[0026] The technical solution of the utility model is further described below, but the scope of protection required is not limited to the description.

[0027] Example:

[0028] like Figures 1 to 7 As shown, a drilling template tool for a support seat includes a base 1 and a drilling template 2. The base 1 includes a side plate 3 and a bottom plate 4. The side plate 3 is arranged on the edge of one side of the bottom plate 4, so that the base 1 is L-shaped. A mandrel 5 is arranged on the side plate 3, and a fixing seat 6 is arranged on the bottom plate 4. The drilling template 2 is arranged on the side plate 3, and one side edge of the drilling template 2 is connected to the side plate 3. The drilling template 2 can fix and position the top of the rectangular surface of the support seat part to be drilled. The drilling template 2 is located above the mandrel 5 and the fixing seat 6.
