[0025] As a further implementation of this solution, the support frame assembly 2, the base platform assembly 4, and the sound collection cover 5 are on the same axis. The lower end surface of the sound collection cover 5 is parallel to the upper end surface of the base platform assembly 4. The included angle between the support frame assembly 2 and the base platform assembly 4 is 90°. Such a design is more reasonable, which is beneficial to improving the fit between the device structures and strengthening the stability of the device;

[0026] As a further implementation of this solution, the vertical section of the grooved ring frame 21 is rectangular. A number of first balls 23 are provided. The first balls 23 are evenly distributed at equal intervals in a circular array in the inter-frame sliding groove 22. Two support columns 24 are provided. The two support columns 24 are parallel to each other. Such a design can make the components support each other better and improve the stability of the device;

[0027] As a further implementation of this solution, the upper end of the rotating rod 31 is in contact with the first ball 23. Two anti-collision blocks 32 are provided. The two anti-collision blocks 32 are symmetrically distributed left and right. A number of shock-absorbing particles 33 are provided. Each shock-absorbing particle 33 is parallel to each other.

[0031] Working process: During the use of the device, when a person steps on the pressure acquisition block 43, the squeezed pressure acquisition block 43 will transmit a signal to the reaction short rod 47 through the pressure induction platform 42. When the reaction short rod 47 receives the signal and transmits it to the grooved round platform 45, since the two human feet are symmetric left and right, the circuit board inside the grooved round platform 45 can send corresponding instructions to the control module 35 according to the position of the pressure acquisition block 43 that is squeezed. After receiving the instruction, the control module 35 will control the portrait collector 34 to drive the rotating rod 31 to rotate between the support frame assembly 2 and the base platform assembly 4. The first balls 23 provided on the inner side of the frame chute 22 and the second balls 49 provided on the inner side of the table chute 48 can reduce the friction force received when the rotating assembly 3 rotates, so that the rotating assembly 3 can quickly rotate to a suitable position. When the rotating assembly 3 rotates to a suitable position, the front end of the portrait collector 34 will face the front of the human body. Then, the control module 35 will send a signal to the sound wave emitter 6. When the sound wave emitter 6 receives the signal, it will emit a sound wave. After the sound wave encounters the human body and is blocked, it rebounds and is received by the sound receiving cover 5. The sound wave emitter 6 sends corresponding instructions to the control module 35 according to the duration of receiving the sound wave through the sound receiving cover 5. After receiving the instruction, the control module 35 will control the portrait collector 34 to slide to a suitable position outside the rotating rod 31, and the device will perform image acquisition on the human body.
