As a further improvement, the anti-falling chain is inserted into one of the two threading holes and then drawn out from the other threading hole to form an annular ring, and the annular ring is sleeved on the lamp pole and is fixedly connected with the lamp pole through a locking piece. Inject and take out through preventing weighing down the chain, form the annular ring to fixed by the retaining member, can overlap and establish simple structure, convenient operation on the lamp pole.

As a further improvement of the utility model, the anti-falling chain is formed by twisting a plurality of steel wire ropes.

Compared with the prior art, the utility model has the advantages of simple structure, reasonable in design, the suitability is strong, links to each other with lamps and lanterns through the one end of preventing weighing down the chain, and the other end passes through tool to lock fixed connection with the lamp pole, can avoid receiving the influence of lamp pole appearance effectively to reach the connection protection between suitable lamps and lanterns and the multiple lamp pole in term. The lamp and the lamp rod are connected through the action of the fastener, so that the lamp and the lamp rod are firmly connected, and the lamp rod are used as a first fixing safety measure; along with the time, lamps and lanterns can produce the corrosion under the environment that the wind blows and drenches, if serious, influence the inner structure of lamps and lanterns to probably produce the risk of falling, through preventing weighing down the setting of chain, its one end is connected with the fixing base of lamps and lanterns, the other end passes through tool to lock fixed connection with the lamp pole, no matter what shape of appearance structure of lamp pole, all can connect through preventing weighing down the chain, and the suitability is strong, and this is as the insurance measure of second way, and this dual protection measure can prevent effectively that lamps and lanterns from producing the risk of falling, protects the safety of pedestrian and vehicle.
