Description

  The present invention relates to a tip tool for indirect hot wire that can be attached to the tip of an indirect hot wire tool.

  In indirect hot wire work, an indirect hot wire tool is used.For example, in order to hold a member such as a protective insulating sheet or a predetermined instrument, a grip portion is provided at a rod-shaped tip. A Yatco having an operation part for operating opening and closing of the gripping part is used at the other end (see Patent Document 1).

In addition, if you try to grip a pull line with a thin diameter with a Yatco, the pull line will come off from the grip part and it will be difficult to grip, so one of the grip parts will be formed in two and the tip of the other grip part will be closed Sometimes a quick formed so as to be inserted between two forks is used (see Patent Document 2).
As described above, in the indirect live line work, the indirect live line tool is properly used depending on the object to be grasped.

  However, as mentioned above, Yatco is unsuitable for gripping objects with a small diameter, and Quick can only be used for objects with a small diameter such as electric wires. There is a problem that workability is poor.

  Also, with Yatco or Quick, when trying to grip a large-diameter object such as a lever part of a pin insulator, the distance between the tips when the grip part is opened is shorter than the diameter of the insulator part, or the tip of the grip part Since the distance from the rotation axis to the rotation axis is shorter than the radius of the lever portion, the gripping portion cannot hold both side surfaces sandwiching the center of the lever portion.

For this reason, the gripping part may slip from the insulator part and the pin insulator may fall without stable gripping, and the pin insulator may be damaged due to the fall, or the material hit the dropped pin insulator may be damaged or dropped. There is also a risk that an operator may hit the pin insulator and get injured.
Therefore, the work must be changed from Yatco or Quick to another indirect hot-line work tool suitable for the work, which causes a problem that the work becomes complicated and the work time is extended.

  The present invention has been made in view of such circumstances, and an indirect live wire tip capable of working with one indirect live wire tip tool without using a plurality of types of indirect live wire tip tools. The main challenge is to provide tools.

In order to achieve the above object, an indirect live wire tip tool according to the present invention includes a first gripping piece that is attachable to a movable tip portion of an indirect live wire tool, and the indirect live wire tool. In the indirect live wire tip tool constituted by the second grip piece formed to be attachable to the fixed-side tip portion, the first grip piece and the second grip piece are the indirect live tool. A connecting portion formed so as to be attachable to the distal end portion, and a claw portion formed subsequent to the connecting portion, the claw portion having a rod-like portion formed extending in the distal end direction, The distance between the first gripping piece and the second gripping piece when the indirect live tool is opened is longer than the maximum width of the gripping object, and the length of the rod-shaped portion is the gripping target. at least a half length of the maximum width of the object, the second gripping piece, the bunch than the first gripping piece The first gripping piece is integrally formed with n (n is an integer of 2 or more) rod-like portions, and the second gripping piece has n + 1 rod-like portions. There are formed so as to be integrated, the gap is formed between the first gripping piece and the second rod-shaped portion adjacent the respective claw portions of the gripping piece, when closing the indirect hot tool, whereas The rod-shaped part of the other gripping piece is inserted into the gap of the gripping piece, and the gripping pieces intersect each other.

The distance between the first gripping piece and the second gripping piece when the indirect hot wire tool is opened is formed to be longer than the maximum width of the gripping object, and the claw portion is formed to extend in the tip direction. It has a rod-like portion, the length of the rod-like portion is at least half the maximum width of the grasped object, and there is a gap in at least one of the claw portions of the first or second grasping piece. When the indirect live tool is formed and the tip of the claw part of the other gripping piece is inserted into the gap and the gripping pieces intersect, the large diameter of the pin insulator like the lever part For objects, the gripping part can grip both side surfaces sandwiching the center of gravity of the object to be grasped, and for objects with a small diameter such as an underline, the object to be grasped is between the gap and the tip of the bar-shaped part. Since the object can be sandwiched and gripped, the object to be gripped can be grasped stably without using multiple indirect hot-line tools. It is possible to become.
The second gripping piece is formed wider in the gripping direction than the first gripping piece, and the gap is formed in the claw portion of the second gripping piece so that the fixed side of the indirect live wire tip tool is more Since the object to be grasped can be supported in a wide area, more stable grasping is possible.
By forming the gap between the rod-shaped portions, it is possible to reduce the weight of the indirect live wire tip tool, and to reduce the fatigue of the operator during the work.
The gap is formed in the claw portions of the first gripping piece and the second gripping piece, and the claw portion of the second gripping piece is formed with at least two gaps so that at least the first gripping piece is formed. It has two bar-shaped parts on the claw part of the piece and three bar-shaped parts on the claw part of the second gripping piece, and a wider one having a large diameter and weight like a lever part of the pin insulator. Since it becomes possible to hold by area, it becomes possible to hold stably.

Two rod-shaped portions may be integrally formed on the first grip piece, and three rod-shaped portions may be integrally formed on the second grip piece.

The rod-shaped portion is curved inward in the gripping direction so as to follow the side surface of the cylindrical gripping object when the indirect live tool is opened to the maximum, and the length of the rod-shaped part is the length of the gripping object. It may be formed longer than the radius.
Since the rod-shaped portion is formed to be curved inward in the gripping direction and can be gripped along the side surface of the gripping target formed in a cylindrical shape, it can be stably gripped. It becomes possible to prevent an object from falling.

  As described above, according to the indirect live tool tip of the present invention, the distance between the first gripping piece and the second gripping piece when the indirect live tool is opened is the maximum width of the gripping object. The claw portion has a rod-like portion formed extending in the distal direction, and the length of the rod-like portion is at least half the maximum width of the grasped object, When a gap is formed in at least one of the claw portions of the first or second gripping piece and the indirect live tool is closed, the tip of the claw portion of the other gripping piece is inserted into the gap, and both As the gripping piece intersects, the gripping part can grip both sides of the center of gravity of the object to be gripped, such as the lever part of the pin insulator, For small diameters, it can be gripped by inserting the tip of the rod-shaped part into the gap and sandwiching the object to be gripped. Kill Therefore, it is possible to grasp stably grasped object without using a plurality of indirect hot tool.

  This eliminates the need to prepare both Quick and Yatco tools or to use both Quick and Yatco properly, thus reducing work time and minimizing the necessary indirect hot-line tools. A wider working space can be secured.
