The specific embodiment
Below in conjunction with accompanying drawing and implementation process the utility model is further described.
With reference to figure 1, Fig. 2, Fig. 3, Fig. 4, the utility model is equipped with cylinder cantilever 18 small in ends, broad in the middle in support set 1 centre bore, first magnet exciting coil 4, first spacer ring 3, first cushion pad 13 and magnetic shield 2, the first magnet exciting coils 4 and 1 of support set are housed on the small column of cylinder cantilever 18 side direction in support set 1 broad in the middle successively are filled with magnetic flow liquid 11; Cylinder cantilever 18 broad in the middle is equipped with second magnet exciting coil 5, second spacer ring 6 and second cushion pad, 9, the second magnet exciting coils 5 successively on the small column of support set 1 lateral direction and 1 of support set is filled with magnetic flow liquid 11; By end cap fixing hole 15 end cap 8 is installed at support set 1 opening part, stretch out on cantilever 18 small columns outside the end cap 8 terminal pad 7 is housed, first magnet exciting coil 4 and second magnet exciting coil 5 join by the controller of through hole and outside with first coil lead 12, second coil lead 10 respectively, have the groove 19 that five equilibrium is arranged on cantilever 18 faces of cylinder broad in the middle, trip bolt 17 screws in from the hole of support set 1, cantilever 18 is produced under groove 19 guiding to endwisely slip, terminal pad 7 is installed on the cantilever 18 by external screw thread 21, and realizes circumferentially fixing by set screw hole 20.
