An inner cavity is arranged inside the limiting insertion rod 203. One end of a moving column 205 is fixedly connected to one side of the contact pressing plate 204. The other end of the moving column 205 extends into the inner cavity of the limiting insertion rod 203 and is in sliding fit with the limiting insertion rod 203. An inclined plane slider A 206 is fixedly connected to one end of the moving column 205;

[0052] An inclined plane slider B 207 is slidably connected in the inner cavity of the limiting insertion rod 203. The inclined plane of the inclined plane slider B 207 contacts the inclined plane of the inclined plane slider A 206. Through this technical solution, when the inclined plane slider A 206 moves, the inclined plane slider B 207 can be made to move by inclined plane extrusion;

[0053] A fixed cylinder 208 is fixedly connected in the inner cavity of the limiting insertion rod 203. A moving piston 210 is slidably connected in the inner cavity of the fixed cylinder 208. One end of a moving guide rod 211 is fixedly connected to one side wall of the moving piston 210. The other end of the moving guide rod 211 penetrates the inner cavity wall of the fixed cylinder 208 and extends outside the wall. One end of the moving guide rod 211 is fixedly connected to the inclined plane slider B 207. One end of a connecting spring 212 is fixedly connected to the side wall of the fixed cylinder 208. The other end of the connecting spring 212 is fixedly connected to the inclined plane slider B 207. Through this technical solution, the movement of the inclined plane slider B 207 can drive the moving guide rod 211 to move, and thus the movement of the moving guide rod 211 can push the moving piston 210 to move.

[0054] As a specific technical solution, please refer to Figure 7 、 Figure 8 and Figure 9 As shown, the quick-release unit includes a quick-release fixed seat 303, a limiting slide plate 304, a limiting locking pin 305, a limiting spring 306, a connecting rod 307 and a pressing handle 308. One end of the plug 301 is fixedly connected to a connecting cable 302. Quick-release fixed seats 303 are fixedly connected to both sides of the plug 301. Slots for cooperating with the limiting insertion rod 203 are provided on the quick-release fixed seats 303;

[0055] The interior of the quick-release fixing base 303 is provided with an inner cavity. A limit sliding plate 304 is slidably connected in the inner cavity of the quick-release fixing base 303. A limit locking pin 305 is fixedly connected to the side wall of the limit sliding plate 304. One end of the limit locking pin 305 extends into the slot of the quick-release fixing base 303. A limit spring 306 is fixedly connected to the other side of the limit sliding plate 304. One end of a connecting rod 307 is fixedly connected to the side wall of the limit sliding plate 304. The other end of the connecting rod 307 penetrates through the side wall of the inner cavity of the quick-release fixing base 303 and extends outside the wall. A pressing handle 308 is fixedly connected to one end of the connecting rod 307. An arc surface is provided on one side of the limit locking pin 305. Through this technical solution, when the plug-in module 3 is plugged and connected to the socket module 2, the limit insertion rod 203 will be inserted into the slot of the quick-release fixing base 303. At the same time, the arc surface 2032 contacts the arc surface of the limit locking pin 305, causing the limit locking pin 305 to retract. After being completely inserted, the limit locking pin 305 is inserted into the limit groove 2031 again through the rebound of the limit spring 306, playing an automatic locking function. When it needs to be disassembled, only need to manually pinch the pressing handles 308 on both sides. The pressing handles 308 can drive the limit locking pin 305 to move, so that the limit locking pin 305 is separated from the limit groove 2031, and the unlocking function can be realized, which is convenient for removal;

[0056] When the limit locking pin 305 is inserted into the limit groove 2031, the limit locking pin 305 moves due to the action of the limit spring 306, and will automatically contact and press the contact pressing plate 204, causing the contact pressing plate 204 to move. The movement of the contact pressing plate 204 can drive the inclined plane slider A206 to move, and then drive the inclined plane slider B207 to move, thereby pushing the moving guide rod 211 to move, and then automatically driving the moving piston 210 to move, so that the gas in the inner cavity of the fixed cylinder 208 can be pushed into the inner cavity of the sealing rubber ring 202, causing the sealing rubber ring 202 to expand, playing an effect of compensating for the gap, effectively avoiding the intrusion of external dust, foreign matters, moisture, etc. At the same time, the pre-tightening elasticity of the limit spring 306 can make the moving piston 210 continuously apply a certain force, so as to play a certain self-adaptive function when the gap changes due to temperature changes;

[0057] The waterproof ring 309 is fixedly arranged at the side wall position of the connecting cable 302. The waterproof ring 309 includes a non-woven fabric outer sleeve 3092 and water-absorbing silica gel particles 3093. The inside of the non-woven fabric outer sleeve 3092 is filled with water-absorbing silica gel particles 3093. Through this technical solution, through the setting of the waterproof ring 309, when water enters at the gap, the water-absorbing silica gel particles 3093 can play an automatic water-absorbing role, further reducing the risk caused by water intrusion;

[0058] An annular groove is provided at the side wall of the movable socket 201. A sealing rubber ring 202 is fitted and fixed in the annular groove of the socket 201. One end of a connecting pipe 209 is fixedly connected in the inner cavity of the sealing rubber ring 202, and the other end of the connecting pipe 209 extends into the inner cavity of the fixed cylinder 208 and is fixedly connected to the fixed cylinder 208.
