A plurality of annular sleeves are installed on the left inner end face of the side plate from top to bottom, and the upper and lower end faces of the right vertical cavity are installed with shell plates through a sliding fit.

[0006] Preferably: The right end face of the cavity is rotatably installed with a main shaft through a pin shaft, and baffles are symmetrically installed on the upper and lower outer side walls of the main shaft.

[0007] Preferably: A circular groove is opened on the left end face of the baffle, and a first spring rod is installed on the left end face inside the circular groove.

[0009] Preferably: A T-shaped frame is installed on the upper end face of the fixing frame, bottom grooves are symmetrically opened on the front and back of the inner bottom of the T-shaped frame, a limiting spring is arranged in the bottom groove, the other end of the limiting spring is installed with a first slider, and a lower plate is installed at the bottom of the first slider.

[0010] Preferably: Fixing holes are symmetrically opened on the front and back end faces of the cavity, and the fixing holes are arranged at the outer end of the left vertical cavity.

[0011] Technical effects and advantages of the present utility model:

[0012] 1. In the present utility model, a sponge pad structure is adopted to shock-absorb and protect the charger head, avoiding damage to the bottom plug when the charger head 2 falls to the ground.

[0013] 2. In the present utility model, a plurality of fixing frames are adopted to be able to carry multiple data cables, avoiding entanglement and knotting. Also, an annular sleeve structure is adopted to clamp and fix one end of the wound data cable, preventing it from loosening and spreading. Description of the drawings

Detailed implementation manners

[0020] The present utility model will be further described in detail below in conjunction with the drawings and specific implementation manners. The invention of the present utility model is given for purposes of illustration and description, and is not intended to be exhaustive or to limit the present utility model to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The invention is selected and described to better illustrate the principles and practical applications of the present utility model, and to enable those of ordinary skill in the art to understand the present utility model and thus design various inventions suitable for specific purposes with various modifications.

[0021] Please refer to Figures 1 to 5, in this embodiment, a portable charger is provided, which includes a cavity 1 and a charging head 2. An upper end face of the cavity 1 is provided with a left vertical cavity 11, a right vertical cavity 12 is arranged to the right of the left vertical cavity 11. A sponge pad 13 is installed at the inner bottom of the left vertical cavity 11. The charging head 2 is installed on the upper end face of the sponge pad 13 in a plug-in manner. A cover plate 14 is rotatably installed on the upper end face of the left vertical cavity 11 through a pin shaft. Side plates 15 are installed on the left and right side walls in the right vertical cavity 12 in a sliding fit manner. The inner side ends of the side plates 15 are connected by a plurality of fixing frames 16. A plurality of annular sleeves 17 are installed on the inner left end face of the side plates 15 from top to bottom. Shell plates are installed on the upper and lower end faces of the right vertical cavity 12 in a sliding fit manner. During operation, the charging head 2 is shock-absorbed and protected by the sponge pad 13 to prevent damage to the bottom plug when the charging head 2 falls to the ground. One end of the data cable is wound around the fixing frame 16, and the other end of the data cable is inserted into the annular sleeve 17 for fixation to ensure the winding effect of the data cable and prevent it from loosening and spreading. By adopting the structure of a plurality of fixing frames 16, multiple data cables can be carried to avoid winding and knotting.

[0022] A main shaft 18 is rotatably installed on the right side end face of the cavity 1 through a pin shaft. Baffles 19 are symmetrically installed on the outer side wall of the main shaft 18 up and down. During operation, the baffles 19 limit the shell plates to prevent relative sliding of the shell plates. When in use, the main shaft 18 is rotated by 90 degrees to drive the shell plates to move to the right, facilitating the extraction of the data cable for use.

[0023] A circular groove is provided on the left side end face of the baffle 19. A first spring rod 21 is installed on the left side end face in the circular groove. During operation, the first spring rod 21 presses to the left, improving the connection stability between the baffle 19 and the shell plate.

[0024] A U-shaped frame is installed on the upper end face of the annular sleeve 17. An adjusting spring 22 is installed on the inner top of the U-shaped frame. The other end of the adjusting spring 22 is installed with a pressing plate 23, and the pressing plate 23 is arranged inside the annular sleeve 17. During operation, the adjusting spring 22 drives the pressing plate 23 to move downward to press the other end of the data cable, improving the pressing effect on the data cable.

[0025] A T-shaped frame is installed on the upper end face of the fixing frame 16. Bottom grooves are symmetrically provided on the front and rear of the inner bottom of the T-shaped frame. Limiting springs 24 are arranged in the bottom grooves. The other ends of the limiting springs 24 are installed with first sliders, and a lower plate 25 is installed at the bottom of the first sliders. During operation, the limiting springs 24 drive the lower plate 25 to move inwards to press and fix the front and rear end faces of the data cable, further improving the winding stability and preventing the data cable from loosening and spreading.

[0026] Fixing holes 26 are symmetrically provided on the front and rear end faces of the cavity 1, and the fixing holes 26 are arranged at the outer side end of the left vertical cavity 11. During operation, through the fixing holes 26, the user can directly touch the charging head 2 to take it out, preventing the charging head 2 from being stuck in the left vertical cavity 11 and being difficult to take out.

[0027] During specific operation, the charging head 2 is shock-absorbed and protected by the sponge pad 13 to prevent damage to the bottom plug of the charging head 2 when it falls to the ground. One end of the data cable is wound around the fixing frame 16, and the other end of the data cable is inserted into the annular sleeve 17 for fixation to ensure the winding effect of the data cable and prevent it from loosening and spreading. By adopting a plurality of fixing frame 16 structures, multiple data cables can be carried to avoid entanglement and knotting.

[0028] Obviously, the described invention is only a part of the invention of the present utility model, rather than all of the inventions. All other inventions obtained by those of ordinary skill in the art and related fields based on the inventions in the present utility model without creative efforts shall fall within the protection scope of the present utility model. Structures, devices, and operation methods not specifically described and explained in the present utility model shall be implemented by conventional means in the art without special instructions and limitations.
