[0046] Specifically, by setting the third motor 32 to drive the driving wheel 33 and the driven wheel 34 to transmit on the transmission belt, driving the rotating piece 38, the rotating rod 39 and the cam follower 40 to slide inside the inner groove 43, thereby converting the rotational motion into a vertical motion. The two third motors 32 can separately drive four different types of groove bodies one 45, groove body two 46, groove body three 47, and groove body four 48 to be adapted to four different types of adaptation devices, facilitating the user to control the charging of one group of types of devices according to needs, expanding the usage range and convenience of the device main body 1.

[0050] Working principle:

[0051] First, when the device main body 1 needs to be moved, the device main body 1 is moved to the required position through the portable ring and placed on the ground for support through the outer housing 9. At this time, when charging a general mobile phone universal device, two pull rings on the cover plate 13 are opened, and the first motor 62 is started to drive the adjusting plate 64 on the screw rod 63 to move. While the adjusting plate 64 slides, it drives the adjusting rods one 67 at different levels connected to the adjusting plate 64 to slide on the slide rod one 66, thereby adjusting to the position of the interface 65 required by the user for use. While the adjusting plate 64 slides downward, the arc-shaped pieces 84 at different heights in the pressing assembly 8 are driven by the second motor 81, and the sleeve 83 drives the arc-shaped pieces 84 at different heights to rotate from the inside of the engaging groove 11 to the positions of the interfaces 65 of the adjusting structure 6, adjusting the charging interface 65 in real time to improve the safety performance of the device main body 1. And when the first motor 62 drives the adjusting plate 64 to move, the inner housing 2 connected thereto descends and rises accordingly, facilitating the support and movement of the device main body 1 by the four brake wheels at the bottom. When charging four other different types of devices, the third motor 32 is started to drive the driving wheel 33 and the driven wheel 34 to transmit on the transmission belt. At this time, the rotating piece 38, the rotating rod 39, and the cam follower 40 slide inside the inner groove 43. When the slot two 46 needs to be used, the electromagnetic clutch 341 on one of the driven shafts 37 is opened, and then one of the driven shafts 37 stops moving, and the driven shaft 37 on the driving wheel 33 rotates to drive the slot two 46 to rise. If the slot three 47 needs to be used, the other electromagnetic clutch 341 is closed. After use, the box door is closed, and the provided top plate 12 and cover plate 13 facilitate the protection of the internal components. When heat dissipation is required, the heat dissipation fan inside the inner housing 2 is started, and the heat dissipation fan dissipates heat through the slot one 45, the slot two 46, the slot three 47, the slot four 48, and the multiple engaging grooves 11, facilitating the extension of the service life of the device main body 1. Thus, the entire working process ends.
