The drill jig sleeve is disposed in the mounting hole 321, and a mounting cavity is formed in the drill jig sleeve and is used for a drill bit required by drilling operation to pass through. And one side of the slide block, which is far away from the angle ruler, is taken as a theoretical length value, and the axis of the mounting hole 321 is collinear with the axis of the mounting cavity.

Specifically, the slider 320 has a cubic shape, such as a rectangular parallelepiped, as a whole. Thus, the front end face of the slide block can be directly used as a reference surface for length measurement. According to the scale corresponding to the reference surface, the actual length value can be directly calculated by combining the distance between the axis of the installation cavity and the reference surface. Meanwhile, in order that the slider 320 can stably slide, the thickness of the slider 320 may be twice or other multiples of the thickness of the length scale 200. Thus, the overall thickness of the slider 320 is ensured to be small, the center of gravity is low, and the stability of the slider 320 can be improved.
