The guide sliding inclined surfaces 6 have a guiding effect on the sliding of the guide sliding mechanism 3, and the arc-shaped positioning grooves 5 have a limiting effect on the guide sliding mechanism 3;

[0041] The guide mechanism 3 includes a long flat plate 31, a long curved plate 32 and a plurality of ball bodies 33. The long curved plate 32 is attached to the guide slope 6. The long curved plate 32 is fixedly connected to the long flat plate 31 and extends into the arc positioning groove 5. The plurality of ball bodies 33 are arranged in the long curved plate 32 along a straight line. The surface of the ball body 33 is against the long flat plate 31.

[0042] The long arc plate 32 is provided with a plurality of slots 7, and the plurality of ball bodies 33 are respectively inserted into the plurality of slots 7, so as to facilitate the positioning and installation of the ball bodies 33 on the long arc plate 32;

[0043] The top surface of the slide rail body 1 is provided with a plurality of waist-shaped grooves 8, and the plurality of waist-shaped grooves 8 extend to the guide slide inclined surface 6. The plurality of adjusting bolts 4 are slidably connected in the plurality of waist-shaped grooves 8, and the lower end of the adjusting bolt 4 is screwed to the long arc plate 32, so that the adjusting bolt 4 can adapt to the position change of the long arc plate 32 and the long flat plate 31 on the guide slide inclined surface 6;
