One end of the digital display fixing block is inserted into the through hole, and the detection end of the digital display dial indicator passes through the digital display fixing block.

[0008] Furthermore, the testing fixture also includes a base, and the drive module is connected to the base via a slide rail assembly.

[0009] Furthermore, the slide rail assembly includes a guide rail base and a guide rail cover plate. The guide rail base is fixed on the base, and two rows of guide rails are fixed symmetrically in mirror image on the upper surface of the guide rail base. The guide rail cover plate is placed above the guide rails and is slidably connected to the guide rails. The lower ends of the two moving blocks are positioned and connected to the upper surface of the guide rail cover plate by multiple positioning pins and multiple fixing screws. The digital display limit block is fixed on the end face of the guide rail cover plate near the digital display dial indicator.

[0010] Furthermore, the longitudinal section of the guide rail cover is T-shaped, and the vertical part of the guide rail cover is located between two rows of guide rails.

[0011] Furthermore, each column of guide rails includes two spaced-apart guide rails, with a guide rail pad between the two guide rails. The guide rail pad is tightly fitted to the opposite sides of the two guide rails.

[0012] Furthermore, two baffles are provided symmetrically on both sides of the base along its length, away from the digital micrometer, and the two sides of the lower end face of the limiting block are closely attached to the upper end face of the baffles.

[0013] Furthermore, one of the baffles is provided with an elongated oval hole extending along the moving direction of the drive assembly, and two limiting pins are fixed in the elongated oval hole, with the inner end of the limiting pin abutting against the side of the guide rail cover.
