By installing a reduction motor 26 in the top seat 20, and connecting a driving gear 27 to the output shaft of the reduction motor 26, the device can drive the driving gear 27 to rotate through the reduction motor 26, thereby controlling the rotation of the driven gear 23 and the internal threaded tube 24, further improving the degree of automation of the coupling agent application. The coupling agent cylinder 10 is provided to provide a storage and supply container for the ultrasound coupling agent, which facilitates the use and management of the coupling agent. By threading the top seat 20 at the top of the coupling agent cylinder 10, and installing the application head 30 at the bottom of the coupling agent cylinder 10, the structure of the device is more compact and reasonable, and the installation and disassembly of the application head is convenient.
