The invention relates to the field of design of carbon-free trolley operation, in particular to a carbon-free trolley fine adjustment mechanism and a carbon-free trolley. The carbon-free trolley fineadjustment mechanism comprises an XY-axis mover, an X-axis mover and a Y-axis mover, the XY-axis mover comprises a carrying plate, a guide rod, a sliding block and a rubber band connector which are sequentially connected up and down, and the sliding block can move along the guide rod left and right; and the carrying plate is connected with the Y-axis mover, and the sliding block is connected withthe X-axis mover. According to the carbon-free trolley fine adjustment mechanism, the XY-axis mover is separately connected with the X-axis mover and the Y-axis mover, the horizontal position and perpendicular position of the X-axis mover and the Y-axis mover are controlled through the XY-axis mover, position changing of the rubber band connector is controlled through loosing and tightness of a rubber band on the rubber band connector, and the problems that the carbon-free trolley cannot realize motion trail fine adjustment, the assembly difficulty of the carbon-free trolley is high and assembly time is long of the prior art are solved.
