Stability is also unstable.Higher industry is required for product stability, and is set using instrument in harsh environments
Standby then be badly in need of that a kind of vibration force is larger, the piezo-activator of stability of characteristics makes up the market demand.
But knot is on the one hand folded to realize that larger driving scope is glued using lamella due to piezoelectric actuator
Structure, and be ceramic-like hard brittle material, thus in use often due to end face unbalance stress, side by shearing force, moment of flexure,
The factors such as moment of torsion, vibrations, impact and inertia force cause the damage of piezoelectric ceramics so that the coefficient of losses of piezoelectric ceramics is very high.Separately
On the one hand due to characteristics such as sluggish existing for piezoelectric ceramics and creeps, the output of the displacement in motion process is caused in non-linear,
Mobile accuracy is poor.
In order to overcome disadvantages mentioned above, the positive innovation research of those skilled in the art is a kind of new new to create
Piezoelectric actuator.
The content of the invention

It is described between second ceramic vibrator and second oscillating plate with first ceramic vibrator, second contact
The both ends of second contact connect second oscillating plate and second ceramic vibrator.
Further say, be additionally provided with connecting rod, the first oscillating plate and second of each vibration unit of connecting rod connection
Oscillating plate, the connecting rod connect two adjacent vibration units.
Further say, first ceramic vibrator, first oscillating plate, first contact and the described second ceramics
Oscillator, second oscillating plate and the arrangement of second contact parallel vertical.
Further say, the quantity of the vibration unit is at least 1, and more bullets are provided between each vibration unit
Spring, the both ends of the spring connect two adjacent vibration units.
Further to say, the quantity of first contact is no less than 3, and the quantity of second contact is no less than 3, and
Described first quantity got an electric shock is equal with the quantity of second contact.
Further say, the connecting rod is arranged vertically with first oscillating plate and the second oscillating plate.
Further to say, first ceramic vibrator and second ceramic vibrator are round ceramic oscillator, described first
Oscillating plate and second oscillating plate are circular vibration plate, the diameter phase of first ceramic vibrator and second ceramic vibrator
Deng.
The beneficial effects of the invention are as follows：
The present invention is provided with multiple vibration units, and the quantity of vibration unit can be set according to different demands, is met for difference
