  However, since it is an acrylic plate, the acrylic plate hits the wall or the main body of the lighting fixture when it is attached to the tip of the support rod for operation, and the corners of the acrylic plate are easily broken or damaged. In addition, when the lighting fixture is installed on the wall, since the peripheral edge of the acrylic plate touches the wall, the pull string may not be guided well to the V-shaped guiding portion. For this reason, it is necessary to provide a notch recess for a small string guide and a string insertion hole at a different position on the periphery of the acrylic plate, or to separately provide a string insertion groove with a shallow depth, which complicates the configuration.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an inspection tool that can easily operate a pull ring of a drawstring even if a lighting fixture is installed on a wall and has a simple configuration and is not easily damaged.

The inspection tool of the present invention has an inspection switch, hangs a pull string for operating the check switch, and pulls the pull ring of a lighting fixture provided with a pull ring on the pull string , and It is an inspection tool supported by the upper end of the support rod in a vertical posture . The holding portion is formed by bending the wire so as to be folded back into a substantially U-shape, and forms a groove-like gap having a size that allows the pulling string to be inserted inside the folded portion but to be caught by the pulling ring. The invitation part extends at least one end of the wire forming the holding part and guides the drawstring to the holding part . The direction in which the draw string of the gap is inserted is the longitudinal direction of the support rod in the vertical posture .

In the above configuration, the invitation portion extends so as to separate both ends of the wire forming the holding portion, and protrudes outward in the longitudinal direction of the support rod from the upper end of the support rod in a vertical posture. A shaft is formed on one of the invitation portions. In the state where only the pulling wheel protrudes from the lower surface, the tip of the shaft is in contact with the lower surface of the lighting fixture, by sliding the shaft or rotating around the shaft, The other can be inserted into the pulling ring.

The said structure WHEREIN: The said axis | shaft has a structure which can push-operate the said push button of the type of lighting fixture which provided the push button in the lower surface.

  According to the inspection tool of the present invention, the pulling string is guided to the holding portion by the invitation portion formed by the wire, and the holding portion is lowered along the pulling ring by lowering the holding portion, and is caught on the pulling ring, and the pulling ring Can be pulled and operated. For this reason, the pulling wheel can be easily operated. In addition, since the invitation part is formed of a wire rod, the drawing string can be easily guided to the invitation part without complicating the configuration even when the lighting device is attached to the wall and the pull string is close to the wall. it can. Further, since the holding portion and the invitation portion are formed by bending the wire, the wall and the lighting fixture are not easily damaged by elasticity.

  Since a shaft protruding upward is formed at one end of the invitation portion, it can also be applied to a lever type inspection switch. For example, by sliding the shaft in a state where the tip of the shaft is in contact with the lower surface of the lighting fixture in which only the pulling wheel protrudes from the lower surface, or by rotating the other end of the invitation portion around the shaft, Since the other end of the invitation portion can be smoothly inserted into the pull ring, the pull ring can be easily operated.

  The shaft can be applied to different types of lighting fixtures when the push button of the lighting fixture having a push button on the lower surface can be operated.
