[0034] Working principle and process:

[0035] When the staff uses the handle shell 1 to control the operation of the ultrasonic therapeutic device, after the operation is completed, before the handle shell 1 needs to be put back to the storage position, the staff can transmit a signal to the PCB control circuit board 2 through the controller 8 at the top of the handle shell 1 to control the micro servo motor 51 in the automatic child lock and unlocking component 5 inside the handle shell 1 to drive the threaded shaft 53 at the end of the main shaft to rotate, thereby driving the outer clamping slider 54 to move under the frame 4 and move to the top of the clamping slider 54 through the guide shaft 56, so as to limit the clamping slider 54 and prevent the clamping slider 54 from rotating further, so that other personnel cannot pass through. The push switch 6 of the handle shell 1 controls the PCB control circuit board 2 inside the handle shell 1, which effectively prevents children from being curious and manipulating the handle shell 1 to damage the ultrasonic therapeutic device. At the same time, the lock buckle 9 on one side of the handle shell 1 can be pressed to move it to the outside of the limiting tripod 11, and the lock buckle 9 is pushed to the outside of the limiting tripod 11 structure by tensioning the first spring 12. With the positioning pin 13 and the second spring 14, the lock buckle 9 can be quickly locked. The positioning pin 13 can be directly inserted into the sensing area of ​​the PCB control circuit board 2, thereby locking the controller 8 and stopping the manipulation of the handle shell 1, which is safer to use.
