[0124] For indirect live wire installation, the insulating operating rod only needs to have electrical insulation properties, and it is even better if it can be lightweight. For example, various plastics with high toughness, such as fiber-reinforced plastics (FRP), can be used.

[0125] The front-end tools 14 for indirect live wire construction include, for example, a stripping machine, pliers, and clamping parts for stripping the insulation film off overhead distribution wires in the live wire state.

[0126] The front-end tool 14 has a tool part 30 that is in direct contact with wires, etc., and a connecting part 32 (on the front-end tool side) formed in the area that connects the tool part 30 to the operating rod 12, constituting the connected part.

[0127] The connecting portion 24 on the operating rod 12 side of the rod body and the connecting portion 32 on the connected portion side are arranged concentrically with the center line extending in the axial direction of the rod body, with a protrusion formed on one side and a concave portion formed on the other side, and the protrusion and concave portion are combined to form a connection.

[0128] In this embodiment, a core member 44 constituting a protrusion is formed in the connecting portion 24 (on the operating rod side), and a rod-side connecting portion mounting hole 94 constituting a recess is formed in the connecting portion 32 (on the front tool side).

[0129] The core component 44 is a rod-shaped body with a roughly circular cross-section, and the mounting hole 94 of the connecting part on the rod side is an annular body with a roughly circular cross-section. The core component 44 is assembled into the mounting hole 94 of the connecting part on the rod side, and the connecting part 24 on the operating rod 12 side and the connecting part 32 on the connected part side are connected.

[0130] The operating rod 12 is provided with a fixing means 16 in the area on the side connected to the front tool 14, which is a means of preventing separation of the components connected by the connecting structure.

[0131] Furthermore, in the region where the operating rod 12 is connected to the front tool 14, there is a restraining means 18 that prevents the movement of the operating rod 12 and the front tool 14 from disengaging, and prevents the components connected by the connecting structure from separating, thus constituting a separation prevention means.

[0132] The connecting part 24 of the operating rod 12 that constitutes the connecting part of the rod body is composed of a first connecting part 40 that is thinner than the operating rod body 20 and is formed on the side connected to the operating rod body 20, and a core member 44 that is thicker than the first connecting part 40 is continuously provided on the tool 14 side of the front end of the first connecting part 40.

[0133] The core member 44 of the connecting part 24 (on the operating rod side) that constitutes the operating rod body 20 is connected to the operating rod body 20 via the (first) operating rod mounting member 26 that constitutes the operating rod mounting member and the fixing pins 26a and 26b.

[0134] In this embodiment, such as Figure 3 As shown in (C), the (first) operating rod mounting member 26 and the core member 44 are embedded in the recess 20a on the front end side of the operating rod body 20 and are fixed by fixing pins 26a and 26b.

[0135] The first connecting portion 40 of the core component 44 is nested around the (first) operating rod mounting component 26 and embedded in the recess 20a provided at the front end of the operating rod body 20, and is fixed to the operating rod body 20.

[0136] In this embodiment, the connecting portion 24 (on the operating rod side) includes a core member 44 that constitutes the first connecting portion 40 and the second connecting portion 42.

[0137] The core component 44 is a hollow cylindrical shape and is disposed around the (first) operating rod mounting component 26 and the (second) operating rod mounting component 28 that constitute the operating rod mounting component.

[0138] In this embodiment, regarding the core member 44, the hand side is formed with a first connecting portion 40, which is formed by a cylindrical portion thinner than the operating rod body 20 and is mounted to the operating rod body 20, and the front end side is formed with a second connecting portion 42, which is formed by a thicker cylindrical portion and is thicker than the first connecting portion 40 thinner than the hand side.

[0139] The core member 44 has a shape that allows it to be inserted into a rod-side connection mounting hole 94 formed in a cavity provided in the second connection portion 84 of the second connecting member 80. In this embodiment, it is configured as a cylindrical shape that can slide within the cavity.

[0140] The core component 44 has a hollow annular portion 46 that extends through the length direction.

[0141] The hollow portion 46 has a first hollow portion 46a that is elongated and narrowed at its center, and a second hollow portion 46b that is thicker and has a longer diameter than the first hollow portion 46a is formed on the front end side of the hollow portion 46a.

[0142] Furthermore, on the hand-side side of the hollow portion 46, a thicker third hollow portion 46c with a diameter longer than that of the first hollow portion 46a is formed.

[0143] The core component 44 is provided with an operating rod mounting component ((first) operating rod mounting component 26) for mounting to the operating rod body 20 in the third hollow portion 46c of the hollow portion 46.

[0144] The operating rod mounting component ((first) operating rod mounting component 26) is fixed to the front end of the operating rod body 20, and the third hollow part 46c of the core component 44 is nested around the (first) operating rod mounting component 26 for installation.

[0145] (Second) The operating rod mounting member 28 is inserted into the hollow part 46, with its hand side located in the third hollow part 46c. It is slidably embedded in the first hollow part 46a relative to the front end side of this part. Furthermore, the front end side of this part extends towards the front end side in the second hollow part 46b and connects with the columnar core member mounting part 96.

[0146] In this embodiment, the (second) operating rod mounting member 28 is a cylindrical rod with a head on the hand side that has a diameter larger than that of the first hollow portion 46a, and a rod-shaped body on its front end that has a diameter almost the same as that of the first hollow portion 46a. Therefore, the second hollow portion 46b is configured such that a hollow portion remains between it and the (second) operating rod mounting member 28, in which the third rebound member 98 can be inserted.

[0147] The connecting portion on the rod side and the connecting portion on the connected side are configured such that a first fixing protrusion 60 is formed on one side as a fixing means 16 constituting a protrusion, and a first fixing groove 90 is formed on the other side as a fixing means 16 constituting a recess. The protrusion and the recess are combined to form a connection.

[0148] The fixing means 16 is composed of a first fixing protrusion (pin) 60 formed on the connecting part of the rod body, which constitutes a separation prevention means.

[0149] The fixing means formed in the second connecting member 80 or the fixing means 16 formed in the core member 44 are constituted by a first fixing groove 90, which is a tortuous fixing groove formed at a corresponding position in the core member 44 and / or the second connecting member 80, serving as a means of preventing separation.

[0150] In this embodiment, the core member 44 is fitted with a first fixing protrusion (pin) 60 constituting the fixing means 16 on the side of the second connecting portion 42, and a rebound member 70 constituting the suppressing means 18 is inserted around the first connecting portion 40.

[0151] The connecting part 24 (on the control stick side) has a core member 44 fixed at the center of the front end of the control stick body 20, and a first connecting member 50 is arranged around the core member 44.

[0152] Furthermore, the connecting part 24 (on the operating rod side) is provided with a restraining means 18 around the hand side of the core member 44, which is formed to rebound from the hand side of the operating rod 12 toward the front tool 14 side and is composed of a rebounding member 70 such as a coil spring.

[0153] In this first embodiment, a rebound member mounting portion 72 for stopping the front end of the rebound member 70 is formed on the hand side of the first connecting structure member 50.

[0154] Furthermore, on the side of the operating rod body 20 of the operating rod 12 facing the outer surface of the first connecting structure 50, a rebound member mounting part 74 for stopping the rear end side of the rebound member 70 is formed on its front end side.

[0155] The rebound member 70 constituting the suppression means 18 is configured such that when the front end tool 14 is installed onto the operating rod 12, it applies force to the first connecting member 50 on the side of the second connecting member 80 constituting the connected part.

[0156] When locked, the first rebound member 70 constituting the restraining means 18 presses the first connecting structural member 50 towards the front end, and simultaneously presses the second connecting structural member 80 towards the front end. (Types 1, 3, 4)

[0157] The diameter of the suppressing means 18 (rebound member 70) is shorter than the diameter of the first connecting structural member 50 and the rebound member mounting part 74, so that it will not be ejected from the first connecting structural member 50 and the rebound member mounting part 74.

[0158] Therefore, the probability of the suppression method 18 encountering other objects when in use is extremely low.

[0159] The first connecting part 40 is configured to form a movable space between itself and the operating rod body 20 for the first connecting member 50 (described later). The second connecting part 42 is provided with the first fixing protrusion (pin) 60 and is configured to allow the second connecting member 80 constituting the connecting part 32 (on the front tool side) to be inserted around it.

[0160] The first connecting structural member 50 is annular and nested around the roughly cylindrical core member 44. It is configured to move freely in the length direction of the core member 44 and the operating rod body 20, and is configured to be bounced towards the front end by a rebound member 70 inserted between the hand side of the first connecting structural member 50 and the front end side of the operating rod body 20.

[0161] The first fixed protrusion (pin) 60 is formed in the center of the connecting portion 24 (on the operating rod side) and extends radially.

[0162] The first fixed protrusion (pin) 60 is configured to be able to move axially in relation to the front end tool 14 as the operating rod 12 moves, and is configured to be able to rotate circumferentially in relation to the operating rod 12 as the operating rod 12 rotates.

[0163] The connecting part 32 (on the front tool side) constitutes the mounting part for mounting to the operating rod 12, and is provided with a second connecting member 80 that is configured to connect the connecting part 24 on the operating rod 12 side.

[0164] The second connecting member 80 has a first fixing groove 90 in the region on the side connected to the operating rod 12, which serves as a fixing means 16 for stopping the first fixing protrusion (pin) 60 disposed on the connecting part 24 on the operating rod 12 side. The first fixing groove 90 allows the first fixing protrusion (pin) 60 to be inserted, thus forming a fixing means 16 for fixing the first fixing protrusion (pin) 60 when the connecting part 24 (on the operating rod side) and the connecting part 32 (on the front tool side) are connected.

[0165] The first connecting structural member 50 and the second connecting structural member 80 have almost the same or similar shapes. In this embodiment, they are cylindrical in cross-section and have the same or similar diameters on their outer surfaces.

[0166] Therefore, there are basically no steps at the boundary between the second structural component 80 and the first structural component 50, and the probability of encountering other objects is extremely low.

[0167] The first connecting structural member 50 and the second connecting structural member 80 are configured such that their contact surfaces are in close contact, and the first connecting structural member 50 uses the force applied by the restraining means 18 (rebound member 70) to press the second connecting structural member 80.

[0168] In this embodiment, the front end face 50E of the first connecting member 50 is a plane orthogonal to the axial direction, and the rear end face 80E of the second connecting member 80 is a plane orthogonal to the axial direction. Therefore, the front end face 50E of the first connecting member 50 and the rear end face 80E of the second connecting member 80 are in close contact.

[0169] The surface of the rebound member mounting portion 72 at the rear end of the first connecting structural member 50 that faces the rebound member mounting portion 74 is a plane orthogonal to the axial direction. On the other hand, the surface of the front end of the rebound member mounting portion 74 that faces the rebound member mounting portion 74 is a plane orthogonal to the axial direction. The restraining means 18 (rebound member 70) sandwiched between them is configured to apply force to the first connecting structural member 50 parallel to the axial direction.

[0170] The diameter of the suppressing means 18 (rebound member 70) is shorter than the diameter of the first connecting structural member 50 and the rebound member mounting part 74, so that it will not be ejected from the first connecting structural member 50 and the rebound member mounting part 74.

[0171] The first fixing groove 90 has a first groove portion 90A that opens to the side of the operating rod 12, a second groove portion 90B that opens to the first groove portion 90A, and a third groove portion 90C that opens to the second groove portion 90B. The first groove portion 90A extends in the length direction, the second groove portion 90B extends in the circumferential direction, and the third groove portion 90C extends in the length direction and becomes a dead end.

[0172] The first fixing groove 90 is formed in the shape of an L when viewed from above, and is configured such that when the front tool 14 is installed onto the operating rod 12, the first fixing protrusion (pin) 60 stops in the third groove 90C and does not move.

[0173] The first fixing groove 90 has a depth in which the head of the first fixing protrusion (pin) 60 protrudes slightly and a width in which the shaft portion of the first fixing protrusion (pin) 60 can move.

[0174] Based on the above configuration, the second connecting member 80, at the bottom of the third groove 90C, uses the force applied by the rebound member 70 and the second rebound member 76 to press the fixing means 16 (first fixing protrusion (pin) 60) that is radially protruding and fixed in the second connecting part 42 of the first connecting part 40 connected to the operating rod body 20 toward the front end side (the mounting part), thereby engaging the third groove 90C and the fixing means 16 (first fixing protrusion (pin) 60), so that the second connecting member 80 will not move in the locking release direction.

[0175] The first fixing protrusion (pin) 60 is provided to protrude radially from the first connecting structural member 50.

[0176] The first fixing groove 90 has a depth in which the head of the embedded first fixing protrusion (pin) 60 protrudes slightly, and a width in which the shaft portion of the embedded first fixing protrusion (pin) 60 can move.

[0177] The first groove 90A extends in such a way that the fixing means 16 (first fixing protrusion (pin) 60) can move forward toward the front end, that is, it extends toward the direction of connecting the operating rod 12 to the front end tool 14. In this embodiment, it is formed by a groove parallel to the axial direction.

[0178] The second groove 90B has a length that allows the fixing means 16 (first fixing protrusion (pin) 60) to advance radially from the first groove 90A to a position where it will not return to the first groove 90A. In this embodiment, it is formed by a groove orthogonal to the axial direction.

[0179] The first groove 90A, the second groove 90B, and the third groove 90C are grooves with approximately the same width, each forming an L-shaped bend.

[0180] Their width and depth are configured to allow the first fixed protrusion (pin) 60 and the second fixed protrusion (plunger) 62 to advance in the extension direction of the groove while in the embedded state.

[0181] The third groove 90C extends in a manner that allows the fixing means 16 (first fixing protrusion (pin) 60) to advance towards the hand side, that is, towards the opposite side of the direction in which the operating rod 12 is connected to the front tool 14. As a result, the fixing means 16 (first fixing protrusion (pin) 60) that has advanced along the second groove 90B to a position where it will not move radially will not advance further towards the opposite side of the direction of connection, thus becoming a dead end.

[0182] The fixing means 16 (first fixing protrusion (pin) 60) is fixed to the recess that constitutes the second connecting part 42. The part that protrudes from the outer surface of the recess that constitutes the second connecting part 42 is the part that functions as a fixing protrusion.

[0183] The second connecting member 80 constitutes a mounting part that is installed to the (front end) tool part 30 and connected to the operating rod 12, and includes a first connecting part 82, which is installed to the (front end) tool part 30 as a front end tool mounting part, and a second connecting part 84 that is thicker than the first connecting part 82, which is the front end tool mounting part.

[0184] The first connecting part 82 is fitted into the mounting part of the (front end) tool part 30 and is fixed to the (front end) tool part 30 by a suitable fastener (e.g., a pin).

[0185] The second connecting part 84 constitutes a hollow core component mounting part, and has a rod-side connecting part mounting hole 94 for the core component 44 to be inserted.

[0186] The second connecting part 84 has a columnar core component mounting part 96 provided in the mounting hole 94 of the connecting part on the rod body side.

[0187] The columnar core component mounting portion 96 is inserted into the annular hollow portion 46 between the second connecting portion 42 of the core component 44 and the (second) operating rod mounting component 28, and is connected to the front end side of the (second) operating rod mounting component 28.

[0188] (Second) The operating rod mounting component 28 and the columnar core component mounting part 96 are arranged in a row and are installed at the second connecting part 42 of the core component 44.

[0189] The columnar core component mounting portion 96 is configured to abut against the handle side of the second connecting member 80. A second rebound member 76 is provided in the second hollow portion 46b, which exists between the handle side end of the columnar core component mounting portion 96 and the boundary wall of the first hollow portion 46a of the hollow portion 46. The second rebound member 76 is formed of a helical spring or the like, which is configured to rebound the columnar core component mounting portion 96 toward the handle side or the front end side.

[0190] The second rebound member 76, constituting the restraining means 18, retracts during locking, pressing the core member mounting portion 96 and the second connecting portion 84 towards the front end. (Types 1-3)

[0191] In its normal state, the second rebound component 76 presses the core component mounting part 96 and the second connecting part 84 towards the front end. In the locked state, it becomes slightly retracted. When the second connecting component 80 is pulled towards the front of the hand by the release action, it becomes further retracted.

[0192] like Figure 3 As shown in (B), the columnar core component mounting part 96 is embedded in the hollow part 46 of the second connecting part 42 and fixed to the (second) operating rod mounting part 28 by means of the anti-loosening screw 28a.

[0193] The columnar core component mounting portion 96 has a shape that fits into a second hollow portion 46b formed in a cavity provided in the second connecting portion 42, and in this embodiment it is configured to be cylindrical and capable of sliding within the cavity.

[0194] The columnar core component mounting part 96 has a bottom hole on its hand side, which is configured to allow the (second) operating rod mounting part 28 to be fitted, and is configured to allow the (second) operating rod mounting part 28 to be connected to the columnar core component mounting part 96.

[0195] The columnar core component mounting portion 96 has a shape that fits into a second hollow portion 46b formed in a cavity provided in the second connecting portion 42, and in this embodiment it is configured to be cylindrical and capable of sliding within the cavity.

[0196] The columnar core component mounting part 96 has a bottom hole on its hand side for the (second) operating rod mounting part 28 to fit into, thus enabling the (second) operating rod mounting part 28 to be connected to the columnar core component mounting part 96.

[0197] (Second) The operating rod mounting component 28 extends to the hand side of the columnar core component mounting part 96, and a second rebound component 76 is inserted around it. The head of the second hollow part 46c protrudes and is fixed to the first hollow part 46a and is mounted in the second hollow part 46b.

[0198] The first connecting structural member 50 and the second connecting structural member 80 have almost the same or similar shapes. In this embodiment, they are cylindrical in cross-section and have the same or similar diameters on their outer surfaces.

[0199] Therefore, there are basically no steps at the boundary between the second structural component 80 and the first structural component 50, and the probability of encountering other objects is extremely low.

[0200] The first connecting structural member 50 and the second connecting structural member 80 are configured such that their contact surfaces are in close contact, and the first connecting structural member 50 presses the second connecting structural member 80 with a uniform force by applying force through the restraining means 18 (rebound member 70).

[0201] The surface of the rebound member mounting portion 72 at the rear end of the first connecting structural member 50 that faces the rebound member mounting portion 74 is a plane orthogonal to the axial direction. On the other hand, the surface of the front end of the rebound member mounting portion 74 that faces the rebound member mounting portion 74 is a plane orthogonal to the axial direction. The restraining means 18 (rebound member 70) sandwiched between them can apply force to the first connecting structural member 50 by means of a force parallel to the axial direction.

[0202] The first connecting member 50 is disposed on the operating rod 12 in such a way that it can move axially. It is configured such that when the front end tool 14 is installed on the operating rod 12, it is fixed to the area of ​​the second connecting member 80 on the operating rod 12 side to control the movement of the second connecting member 80, so as to prevent the connecting part 24 (on the operating rod side) from disengaging from the first fixing groove 90 of the second connecting member 80.

[0203] The first connecting structural member 50 has a fixing means 16 for controlling the movement of the second connecting structural member 80.

[0204] The fixing means 16 of the core member 44 is provided with an external thread 48 on the outer periphery of the area where the first connecting member 50 is inserted. On the other hand, the fixing means 16 of the first connecting member 50 is provided with an internal thread 58 in the cylinder of the area where the core member 44 is inserted.

[0205] The fixing means 16 of the first connecting structure 50 is threadedly connected to the fixing means 16 of the core member 44. By rotating the first connecting structure 50, it can be moved in the length direction of the operating rod 12 and can be stopped at a position suitable for pressing the second connecting structure 80 by the first connecting structure 50.

[0206] In this embodiment, the main body 20 of the operating rod 12 is a rod with a roughly circular cross-section, the first connecting part 40 and the second connecting part 42 of the core component 44 are rods with a roughly circular cross-section, the first connecting member 50 is an annular body with a roughly circular cross-section, and the second connecting member 80 is an annular body with a roughly circular cross-section.

[0207] Furthermore, the main body 20, core component 44, first connecting structural member 50, and second connecting structural member 80 of these operating rods 12 are arranged concentrically with a center line extending in the axial direction of the rod body.

[0208] The first connecting member 50 is disposed around the second connecting portion 42 of the core member 44, and the second connecting member 80 is disposed around the front end side of the core member 44. The end edge of the front end side of the first connecting member 50 and the end edge of the second connecting member 80 are formed opposite to each other.

[0209] Next, regarding the operation method, the following description assumes that the insulating operating rod 12, which has the connection structure 10 according to the embodiment, is used to operate the front end tool 14 connected to the front end of the overhead power distribution line in order to form a bypass circuit for the overhead power distribution line.

[0210] First, such as Figure 1 and 2 As shown, in order to assemble the front-end tool 14 for indirect live wire construction to the front end of the insulating operating rod 12, the operator connects the connecting part 24 (operating rod side) of the insulating operating rod 12 and the connecting part 32 (front-end tool side) of the front-end tool 14, which constitutes the connecting structure 10.

[0211] Specifically, the axis of the connecting part 24 on the operating rod 12 side is aligned with the axis of the connecting part 32 on the front tool 14 side, and the first fixing protrusion (pin) 60 is aligned with the first groove 90A of the first fixing groove 90.

[0212] Next, the operating rod 12 is moved toward the front tool 14 side, and the first fixing protrusion (pin) 60 is inserted into the second groove 90B of the first fixing groove 90. After reaching the groove wall on the front tool 14 side of the second groove 90B, the operating rod 12 is rotated in the circumferential direction, so that the first fixing protrusion (pin) 60 moves along the groove of the second groove 90B toward the third groove 90C.

[0213] When the connecting structure 10 reaches the opening of the third groove 90C, that is, when it reaches the end of the second groove 90B, the operating rod 12 is pulled back from the front tool 14 side to the hand side, and the first fixing protrusion (pin) 60 is embedded into the third groove 90C.

[0214] Therefore, by rotating the first connecting member 50, the first connecting member 50 moves along the length of the operating rod 12 due to the action of the external thread 48 of the first connecting member 50 and the internal thread 58 of the core member 44, so that the first connecting member 50 presses the second connecting member 80, and the connecting part 24 (operating rod side) of the operating rod 12 and the connecting part 32 (front tool side) of the front tool 14 are firmly connected.

[0215] Next, regarding the release of the locking of the connecting part 24 (operating rod side) of the operating rod body 20 and the connecting part 32 (front tool side) of the tool part (front tool part) 30 in the connecting structure 10, it is mainly based on Figure 4 To explain, rotate the first connecting member 50 to disengage the external thread 48 from the internal thread 58 and move it toward the hand. Then, move the connecting part 24 (on the operating rod side) of the operating rod body 20 toward the front end (by pressing the first connecting member 50 toward the hand using the second connecting member 80), causing the first fixing protrusion (pin) 60 constituting the fixing means 16 to disengage from the third groove 90C. Rotate the operating rod 12 to move the first fixing protrusion (pin) 60 along the second groove 90B. When it is located in the first groove 90A of the first fixing groove 90, move the operating rod 12 toward the hand to disengage the first fixing protrusion (pin) 60 from the first fixing groove 90, thereby separating the connecting part 24 (on the operating rod side) of the operating rod 12 from the connecting part 32 (on the front tool side) of the front tool 14.

[0216] (Second Implementation)

[0217] Next, regarding the connecting structure structure as a variation of the first embodiment, namely the second embodiment, it is mainly based on Figures 10 to 1980. Figure 15 Let me explain.

[0218] Furthermore, in the description of the connecting structure in the second embodiment, which is a variation of the first embodiment, regarding the connection with... Figures 1 to 9 The common constituent elements of the connecting structure 10 shown in the figure, which is the first embodiment, are labeled with the same reference numerals, and the description of the common constituent elements is omitted.

[0219] Hereinafter, we will focus on the characteristic constituent elements of the connecting structure, which is a modified example of the first embodiment.

[0220] The connecting structure 10, as a second embodiment of this utility model, is a connecting structure that connects the operating rod 12 constituting the rod body and the connecting part of the front end tool 14 constituting the connected part connected to the operating rod 12.

[0221] The operating rod 12 has an elongated cylindrical operating rod body 20, a gripping part 22 attached to the rear end of the operating rod body 20, i.e. the front side of the hand, and a connecting part 24 (operating rod side) formed on the front end side of the operating rod body 20, i.e. the area on the side to which the front tool 14 is mounted.

[0222] The front-end tools 14 for indirect live wire construction include, for example, a stripping machine, pliers, and clamping parts for stripping the insulation film off overhead distribution wires in the live wire state.

[0223] The front-end tool 14 has a tool part 30 that is in direct contact with wires, etc., and a connecting part 32 (on the front-end tool side) formed in the area that connects the tool part 30 to the operating rod 12, constituting the connected part.

[0251] The rebound member 70 constituting the suppression means 18 can be configured to apply force to the first connecting member 50 towards the second connecting member 80 when the front tool 14 is installed onto the operating rod 12.

[0252] The connecting part 24 (on the control stick side) has a core member 44 fixed at the center of the front end of the control stick body 20, and a first connecting member 50 is arranged around the core member 44.

[0253] Furthermore, the connecting part 24 (on the operating rod side) is provided with a restraining means 18 around the hand side of the core member 44, which is formed to rebound from the hand side of the operating rod 12 toward the front tool 14 side and is composed of a rebounding member 70 such as a coil spring.

The second connecting part 42 is provided with the first fixing protrusion (pin) 60 and is configured to allow the second connecting member 80 constituting the connecting part 32 (on the front tool side) to be inserted around it.

[0255] The first connecting structural member 50 is annular and nested around the generally cylindrical core member 44, configured to be twisted along the length of the core member 44 and the operating rod body 20. It is configured to be bounced towards the front end by a rebound member 70 (not shown) inserted between the hand side of the first connecting structural member 50 and the front end side of the operating rod body 20.

[0256] The first fixed protrusion (pin) 60 is formed in the center of the connecting portion 24 (on the operating rod side) and extends radially.

[0257] The first fixed protrusion (pin) 60 is configured to be able to move axially on the operating rod 12 relative to the front end tool 14 as the operating rod 12 moves, and is configured to be able to rotate circumferentially on the operating rod 12.

[0258] The connecting part 32 (on the front tool side) constitutes the mounting part for mounting to the operating rod 12, and is provided with a second connecting member 80 that is configured to connect the connecting part 24 on the operating rod 12 side.

[0259] The second connecting member 80 has a first fixing groove 90 formed in the region on the side connected to the operating rod 12, which stops the first fixing protrusion (pin) 60 disposed on the connecting part 24 on the side of the operating rod 12. The first fixing groove 90 is for the first fixing protrusion (pin) 60 to be inserted, thus forming a fixing means 16 for fixing the first fixing protrusion (pin) 60 when the connecting part 24 (on the operating rod side) and the connecting part 32 (on the front tool side) are connected.

[0260] The first fixing groove 90 has a first groove portion 90A that opens to the side of the operating rod 12, a second groove portion 90B that opens to the first groove portion 90A, and a third groove portion 90C that opens to the second groove portion 90B. The first groove portion 90A extends in the length direction, the second groove portion 90B extends in the circumferential direction, and the third groove portion 90C extends in the length direction and becomes a dead end.

[0261] The first fixing groove 90 is formed in the shape of an L when viewed from above, and is configured such that when the front tool 14 is installed onto the operating rod 12, the first fixing protrusion (pin) 60 stops in the third groove 90C and does not move.

[0262] The first fixing groove 90 has a depth in which the head of the first fixing protrusion (pin) 60 protrudes slightly and a width in which the shaft portion of the first fixing protrusion (pin) 60 can move.

[0263] Based on the above configuration, the second connecting member 80, at the bottom of the third groove 90C, uses the force applied by the rebound member 70 and the second rebound member 76 to press the fixing means 16 (first fixing protrusion (pin) 60) that is radially protruding and fixed in the second connecting part 42 of the first connecting part 40 connected to the operating rod body 20 toward the front end side (the mounting part), thereby engaging the third groove 90C and the fixing means 16 (first fixing protrusion (pin) 60), so that the second connecting member 80 will not move in the locking release direction.

[0264] The first fixing protrusion (pin) 60 is provided to protrude radially from the first connecting structural member 50.

[0265] The first fixing groove 90 has a depth in which the head of the embedded first fixing protrusion (pin) 60 protrudes slightly, and a width in which the shaft portion of the embedded first fixing protrusion (pin) 60 can move.

[0266] The second connecting member 80 constitutes a mounting part that is installed to the (front end) tool part 30 and connected to the operating rod 12, and includes a first connecting part 82, which is installed to the (front end) tool part 30 as a front end tool mounting part, and a second connecting part 84 that is thicker than the first connecting part 82, which is the front end tool mounting part.

[0267] The first connecting part 82 is fitted into the mounting part of the (front end) tool part 30 and is fixed to the (front end) tool part 30 by a suitable fastener (e.g., a pin).

[0268] The second connecting part 84 constitutes a hollow core component mounting part, and has a rod-side connecting part mounting hole 94 for the core component 44 to be inserted.

[0269] The second connecting part 84 has a columnar core component mounting part 96 provided in the mounting hole 94 of the connecting part on the rod body side.

[0270] The columnar core component mounting portion 96 is inserted into the annular hollow portion 46 between the second connecting portion 42 of the core component 44 and the (second) operating rod mounting component 28, and is connected to the front end side of the (second) operating rod mounting component 28.

[0271] (Second) The operating rod mounting component 28 and the columnar core component mounting part 96 are arranged in a row and are installed at the second connecting part 42 of the core component 44.

[0272] The columnar core component mounting portion 96 is configured to abut against the hand side of the second connecting member 80. A second rebound member 76, such as a helical spring, is provided in the second hollow portion 46b between the end of the columnar core component mounting portion 96 at the hand side and the boundary wall of the first hollow portion 46a of the hollow portion 46, which is formed to rebound the columnar core component mounting portion 96 toward the hand side or the front end.

[0273] The second rebound component 76 can also be omitted.

[0274] As shown in Figure 10, the columnar core component mounting part 96 is embedded in the hollow part 46 of the second connecting part 42 and fixed to the (second) operating rod mounting part 28 by means of the anti-loosening screw 28a.

[0275] Furthermore, the columnar core component mounting portion 96 is provided with a third rebound member 98, which is formed to rebound from the front end tool 14 side toward the operating rod 12 side, in a recessed portion at its front end side in the rod-side connection mounting hole 94 of the second connecting structure 80.

[0276] The third rebound member 98 can be fixed to the front end of the columnar core member mounting part 96, or it can be inserted and fixed to the recess 32a formed in the center of the connecting part 32 (on the front tool side).

[0277] When locked, the third rebound member 98 constituting the restraint means 18 presses the second connecting member 80 toward the front end.

[0278] (Type 2)

[0279] The first connecting member 50 is disposed on the operating rod 12 in such a way that it can move axially. It is configured such that when the front end tool 14 is installed on the operating rod 12, it is fixed to the area of ​​the second connecting member 80 on the operating rod 12 side to control the movement of the second connecting member 80, so as to prevent the connecting part 24 (on the operating rod side) from disengaging from the first fixing groove 90 of the second connecting member 80.

[0280] The first connecting structural member 50 has a fixing means 16 for controlling the movement of the second connecting structural member 80.

[0281] The fixing means 16 of the core member 44 is composed of an external threaded portion 48 provided on the outer periphery of the area where the first connecting member 50 is inserted. On the other hand, the fixing means 16 of the first connecting member 50 is composed of an internal threaded portion 58 provided in the cylinder in the area where the core member 44 is inserted.

[0282] The internal thread 58 of the fixing means 16 constituting the first connecting member 50 is threadedly connected to the external thread 48 of the fixing means 16 constituting the core member 44. By rotating the first connecting member 50, it can be moved in the length direction of the operating rod 12 and can be stopped at a position suitable for pressing the second connecting member 80 by the first connecting member 50.

[0283] In this embodiment, the main body 20 of the operating rod 12 is a rod with a roughly circular cross-section, the first connecting part 40 and the second connecting part 42 of the core component 44 are rods with a roughly circular cross-section, the first connecting member 50 is an annular body with a roughly circular cross-section, and the second connecting member 80 is an annular body with a roughly circular cross-section.

[0284] Furthermore, the main body 20, core component 44, first connecting structural member 50, and second connecting structural member 80 of these operating rods 12 are arranged concentrically with a center line extending in the axial direction of the rod body.

[0285] The first connecting member 50 is disposed around the second connecting portion 42 of the core member 44, and the second connecting member 80 is disposed around the front end side of the core member 44. The end edge of the front end side of the first connecting member 50 and the end edge of the second connecting member 80 are formed opposite to each other.

[0286] Next, regarding the operation method, the following description assumes that the insulating operating rod 12, which has the connection structure 10 according to the embodiment, is used to operate the front end tool 14 connected to the front end of the overhead power distribution line in order to form a bypass circuit for the overhead power distribution line.

[0287] First, as shown in Figures 10 and 11, in order to assemble the front-end tool 14 for indirect live wire construction to the front end of the insulating operating rod 12, the operator connects the connecting part 24 (operating rod side) of the insulating operating rod 12 and the connecting part 32 (front-end tool side) of the front-end tool 14, which constitutes the connecting structure 10.

[0288] Specifically, the axis of the connecting part 24 on the operating rod 12 side (operating rod side) and the axis of the connecting part 32 on the front tool 14 side (front tool side) are aligned, and the first fixing protrusion (pin) 60 is aligned with the first groove 90A of the first fixing groove 90.

[0289] Next, the operating rod 12 is moved toward the front tool 14 side, and the first fixing protrusion (pin) 60 is inserted into the second groove 90B of the first fixing groove 90. After reaching the groove wall on the front tool 14 side of the second groove 90B, the operating rod 12 is rotated in the circumferential direction, so that the first fixing protrusion (pin) 60 moves along the groove of the second groove 90B toward the third groove 90C.

[0290] When the connecting structure 10 reaches the opening of the third groove 90C, that is, when it reaches the end of the second groove 90B, the operating rod 12 is pulled back from the front tool 14 side to the hand side, and the first fixing protrusion (pin) 60 is embedded into the third groove 90C.

[0291] Therefore, by rotating the first connecting member 50, the first connecting member 50 moves along the length of the operating rod 12 due to the action of the external thread 48 of the first connecting member 50 and the internal thread 58 of the core member 44, so that the first connecting member 50 presses the second connecting member 80, and the connecting part 24 (operating rod side) of the operating rod 12 and the connecting part 32 (front tool side) of the front tool 14 are firmly connected.

[0292] Next, regarding the release of the locking of the connecting part 24 (operating rod side) of the operating rod body 20 and the connecting part 32 (front tool side) of the tool part (front tool part) 30 in the connecting structure 10, it is mainly based on Figure 11 To explain, rotate the first connecting member 50 to disengage the external thread 48 from the internal thread 58 and move it toward the hand. Then, move the connecting part 24 (on the operating rod side) of the operating rod body 20 toward the front end (by pressing the first connecting member 50 toward the hand using the second connecting member 80), causing the first fixing protrusion (pin) 60 constituting the fixing means 16 to disengage from the third groove 90C. Rotate the operating rod 12 to move the first fixing protrusion (pin) 60 along the second groove 90B. When it is located in the first groove 90A of the first fixing groove 90, move the operating rod 12 toward the hand to disengage the first fixing protrusion (pin) 60 from the first fixing groove 90, thereby separating the connecting part 24 (on the operating rod side) of the operating rod 12 from the connecting part 32 (on the front tool side) of the front tool 14.

[0293] (Third Implementation)

[0294] Next, regarding the connecting structure structure, which is a variation of the first embodiment, namely the third embodiment, it is mainly based on Figures 16 to 17. Figure 21 Let me explain.

[0353] The first connecting member 50 is configured to cover the first fixing protrusion (pin) 60 constituting the fixing means 16 when the front end tool 14 is installed onto the operating rod 12, and is configured to contain the second connecting part 84 of the second connecting member 80 and the third connecting member 52 in its hollow portion.

[0354] The second connecting portion 84 of the first connecting member 50 and the second connecting member 80 is configured to be axially screwed by the external thread portion 88 and the internal thread portion 58 that constitute the fixing means 16 when the first connecting member 50 is rotated.

[0355] In this embodiment, the first connecting member 50 has an internal thread 58 formed on the inner side of the area where it overlaps with the second connecting portion 84 of the second connecting member 80, and the second connecting member 80 has an external thread 88 formed on the outer side of the area of ​​the second connecting portion 84 covered by the first connecting member 50.

[0356] In this embodiment, the main body 20 of the operating rod 12 is a rod with a roughly circular cross-section, the first connecting part 40 and the second connecting part 42 of the core component 44 are rods with a roughly circular cross-section, the first connecting member 50 is an annular body with a roughly circular cross-section, the third connecting member 52 is an annular body with a roughly circular cross-section, and the second connecting member 80 is an annular body with a roughly circular cross-section.

[0357] Furthermore, the main body 20, core component 44, first connecting structural member 50, third connecting structural member 52, and second connecting structural member 80 of these operating rods 12 are arranged concentrically with a center line extending in the axial direction of the rod body.

[0358] The third connecting structural member 52 is disposed around the second connecting portion 42 of the core member 44, the first connecting structural member 50 is disposed around the second connecting portion 84 of the third connecting structural member 52 and the second connecting structural member 80, the second connecting structural member 80 is disposed around the front end side of the core member 44, and the end edge of the front end side of the third connecting structural member 52 and the end edge of the second connecting structural member 80 are configured to face each other.

[0359] Next, regarding the operation method, the following description assumes that the insulating operating rod 12, which has the connection structure 10 according to the embodiment, is used to operate the front end tool 14 connected to the front end of the overhead power distribution line in order to form a bypass circuit for the overhead power distribution line.

[0360] First, as shown in Figure 16 and Figure 17 As shown, in order to assemble the front-end tool 14 for indirect live wire construction to the front end of the insulating operating rod 12, the operator connects the connecting part 24 (operating rod side) of the insulating operating rod 12 and the connecting part 32 (front-end tool side) of the front-end tool 14, which constitutes the connecting structure 10.

[0361] Specifically, the axis of the connecting part 24 on the operating rod 12 side (operating rod side) and the axis of the connecting part 32 on the front tool 14 side (front tool side) are aligned, and the first fixing protrusion (pin) 60 is aligned with the first groove 90A of the first fixing groove 90.

[0362] Next, the operating rod 12 is moved toward the front tool 14 side, and the first fixing protrusion (pin) 60 is inserted into the second groove 90B of the first fixing groove 90. After reaching the groove wall on the front tool 14 side of the second groove 90B, the operating rod 12 is rotated in the circumferential direction, so that the first fixing protrusion (pin) 60 moves along the groove of the second groove 90B toward the third groove 90C.

[0363] When the connecting structure 10 reaches the opening of the third groove 90C, that is, when it reaches the end of the second groove 90B, the operating rod 12 is pulled back from the front tool 14 side to the hand side, and the first fixing protrusion (pin) 60 is embedded into the third groove 90C.

[0364] Therefore, by rotating the first connecting member 50, the first connecting member 50 moves along the length of the operating rod 12 due to the action of the internal thread 58 of the first connecting member 50 and the external thread 88 of the second connecting member 80, so that the first connecting member 50 is moved to the position where the second connecting member 80 is pressed by the third connecting member 52, so that the connecting part 24 of the operating rod 12 (operating rod side) and the connecting part 32 of the front tool 14 (front tool side) are firmly connected.

[0365] Next, regarding the release of the locking of the connecting part 24 (operating rod side) of the operating rod body 20 and the connecting part 32 (front tool side) of the tool part (front tool part) 30 in the connecting structure 10, it is mainly based on Figure 17Let me explain. At this time, rotating the first connecting member 50 moves it toward the hand side, causing the connecting part 24 (on the operating rod side) of the operating rod body 20 to move toward the front end side, thereby disengaging the first fixing protrusion (pin) 60 constituting the fixing means 16 from the third groove 90C. Rotating the operating rod 12 causes the first fixing protrusion (pin) 60 to move along the second groove 90B. When it is located in the first fixing groove 90, moving the operating rod 12 toward the hand side causes the first fixing protrusion (pin) 60 to disengage from the first fixing groove 90, thereby enabling the separation of the connecting part 24 (on the operating rod side) of the operating rod 12 and the connecting part 32 (on the front tool side) of the front tool 14.

[0424] The second connecting part 84 constitutes a hollow core component mounting part, and has a rod-side connecting part mounting hole 94 for the core component 44 to be inserted.

[0425] Furthermore, a first fixing groove 90 is formed at the opening edge of the mounting hole 94 on the side of the rod body.

[0426] The first connecting member 50 is disposed on the side of the operating rod 12 in such a way that it can move axially on the operating rod 12. It is configured to control the movement of the second connecting member 80 by fixing it to the area on the operating rod 12 side of the second connecting member 80 when the front tool 14 is installed on the operating rod 12, so as to prevent the connecting part 24 (on the operating rod side) from disengaging from the first fixing groove 90 of the second connecting member 80.

[0427] Furthermore, the first connecting member 50 has a fixing means 16 for fixing the first connecting member 50 to the second connecting portion 42 of the first connecting portion 40 in order to control the movement of the second connecting member 80. The fixing means 16 for fixing the first connecting member 50 to the second connecting portion 42 of the first connecting portion 40 is composed of the second fixing protrusion (plunger) 62.

[0428] In this embodiment, the main body 20 of the operating rod 12 is a rod with a roughly circular cross-section, the first connecting part 40 and the second connecting part 42 of the core component 44 are rods with a roughly circular cross-section, the first connecting member 50 is an annular body with a roughly circular cross-section, and the second connecting member 80 is an annular body with a roughly circular cross-section.

[0429] Furthermore, the main body 20, core component 44, first connecting structural member 50, and second connecting structural member 80 of these operating rods 12 are arranged concentrically with a center line extending in the axial direction of the rod body.

[0430] The first connecting member 50 is disposed around the second connecting portion 42 of the core member 44, and the second connecting member 80 is disposed around the front end side of the core member 44. The end edge of the front end side of the first connecting member 50 and the end edge of the second connecting member 80 are formed opposite to each other.

[0431] Next, regarding the operation method, the following description assumes that the insulating operating rod 12, which has the connection structure 10 according to the fourth embodiment, is used to operate the front end tool 14 connected to the front end of the overhead power distribution line in order to form a bypass circuit for the overhead power distribution line.

[0432] First, such as Figure 32 As shown, in order to assemble the front-end tool 14 for indirect fire line construction to the front end of the operating rod 12, the operator connects the connecting part 24 (operating rod side) of the operating rod 12 and the connecting part 32 (front-end tool side) of the front-end tool 14, which constitutes the connecting structure 10.

[0433] Specifically, the axis of the connecting part 24 on the side of the operating rod 12 is aligned with the axis of the connecting part 32 on the side of the front tool 14, and the first fixing protrusion (pin) 60 is aligned with the first groove 90A of the first fixing groove 90.

[0434] Next, the operating rod 12 is moved toward the front tool 14 side, and the first fixing protrusion (pin) 60 is inserted into the second groove 90B of the first fixing groove 90. After reaching the groove wall on the front tool 14 side of the second groove 90B, the operating rod 12 is rotated in the circumferential direction, so that the first fixing protrusion (pin) 60 moves along the groove of the second groove 90B toward the third groove 90C.

[0435] When the connecting structure 10 reaches the opening of the third groove 90C, that is, when it reaches the end of the second groove 90B, the operating rod 12 is pulled back from the front tool 14 side to the hand side, and the first fixing protrusion (pin) 60 is embedded into the third groove 90C.

[0436] When fixing the first connecting member 50 to the second connecting part 42, such as Figure 32 As shown in (B), the first connecting member 50 moves along the length of the operating rod 12 due to the action of the second fixing protrusion (plunger) 62 of the first connecting member 50 and the second fixing groove 92 of the core member 44. The first connecting member 50 is moved to a position where it presses the second connecting member 80, so that the first connecting member 50 and the second connecting part 42 are connected, so that the connecting part 24 (operating rod side) of the operating rod 12 and the connecting part 32 (front tool side) of the front tool 14 are firmly connected.

[0437] In this embodiment, the axis of the core member 44 is aligned with the axis of the second connecting part 42, and the second fixing protrusion (plunger) 62 is aligned with the first groove 92A of the second fixing groove 92.

[0438] Next, the first connecting member 50 is moved toward the front tool 14 side, and the second fixing protrusion (plunger) 62 is inserted into the second groove 92B of the second fixing groove 92. After reaching the groove wall on the front tool 14 side of the second fixing groove 92, the first connecting member 50 is rotated in the circumferential direction, so that the second fixing protrusion (plunger) 62 moves along the groove of the second groove 92B toward the third groove 92C.

[0439] When the second fixed protrusion (plunger) 62 reaches the opening of the third groove 92C, that is, when it reaches the end of the second groove 92B, the second fixed protrusion (plunger) 62 is embedded into the third groove 92C.

[0440] In this way, by rotating the first connecting member 50, the first connecting member 50 is moved to the position of pressing the second connecting member 80 due to the action of the second fixing protrusion (plunger) 62 of the first connecting member 50 and the second fixing groove 92 of the second connecting part 42, so that the first connecting member 50 is connected to the second connecting part 42 of the core member 44.

[0441] Regarding the unlocking of the connecting part 24 (operating rod side) of the operating rod body 20 and the connecting part 32 (front tool side) of the tool part (front tool part) in the connecting structure 10, it is mainly based on Figure 33 The following explanation is provided. The first connecting member 50 is rotated to move it to the position of the second groove 92B and temporarily fixed. Then, the connecting portion 24 (operating rod side) of the operating rod body 20 is moved towards the front end. As the first connecting member 50 moves, the second connecting member 80 is pressed towards the hand, causing the first fixing protrusion (pin) 60 constituting the fixing means 16 to disengage from the third groove 90C. The operating rod 12 is rotated to move the first fixing protrusion (pin) 60 along the second groove 90B. When it is located in the first fixing groove 90, the operating rod 12 is moved towards the hand, causing the first fixing protrusion (pin) 60 to disengage from the first fixing groove 90. This allows the connecting portion 24 (operating rod side) of the operating rod 12 and the connecting portion 32 (front tool side) of the front tool 14 to be separated.

[0442] (Modifications of the first to third embodiments)

[0443] The following is based on Figures 36 to 38 The following describes variations of the first to third embodiments.

[0444] In this modified example, the connecting structure 10 is formed near the hand side of the rod, rather than near the front end tool 14 with the connected part.

[0445] The modified connection structure 10 is a structure that connects the hand-side rod and the front-end rod of the rod that is divided into two parts, forming a first operating rod 12A connected to the front-end tool 14 constituting the operating rod 12 and a second operating rod 12B constituting the hand-side operating rod 12.

[0446] The first operating rod 12A constitutes a connecting part, with a connected part formed on its front end side, and the second operating rod 12B constitutes a rod body, with a connecting part formed on its rear end.

[0447] In a variation of the first embodiment, the operating rod 12 includes an elongated cylindrical operating rod body 20 constituting a first operating rod body 12A, and a gripping portion 22 attached to the rear end of the operating rod body 20, i.e., the front side of the hand, constituting a second operating rod body 12B.

[0448] The main body 20 of the operating rod is equipped with a front tool 14 on its front end side and has a connecting part 24 (on the operating rod side) that constitutes the connected part in the region on its rear end side.

[0449] As described above, although the embodiments of this utility model have been disclosed in the above description, this utility model is not limited thereto.

[0450] That is, without departing from the technical concept and purpose of this utility model, various changes can be made to the above-described embodiments regarding the mechanism, shape, material, quantity, position or configuration, etc., and these are all included in this utility model.

[0451] In the embodiment described above, the connecting portion 24 on the operating rod 12 side of the rod body and the connecting portion 32 on the connected portion side are arranged and combined concentrically with a center line extending in the axial direction of the rod body. A protrusion is formed in one connecting portion 24 and a recess is formed in the other connecting portion 32. However, a rod-side connecting portion mounting hole 94 constituting a recess may be formed in the connecting portion 24 (on the operating rod side), and a core member 44 constituting a protrusion may be formed in the connecting portion 32 (on the front tool side).
