• a guide plate with a channel section comprising top, side, and bottom parts,
• a pair of slots in the top and bottom parts of said guide plate carrying said joint bar, said slots extending with their longer dimension parallel with the side part of said guide plate and engaging said joint bar near both its ends,
• a spring with one end fixed at an area outside an extremity of said slot in the top part of said guide plate and the other end attached to said joint bar, and
• a box with an opening therein, said guide plate being mounted with the side part of said guide plate plate fixed on a bottom thereof,
• said retainer being mounted on the stroboscope holder;
• and
• b. an insertion mounted on the bracket, said insertion comprising:
• a solid body having a recess adapted to receive said joint bar, a guide slope in front of, and in communication with, said recess, for guiding said joint bar into said recess, and a channel for permitting the passage of said push rod into the solid body as the joint bar moves into the recess, and
• whereby by inserting said insertion into said retainer, the bracket can be easily and quickly attached to the stroboscope holder in one motion, and by pushing said push rod and at the same time pulling out said insertion from said retainer, the bracket can be easily and quickly removed from the stroboscope holder.
