The outer edge of the first limiting piece 281 abuts against the outer ring of the first bearing 280, and the outer edge of the second limiting piece 282 abuts against the inner ring of the first bearing 280, so that the first limiting piece 281, the second limiting piece 282 and the inner wall of the first accommodating cavity 251 form a groove for the first bearing 280, to limit the movement of the first bearing 280 in the third direction, avoid the deviation of the bearing during rotation, thereby affecting the rotation deviation of the first mounting portion 211 and reducing the accuracy of simulation. Similarly, the third limiting piece 361 and the fourth limiting piece 362 are annular limiting piece structures, and the second shaft body 312 is provided with spaced annular grooves in the axial direction.
