Through the arrangement of the third spring 212, the positions of the first engaging block 204 and the second engaging block 206 are separated, preventing the first engaging block 204 and the second engaging block 206 from fitting tightly, resulting in the first locking block 208 being unable to limit the second engaging block 206;

[0031] Refer to Figure 2 and Figure 3 , a second limiting groove 219 is provided at the top of the inner wall of the first moving groove 215. A second limiting block 220 is fixedly connected to the top of the first moving block 202. The surface of the second limiting block 220 is movably connected to the inner wall of the second limiting groove 219. A first limiting groove 218 is provided on one side of the inner wall of the third moving groove 216. A first limiting block 217 is fixedly connected to the surface of the first locking block 208. The surface of the first limiting block 217 is movably connected to the inner wall of the first limiting groove 218. Through the arrangement of the second limiting groove 219, when the first moving rod 201 moves, it can only move through the space inside the second limiting groove 219 by the second limiting block 220, preventing the force of the third moving block 213 contacting the second moving groove 203 from increasing when the first moving block 202 goes too deep, resulting in the connection between the first moving block 202 and the third moving block 213 becoming loose or even falling off;

[0032] Refer to Figure 2 and Figure 5, a sealing groove 16 is formed inside the engaging groove 304. A sealing ring 10 is movably connected inside the sealing groove 16. The bottom of the sealing ring 10 is fixedly connected to the top of the power adapter body 1. The inner side of the sealing ring 10 is fixedly connected to the bottom surface of the connecting block 13. Through the arrangement of the sealing groove 16, after the connector body 301 is inserted into the connecting block 13, the sealing ring 10 can enter the inside of the connector body 301. Through the fitting of the sealing ring 10 and the sealing groove 16, the connection between the connector body 301 and the connecting block 13 is more fitting, preventing water from entering the gap and causing a short circuit;

[0033] Refer to Figure 2 and Figure 6 , a protective ring 7 is fixedly connected to the top of the connecting block 13. The protective ring 7 is located on the surface of the first connecting wire 11. A positioning groove 15 is formed inside the connector body 301. The positioning groove 15 is located above the engaging groove 304 and is communicated with the engaging groove 304. The number of the positioning grooves 15 is two. A limiting ring 14 is fixedly connected inside the positioning groove 15. The bottom of the inner wall of the limiting ring 14 is inserted and connected to the first connecting wire 11. The inner wall of the limiting ring 14 is fixedly connected with a second connecting wire 12. The top of the second connecting wire 12 is located inside the connector body 301. The top of the second connecting wire 12 is fixedly connected with a plug pin 5. The plug pin 5 penetrates through the inside of the connector body 301 and extends to the top of the connector body 301. The inner wall of the protective ring 7 is movably connected with the surface of the limiting ring 14. The top of the first connecting wire 11 is movably connected with the bottom of the second connecting wire 12. Through the arrangement of the protective ring 7, the first connecting wire 11 is not exposed outside, preventing the risk of electric leakage. Through the arrangement of the limiting ring 14, the position of the first connecting wire 11 is more stable after being connected to the second connecting wire 12, preventing the first connecting wire 11 and the second connecting wire 12 from separating due to loosening and causing a short circuit;

[0034] Refer to Figure 4 , a second spring 209 is fixedly connected to the top of the fixing plate 211. The top of the second spring 209 is fixedly connected to the bottom of the first clamping block 208. The second spring 209 is located on the surface of the second moving block 210 and is movably connected with the second moving block 210. Through the arrangement of the second spring 209, the first clamping block 208 provides a certain elastic force after being forced to move inward, and can be bounced back to the initial position when the first clamping block 208 is no longer stressed.

[0035] Working principle: When it is necessary to remove and replace the connector body 301, first press the first moving rod 201 to move inward. The first moving rod 201 drives the first moving block 202 to move inward. Subsequently, the first moving block 202 drives the third moving block 213 to move inward, and the third moving block 213 drives the fourth moving block 214 to move inward. At the same time, the first moving rod 201 drives the second moving rod 205 to move inward, and the second moving rod 205 drives the second engaging block 206 to move inward. Subsequently, when the second engaging block 206 passes by the first engaging block 208, the first engaging block 208 is pushed downward by the extrusion of the second engaging block 206, and the second spring 209 is compressed and deformed. Subsequently, the second engaging block 206 moves to one side of the first engaging block 208. After that, the first engaging block 208 moves upward due to the elastic force of the second spring 209 and blocks the position of the second engaging block 206, making the fourth moving block 214 unable to move outward. When replacement is complete and fixation is required, first press the first moving rod 201 again. The first moving rod 201 drives the first engaging block 204 to move inward and pass by the first engaging block 208, and drives the second engaging block 206 to move inward through the second moving rod 205. Subsequently, due to the elastic force of the first spring 207, the second engaging block 206 moves outward. Due to the inclined surface setting of the first engaging block 204, the first engaging block 208 moves downward. The first engaging block 204 is slowed down by the resistance caused by the first engaging block 208 during outward movement and fits with the second engaging block 206. Subsequently, the second engaging block 206 moves outward by fitting with the first engaging block 204. The second engaging block 206 drives the second moving rod 205 to move outward. After that, the second moving rod 205 drives the first moving rod 201 to move outward. The first moving rod 201 drives the first moving block 202 to move outward. Then the first moving block 202 drives the third moving block 213 to move outward, and the third moving block 213 drives the fourth moving block 214 to move outward. The fourth moving block 214 moves into the inside of the insertion hole 302 to fix the positions of the power adapter body 1, the connecting block 13, and the connector body 301.
