Description

Technical Field

[0001] This utility model relates to the field of electronic engineering testing technology, and in particular to a rapid circuit fault detection device. Background Technology

[0002] Common circuit faults include open circuits, short circuits, overloads, poor contact, and incorrect connections. An open circuit will prevent electrical appliances from working, while a short circuit will blow a fuse, causing the entire lighting circuit to lose power, and in severe cases, it can burn out the wiring and cause a fire. Circuit fault detection devices are used to quickly and accurately locate fault points in circuits.

[0003] Existing circuit fault detection devices are troublesome to carry and use because the connecting wires are long and tend to become tangled and piled up. In addition, the crossing and tangling of the wires increases the complexity of the detection and affects the normal use of the detection head. Utility Model Content

By manually turning the handwheel to drive the rotating rod to rotate, and using the meshing transmission of the worm gear and worm wheel, the winding roller can rotate around the rotating shaft as the axis, which can wind the first connecting wire into the mounting box, effectively avoiding the wire from being scattered and piled up, making the device easy to carry and use. Its winding structure is simple and easy to operate.

[0010] In at least some embodiments, the right end of the rotating rod is provided with a handwheel, and the rotating rod is provided with a worm gear, which is meshed with a worm wheel.

[0011] In at least some embodiments, a support frame is provided on one side of the limiting sleeve, two sliding sleeves are provided on the support frame, and two limiting tubes are provided on the limiting sleeve, with the two limiting tubes distributed symmetrically.

[0012] In at least some embodiments, the right end of the adjusting frame is provided with a lifting block, which is in contact with the push block.
