a limiting block is arranged in the limiting cavity in a sliding manner, a limiting connecting rod is fixedly arranged at one end, far away from the inner cavity, of the limiting block, and the limiting connecting rod extends into the operating groove in a sliding manner and is fixedly connected with the pull ring;
and a second spring is sleeved on the limiting connecting rod in the limiting cavity.
7. The aerial insulated cable mounting and supporting device as claimed in claim 6, wherein one end of the movable block, which is far away from the supporting rod, is provided with a second conical surface, and one end of the movable block, which is close to the supporting rod, is provided with an elastic pad;
one end of the limiting block, which is far away from the limiting connecting rod, is provided with an inclined surface which can be abutted and matched with the second conical surface;
the second spring is used for elastically supporting the limiting block;
when no external force exists, the pull ring is elastically supported at one end, close to the limiting cavity, of the operation groove under the action of the elastic force of the second spring, and the inclined plane of the limiting block is located in the inner cavity.
8. The aerial insulated cable mounting and supporting device according to claim 7, wherein when the arc-shaped supporting plate does not bear a cable, under the elastic force of the first spring, the elastic pad elastically abuts against one end part of the inner cavity body close to the arc-shaped supporting plate, and at the moment, the inclined surface of the limiting block abuts against the second conical surface of the movable block;
when the arc-shaped supporting plate bears the cable, the movable block is positioned on one side of the limiting block, which is far away from the arc-shaped supporting plate, and under the elastic force of the second spring, the limiting block extends out of the limiting cavity and limits the movable block;
when the elastic pad and one side of the limiting block far away from the arc-shaped supporting plate are abutted, the distance between the ends, far away from the connecting rod, of the two cable limiting plates is smaller than the minimum width of the cable.
9. The overhead insulated cable mounting support assembly of any one of claims 5-8, wherein the direction-adjusting support assembly comprises a base, a connecting seat, and a bolt;
the outer side of the base is provided with a fixing hole;
the middle part of the base is provided with a slot for inserting a support cylinder, one end of the support cylinder, which is far away from the arc-shaped supporting plate, is provided with a first conical surface, the lower part of the slot is provided with a third conical surface which can be matched with the first conical surface, the third conical surface is circumferentially provided with a plurality of convex edges, and the first conical surface is circumferentially provided with a plurality of grooves which can be matched with the convex edges;
when the first conical surface and the third conical surface are in butt fit, the convex edge and the groove are in butt fit at the same time;
one end of the support cylinder, which is far away from the arc-shaped supporting plate, is provided with a connecting seat;
the base is connected with a bolt in a threaded manner, and one end of the bolt is rotatably connected with the connecting seat.
