[0033] Working principle: first push the base, the universal wheel 17 rotates, and the base is pushed into the lower side of the CNC machine tool that needs to be moved. The motor 11 is controlled to rotate through the controller 5. The motor 11 drives the corresponding bidirectional screw 8 to rotate. The bidirectional screw 8 drives another bidirectional screw 8 to rotate through the transmission of two synchronous wheels 9 and a synchronous belt 10. The two bidirectional screws 8 simultaneously drive the corresponding sliders 6 to slide along the screw box 4.
