The bottom of the moving rod 10 is fixedly connected to a spring 12, and the bottom end of the spring 12 is fixedly connected to the bottom of the groove 9. A fixed block 13 is fixedly sleeved outside the moving rod 10, and the fixed block 13 is located at the top of the connecting rod 8. The top of the fixed block 13 is fixedly connected to an annular pad 14, and the annular pad 14 contacts the inner wall of the top of the housing 2;

[0038] The moving block 7 is slidably connected to the T-shaped slot 5, the connecting rod 8 is slidably connected to the T-shaped slot 5, the moving rod 10 is slidably connected to the groove 9 and the through slot 6, the power cord body 1 is slidably connected to the rotating shaft 3, and the spring 12 is in a compressed state;

[0039] In this embodiment, the pressing block 11 is pressed downward, so that the moving rod 10 can be moved downward, and the annular pad 14 is no longer in contact with the housing 2. Then the pressing block 11 is pushed, so that the moving rod 10, the connecting rod 8 and other components can be moved to the middle of the housing 2. At the same time, the power cord body 1 can be pulled to lengthen the power cord body 1.

[0040] In order to facilitate the movement of the pressing block 11, the device is implemented by the following technical solution: a plurality of protrusions 15 are fixedly connected to the top of the pressing block 11, and the protrusions 15 can facilitate the movement of the pressing block 11;

[0041] In order to achieve the purpose of good friction, the device adopts the following technical solutions: the annular pad 14 is made of rubber material, and the annular pad 14 of rubber material has good friction and can prevent the moving rod 10 from moving randomly;

[0042] Among them, in order to achieve the purpose of avoiding the disorder of the power cord body 1, the present device adopts the following technical solution: the outer fixed sleeve of the connecting rod 8 is provided with two limit blocks 16, the two limit blocks 16 are respectively in contact with the top and bottom of the power cord body 1, the limit blocks 16 are slidably connected with the power cord body 1, and the limit blocks 16 can limit the power cord body 1, so as to avoid the disorder of the power cord body 1;

[0043] Among them, in order to achieve the purpose of protecting the power cord body 1, the device adopts the following technical solutions: sleeve 1 17 and sleeve 2 18 are fixedly embedded on both sides of the shell 2, the power cord body 1 passes through the sleeve 1 17 and the sleeve 2 18, the power cord body 1 is slidably connected with the sleeve 1 17, the power cord body 1 is fixedly connected with the sleeve 2 18, the sleeve 1 17 and the sleeve 2 18 are both made of rubber material, and the design of the sleeve 1 17 and the sleeve 2 18 can protect the power cord body 1, and can avoid bending and breaking at the position in contact with the shell 2;

[0044] Among them, in order to achieve the purpose of increasing the insulation capacity of the power cord body 1, the present device is implemented by the following technical scheme: the power cord body 1 includes a wire core 19, a shielding sleeve 20 and an insulating sleeve 21, the insulating sleeve 21 is fixedly sleeved on the outside of the shielding sleeve 20, and the shielding sleeve 20 is fixedly sleeved on the outside of the wire core 19. The shielding sleeve 20 can reduce the interference and radiation to the power cord body 1. At the same time, the shielding sleeve 20 is made of aluminum material, which can also have a heat conductive effect, and can avoid the temperature of the power cord body 1 from being too high. The insulating sleeve 21 can increase the insulation capacity of the power cord body 1.

[0045] The use process of the utility model is as follows: when in use, one end of the power cord body 1 is connected to the circuit board in the power charger, and then the power cord can supply power to the power charger;

Then the pressing block 11 is pushed to move the moving rod 10, the connecting rod 8, the moving block 7 and other components to the middle of the shell 2. At the same time, the power cord body 1 can be pulled to make the power cord body 1 longer. When pulling, pull the end with the plug. When the length is not enough, the same principle is used to move other moving rods 10, connecting rods 8 and other components to the middle of the shell 2. In this way, the length of the power cord body 1 can be increased again. In this way, the length of the power cord can be adjusted according to the actual situation when the power cord is in use, thereby avoiding the phenomenon that the power cord is not long enough.

[0047] When the length is adjusted, the pressing block 11 is released, and then the moving block 7, the moving rod 10 and the fixed block 13 can be moved upward under the action of the spring 12 rebounding, so that the annular pad 14 contacts the housing 2 again, so that the moving rod 10 and other components can be prevented from moving at will;

[0048] When the power cord body 1 needs to be received into the housing 2, the pressing block 11 is pushed outward in sequence according to the same principle, so that the power cord body 1 can be pulled back into the housing 2, thereby preventing the power cord body 1 from being exposed to the air for a long time, thereby achieving a protective effect.

[0049] The above are only preferred embodiments of the present invention. Any person skilled in the art may modify the present invention or modify it into an equivalent technical solution by using the above technical solution.
