1. A cleaning device, comprising:
a main body,
a driving assembly comprising:
a driving device arranged on the main body, and having a driving shaft extending toward a bottom of the main body;
a movable bracket movably connected to the bottom of the main body and spaced from the driving shaft, a movement direction of which is substantially perpendicular to an extension direction of the driving shaft; and
at least one transmission member connected to the movable bracket and the driving shaft which drives the movable bracket to reciprocate back and forth through the at least one transmission member; and
a cleaning assembly detachably connected to the movable bracket, so that the cleaning assembly reciprocates back and forth with the movable bracket to clean the surface to be cleaned back and forth;
wherein the at least one transmission member comprises:
a first transmission member fixedly connected to the driving shaft; and
a second transmission member provided with a first connecting part and a second connecting part, wherein the first connecting part is rotatably connected to the first transmission member, and a center distance between the first connecting part and the driving shaft in a direction perpendicular to the driving shaft is defined as a first distance, wherein the second connecting part is rotatably connected to the movable bracket, and a center distance between the second connecting part and the first connecting part in the direction perpendicular to the driving shaft is defined as a second distance, and wherein the first distance and the second distance are both non-zero, and the second distance is greater than or equal to the first distance, and wherein the first connecting part comprises a rotating main body connected to an end of the convex shaft away from the movable bracket, wherein the second connecting part comprises a convex shaft.
