The driving end of the second motor 11 drives the lead screw 12 to rotate. Since the lead screw 12 is meshed and connected with the threaded groove, the lead screw 12 has a driving tendency to move the moving seat 10. The bearing seat moves along the path of the salt guide groove 13 under the action of the guide rod 14, and the distance from the first bearing seat 4 to the arc support plate 3 is adjusted.
