 92 of the rotary tool 9.

In the example shown in FIG. 2, the connecting tool 1A includes a second portion Q that can hold the base end portion 82 of the tool operating rod 8 and that can be separated from the base end portion 82. Therefore, the connecting tool 1A can be easily attached to the base end 82 of the tool operating rod 8, and the connecting tool 1A can be easily removed from the base end 82 of the tool operating rod 8. .

It is assumed that an operator rotates the output shaft 91 of the rotary tool 9 while holding the handle portion 92 of the rotary tool 9 without using the connecting tool 1A. In this case, when the end effector of the tool attached to the tip of the tool operating rod 8 comes into contact with the workpiece (for example, an electric wire), the output shaft 91 of the rotary tool 9 is connected to the output shaft of the tool operating rod 8. A large reaction force (large torque) acts from the connecting portion 81. The torque is supported by the operator who grips the handle portion 92 of the rotary tool 9, which places a heavy burden on the operator. On the other hand, in the example shown in FIG. 2, the handle portion 92 of the rotary tool 9 can be held by the connecting tool 1A. Therefore, even when the operator takes his hand off the handle part 92 (or just puts his hand on the handle part 92), the connected tool 1A allows the rotary tool 9 to It is possible to support the reaction force received from 8. In other words, the connected tool 1A effectively prevents the entire rotary tool 9 from rotating around the output shaft 91 due to the reaction force that the rotary tool 9 receives from the tool operating rod 8.

The connecting tool 1A in the first embodiment connects the base end portion 82 of the tool operating rod 8 and the handle portion 92 of the rotary tool 9. Therefore, in the first embodiment, there is no need to prepare various connecting tools in accordance with the shape of the output shaft 91 of the rotary tool 9 and the shape of the members arranged around the output shaft 91. In other words, the shape of the handle portion 92 of the rotary tool 9 is formed to fit the operator's hand, so the shape of the handle portion 92 of the rotary tool 9 depends on the type of the rotary tool 9. It is generally constant. Therefore, the connecting tool 1A in the first embodiment can be used to connect various types of rotary tools 9 and tool operating rods 8.

Further, the connecting tool 1A in the first embodiment connects the base end portion 82 of the tool operating rod 8 and the handle portion 92 of the rotary tool 9. In this case, as illustrated in FIG. 1, the output shaft 91 of the rotary tool 9 and the connected tool 1A will be sufficiently separated. When the output shaft 91 of the rotary tool 9 and the connected tool 1A are sufficiently separated, stress (more specifically, In this case, the stress generated in the connecting tool 1A can be small. Therefore, there is a small risk that the connected tool 1A in the first embodiment will be damaged or deformed due to the torque (torque around the output shaft 91) that the rotary tool 9 receives from the tool operating rod 8.

Further, when a battery is disposed in the handle portion 92 of the rotary tool 9, when the rotary tool 9 rotates around the output shaft 91, a large centrifugal force will be generated in the rotary tool 9. In contrast, the connection tool 1A in the first embodiment directly supports the vicinity of the battery. Therefore, rotational movement of the handle portion 92 around the output shaft 91 is effectively suppressed. The connecting tool 1A may support a portion of the handle portion 92 of the rotary tool 9 between the output shaft 91 of the rotary tool 9 and the battery of the rotary tool 9. In this case, rotational movement of the handle portion 92 around the output shaft 91 is effectively suppressed, and the connecting tool 1A does not get in the way of battery replacement.

A possible second holding part P2 is provided. In this case, in order to clamp the handle part 92 by the first portion P, the distance between the first clamping part P1 and the second clamping part P2 may be reduced. Furthermore, in order to separate the first portion P from the handle portion 92, the distance between the first clamping portion P1 and the second clamping portion P2 may be increased.

In this case, in order to clamp the proximal end part 82 by the second portion Q, it is sufficient to reduce the distance between the third clamping part Q1 and the fourth clamping part Q2. Furthermore, in order to separate the second portion Q from the base end portion 82, the distance between the third clamping portion Q1 and the fourth clamping portion Q2 may be increased.

Since the fourth clamping member 12c is soft, the base end portion 82 is effectively held by the fourth clamping member 12c. The fourth holding member 12c is made of resin, for example. In the example shown in FIG. 2, the fourth holding member 12c is attached to the base member 12a. The fourth holding member 12c may include a concave surface 112c that contacts the base end portion 82 of the tool operating rod 8. It is preferable that the concave surface 112c is concave in the opposite direction to the concave surface 111c. In this case, the base end portion 82 of the tool operating rod 8 is received within the receiving space formed by the concave surface 111c and the concave surface 112c.

In this case, a series of steps from the step of inserting the proximal end portion 82 of the tool operating rod 8 into the connecting tool 1A to the step of holding the proximal end portion 82 by the connecting tool 1A can be smoothly executed.

In the example shown in FIG. 2, the second connecting member 15-2 is connected to the first elongated member 11 so as to be swingable about the second axis AX2. Alternatively, the second coupling member 15-2 may be coupled to the second elongate member 12 so as to be swingable about the second axis.

In the example shown in FIGS. 2 and 3, the second connecting member 15-2 is moved to the above-mentioned connecting position by moving the second connecting member 15-2 in the third rotation direction R3 around the second axis AX2. The position is changed from the above-mentioned open position. On the other hand, moving the second connecting member 15-2 around the second axis AX2 in a fourth rotational direction R4 (more specifically, a fourth rotational direction R4 that is opposite to the third rotational direction R3). As a result, the second connecting member 15-2 is changed from the above-mentioned open position to the above-mentioned connected position. Note that in the example shown in FIG. 2, the second axis AX2 is an axis perpendicular to the longitudinal direction of the first elongated member 11.
