As shown in fig. 22, a guide sleeve 50 for guiding the first rack 49 is installed in the receptacle housing 2.

The adjusting block 53, the connecting block 45, the transmission rod 46, the second rack 47, the second gear 48, the first rack 49, the third gear 51 and the connecting rod 52 are designed to have the functions that in order to ensure better sealing performance, the third spring 16 and the fifth spring 23 designed in the invention have larger elastic coefficients, but when a plug is inserted, if the third spring 16 and the fifth spring 23 have larger elastic coefficients, the resistance of plug insertion is larger, and at the moment, in order to reduce the resistance of plug insertion, the first fixture block 17 and the second fixture block 24 are moved inwards through the connecting block 45, the transmission rod 46, the second rack 47, the second gear 48, the first rack 49, the third gear 51 and the connecting rod 52 designed to reduce the resistance of plug insertion.

In the invention, after the plug is inserted, in order to ensure the sealing property, the adjusting block 53 can be adjusted again, so that the first clamping block 17 and the second clamping block move inwards to increase the sealing property.

The specific working process is as follows: when the socket designed by the invention is used, when a plug is inserted, the plug is inserted from the second square socket 28 formed on the waterproof rubber layer 11, then inserted into the inner side of the sliding shell 12 from the first square socket 35 formed on the upper end surface of the sliding shell 12, and finally inserted into the third square socket 29 formed on the sliding column 15 arranged on the inner side of the sliding shell 12; when the lower end of the plug is completely inserted into the corresponding third square socket 29, the lower end of the plug presses the trigger inclined plane 37 on the trigger block 19, the trigger block 19 is extruded and moves inwards, the trigger block 19 moves inwards to drive the connecting rod 26 to move, the connecting rod 26 moves to drive the first gear 27 to rotate, the first gear 27 rotates to drive the limiting rod 25 to move, and the limiting rod 25 is in contact with the sliding fit between the sliding column 15 and the sliding shell 12; when the plug presses the trigger inclined plane 37 on the trigger block 19, the trigger block 19 is extruded and moved inwards, the trigger block 19 moves inwards to drive the connecting rod 26 to move, the connecting rod 26 moves to drive the first gear 27 to rotate, and the first gear 27 rotates to drive the limiting rod 25 to move, so that the limiting rod 25 is in contact with the sliding fit between the sliding column 15 and the sliding shell 12.

When the plug is pulled out, the plug can pull the sliding column 15 to move upwards through the first fixture block 17, the sliding column 15 drives the inserting sheet 20 on the lower side to move upwards, but the inserting sheet 20 is limited by the second fixture block 24 at the moment, so that the inserting sheet 20 moves upwards and drives the sliding shell 12 to move upwards through the second fixture block 24, the sliding shell 12 moves upwards to a certain extent, water can be prevented from permeating into the sliding shell 12, and meanwhile, because the sealing ring 9 is arranged between the sliding shell 12 and the socket shell 2, water cannot flow into the edge of the sliding shell 12; after the inserting sheet 20 is moved to be separated from the lower electrified inserting sheet 3, the plug is powered off, and the electric shock phenomenon cannot occur; after the sliding shell 12 moves up to the limit state, that is, after the first spring 10 is stretched to the limit state, under the condition that the plug is pulled continuously, because the elastic coefficient of the fifth spring 23 is smaller than the elastic coefficient of the third spring 16, the plug 20 will gradually disengage from the second latch 24 first, after the plug 20 disengages from the second latch 24, the plug will drive the sliding column 15 to move up relative to the sliding shell 12 through the first latch 17, after the sliding column 15 moves up to the topmost end of the sliding shell 12, the sliding column 15 stops moving up, and when the plug is pulled continuously, the first latch 17 will disengage from the plug, and the plug is pulled out.

When a plug is inserted, if the elastic coefficients of the third spring 16 and the fifth spring 23 are large, the resistance of the plug to be inserted is large, and at this time, in order to reduce the resistance of the plug to be inserted, the connecting rod 52 can be adjusted to move, the connecting rod 52 moves to drive the first rack 49 mounted thereon to move, the first rack 49 moves to drive the second gear 48 to rotate, the second gear 48 rotates to drive the third gear 51 to rotate, the third gear 51 rotates to drive the second rack 47 to move, the second rack 47 moves to drive the transmission rod 46 to move, the transmission rod 46 moves to drive the two connecting blocks 45 to move, the two connecting blocks 45 move to pull the first fixture block 17 and the second fixture block 24, so that the first fixture block 17 and the second fixture block 24 move backwards, and the resistance of the first fixture block 17 and the second fixture block 24 in the plug inserting process is reduced; the plug is convenient to insert.
