ABSTRACT:
A coupling device comprises a retainer including a spring-loaded joint bar with a push rod perpendicular thereto, and an insertion including a solid body having a recess and a guide slope.
The retainer is attached to a stroboscope holder, while the insertion is attached to a bracket.
The insertion is easily and quickly connected with the retainer by inserting the solid body into the retainer.
By a force which the joint bar receives from the solid body, the joint bar is caused to slide against a force of a spring along a guide slope until the joint bar falls in a recess, and the joint bar is engaged with the recess.
On the other hand, the insertion is removed easily and quickly from the retainer merely by pushing the push rod until the engagement of the joint bar with the recess is released, and then pulling out the insertion from the retainer.
