Embodiment Construction
[0019] see figure 1 with figure 2 , including a hollow cylindrical shell formed by connecting the upper cover 1 and the base 5, and the shell is made of a metal material with good heat dissipation performance. A magnetostrictive rod 2, a fixed support 6, a coil support 8, a drive coil 7, a transmission rod 3 and an output device 9 are respectively arranged along the axis in the housing, and the above-mentioned parts are coaxially arranged. By applying a changing magnetic field, the magnetostrictive rod 2 can expand and contract in the axial direction; the fixed bracket 6 is located on the periphery of the magnetostrictive rod 2 and is made of a magnetically permeable material for providing a bias magnetic field to the magnetostrictive rod 2 Magnetic conduction and positioning; the fixed bracket 6 is cylindrical with one end closed and the other open, and the magnetostrictive rod 2 is a cylinder, which is accommodated in the hollow portion of the cylindrical fixed bracket 6 ....
