         1 . A device of plasma polishing a stainless steel wire comprising:
 at least one accommodation tank configured to accommodate negative-electrode polishing solution, a polished metal wire having a stainless steel substrate, a collection device, a direct current (DC) controller, and a direct current (DC) power generator;   wherein the collection device includes a supply segment and a rolling segment which are located outside two ends of each of the at least one accommodation tank respectively, at least two positive-electrode conductive rollers are arranged above the negative-electrode polishing solution of each accommodation tank and electrically connected with a positive electrode of an electric current, and each accommodation tank is connected with a negative electrode of the electric current, wherein a length of a part of the stainless steel substrate between any two adjacent positive-electrode conductive rollers depends on a resistance tolerance range of a length of a stainless steel wire between said any two adjacent positive-electrode conductive rollers, the polished metal wire is connected with a first isolative guide section coupling with the rolling segment, wherein a first cleaning tank is configured to clean the polished metal wire which does not move into each accommodation tank and is pulled by the rolling segment, and a second cleaning tank is configured to clean a plasma polished metal wire which moves across each accommodation tank and is pulled by the rolling segment, and multiple electric insulation structures are respectively mounted beneath bottoms of each accommodation tank, the supply segment, the rolling segment, the first cleaning tank, and the second cleaning tank.   
     
     
         2 . A method of plasma polishing the stainless steel wire using the device of  claim 1  comprising steps of:
 (a1). fixing the polished metal wire on the supply segment, wherein a first end of the first isolative guide section is connected with the connection portion of the stainless steel substrate, the first isolative guide section is rolled among multiple transmission rollers and the at least two positive-electrode conductive rollers, and the second end of the first isolative guide section is coupled with the rolling segment of the collection device, such that the first isolative guide section is delivered to soak in the negative-electrode polishing solution of each accommodation tank and to contact with the at least two positive-electrode conductive rollers by way of the multiple transmission rollers, thereafter a power supply is started so that the DC controller and the DC power generator transmit positive and negative electrode currents to each accommodation tank and the at least two positive-electrode conductive rollers respectively, wherein each accommodation tank is made of metal conductive material or includes metal conductive material accommodated therein so that a negative electrode area produces in the negative-electrode polishing solution, and a part of the first isolative guide section in each accommodation tank electrically insulates from the negative-electrode polishing solution, wherein when the first isolative guide section is continuously pulled and rolled by the rolling segment to contact with a first zone of each of the at least two positive-electrode conductive rollers, it electrically insulates from an exterior environment until the stainless steel substrate of the polished metal wire exposes; 
 (a2). pre-processing, wherein the stainless steel substrate of the polished metal wire is pulled and rolled by the rolling segment to move into the first cleaning tank so as to be cleaned in the first cleaning tank; 
 (a3). plasma polishing, wherein the stainless steel substrate of the polished metal wire is contentiously pulled and rolled by the rolling segment after the step (a2) so that the stainless steel substrate of the polished metal wire moves toward each accommodation tank, wherein the stainless steel substrate contacts with each positive-electrode conductive roller so that each positive-electrode conductive roller conducts electricity to the polished metal wire and the positive electrode of the electric current produces on the stainless steel substrate, thereafter the stainless steel substrate is pulled by the rolling segment to be soaked in the negative-electrode polishing solution, such that the stainless steel substrate contacts with the negative-electrode polishing solution to form a current loop, and the stainless steel substrate is plasma polished to reduce roughness and friction coefficient, wherein when the stainless steel substrate is pulled by the rolling segment to move across a second zone of each positive-electrode conductive roller, it electrically insulates from the exterior environment by using one of the multiple electric insulation structures; 
 (a4). post-processing, wherein the plasma polished metal wire after the step (a3) is pulled and rolled by the rolling segment to move into the second cleaning tank to be cleaned; and 
 (a5). rolling, wherein the collection segment rolls the plasma polished metal wire after the step (a4), and the supply segment supplies the polished metal wire to drive the stainless steel substrate having positive electrode to move into each accommodation tank, hence the polished metal wire is soaked in the negative-electrode polishing solution of each accommodation tank, thus plasma polishing the polished metal wire again. 
 
     
     
         3 . The device as claimed in  claim 1 , wherein multiple transmission rollers are arranged in each accommodation tank. 
     
     
         4 . The device as claimed in  claim 1 , wherein each of the at least one accommodation tank is made of metal conductive material or includes metal conductive material accommodated therein, and the metal conductive material is copper material. 
     
     
         5 .
