As shown in fig. 3, in order to seal the common plug 2 and the connection wire 4, the inner wall of the flexible ring 13 is provided with a first outlet 15 and a second outlet 16, and the first outlet 15 and the second outlet 16 cooperate to form a through hole sealed with the outer peripheral surface of the connection wire 4. First outlet 15 and second outlet 16 are used for stepping down for connecting wire 4, form sealed cooperation with the outer peripheral face of connecting wire 4 simultaneously, so, can effectively improve 8 closed sealing performance in flexible pipe 8 free end port, improve the sealing performance between 8 ports in flexible pipe and the connecting wire 4 simultaneously to ensure holistic waterproof performance.

The fastener 12 comprises a first buckle 21 arranged at the end part of the first clamping plate 10 and a second buckle 22 arranged at the end part of the second clamping plate 11, and the first buckle 21 is in snap fit with the second buckle 22. The first buckle 21 and the second buckle 22 can be quickly clamped and disassembled, and the use is more convenient.

As shown in fig. 4, when in use, the folding tube 7 is firstly in a folded state (as shown in fig. 2), at this time, the free end port of the flexible tube 8 is closer to the common socket 3, so that the common plug 2 can be conveniently plugged into the common plug 3, after plugging, the folding tube 7 is stretched to a state shown in fig. 4, and when stretched, the folding tube 7 can be stretched into a straight tube shape or a bent tube shape according to the direction of the connecting wire 4 on the common plug 2; then, the first clamping plate 10 and the second clamping plate 11 are folded in half, the first clamping plate 10 and the second clamping plate 11 move towards each other, pressure is applied from the annular groove 14 outside the flexible ring 13 to seal the opening of the flexible ring 13, the connecting wire 4 is connected out from a through opening formed by matching the first outlet 15 and the second outlet 16, and meanwhile, the peripheral surface of the connecting wire 4 forms a seal with the through opening; then, the ends of the first clamping plate 10 and the second clamping plate 11 are connected together by clamping a first clamping buckle 21 and a second clamping buckle 22 (as shown in fig. 3), so that a stable sealing state is formed; in the scheme, the protection grade of the electromagnetic conversion socket is not less than IP65, and the protection grade of the waterproof point adaptor is not less than IP 54.

As an improvement of the present solution, on the design idea of the present solution, a plurality of common sockets 3 may be arranged on the electromagnetic conversion plug 1 or a plurality of jacks may be arranged on one common socket 3, and a plurality of first outlets 15 and second outlets 16 for connecting the connecting wires 4 are correspondingly arranged on the flexible ring 13, so that a plurality of common plugs 2 may be plugged in, and the connecting wires 4 of the common plugs 2 may be sealed by pressing when the flexible ring 13 is folded.

It is obvious that the above embodiments of the present invention are only examples for clearly illustrating the technical solutions of the present invention, and are not limitations to the specific embodiments of the present invention. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
