The pedestal 22 is disposed between the side plates 21 so that both ends thereof are opposed to the inner surface of the side plate 21 and are fixed to the side plate 21 through fastening means (for example, screw bolts), and an upper surface of the pedestal 22. The wire support portion (22a) for supporting the underground distribution line (L) is installed.

The rail support part 23 is a member extending downward from the lower surface of the side plate 21, and is formed at regular intervals along the longitudinal direction of the side plate 21.

The rail 24 is a circular rod having a circular cross section, and extends in the longitudinal direction of the side plate 21 from the lower end of the rail support 23 so that the transfer block 30 can be moved along the longitudinal direction of the side plate 21. It serves as a guide.

1 to 3, the transfer block 30 has a rectangular parallelepiped shape as a whole, and a first shaft hole 31 is formed on the side surface (based on FIG. 3) to be rotatably and movable on the rail 24. On the outer circumferential surface on which the first shaft hole 31 is formed, a cutout portion 32 communicating with the first shaft hole 31 is integrally formed so as to pass through the rail support part 23, and the front and rear surfaces thereof (see FIG. 3). The second shaft hole 33 is formed to be orthogonal to the first shaft hole 31 and to which the wire laying mechanism 50 is movable.

1 to 3, the sweep cloth 40 is a conventional nonwoven fabric, is installed around the first shaft hole 31 of the transfer block 30, and moves by the transfer block 30. It adsorbs and removes foreign substances adhering to the surface of).

Particularly, when the swept cloth 40 is moved with the transfer block 30 in the state of absorbing the lubricating oil or the like, the lubricating oil discharged from the swept cloth 40 during the moving process is naturally formed on the surface of the rail 24. As applied, the friction between the transfer block 30 and the rails 24 can be reduced, thereby minimizing noise generation.

1 to 3, the wire laying mechanism 50 is a member of an insulating material, the worker is to manually move the underground distribution line (L) installed to be installed on the transfer block (30) installed manually. It is a tool to use.

The wire laying mechanism 50 is formed on one end of the round bar 51 and the round bar 51 to be movably inserted into the second shaft hole 33 of the transfer block 30 to hang the underground distribution line (L). It is formed on the other end of the hook 52 and the round bar 51 is formed in the 'C' shape so that the worker is composed of a handle 53 for holding.
