After the circuit board 14 is detected, the detection result will be displayed on the display panel 17, which is convenient for users to quickly observe and improve the detection efficiency.

[0033] Example 2

[0034] The UPS maintenance circuit on-off detection pen is provided with a recovery structure, which can retract the probe 3 into the interior of the housing 1 by controlling the moving plate 7 to avoid damage to the probe 3, specifically:

[0035] The upper end of the shell 1 is slidably penetrated by a probe 3, the outer surface of the cover 2 is connected to the shell 1 by a connecting belt, and a recovery structure is arranged inside the shell 1, which can retract the probe 3 into the shell 1 by controlling the movable plate 7, and the recovery structure includes a fixed plate 4, a limited position frame 10 is fixedly installed on the upper surface of the fixed plate 4, an expansion bag 9 is installed on the inner wall surface of the limited frame 10, and the middle of the expansion bag 9 is slidably penetrated by the probe 3, a guide rod 5 is fixedly installed on the lower surface of the fixed plate 4, and a slide groove 6 is installed on the inner side surface of the guide rod 5, and the slide groove 6 is slidably connected to the movable plate 7, and the lower end of the guide rod 5 is fixedly connected to the circuit board 14, and the circuit board 14 is fixedly installed on the inner wall surface of the shell 1, and the movable plate 7 is slidably connected to the movable plate 7. The upper surface of the plate 7 is fixedly connected to the lower end of the probe 3, the front end of the movable plate 7 slides through the front surface of the shell 1, and a card block 8 is fixedly installed on the outer surface of the shell 1, and a push plate 13 is correspondingly arranged above the movable plate 7, and an air bag 11 is installed on the lower surface of the convex plate on the inner wall surface of the shell 1, and the air bag 11 is connected with the expansion bag 9 through the trachea, a card block 2 12 is installed on the outer surface of the shell 1, and a magnet is installed on the lower surface of the card block 2 12, the front end upper surface of the push plate 13 corresponds to the card block 2 12, and the rear end upper surface of the card block 2 12 corresponds to the air bag 11, and a groove is arranged on the upper surface of the movable plate 7, and the groove corresponds to the push plate 13, and the card block 2 12 is located above the card block 1 8;

[0036] When the UPS maintenance circuit continuity detection pen is not in use, the probe 3 can be retracted into the housing 1. Figure 1As shown, since the front end of the push plate 13 slides through the front surface of the housing 1, the push plate 13 is first pushed downward so that the push plate 13 and the card block 12 installed on the outer surface of the housing 1 lose magnetic attraction, as shown in FIG. Figure 4 As shown, since the other end of the push plate 13 compresses the airbag 11 on the lower surface of the inner wall surface pattern of the shell 1, the push plate 13 will release and squeeze the airbag 11 when it moves downward, so that the airbag 11 will expand naturally, and then the airbag 11 will suck the airflow in the expansion bag 9 through the trachea, so that the expansion bag 9 installed on the inner wall surface of the limit frame 10 is relaxed, so that the probe 3 loses its clamping, and then the probe 3 can slide. At this time, the push plate 13 passes through the block 8 and will be embedded in the groove on the upper surface of the moving plate 7, and then the moving plate 7 will continue to be pushed downward. The circuit board 14 is fixedly mounted on the inner wall surface of the housing 1, and the lower end of the guide rod 5 is connected to the circuit board 14, so the guide rod 5 is fixed, so that the other end of the movable plate 7 slides in the slide groove 6 installed on the side surface of the guide rod 5. Since the probe 3 slides through the upper surface of the housing 1, and slides through the fixed plate 4 and is fixedly connected with the upper surface of the movable plate 7, the movable plate 7 will drive the probe 3 downward as a whole, so that the probe 3 returns to the inside of the housing 1 to avoid damage to the probe 3 when not in use, and then the cover 2 is reversed and buckled on the upper end of the housing 1;
