[0018] The utility model will be further described in detail in combination with the drawings and embodiments:

[0019] As Figures 1-4The utility model provides an exchangeable plug power adapter, including adapter shell 1 and modular plug 2, one end of adapter shell 1 is provided with clamping groove 4, the inner wall of clamping groove 4 is rotatably connected with plug base 5, one end of modular plug 2 is connected with the plug slot connecting seat 3 matched with clamping groove 4, plug slot connecting seat 3 is used in cooperation with plug base 5, one end of adapter shell 1 is connected with interface 6 away from plug base 5, and the inner wall of adapter shell 1 is integrally formed with mounting column 7, the inner chamber of mounting column 7 is through to adapter shell 1, and the inner chamber of mounting column 7 is inserted with movable rod 8, one end of movable rod 8 is marked with the thread matched with screw hole 12, and one end of movable rod 8 is marked with the thread matched with screw hole 12.

[0020] The utility model provides an exchangeable plug power adapter, including adapter shell 1 and modular plug 2, one end of adapter shell 1 is provided with clamping groove 4, the inner wall of clamping groove 4 is rotatably connected with plug base 5, one end of modular plug 2 is connected with the plug slot connecting seat 3 matched with clamping groove 4, plug slot connecting seat 3 is used in cooperation with plug base 5, one end of adapter shell 1 is connected with interface 6 away from plug base 5, and the inner wall of adapter shell 1 is integrally formed with mounting column 7, the inner chamber of mounting column 7 is through to adapter shell 1, and the inner chamber of mounting column 7 is inserted with movable rod 8, one end of movable rod 8 is marked with the thread matched with screw hole 12, and one end of movable rod 8 is marked with the thread matched with screw hole 12,

[0021] In the scheme, the modular plug 2 is a replaceable plug, and the structures of the plug slots connected to the plug slot connecting seats 3 of different countries and regions are consistent. When in use, a user inserts the plug slot connecting seat 3 into the clamping groove 4, connects the plug slot connecting seat 3 with the plug base 5, and then connects the modular plug 2 with a socket, so that the current can be converted through the adapter. The user connects a transmission line with the interface 6, and can charge the equipment through the transmission line. After the modular plug 2 is connected with the adapter shell 1, the screw hole 12 on the modular plug 2 is aligned with the movable rod 8. At this time, the user rotates the movable rod 8 and pushes the end of the movable rod 8 marked with the thread into the screw hole 12, so that the movable rod 8 is screwed with the screw hole 12, and the modular plug 2 is fixed through the movable rod 8, so that the modular plug 2 is fixed on the adapter shell 1 and cannot fall off. The modular plug 2 is effectively prevented from loosening in use. The mounting column 7 is arranged in the inner chamber of the adapter shell 1, occupies a small space, and does not affect the arrangement of the components in the adapter shell 1.

[0022] The outer end of the movable rod 8 is connected with a limiting block 10, the limiting block 10 is matched with the shape of the inner chamber of the mounting column 7, a spring 11 is sleeved on the outer end of the movable rod 8, and the two ends of the spring 11 are respectively abutted with the inner wall of the mounting column 7 and the limiting block 10. The surface of the end of the movable rod 8 close to the plug base 5 is flush with the surface of the adapter shell 1.

[0023] In the scheme, through the setting of the spring 11, it can be ensured that the threaded end of the movable rod 8 does not protrude outside the adapter shell 1 without external force, thereby avoiding the interference of the movable rod 8 to the installation of the modular plug 2, and the limiting block 10 plays a limiting role on the movable rod 8, so that it will not fall out of the mounting column 7, and when the modular plug 2 is installed, the user pushes the movable rod 8, which can cause the spring 11 to be extruded, thereby forcing the end of the movable rod 8 to be connected with the threaded hole 12.

[0024] The end of the movable rod 8 away from the pin base 5 extends to the outside of the adapter shell 1 and is connected with the knob 9.

[0025] The setting of the knob 9 in the scheme facilitates the user to rotate the movable rod 8.

[0026] The specific implementation process is as follows:

[0027] In use, the user first inserts the socket connecting seat 3 into the clamping groove 4, so that the socket connecting seat 3 is connected with the pin base 5, and then connects the modular plug 2 with the socket, so that the current can be converted through the adapter. The user then connects the transmission line with the interface 6, so that the device can be charged through the transmission line. When the modular plug 2 is connected with the adapter shell 1, the threaded hole 12 on the modular plug 2 will be aligned with the movable rod 8. At this time, the user rotates the movable rod 8 and pushes the threaded end of the movable rod 8 into the threaded hole 12, while the limiting block 10 extrudes the spring 11, thereby making the movable rod 8 and the threaded hole 12 threadedly connected. Through the movable rod 8, the modular plug 2 is fixed, so that the modular plug 2 is fixed on the adapter shell 1 and cannot fall off.

[0028] The above is only an embodiment of the present application, and the specific technical solutions and / or characteristics of the scheme are not described in detail. It should be noted that for those skilled in the art, without departing from the technical solutions of the present application, a number of modifications and improvements can be made, which should also be considered as the protection scope of the present application. The protection scope of the present application should be subject to the content of its claims, and the specific implementation mode and the like in the specification can be used to explain the content of the claims.
