[0030] Working principle: the connecting seat 2 is connected to the inside of the first connecting groove 101, then the rotary cap 9 is rotated, the rotary cap 9 drives the worm 8 to rotate, because the worm 8 is engaged with the worm wheel 7, the rotation of the worm 8 will make the worm wheel 7 rotate, so that the worm wheel 7 drives the bidirectional threaded rod 6 to rotate, when the bidirectional threaded rod 6 rotates, because the outer surface of the bidirectional threaded rod 6 is movably sleeved with the moving plate 10, and the moving plate 10 slides in the sliding groove 11 in the inside of the cavity 5, the rotation of the bidirectional threaded rod 6 will make the moving plate 10 produce linear displacement in the sliding groove 11, the first limiting rod 12 fixedly connected to one side of the moving plate 10 will move along with the linear displacement of the moving plate 10, so that the two first limiting rods 12 relatively move and gradually approach the first limiting hole 4 on both sides of the connecting seat 2 and finally insert into the two first limiting holes 4, realizing the fixed connection of the connecting seat 2 and the base 1, at the same time, by pulling the pull ring 1409, the pull ring 1409 drives the pull rod 1407 to move, the pull rod 1407 drives the sliding plate 1405 to slide in the fixed shell 1404 against the elastic force of the return spring 1408, the sliding plate 1405 drives the second limiting rod 1406 to move out of the second limiting hole 1403, at this time, the plug plate 1402 can be pulled out of the plug groove 1401, and then the protective shell 13 can be disassembled, so that the relay main body 3 can be conveniently overhauled, after the overhaul is completed, the plug plate 1402 is inserted into the plug groove 1401, the pull ring 1409 is loosened, the return spring 1408 pushes the sliding plate 1405, so that the second limiting rod 1406 is reinserted into the second limiting hole 1403, the installation of the protective shell 13 is completed, after the equipment connection of the upper end of the base 1 is completed, the base 1 is fixed by using bolts through the threaded holes 19, then the connecting line is connected to the inside of the connecting hole 17, so that the device can be normally used.

[0031] The above is only a preferred embodiment of the present application, and does not limit the present application in other forms. Any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields, but any simple modification, equivalent change and modification of the above embodiments according to the technical essence of the present application still belongs to the protection scope of the technical scheme of the present application.
