For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described below.

[0023] To address the problems existing in the background technology, this application proposes the following technical solution: a portable power bank with easily retractable plugs.

[0024] The specific technical solution includes a housing 1 and a rotatable power transmission component 3;

[0025] like Figure 1-4 As shown, the side wall of the outer casing 1 has a groove 2; the rotatable power transmission component 3 is installed in the groove 2 and is used to charge the power bank. The rotatable power transmission component 3 includes a plug body 301 located in the groove 2. The plug body 301 can easily support the pins 302. Two pins 302 located in the groove 2 are symmetrically installed on the plug body 301. The pins 302 can be connected to the socket. Two rotating shafts 303 passing through the side wall of the plug body 301 are symmetrically installed on the side wall of the plug body 301. The rotating shafts 303 can connect the plug body 301 and the groove 2. A limiting block 304 is fixedly installed at the center of the side wall of the plug body 301. The limiting block 304 can limit the plug body 301. An anti-slip groove 4 is provided on the side wall of the plug body 301 between the two pins 302. The anti-slip groove 4 can improve the friction between the finger and the plug body 301.

[0026] By pressing the anti-slip groove 4 with a finger, the anti-slip groove 4 is turned, causing the insert body 301 to rotate. The insert body 301 drives the rotating shaft 303 to rotate. The insert body 301 and the rotating shaft 303 rotate around the central axis of the rotating shaft 303. The rotation of the insert body 301 drives the insert pin 302 to rotate, which can rotate the insert pin 302 out of the groove 2, so that the insert pin 302 is perpendicular to the side wall of the outer shell 1 where the groove 2 is opened. When the insert body 301 rotates, it can drive the limiting block 304 to rotate. After the limiting block 304 rotates, it presses against the bottom surface of the groove 2. The limiting block 304 is limited, which drives the insert body 301 to be limited. The limiting of the insert body 301 limits the insert pin 302, so that the insert pin 302 can always remain perpendicular to the side wall of the outer shell 1 where the groove 2 is opened, which can prevent the angle of rotation of the insert pin 302 from being too large.

[0027] like Figure 3 As shown, a fixing plate 5 is fixedly installed inside the outer shell 1. The fixing plate 5 can fix and support the side plate 6. Two side plates 6 located in the groove 2 are symmetrically installed on the fixing plate 5. The side plates 6 can limit the rotation shaft 303. Each side plate 6 is respectively sleeved on each rotation shaft 303. Each side plate 6 is provided with a toothed groove 7. The toothed groove 7 can mesh with the tooth 8. Each rotation shaft 303 is fixedly installed with a tooth 8 that meshes with the toothed groove 7. The tooth 8 can mesh with the toothed groove 7.

[0028] The fixing plate 5 is fixed by the outer shell 1. After the fixing plate 5 is fixed, it can drive the side plate 6 to be fixed. The side plate 6 can drive the tooth groove 7 to be fixed. When the rotating shaft 303 rotates, it can drive the tooth 8 to rotate. The tooth 8 rotates in the tooth groove 7. The tooth 8 is made of silicone. The tooth 8 is deformed by the tooth groove 7. After the tooth 8 rotates, it can be stuck between the tooth grooves 7. The tooth 8 can drive the rotating shaft 303 to be limited.

[0029] like Figure 1 and Figure 4 As shown, a charging cable 9 is threaded through the side wall of the outer casing 1, and the charging cable 9 can supply power to the electrical device.

[0030] like Figure 3 As shown, a battery pack 10 is fixedly installed inside the outer casing 1, and the battery pack 10 can be used to store electrical energy.

[0031] like Figure 4 As shown, the side wall of the outer casing 1 is provided with a charging hole 11 and a charging hole 2 12 located on one side of the charging hole 11. The charging hole 11 and the charging hole 2 12 can be used to charge different devices.
