FIELD: measuring technique.
SUBSTANCE: device comprises housing with two pairs of supports for basing the inner cone and indicator provided with the indicating head. The housing is provided with levers. The first and second levers are provided with measuring tips. The indicator is connected with the second lever by means of indicating head. The housing is made of a cylindrical rod. The first lever is mounted on the cylindrical rod for permitting axial movement. The second lever is unmovable and is mounted for permitting rocking. The second lever is a double-arm lever. One of the arms is provided with the measuring tip mounted coaxially to the measuring tip of the first lever. The other arm is provided with a pivot spring-loaded to the indicating head to provide a contact with it. Each of the supports are mounted on the cylindrical rod for permitting dismounting.
EFFECT: expanded functional capabilities and simplified structure.
