A suspended cable support with earthquake-resistant function as claimed in claim 1, wherein: the inner wall fixedly connected with connecting plate (10) of highly fixed pipe (2), the lower extreme fixedly connected with buffer block (11) of connecting plate (10), buffer block (11) are located the upside of slide bar (5).
5. A suspended cable support with earthquake-resistant function as claimed in claim 1, wherein: and a sealing film is fixedly connected between the inner walls of the through holes (22).
6. A suspended cable support with earthquake-resistant function as claimed in claim 1, wherein: a limiting hole and a limiting rod are formed in one end, close to each other, of the fixing block (19), and the limiting hole and the limiting rod are arranged in a staggered mode.
7. A suspended cable holder with earthquake-proof function according to any one of claims 1-6, characterized in that: the using method comprises the following steps:
s1, a sliding limiting rod (7) at the outer end of the sliding rod (5) slows down the shaking of the inner wall of the strip-shaped sliding hole (6) through a main compression spring (8), the possibility that the cable is broken due to the shaking of natural factors is reduced, and the sliding fluency of the sliding rod (5) in the height fixing pipe (2) is improved through a ball (703);
s2, when the cable is short-circuited to generate a large amount of high temperature, the cable is cooled by heat through refrigerating fluid (18), insulating glue (21) in the storage tank covers the surface of the cable through a through hole (22), and current at the damaged part is isolated and repaired;
s3, the limiting connection frame (3) is further supported through the connection rope (4), the pressure sensor (24) sends out early warning by receiving a pair of pressure signals between the connection ropes (4), the cable is protected better, current is led into the fixed station (1) through the conductive fibers (23) inside the connection ropes (4), and voltage overstock is reduced.
