The second grooves 712 are symmetrically arranged on the second center line B of the bottom plate 1, and the extension lines of the second grooves 712 point to the intersection of the first center line A and the second center line B. A circular relief hole 9 is provided with the intersection of the first center line A and the second center line B as the center. Four first mounting holes 72 are provided in the first groove 711, and three first mounting holes 72 are provided in the second groove 712. The lower surface of the bottom plate 1 is a precision machined surface to ensure the accuracy of the tooling installed on the turntable of the test equipment.
