Mechanism for putting the head of a shaft into and out of the head of an outer sleeve comprised of an outer sleeve (1), a long hole (2) formed in the outer sleeve (1), and a clip (3) to be put into and out of the outer sleeve (1) through the long hole (2). A shaft (4) is inserted in the outer sleeve

Mechanism for putting the head of a shaft into and out of the head of an outer sleeve comprised of an outer sleeve (1), a long hole (2) formed in the outer sleeve (1), and a clip (3) to be put into and out of the outer sleeve (1) through the long hole (2). A shaft (4) is inserted in the outer sleeve (1), and a cam mechanism (8) cooperates with the clip (3) in a manner that causes the cam mechanism (8) to move forward and backward in an axial direction according to in and out movement of the clip (3). A spring (6) spring-biases the shaft (4) toward the cam mechanism.
