[0011] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0012] like Figure 1 , Figure 2 As shown, the frequency conversion ultrasonic vibration head device comprises a base module 1, a piezoelectric module 2 and a connecting module 3. The base module 1 is provided with an interface 4 matching the piezoelectric module 2. The piezoelectric module 2 is connected to the base module 1 through the connecting module 3. The connecting module 3 is provided with a connecting component 5 for connecting the piezoelectric module 2 and the base module 1. The connecting component 5 comprises a bracket 1 6 fixed on the connecting module 3, a movable bracket 2 7 and an elastic unit 8 for connecting the bracket 1 6 and the bracket 2 7. The bracket 1 6 provides a movable track for the bracket 2 7 by being fixed on the connecting module 3. The bracket 1 6 and the bracket 2 7 are connected to each other through the connecting module 3. An installation groove 9 is formed between the brackets 2 and 7, and an elliptical groove 10 is provided on the brackets 1 and 2, and a fixing block 11 for connecting with the installation groove 9 is provided on the piezoelectric module 2 and the base module 1. When the fixing block 11 is inserted into the installation groove 9, the fixing block 11 will expand the elastic unit 8 for easy installation, and elliptical buckles 12 for matching with the elliptical groove 10 are provided at both ends of the fixing block 11. When the elliptical buckle 12 of the fixing block 11 is combined with the elliptical groove 10, the elastic unit 8 will slowly reset, and the brackets 2 and 7 and the brackets 1 and 6 will clamp the fixing block 11 to prevent it from falling off.

[0013] In further detail, the elastic unit 8 includes an elastic frame 13 and a return spring 14 installed on the elastic frame 13 and having a return function.

[0014] To elaborate further, the connection module 3 is provided with an inner cavity 15 for moving the bracket 2 7, through which the bracket 2 7 can be moved in the connection module 3, and the connection module 3 has a shell 16 for protecting the inner cavity 15 to prevent the connection component 5 from being damaged by external impact.

[0015] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
