[0027] When the device is to be used for power detection, first open the detection pen body 1, then hold the detection pen body 1 to make the probe 3 contact with the object to be detected, so that power detection can be performed. After the detection is completed, close the detection pen body 1. When the probe 3 is to be replaced, first pull the push rod 23 forward to squeeze the card plate 6 to move outward, and the first elastic member 7 is compressed accordingly. At this time, the probe 3 can be removed and replaced, thus achieving the purpose of facilitating replacement. After the replacement is completed, push the push rod 23 backward to reset it, and the first elastic member 7 drives the card plate 6 to move inward, so that the probe 3 can be fixed. Example 2

[0028] Based on Example 1, see Figure 4 As shown, it also includes a first support seat 8. Two first support seats 8 symmetrically distributed up and down are fixedly connected to the upper part of the detection pen body 1. The first support seat 8 is connected to the second elastic member 11. The front end of the second elastic member 11 is connected to the mounting plate 9. The mounting plate 9 is fixedly connected to a sponge block 10 for wiping the probe 3. The sponge block 10 can move to wipe the probe 3.

[0029] When the probe 3 is inserted into the socket, the mounting plate 9 will be squeezed and the sponge block 10 will be moved backward, and the second elastic member 11 will be compressed accordingly, so that the sponge block 10 can wipe the probe 3, thereby achieving the purpose of automatic cleaning; when the probe 3 is taken out of the socket, the second elastic member 11 can drive the mounting plate 9 and the sponge block 10 to move forward and reset.

[0030] See also Figure 5 and Figure 6 As shown, it also includes a guide rail 12, the guide rail 12 is fixedly connected to the rear side of the detection pen body 1, a pressure plate 14 is slidably arranged in the guide rail 12, the pressure plate 14 is fixedly connected to the baffle 13 for blocking the battery, a slide rail 16 is fixedly connected to the left side of the top of the guide rail 12, a limit plate 17 for supporting the pressure plate 14 and the baffle 13 is slidably arranged in the slide rail 16, a third elastic member 15 is connected between the pressure plate 14 and the guide rail 12, the third elastic member 15 is located in the guide rail 12, and the baffle 13 is fixedly connected to a glass plate 22.

[0031] Initially, the third elastic member 15 is in a compressed state. When the battery needs to be replaced, the limit plate 17 is first pulled upward until it is disengaged from the baffle 13 and the pressure plate 14. At this time, the third elastic member 15 can drive the pressure plate 14 and the baffle 13 to move to the left. At this time, the battery can be replaced, thus achieving the purpose of facilitating battery replacement. After the replacement is completed, the baffle 13 is pushed to the right to drive the pressure plate 14 to move to the right and reset. The third elastic member 15 is compressed accordingly, and then the limit plate 17 is moved downward so that it can push the pressure plate 14 and the baffle 13 again. Under the action of the glass plate 22, it is convenient to check whether there is a battery installed in the detection pen body 1.

[0032] See also Figure 7 As shown, it also includes a second support seat 1701, the second support seat 1701 is fixedly connected to the upper part of the detection pen body 1, the support seat 1701 is located below the probe 3, the second support seat 1701 is rotatably provided with a cutting knife 18, the second support seat 1701 is fixedly connected to a protective cover 19, the cutting knife 18 is located in the protective cover 19, the protective cover 19 is slidably provided with a limit block 20 for limiting the cutting knife 18, the protective cover 19 is fixedly connected with magnets 21 symmetrically distributed on the left and right, and the magnets 21 are used to attract the limit block 20.

[0033] When it is necessary to perform an electrical inspection on the wire, first pull the limit block 20 downward to disengage the cutting knife 18, and then rotate the cutting knife 18 upward. At this time, the cutting knife 18 can be used to strip the wire, thereby achieving the purpose of facilitating electrical inspection on the wire. When the cutting knife 18 is not needed, the cutting knife 18 is turned downward into the protective cover 19, and then the limit block 20 is pushed upward to reset. In this way, the cutting knife 18 can be limited to prevent the cutting knife 18 from easily disengaging from the protective cover 19. Under the action of the magnet 21, the limit block 20 can be sucked to prevent the limit block 20 from sliding downward.
