[0013] 1. The utility model provides a U-shaped frame, on which threaded rods, clamping blocks, knobs, guide posts, anti-skid pads and other components are provided. The position of the clamping blocks can be adjusted by relative threaded movement between the threaded rods and the U-shaped frame, so that the clamping blocks and the U-shaped frame can be clamped on the profile as a whole, thereby ensuring stability during drilling and marking positioning and preventing deviation.

[0014] 2. The utility model arranges a combination of a sliding sleeve and a sliding bar on the side of the U-shaped frame, and then fixes a positioning hole plate on the sliding bar with a connecting plate. The positioning hole plate is provided with holes of various shapes, and the positions of different holes can be adjusted by relative sliding between the sliding bar and the sliding sleeve, so as to facilitate the engraving of drilling holes of different shapes.
