[0028] A plurality of locking devices 4 are respectively provided between the bottom plate 12 and the four columns 11 for locking the two correspondingly to each other. The locking devices 4 include anchor bolts 41 fixedly riveted to the base 9 and nuts 42 sleeved on the anchor bolts 41 through threaded connection. The lower end of the column 11 is provided with a support foot 111 that fits the upper surface of the bottom plate 12. The support foot 111 is provided with a first U-shaped groove 112 extending from the middle of the support foot 111 to the outside. The plate body of the bottom plate 12 is evenly distributed with a plurality of There is a second U-shaped groove 121 extending outward from the middle of the plate body of the base plate 12, and the diameter of the first U-shaped groove 112 and the second U-shaped groove 121 are both larger than the diameter of the anchor bolt 41 and smaller than the diameter of the nut 42. Each anchor bolt 41 is respectively arranged on the first U-shaped groove 112 and the second U-shaped groove 121, so that the plate body of each column 11 and each base plate 12 is fixedly locked on the anchor bolt 41 through the nut 42, that is, the plate body of each column 11 and the base plate 12 is fixedly connected to the base 9.

[0029] Preferably, the locking device 4 further includes a stopper 43 for preventing the nut 42 from being separated from the anchor bolt 41, an elastic washer 44 disposed between the support foot 111 and the nut 42, and a damping washer 45 disposed between the support foot 111 and the elastic washer 44. The stopper 43, the elastic washer 44, and the damping washer 45 are all sleeved on the anchor bolt 41.

[0034] The working principle is: the driving motor 342 drives the ball screw 341 to rotate, so that the cutting frame 31 moves up and down smoothly in the accommodating space, and the vertically arranged linear guide column 32 can further stabilize the path of the cutting frame 31 when moving up and down, ensuring that it will not shake when moving up and down, and then the stone arranged on the base 9 is planned to be cut.

[0035] When the utility model leaves the factory, the device can be divided into a cutting device 3 with a more complex structure, wherein the longer guide column 32 and the ball screw 341 in the cutting device 3 can also be disassembled. This part is more difficult to assemble, and can be assembled into one piece by a more skilled engineer in the factory (fixed place), and then the top plate 13 formed by splicing a plurality of plates can be transported to the site together; other simpler parts can be transported to the site in parts, and the equipment can be installed on site. A reinforced concrete base 9 is pre-made on site, and a number of dry anchor bolts 41 are pre-embedded in the base 9.
