Then, the metal round rod 3 is inserted into the fixed sleeve 8 and fixed through the locknut 9, so as to fix the metal round rod 3 on the aluminum formwork 2, and the embedded casing 1 is fixed accordingly, preventing the embedded casing 1 from being displaced during the concrete pouring process. Then, the small laser emitting device 7 can emit laser points as a centering auxiliary alignment positioning device for the embedded casing 1 on the horizontal or vertical plane, and can achieve high-precision positioning for the positions that need to be continuously drilled.

[0025] The variable-diameter fixing component 4 of the circular ring includes a circular plate 401 with a circular groove 402 opened at one end.
