Power adjusting device of anorectal therapeutic apparatus

The invention discloses a power adjusting device for an anorectal therapeutic apparatus, which is characterized in that a differential circuit 1 performs differential operation on a high-frequency signal output by an OCL power amplifier circuit and a standard power signal, and performs differential operation on the output of a frequency sensor J1 and the output of a frequency sensor J2; an operational amplifier AR8 and an operational amplifier AR9 are respectively used for comparing the output of an operational amplifier AR5 with a differential voltage upper limit and a differential voltage lower limit, an inverse proportion additive operation circuit is used for carrying out additive operation on the output of a silicon controlled rectifier Q10 and the output of a silicon controlled rectifier Q12, when a relay K4 is conducted, resistors R3-R4 form an attenuation circuit to be connected with a base electrode of a triode Q1, and when the relay K4 is not conducted, the resistor R3-R4 forms an attenuation circui
