Referring to fig. 4, 5 and 8, in an embodiment, the mounting surface 110 includes a top surface of the first mounting boss 140, and a width of the first mounting boss 140 is smaller than a width of the first guide rail 200; and/or the difference between the width of the first guide rail 200 and the width of the first mounting boss 140 is not less than 0.1mm and not more than 2.0 mm. By such arrangement, the width of the first guide rail 200 is greater than the width of the first mounting boss 140, so that the first fastening member 400 can be abutted against the side edge of the first guide rail 200, and the structure of the first fastening member 400 can be optimized. Specifically, the first fastening member 400 includes a first sub-fastening member 410 and a second sub-fastening member 420, the first pressing surface 411 of the first sub-fastening member 410 may be a plane, the plane is easy to process, and the first pressing surface 411 arranged in a plane can not only abut against the side edge of the first guide rail 200, but also abut against the groove wall of the first mounting groove 120, thereby simplifying the structure of the first sub-fastening member 410. Similarly, the third extrusion surface of the second sub-fastening member 420 can be a plane, the plane is easy to process, and the third extrusion surface arranged in the plane can not only abut against the side of the first guide rail 200, but also abut against the groove wall of the second mounting groove 130, thereby simplifying the structure of the second sub-fastening member 420.

Meanwhile, the cast iron material also has good vibration resistance, has little influence on the straightness of the guide rail when the cross beam guide rail structure works, and has obvious vibration resistance and mechanical strength compared with the existing cross beam 100 which is made of marble. Therefore, the cross beam 100 is made of cast iron, and stability of the cross beam guide rail structure is improved.
