Description of the Invention (1) [Technical Field of the Invention] The present invention relates to a driving mechanism of a vacuum switching tube for driving the opening and closing of the vacuum switching tube, and a vacuum circuit breaker using the driving mechanism. [Previous technology] The driving mechanism of the conventional vacuum switch tube is connected to the movable contact driving rod of the vacuum switching tube fixed on the fixed contact side, and corresponds to the operation of the operating mechanism to drive the movable contact driving rod to the axial direction. Movement, so that the vacuum switch tube is opened and closed. The operating mechanism is provided on the frame, and the pin is connected to one end of the link mechanism formed by the link to rotate the link, and a driving force is applied to a movable contact driving lever pivotally provided on the other end of the link mechanism. . However, in the driving mechanism of the conventional vacuum switch tube, the connecting end of the movable contact driving rod rotates around the pivot axis of the link during the cut-off or turning-on operation, so that the movable contact is driven. The rod produces a forced displacement (ie, a rocking displacement) approximately perpendicular to the axis (radial) direction. Therefore, the vacuum switching tube is skewed, which causes a problem that the durability of the vacuum switching tube is reduced. The present invention has been developed to solve the above problems, and an object thereof is to provide a driving mechanism for a vacuum switching tube that does not impair the durability of the vacuum switching tube, and a vacuum circuit breaker using the driving mechanism. During the process, the radial force will not be applied to the movable contact driving rod of the vacuum switch tube. [Disclosure of the invention] The driving mechanism of the vacuum switching tube of the present invention is a driving mechanism for opening and closing the vacuum switching tube, which is provided with a freely rotatably arranged vacuum switching tube.

One end of the telescopic link mechanism 25 'is pivoted by a pin 14 on the follower guided by the guide 16 and the member 15 moves linearly; the other end is pivoted by a pin 2i on the outer insulation 3Λ mobile. Therefore, when force is applied to at least one of the cup, the second link 20, and the pin 19 that constitutes the telescopic link mechanism 25, the telescopic link mechanism 25 performs a telescopic motion. Therefore, the pin ^ can drive the movement of the contact driving lever 7 in the vertical direction in the figure.
