The limiting rod 7 is fixedly arranged on the outer surface of the bidirectional threaded rod 5. The two fixing plates 6 are slidably arranged in the two rectangular grooves 8, respectively. The two fixing plates 6 are in threaded connection with the bidirectional threaded rod 5. A hexagonal groove 14 is formed in the front surface of the bidirectional threaded rod 5.

The semi-annular plate 9 is slidably arranged in the inside of the receiving groove 10, and the semi-annular plate 9 is in sliding insertion with the inside of the right circular groove 4.

[0027] Further, the two bidirectional threaded rods 5 drive the fixing plates 6 to move close to or away from each other, so that the fixing plates 6 can fix linear bearings of different lengths in the mounting seat 1, thereby improving the application range of the mounting structure. The two semi-annular plates 9 are rotated to loosen the two bidirectional threaded rods 5, and the two fixing plates 6 on the front side are removed, so that the bearing in the mounting seat 1 can be removed and replaced, thereby facilitating the replacement of the linear bearing by the staff and improving the work efficiency of the staff.

[0028] Further, the number of auxiliary fixing mechanisms is two, and the two auxiliary fixing mechanisms are arranged in the two mounting seats 1, respectively, and are arranged in a left-right mirror image.
