Embodiment Construction
[0009] Now in conjunction with the accompanying drawings, the technical content of the present invention will be further described.
[0010] Such as figure 1 , 2 As shown, the silver paste tank 1 is built with conductive silver paste 2, and one end of the silver paste tank 1 is equipped with a bearing 4, and one end of the cylindrical rod 3 passes through one end of the silver paste tank 1, and the other end is connected with the bearing 4 at the other end of the silver paste tank 1. Fixed; the piezoelectric ceramic sheet 5 is placed on the cylindrical rod 3, and the circular surface of the piezoelectric ceramic sheet 5 is perpendicular to the length direction of the cylindrical rod 3, and the piezoelectric ceramic sheet 5 is provided with an electrode 6.
[0011] The cylindrical rod 3 is made of ceramics or metal with a surface roughness of 2-5 grades, and the roughness requirement is to prevent slipping during connection operations. The diameter of the cylindrical rod 3 ca...
