Large-lift high-stability precise wedge-shaped adjusting mechanism

The large-lift high-stability precise wedge-shaped adjusting mechanism is characterized in that the large-lift high-stability precise wedge-shaped adjusting mechanism comprises a bottom plate, a groove is formed in the bottom plate, and the bottom of a vertical guide rail is fixedly connected into the groove; the left and right side surfaces of the bottom end of the vertical guide rail are respectively provided with a through hole; the lower wedge block penetrates through the through holes and can move left and right; the upper wedge block is arranged in the vertical guide rail, and the upper wedge block is adjusted to move up and down in the vertical guide rail by moving the lower wedge block left and right; the lower end surface of the upper wedge block is a parallel inclined surface matched with the upper wedge surface of the lower wedge block; the upper end face of the upper wedge block is used for making contact with the vertical moving plate. Threaded holes are formed in the left side face and the right
