The portion of the open clamp 2 located above the transverse dividing slit 3 is fixed to the upper insulating rod 1 of the two adjacent insulating rod sections 1 via a press-locking member. When the press-locking member is in the unlocked state, a gap is left between the portion of the open clamp 2 located above the transverse dividing slit 3 and the upper insulating rod 1 of the two adjacent insulating rod sections 1, allowing the two adjacent insulating rod sections 1 to slide relative to each other. When the press-locking member is in the unlocked state, the two adjacent insulating rod sections 1 can slide relative to each other to achieve telescopic adjustment. When the press-locking member is in the locked state, the two adjacent insulating rod sections 1 can be locked together. Specifically, in this embodiment 1, the open clamp 2 is made of a metal material such as aluminum alloy, stainless steel, or a high-strength plastic material. The length of the transverse dividing slit 3 accounts for one-third of the circumference of the open clamp 2.
