[0023] The motor housing 2 is placed in the arc groove 32 opened in the middle of the support plate 3 and the heat dissipation fin 31. By rotating the threaded rod 6 on the U-shaped positioning frame 4 on both sides of the support plate 3, the positioning rod 61 on the inner side of the positioning frame 4 can move from the right side of the positioning frame 4 along the left side of the adjusting groove 41 under the cooperation of the adjusting groove 41 and the thread, so as to slide and insert the open groove 7 opened on the outside of the first flange 21 and the second flange 22 at both ends of the motor housing 2. Compared with the existing easily detachable servo motor, the positioning of the motor housing 2 can be released without removing the bolts from all around the motor housing 2, and the disassembly and assembly is more convenient. In addition, the arc surface in the middle of the motor housing 2 is tightly fitted with the inner wall of the arc groove 32 in the middle of the support plate 3 and the heat dissipation fin 31, so that the force area of ​​the motor housing 2 is increased, thereby improving the overall stability.

[0027] Then, by rotating the threaded rods 6 on the U-shaped positioning frames 4 on both sides of the support plate 3, the positioning rods 61 on the inner side of the positioning frames 4 can move from the right side of the positioning frames 4 along the left side of the adjusting groove 41 under the cooperation of the adjusting groove 41 and the thread, so as to slide and insert the opening grooves 7 provided on the outside of the first flange 21 and the second flange 22 at both ends of the motor housing 2 for positioning;
