Be applied to novel electrochemical device among solid polymer condenser manufacturing procedure, the tetrapod of mouthful font underframe have welded a vertical braces leg separately, and the in thevertical position is on the top at the four corners position of mouth font underframe respectively through the welding for the sill bar end of four square pole settings, and the ejector pin of four square pole settings end fastens respectively in the tetrapod of mouth font top frame through the welding, electrochemical electrodes probe cell body is locked through the screw in imbedding mouthful font top frame downwards, and there is an inlet pipe bottom of electrochemical electrodes probe cell body and arranges and expect the pipe through the welding intercommunication, arranges the exit end of expecting the pipe and installs a switching valve no. 2, and a switching valve no. 1 is installed to the entrance point of inlet pipe, and the last pipe end and the pump body of inlet pipe are linked together, and the pump body and drive pump's operation is connected to the motor. The utility model has the characteristics of machining efficiency is high, the processing effect is good, the practicality is stronger.
