[0031] Among them, the supporting mechanism 5 also includes a cylindrical movable cavity 58 opened in the movable base rod 52, a cylindrical movable seat 510 and a spring A59 installed in the cylindrical movable cavity 58, and a cylindrical connecting rod 57 fixed on the front surface of the cylindrical movable seat 510. The front end of the cylindrical connecting rod 57 passes through the front end of the movable base rod 52 and is fixed to the support block 53, so that the subsequent support block 53 can be pulled forward and rotated.

[0032] Among them, the front end of the spring A59 abuts against the front end inner wall of the cylindrical movable cavity 58, and the rear end of the spring A59 abuts against the front surface of the cylindrical movable seat 510.

[0033] A circular rod hole communicating with the cylindrical movable cavity 58 is formed through the front end surface of the movable base rod 52 , and the circular rod hole corresponds to the cylindrical connecting rod 57 , so that the cylindrical connecting rod 57 can pass through and move smoothly.

[0034] The cylindrical connecting rod 57 passes through the inner center of the spring A59, so that the cylindrical connecting rod 57 will not affect the normal telescopic deformation of the spring A59.

[0035] Among them, the supporting mechanism 5 also includes side grooves 511 opened inside the two sides of the inner sliding seat 56, springs B512 and semicircular side clamps 513 installed inside the side grooves 511, and the inner walls on both sides of the inner sliding groove 55 are provided with two rectangular clamping grooves 514 corresponding to the semicircular side clamping blocks 513. The semicircular side clamping blocks 513 are movably installed in the side grooves 511 through springs B512, and the ends of the semicircular side clamping blocks 513 pop out into one of the rectangular clamping grooves 514 to realize the locking and limiting of the inner sliding seat 56 after sliding.

[0036] One end of the spring B512 is fixed to the inner wall of the side groove 511 , and the other end of the spring B512 is fixedly connected to the semicircular side clamping block 513 .

The inner wall surface of the cover 4 is provided with multiple integrated L-shaped elastic clips 43.

[0039] In summary, when the charger needs to be used for plug-in charging, the support block 53 can be pulled forward with force first, so that the cylindrical connecting rod 57 pulls the cylindrical movable seat 510, causing the cylindrical movable seat 510 to slide forward and gradually compress the spring A59, so that the support block 53 and the support sleeve 54 can move forward smoothly until the support sleeve 54 slides away from the front end of the conductive pin 13, and then the support block 53 is rotated ninety degrees, so that the support sleeve 54 is no longer aligned with the conductive pin 13, and the cylindrical connecting rod 57 and the cylindrical movable seat 510 will also rotate in the cylindrical movable cavity 58 during the rotation. After the rotation of the support block 53 is completed, the support block 53 is released, and the spring A59 pushes the cylindrical movable seat 510 back to reset, and the cylindrical connecting rod 57 rebounds with the support block 53, and then the support block 53 and the movable base rod 52 are pushed toward the end seat 12, so that the inner slide seat 56 is pushed, and the end of the semicircular side block 513 is gradually squeezed into the side groove 511, so that the inner slide seat 56 slides smoothly, until the support block 53 is pushed into the strip notch 51, and the inner slide seat 56 is pushed to the rear end of the inner slide groove 55, at this time, the semicircular side block 513 is pushed into the side groove 511, and the inner slide seat 56 is pushed into the side groove 55. The end portion will be pushed by the spring B512 to pop out into the rectangular slot 514 on the inner wall at the rear end of the inner slide 55, realizing the limit of the inner slide seat 56 and the movable base rod 52. At this time, the support block 53 is in the strip notch 51, and the two support sleeves 54 are respectively in front of and behind the end seat 12, so that the conductive pin 13 can be smoothly inserted into the wall socket for power connection without affecting the smooth insertion of the conductive pin 13. Then, the connecting line of the device to be charged can be inserted into the charging socket 41 or the USB socket 42 on the cover plate 4 for charging. When the charger needs to be put into the bag for carrying and transportation later, During transportation, the support block 53 can be first pulled out of the strip notch 51 with force, so that the inner slide seat 56 slides to the front end of the inner slide groove 55, and then the support block 53 is pulled forward with force until the support block 53 rotates to align the support sleeve 54 with the front end of the conductive pin 13, and then the support block 53 is released, so that the spring A59 pushes back the cylindrical movable seat 510 and the support block 53 is pulled back to reset, and finally the support sleeve 54 is sleeved on the front end of the conductive pin 13, so that the conductive pin 13 can be effectively supported and prevented from being bent and damaged by external force.
