External line testing device for electrical equipment and application method thereof

Abstract

The invention discloses an external line testing device for electrical equipment. The external line testing device comprises an engine body, a display screen is mounted on the front surface of the engine body, a network cable jack and a switch are arranged at the rear surface of the engine body, a protection mechanism is arranged at the front surface of the engine body, and comprises a protectionplate, a frame, necks, a spring and a fixing groove, the frame is fixed to the outer side of the display screen, the necks are symmetrically formed in the upper portion of the inner side face of the frame, one end of the protection plate is inlaid into the frame, the other end of the protection plate extends out of the frame, and the fixing groove is formed in the outer side face of the inlaid endof the protection plate. The invention further discloses an application method of the external line testing device for electrical equipment. By means of the designed protection mechanism, the displayscreen can be protected through matching of the protection plate and the frame; when the display screen is used, the protection plate can be conveniently limited; and through designed folding and unfolding mechanisms, folding and unfolding of a handle are facilitated, and the space occupied when the handle is exposed outside is saved.
