The base 1 is made of granite, and its top surface is a horizontal surface by fine grinding. The base 2 is a long-strip-shaped I-shaped structure and is locked on the top surface of the base 1 by an expansion screw 11. Accordingly, even if the base 2 is slightly warped due to insufficient manufacturing accuracy, the base 2 can be pressed against the base 1 to be forcibly leveled, and the level of the base 2 can be ensured, based on the extremely high hardness of the granite base 1.
The base 2 has an upper top 21 extending towards both sides, which defines a first slide 22 for the two slides 4 to slide. The bottom end of the sliding seat 4 extends out of a pair of feet 41 and straddles the upper top 21 of the base 2, and the two feet 41 are locked and fixed to a bottom plate 42 extending below the upper top 21, so that the sliding seat 4 can only slide along the first sliding rail 22 and cannot leave the base 2 in other directions.
Two driving devices 5 connected to the sliding base 4 are disposed on the base 2 for driving the sliding base 4 to slide on the first sliding rail 22. In the embodiment, the top surface of the base 2 is concavely provided with a containing chamber 23, and two ends of the base 2 are provided with through holes 24, each driving device 5 comprises a screw 51 and a hand wheel 52, the two screws 51 respectively extend into the containing chamber 23 from the two through holes 24 and extend in the same direction as the first slide rail 22; one end of each screw 51 extending out of the through hole 24 is connected with the hand wheel 52. On the other hand, the bottoms of the two sliders 4 respectively have a screw connection portion 43, and are respectively screwed with a screw 51. With the above structure, as shown in fig. 3, the operator can rotate the hand wheel 52 to drive the corresponding screw 51 to rotate, and then drive the corresponding slide seat 4 to move along the first slide rail through the screw action.
