Specifically, the scale 4 is provided on the right part of the upper end surface of the substrate 1, and the indicator mark 5 is provided on the right part of the upper end surface of the slider 2. The indicator mark 5 is an arrow pointing to the scale 4, and the arrow points to the right side. There are gaps between the left and right ends of the slider 2 and the inner wall of the substrate 1 to prevent the slider 2 from being worn. In addition, while retaining a gap between the right end of the slider 2 and the inner wall of the substrate 1, the right end of the slider 2 is as close to the inner wall of the substrate 1 as possible to reduce the distance between the arrow and the scale 4, so that the arrow can more accurately indicate the value of the scale 4.

[0018] like Figure 1 As shown, the connection structure 6 includes a through hole provided on the side wall of the substrate 1, specifically, provided on the front side wall of the substrate 1, and the through hole penetrates the front side wall of the substrate 1 in the front-to-back direction, so that the through hole is connected with the accommodating cavity 7. When connected with the dial gauge, the probe of the dial gauge extends from the through hole into the slider 2, and the measuring rod of the dial gauge is connected in the through hole, as shown in FIG. Figure 2 shown.

The axis of the ball screw 31 is arranged along the sliding direction of the slider 2, and the two ends of the ball screw 31 are respectively rotatably connected to the front and rear ends of the base plate 1. The ball screw 31 is connected to the slider 2, and the driving member 32 is connected to the base plate 1 and drives the ball screw 31 to rotate. The driving member 32 is a handle, and the handle is connected to the ball screw 31. In this embodiment, the handle is connected to the front side end face of the base plate 1; in addition, a guide rod 8 is also connected to the base plate 1. The front and rear ends of the guide rod 8 are respectively connected to the front and rear ends of the base plate 1. The guide rod 8 and the ball screw 31 are both arranged along the front and rear direction. The slider 2 is slidably connected to the guide rod 8. Specifically, the guide rod 8 is inserted into the slider 2 to realize the sliding connection between the two. A sliding sleeve is also arranged between the guide rod 8 and the slider 2 to reduce the sliding friction. As shown Figure 1 and Figure 2As shown, the ball screw 31 and the guide rod 8 are respectively connected to the left and right parts of the slider 2, and the through hole is located between the ball screw 31 and the guide rod 8.

[0020] When the utility model is in use, according to the required calibration value, the driving component 3 is used to drive the slider 2 to move, so that the indication mark 5 on the slider 2 indicates the scale 4 corresponding to the required calibration value, and then the dial indicator to be calibrated is connected to the connecting structure 6, and the probe of the dial indicator is abutted against the slider 2 to calibrate the dial indicator. In situations where different calibration values ​​are required, different calibration values ​​can be obtained by simply changing the position of the slider 2, and different usage requirements can be met with only one calibration base.
