[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Embodiment 1

[0026] Reference Figure 1 - Figure 4 , a circuit safety detection device, comprising a terminal 1, an anode electric pen 2 and a cathode electric pen 3, and further comprising:

[0027] The electric pen assembly 4 is a component for directly testing the safety of the circuit; the electric pen assembly 4 includes a housing 6, and a pipe 7 is provided inside the housing 6. The function of the pipe 7 is to insert and install an insulating handle 8 inside, and then install a contact 9 for testing inside the insulating handle 8. The main purpose is to achieve integration without destroying the original structure of the electric pen. The insulating handle 8 is movably installed inside the pipe 7, and the contact 9 is inserted and inserted inside the insulating handle 8;

[0028] The marking component 5 includes an ink cartridge 10 installed on one side of the housing 6, and the interior of the ink cartridge 10 can be filled with dyes of different colors. A leather plug 11 is sealed and installed on one side of the ink cartridge 10, and the leather plug 11 is a sealing device; the interior of the ink cartridge 10 is filled with color dyes, and a conduit 12 is connected and installed on one side of the ink cartridge 10, and the dye is transported to the surface of the sponge 13 through the conduit 12, and then during the detection of the contact 9, the annular range around the detection part can be marked with the dye. The end of the conduit 12 is connected and installed with a sponge 13, and the sponge 13 is sleeved and installed on the surface of the housing 6, and the end of the sponge 13 extends out of the housing 6.

[0029] A circuit safety detection device, the electric pen assembly 4 also includes a leather wire 17 connected and installed on one side of the insulating handle 8, and the leather wire 17 is a cable for transmitting electrical signals to the inside of the terminal 1.

[0030] A circuit safety detection device, the end of the sheathed wire 17 is connected and installed on one side of the terminal 1.

[0031] A circuit safety detection device, a terminal 1 is provided with a display screen 18 on its surface, the terminal 1 is a commonly used multimeter terminal 1, a switch 19 and a knob 20 are used for an operation interface, and the display screen 18 is used to display the detection content. The switch 19 and the knob 20 are provided on both sides of the terminal 1, respectively.

[0032] A circuit safety detection device, in order to prevent the insulating handle 8 and the contact 9 from sliding during the detection process, we need to limit them: a screw hole 14 is opened on one side of the housing 6, and a screw plug 15 at the end of a nut 16 is manually controlled to be screwed into the screw hole 14 and abut against the surface of the insulating handle 8, thereby achieving the positioning effect of the insulating handle 8 and the contact 9. A screw plug 15 is screwed into the screw hole 14, and a nut 16 is provided at the end of the screw plug 15, and the screw plug 15 is abutted against the side of the insulating handle 8.

[0033] A circuit safety detection device, the insulating handle 8 and the pipe 7 are both square in structure. In order to prevent the contact 9 from rotating arbitrarily during the detection process, the movable parts, the insulating handle 8 and the adapter structure - the pipe 7 are all set to be square, which can limit the rotation effect of the end contact 9.

[0034] Working principle:

[0035] In the actual use of the device, in order to avoid the technical problem that the electric pen cannot leave a detection trace after detection in the prior art, which leads to the inability to record the detection effect and even causes secondary detection, the electric pen component 4 and the marking component 5 are specifically proposed:

[0036] In order to protect the integrity of the electric pen assembly 4, the device is provided with a pipe 7 inside the housing 6, and the contact 9 of the electric pen is slidably installed inside the pipe 7 through the square insulating handle 8, thereby realizing the position adjustment of the end contact 9. The ink box 10 installed on the side of the housing 6 allows the inside to store dyes of different colors, thereby providing different recognition for each mark. The ink box 10 transports fuels of different colors to the surface of the sponge 13 through the conduit 12. The structure of the sponge 13 is tubular, so when the contact 9 contacts the circuit, the tubular sponge 13 will be squeezed around the detection part and form a ring-shaped mark. In the process of the same detection, the same color fuel is used in the cathode and the anode, which can increase the recognition of different detections and avoid the technical problems of multiple detections in the prior art. The above is only a preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field within the technical scope disclosed by the utility model, according to the technical solution and the utility model concept of the utility model, shall be covered within the protection scope of the utility model.
