The invention discloses portable multifunctional electric power detecting equipment. A micro motor is fixed to the back side of the casing upper end of a clamp type meter. Two parallel strip-shaped plates at the left side of a button are also included. Two rollers which extend out of the edge of the two strip-shaped plates are arranged between the two strip-shaped plates. The two rollers are at two ends of the strip-shaped plates. The rolling shafts of the rollers vertically go through the two strip-shaped plates, and the rollers can freely rotate between the two strip-shaped plates. A main shaft is connected to the middle parts of the strip-shaped plates and can drive the strip-shaped plates to rotate. When the main shaft rotates in a forward direction, one roller is in contact with the button and presses the button into a casing. When the main shaft rotates in a reverse direction, the button is released and reset to extend out of the casing. A telescopic rod, a mobile phone with the support of an external camera and a camera capable of shooting a display panel on the casing are also included. The camera is fixed to the lower right corner of the casing through a universal hose and is connected to the mobile phone. The top end of the telescopic rod is connected with the clamp type meter. The equipment has the advantages of convenience in use, high detection efficiency, and high safety and reliability.
