The electrical system is often associated with automation technology. The electrical system is a system composed of low-voltage power supply components, also known as "low-voltage distribution system" or "low-voltage distribution line". The current electrical system detection devices are generally equipped with a system detection host. The electrical system can be detected by connecting the electrical system equipment to the system detection host.

[0003] Patent document CN217846388U discloses a portable detection device for electrical systems, "including a detection device body, a system detection host, a heat dissipation control screw and heat dissipation blades, wherein the system detection host is fixedly connected to the middle position inside the detection device body, and the lower end of the system detection host is provided with heat dissipation blades, and the lower end of the heat dissipation blades is transmission-connected to a blade connection motor. The utility model uses a mobile support frame to control the rotation of the heat dissipation control screw inside the detection device body through a screw connection motor when dissipating heat at different positions inside the detection device, so that the screw connection nut threadedly connected to the outer side of the heat dissipation control screw moves, and the mobile support frame is driven to move at the lower end of the system heat dissipation host through the screw connection nut, so that the heat dissipation blades can dissipate heat to different positions inside the detection device, thereby achieving a heat dissipation effect for multiple areas inside the detection device."

[0004] However, in the above scheme, the detection connecting wires are arranged outside the detection device body and are prone to automatically drooping downward. When they are squeezed by external force, the contact area between the external setting becomes larger, which can easily cause large-scale deformation, damage, wear and breakage of the detection connecting wires. In addition, the detection connecting wires are long and numerous, and are prone to confusion when they are retracted and released. To avoid the detection connecting wires from getting tangled with each other, they need to be disassembled, which reduces work efficiency. Utility Model Content
