The rotating assembly 20 comprises a rotating support bearing 22, a rotating roller 23 and a driving gear ring 24, the rotating support bearing 22 is arranged on the circuit protection mechanism 4, a roller flange part 28 is arranged on the rotating roller 23, the rotating roller 23 is fixedly connected to the rotating support bearing 22 through the roller flange part 28, a roller guide thread groove 27 matched with the friction coating 8 is also formed in the rotating roller 23, and through threaded fit between the friction coating 8 and the roller guide thread groove 27, on one hand, the rotating roller 23 can be driven to rotate through the rising of the elastic unidirectional damping sliding cylinder 5, and on the other hand, the rotating roller 23 can continuously rotate for a long time due to the characteristic that the rotating resistance of the rotating roller 23 is large but the friction loss is small, so that the purpose of prolonging the sounding time is achieved; the drive ring gear 24 is fixedly connected above the drum flange 28.

As shown in fig. 16, when the battery 36 is charged, the power can be directly supplied to the active buzzer 34 through the battery 36, and when the battery 36 is fed, the ac power generated by the rotation of the generator 25 is rectified by the rectifying circuit, and the generated dc power can drive the active buzzer 34 to generate a sound.
When the portable electronic device is particularly used, under the condition that the storage battery 36 is electrified, a patient only needs to lightly press the electronic button 7, the active buzzer 34 can be controlled to make a sound through a signal sent by the electronic button 7, and call information can be synchronously and remotely sent to other terminals, so that the common function of the portable electronic device is realized;
when the storage battery 36 is in a feeding state, the active buzzer 34 cannot be triggered only by pressing the electronic button 7, at the moment, the electronic button 7 needs to be slapped by using larger force, at the moment, the electronic button 7 is driven to descend together with the self-guiding button 6 and the elastic unidirectional damping slide cylinder 5 under the slapping force, when the elastic unidirectional damping slide cylinder 5 descends, the roller V-shaped elastic parts 10 can be easily deformed, so that the friction coating 8 is not matched with the roller guiding thread groove 27 through deformation shrinkage of each group of roller skirt parts 9, and in the process, the elastic unidirectional damping slide cylinder 5 can drive the rotary roller 23 under the elasticity of the reset spring 16 due to extremely small friction force between the roller external thread 12 and the cylindrical spiral friction increasing thread 19;
after the hand is loosened, the unidirectional delay reset mechanism 1 rebounds under the elastic force of the reset spring 16, and the roller skirt 9 cannot jump due to the tendency of opening when the roller V-shaped elastic part 10 moves upwards, so that the roller skirt 9 cannot help the roller external thread 12 to pass through the roller guide thread groove 27 through self deformation, and the rotary roller 23 can only rotate under the transmission relation between the roller external thread 12 and the roller guide thread groove 27;
the rotation resistance of the rotary drum 23 is large, but since the frictional loss in rotation is very small, the rotary drum 23 can be kept relatively smoothly rotated for a long period of time;
when the rotary drum 23 rotates, the driven gear 26 is driven to rotate by the driving gear ring 24, and when the driven gear 26 rotates by the motor input shaft 29, the generator 25 can generate alternating current, and the generated alternating current can drive the active buzzer 34 to sound after being rectified by the control circuit 35;
the sound level of the active buzzer 34 varies with the level of the current, and the duration of sound generation is the duration of power generation, that is, the duration of rotation of the rotary drum 23.
Through continuous beeping, good calling warning effect can be achieved under the condition of feeding.
The whole working flow of the invention is just the above, and the step is repeated when the invention is used next time.
