In an actual product, the installation hole 1c is a circular hole, and the outer peripheral surface of the barrel 2a is in contact with the inner side wall of the installation hole 1c, making the installation of the motor 2 more stable.

[0025] Specifically,

[0026] As Figure 2 and Figure 3 shown, the servo motor installation structure includes a circle of arc blocks 2b formed on the outer peripheral surface of the barrel 2a, and the arc blocks 2b and the barrel 2a are coaxially arranged. Each arc block 2b is pressed against the installation platform 1, and through holes are vertically penetrated through both ends of each arc block 2b. A bolt 3 is inserted into each through hole, and the arc block 2b is fixedly connected to the installation platform 1 through the bolt 3. Guide posts 2c are formed on both sides of the thickness of each arc block 2b on the outer wall of the barrel 2a, and the guide posts 2c and the barrel 2a are of an integral structure. The axis of the guide post 2c extends along the axial direction of the barrel 2a, one end of the guide post 2c extends to the middle of the corresponding arc block 2b, and the two guide posts 2c connected to the same arc block 2b are arranged side by side along the axial direction of the barrel 2a.
