Block for resisting counterclockwise running of lathe carriage

The utility model discloses a counterclockwise rotating push block of a lathe saddle, which comprises a fixing block. The utility model is characterized in that the fixing block is provided with a rotating hole, wherein one end of a rotating rod penetrates the rotating holes of the fixing block and is fixed by a nut, and the aperture of the rotating hole positioned at the upper section of the fixing block is a little bigger than the nut and is bigger than the aperture of the rotating hole positioned at the lower section of the fixing block. A return spring is sheathed on the rotating rod below the nut, the return spring is arranged in the rotating hole positioned at the upper section of the fixing block, and the other end of the rotating rod is fixedly connected with a side surface at one end of a push rod, wherein an adjusting nut is screwed at the front end of the push rod. Therefore, the push rod and the adjusting nut at the front end of the push rod can support the saddle, so that the saddle can not move and rotate. The saddle and a small carriage are firmly arranged to achieve the function of improving work efficiency, therefore an intermediate screw on the saddle does not need to be tightly screwed. The service life of the screw is increased, and the service life of the contact surface of the saddle and the small carriage is also increased and extended, and precision and properties are improved. The utility model has the advantages of simple structure, simple operation, etc.
