Spring-loaded locking bolt

A spring-loaded locking bolt comprising:

• a guide sleeve which is screwed into an associated bore in a machine or furniture part, the guide sleeve having a sleeve section,
• an actuator knob,
• an adjusting pin which is movably mounted axially in the guide sleeve and which is configured to be brought into at least two locking positions in the guide sleeve, and which can be adjusted from a locked position protruding axially out of the guide sleeve against the actuating force of an axial compression spring into a retracted neutral position which does not protrude axially from the guide sleeve, and which has a tip-side locking end and an oppositely arranged actuating end in connection with the actuator knob,
• wherein the actuator knob has an outer sleeve with which the actuator knob is movably mounted axially on the sleeve section of the guide sleeve,
• wherein the actuator knob comprises at least one internal locking projection which, in the locked position, engages in a locking manner in a corresponding recess in a side wall of the sleeve section of the guide sleeve,
• wherein the actuator knob is engaged under spring tension and fixed in a rotationally fixed manner with respect to an axial rotation about a center axis of the locking bolt, and in a neutral position, a fixed position of the at least one internal locking projection which is blocked against rotation is cancelled and the actuator knob is rotatable about the center axis.
