 first and second pad reciprocation eccentric cams, to each of which a rotation axle of the driving motor is eccentrically joined; and 
 first and second pad reciprocation rods, one end of each of the first and second pad reciprocation rods being installed on one of hinge brackets of the first and second rag attachment pads, and the other end of each of the first second pad reciprocation rods being installed on one of the first and second pad reciprocation eccentric cams, and 
   wherein the driving member is horizontally arranged on the base.   
     
     
         5 . The base member assembly of  claim 2 , further comprising:
 one or more pad reciprocation members configured to receive power from the driving member and to linearly reciprocate the rag attachment pads,   wherein the rag attachment pads comprise first and second rag attachment pads disposed on the front and rear sides of the bottom side of the base,   wherein the pad reciprocation members comprise first and second pad reciprocation members that are configured to receive the power of the driving member and to make the first and second rag attachment pads come close to and go away from each other,   wherein the pad guide members comprise first and second pad guide members configured to guide the linear reciprocation movement of the first and second rag attachment pads, and   wherein the base is formed with a through-hole,   wherein the driving member comprises a driving motor,   wherein the first and second pad reciprocation members comprise:
 first and second pad reciprocation eccentric cams, to each of which a rotation axle of the driving motor is eccentrically joined; and 
 first and second pad reciprocation rods, one end of each of the first and second pad reciprocation rods being installed on one of hinge brackets of the first and second rag attachment pads, and the other end of each of the first second pad reciprocation rods being installed on one of the first and second pad reciprocation eccentric cams, and 
   wherein the driving member is horizontally arranged on the base.   
     
     
         6 . The base member assembly of  claim 3 , further comprising:
 one or more pad reciprocation members configured to receive power from the driving member and to linearly reciprocate the rag attachment pads,   wherein the rag attachment pads comprise first and second rag attachment pads disposed on the front and rear sides of the bottom side of the base,   wherein the pad reciprocation members comprise first and second pad reciprocation members that are configured to receive the power of the driving member and to make the first and second rag attachment pads come close to and go away from each other,   wherein the pad guide members comprise first and second pad guide members configured to guide the linear reciprocation movement of the first and second rag attachment pads, and   wherein the base is formed with a through-hole,   wherein the driving member comprises a driving motor,   wherein the first and second pad reciprocation members comprise:
