[Structure of the invention]

(Means for Solving the Problems) In order to solve the above problems, the present invention is configured as follows.

In other words, the present invention includes an outer cylinder having an open bottom surface with insertion holes formed in the top cover and both left and right sides, through which at least two cables are inserted, and a cable that is accommodated in the outer cylinder so as to be movable in the axial direction. a bottomed inner cylinder having insertion holes formed in the upper cover and both left and right sides corresponding to the insertion holes of the outer cylinder, through which at least two cables are inserted; a spring that constantly urges the inner cylinder toward the open bottom side of the outer cylinder; The parts of the reciprocating parts that pass through the upper lid insertion holes and are housed in the inner cylinder, and that reciprocate in this housing part are pulled out in a loop shape from the insertion holes on both left and right sides of the outer cylinder and the inner cylinder, respectively. A pair of left and right loop-shaped drawer outer ends are provided with cables for attaching a pair of locking tools that are locked to the lighting equipment so as to be movable in the longitudinal direction.

(Function) The pair of left and right loops of the cables pulled out from the pair of left and right side insertion holes of the inner cylinder and the outer cylinder are pulled out, and each locking tool at the outer end is attached to the locking receiver of the lighting fixture. The lighting fixture can be hung from the ceiling or the like at any desired height.

At this time, since the inner cylinder is urged toward the bottom opening side of the outer cylinder by the spring, each side insertion hole of the inner cylinder is pushed down relative to each side insertion hole of the outer cylinder.

For this reason, each insertion part of the cable pulled out from these side insertion holes to the left and right to the outside can be vertically moved by the lower edge of the opening of the side insertion hole of the outer cylinder and the upper edge of the opening of the side insertion hole of the inner cylinder. The inner tube and outer tube are strongly clamped and firmly fixed on the cable.

As a result, the lighting fixture can be suspended and held at any desired height.
