Adjusting mechanism for installation of linear guide rail of ultra-high-speed numerical control machine tool

The invention relates to the field of numerical control machine tools, in particular to an adjusting mechanism for mounting a linear guide rail of an ultra-high-speed numerical control machine tool, which comprises a supporting seat, two first electric telescopic rods are fixedly connected to the top end of the supporting seat, and a supporting plate is fixedly connected to the top ends of the two first electric telescopic rods together; the front end of the supporting plate is fixedly connected with a second electric telescopic rod, and the front end of the second electric telescopic rod is rotationally provided with a connecting frame. Through the arrangement of the adsorption mechanism, a user anticlockwise rotates a second fastening bolt, the second fastening bolt can slide out of a second threaded hole at the moment, so that a mounting plate can be separated from a supporting seat, a spring can downwards push the mounting plate at the moment, and after a suction cup is tightly attached to the top wall of
