Scanning device

The invention provides a scanning device. The scanning device comprises a supporting rod, a supporting arm, a connecting arm, a fixing table and a scanner, wherein the supporting arm is rotatably arranged on the supporting rod around a first rotating shaft; the connecting arm is rotatably arranged on the supporting arm around a second rotating shaft; the fixing table is rotatably arranged on the connecting arm around a third rotating shaft; the scanner is arranged on the fixing table; and the rotating position of the scanner around the three rotating shafts is adjusted by rotating the supporting arm, the connecting arm and the fixing table, so that all-directional 360-degree scanning of the scanning device is realized. Based on the technical scheme, the rotating freedom degree of the scanner around the x axis, the y axis and the z axis can be adjusted by rotating the supporting arm, the connecting arm and the fixing table, so that the rotating range of the scanner is increased, all-directional 360-degree dead
