[0064] The nut portion (510) contacts the reaction portion (331) of the fixed clamp portion (300), and by using the reaction portion (331) as a support to move the nut portion (420) back and forth according to the fastening direction, the variable clamp portion (400) and the fixed clamp portion (300) can grip the wire (20).

[0065] The nut connection part (520) has a predetermined space (S), and this space (S) represents a type of safety space that enables forward and backward movement according to the screw fastening of the tip of the nut part (510).

[0066] The ring portion (530) is in the shape of a ring, and by inserting an indirect live wire insulating stick into the ring portion and rotating the operating stick ring (500), the nut portion (510) is screwed onto the bolt portion (420), so that the nut portion (420) can be moved back and forth in the direction of connection using the reaction portion (331) as a support.

[0067] This operation allows the wire (20) placed inside to be grasped by bringing the variable grab part (430) of the variable gripper (400) close to the fixed grab part (320) of the fixed gripper (300).

[0068] FIG. 7 is a perspective view of another example of a fixed clamp portion of a high-voltage danger sign device capable of indirect live-line work according to the present invention.

[0069] The fixed clamp part (600) shown in Fig. 7 may have the same structure and shape as the fixed clamp part (300) shown in Fig. 4, except that a contact part (632) of a rubber material component is further formed on the front end surface of the reaction part (631).

[0070] When the fixed clamp part (600) and the variable clamp part (400) fix the wire (20) by the operating stick ring (500), the contact part (632) is screw-coupled with the nut part (510) and the bolt part (420), and the bolt part (420) is moved back and forth using the reaction part (631) as a support, and at this time, the contact force between the nut part (510) and the reaction part (631) is increased.

[0071] Additionally, the contact portion (632) can perform the function of preventing arbitrary loosening of the nut portion (510) when tightened while the nut portion (510) and the reaction portion (631) are in contact.

[0072] The base portion (310, 610), fastening hole (311, 611), fixed grab portion (320, 620), landing portion (330, 630), and reaction portion (331, 631) of FIGS. 4 and 7 can each have the same shape and structure.

[0073] FIG. 8 is a diagram of the connection process of a high-voltage hazard sign device capable of indirect live-line work according to the present invention.

[0074] As illustrated in FIG. 8, the high-voltage hazard sign device capable of indirect live-line operation according to the present invention can mount a hazard sign on a wire in the following order.

[0075] First, referring to (A), the variable clamp part (400), the fixed clamp part (300), and the operating stick ring (500) are arranged in the order shown.

[0076] Afterwards, as in (B) and (C), the bolt portion (420) of the variable clamp portion (400) is positioned on the landing portion (330) of the fixed clamp portion (300) and passed through the reaction portion (331), and the nut portion (510) is screw-coupled to the bolt portion (420) that has passed through.

[0077] Assembly configurations in states such as (A), (B), and (C) can be performed in advance.

[0078] Afterward, as in (D), the sign (100) is mounted on the fastening rod (200) and the fastening rod (200) is inserted into the fastening hole (311) of the fixing clamp part (300). Then, while rotating the ring (530) using an indirect live wire insulating stick, the nut part (510) is retracted while the nut part (510) is screw-coupled to the bolt part (420).

[0079] The process of inserting the sign (100) can also be performed in advance.

[0080] At this time, the nut part (510) comes into contact with the reaction part (331), and by using the reaction part (331) as a support and moving the bolt part (420) backward according to the screw connection, the variable grab part (430) of the variable gripper part (400) is brought into close contact with the fixed grab part (320) of the fixed gripper part (300), and the wire (20) placed between the fixed grab part (320) and the variable grab part (430) can be firmly gripped while being completely in close contact.

[0081] This structure and fastening operation can be applied to the indirect live-line method using an insulating stick for indirect live-lines, and since the gap can be adjusted by the forward and backward movement of the variable grab part (430) based on the fixed grab part (320), a danger sign attachment device that can be applied to almost all distribution lines regardless of the wire thickness can be provided.

[0082] Although the present invention, as described in detail above, has been explained based on limited embodiments and drawings, the present invention is not limited thereto, and various modifications and variations are possible within the scope of the technical spirit of the present invention and the equivalent scope of the patent claims by those skilled in the art to which the present invention belongs.

[0083] However, it is evident that such simple modifications and variations cannot fall outside the scope of the rights of the present invention. Explanation of the symbols
