Clips 7 are set on the horizontal bar 22 where the vertical bars 31 and 33 are connected to the bar 22 and both ends of the steel rod 6 are removably inserted between these clips and the vertical bars 31 and 33. Further, a spring 8 is connected to the pin 14 almost on the middle point between vertical bars 31 and 33 and its end 8' stretches out of the horizontal bar 22. The top end 8' is forcibly pushed down with a pusher to make the rod 6 removable from between the vertical bars 31 and 33 and the clips 7.
