[0002] The DC cables used to connect photovoltaic modules to combiner boxes in photovoltaic power stations are mostly two-core dual-parallel cables. During daily maintenance and repair, the cable current cannot be directly measured using a clamp-on ammeter. The two cables need to be split with a knife or other tools to detect the current of a single cable separately. During daily maintenance, the current detection work cannot be completed by carrying a clamp-on ammeter alone. However, in daily work, the detection work is often not completed due to forgetting to bring the tool or wasting time going back and forth to get the tool, which affects the cable maintenance efficiency.

[0006] Furthermore, a bracket is fixed in the blind hole, and the bracket divides the interior of the blind hole into a driving cavity and a telescopic cavity. The sliding seat and the fixed seat are both arranged in the telescopic cavity.

[0007] Furthermore, a driving hole connected to the driving cavity; the driving assembly includes a screw rotatably connected to the blind hole, a rotating shaft rotatably connected to the driving hole, and a driven bevel gear fixed on the screw, one end of the rotating shaft extends into the driving cavity and is connected to the active bevel gear, and the other end of the rotating shaft passes through the above-mentioned driving hole and is connected to a knob, an internal threaded hole is provided on the sliding seat opposite to the screw, and the active bevel gear is meshed with the driven bevel gear.

[0008] Furthermore, an avoidance hole is provided on the fixing seat directly facing the lead screw.

[0009] Furthermore, the knob is provided with a plurality of ridges, and the ridges are arranged perpendicular to the turning direction of the knob.

[0010] The beneficial effects of the utility model are:

[0011] In actual application, when in use, the driving component drives the sliding seat to slide along the blind hole, and the slider slides along the slide groove. At the same time, the blade on the fixed seat extends from the opening of the blind hole, and the two-core double-parallel structure cable can be split into single cables by the blade; the utility model does not need to carry additional tools during daily maintenance, and can also split the two-core double-parallel structure cable into single cables for clamp ammeter detection, which saves working time and improves the cable maintenance efficiency.
