A removable T-shaped set screw 3 is threadedly connected to the middle position inside the bottom of the groove of the U-shaped scale frame. The height can be adjusted as needed. The top surface of the T-shaped set screw constitutes a normal support surface, which facilitates the positioning of the measured object. The principle of three-point circle positioning enables the measuring device to reach the measurement position more quickly and accurately, making the measurement results more accurate (and avoiding measurement errors caused by shaking of the measured object).

[0028] The vertical section of the connecting seat 4 is a clamping plate 45 opposite on both sides, the gap of the clamping plate corresponds to the thickness of the U-shaped ruler, and opposite bolt mounting holes 46 are arranged on the clamping plate and extend upward and downward; the bolt mounting hole 11 is arranged on the side wing plate of the measuring anvil of the U-shaped ruler, and the bolt 6 is arranged in the bolt mounting hole and is fixed and connected into an integrated body through the nut 7.

[0029] In the embodiment, the height of the horizontal section of the L-shaped connecting seat away from one side of the vertical section is smaller than that of the other side; the screw locking opening slot is more convenient, so as to enhance the stability of the installation of the micrometer.
