When the rotating rod 40 rotates, the cooperation between the guide rod 46 and the guide plate 47 drives the servo motor 15 to move together when the rotating rod 40 moves.

[0053] The working principle of the utility model is as follows: when it is necessary to cut the stone, the stone is placed on the carrying plate 7, and the carrying wheel 8 is driven horizontally to drive the carried stone to move horizontally to the bottom of the main frame 4 on the horizontal slide rail 6, and the servo motor 15 is driven to rotate the four rotating screws 13 through the control cabinet at the same time, thereby driving the lifting frame 11 to rise toward the end of the main frame 4, so as to drive the carrying plate 7 to rise to the cutting opening 5, and then the rotating member 27 drives a plurality of rotating wheels 25 to rotate, so that the diamond wire 26 cuts the stone on the carrying plate 7, and the main frame 4 can be kept fixed while the stone on the carrying plate 7 is raised to cut, which will not cause the main frame 4 to shake, and it is not easy to cause wavy patterns on the surface of the stone after cutting; after the stone is cut, the servo motor 15 is driven to rotate the four rotating screws 13 at the same time, thereby driving the lifting frame 11 to descend toward the end of the pit groove 9, and the lifting frame 11 can be lifted and lowered through the perforations 12 when the lifting frame 11 rises and falls. The frame 11 passes through two ground piles 10, so that the cut stone can be moved outward on the horizontal slide rail 6 through the sliding wheel 8 of the bearing plate 7; when the rotating screw rod 13 drives the lifting frame 11 to rise toward the end of the main frame 4 or to descend toward the end of the pit groove 9, the lifting frame 11 is guided by the V-shaped groove 19 and the V-shaped surface 20 on the matching block 17 and the guide block 18 when the four rotating screw rods 13 drive the lifting frame 11 to rise and fall, which can increase the contact area between the two compared with the traditional guiding device, thereby improving the stability of the lifting frame 11 and further preventing the lifting frame 11 from shaking during the lifting process; when it is necessary to adjust the spacing between the V-shaped groove 19 and the V-shaped surface 20, first remove the fixing screw 23 from the first connecting plate 21 and the second connecting plate 22, then drive the top plate screw 24 to push the second connecting plate 22 to drive the matching block 17 to move toward the end of the guide block 18, and then install the fixing screw 23 on the first connecting plate 21 and the second connecting plate 22;When the closed-loop diamond wire 26 needs to be installed between several rotating wheels 25, the double-outlet shaft cylinder 38 at the upper end of the support plate 34 is started by the control cabinet to drive the moving block 35 to move to the second position at the end of the main frame 4. At this time, the double-outlet shaft cylinder 38 contacts the travel switch 39 to drive the double-outlet shaft cylinder 38 at the upper end to stop, so that the moving block 35 is disconnected from the matching groove 37 to allow the diamond wire 26 to pass between the moving block 35 and the support block 36. Then, the double-outlet shaft cylinder 38 at the upper end of the support plate 34 is started by the control cabinet to drive the moving block 35 to move to the first position at the end of the main frame 4, so that the moving block 35 is connected to the matching groove 37. To support the main frame 4, the double-axle oil cylinder 38 at the lower end of the support plate 34 is repeated to drive the moving block 35 to disengage from the support block 36 at the lower end, so that the diamond wire 26 passes between the moving block 35 at the lower end and the support block 36, and then the main frame 4 is supported again, and the diamond wire 26 can be passed through the wire installation opening 33 and connected to the rotating wheel 25 at the lower end, and then the top line triangle plate 30 is driven to rotate around its left end toward the main frame 4 end through the output end of the hydraulic rod, so that it drives the top line wheel 31 at the right end to press the diamond wire 26 against the rotating wheel 25, and the installation of the diamond wire 26 can be completed. ;
