a first protrusion 21 is formed on the peripheral wall of the rotating shaft 20 in an outward extending manner, the keys 40 are distributed on the peripheral side of the rotating shaft 20, and a top column 41 for aligning and clamping with the first protrusion 21 is arranged on the lower end of the key 40 in an extending manner towards the rotating shaft 20; when the key 40 is in the initial limit state, the top pillar 41 is in counterpoint engagement with the first protrusion 21 and the pin 30 is completely accommodated in the accommodating groove a; when the key 40 is pressed, the top pillar 41 is separated from the first protrusion 21 and the outer ends of the pins 30 are exposed to the receiving groove a under the driving of the rotating shaft 20.
Therefore, the foldable plug of the embodiment is matched with the elastic component through the key 40, the elastic component drives the rotating shaft 20 to automatically rotate, so that the outer ends of the pins 30 are exposed out of the accommodating grooves a and distributed, and meanwhile, the top pillar 41 on the key 40 is matched with the first protrusion 21 to prevent the rotating shaft 20 from rotating, so that when the plug is not used, the plug can be completely retracted and distributed in the accommodating grooves a to solve the problem that the pins 30 of the pull-out or pull-out type foldable plug need to be exposed; when the plug is required to be charged or power is supplied, the push button 40 is only required to be pressed to trigger the top column 41 to be separated from the first bulge 21, namely the top column 41 is contacted to limit the rotation, so that the plug pin 30 can automatically rotate and pop up, and a user can use the plug pin conveniently; after the use, the pin 30 can be manually rotated reversely, so that the pin 30 is accommodated in the accommodating groove a again, and the top column 41 on the key 40 can be aligned and clamped with the first protrusion 21 again to limit the rotating shaft 20.

In order to optimize the structure of the key 40, a return spring 42 is disposed in the housing 10 of the present embodiment and at the lower end of the key 40; when the key 40 is in an initial limiting state, the return spring 42 drives the top column 41 to move upwards so as to be aligned and clamped with the first protrusion 21; in the pressed state of the push button 40, the return spring 42 is compressed and the top post 41 is separated from the first projection 21. Therefore, the elastic force provided by the return spring 42 at the lower end of the key 40 can be used for keeping the top column 41 on the key 40 in a clamping state with the first bulge 21; meanwhile, by means of the arrangement of the return spring 42, a certain movement space is formed between the key 40 and the inner bottom surface of the shell 10, so that when the key 40 is pressed, the key 40 and the top column 41 on the key 40 can move downwards, and the top column 41 is separated from the first protrusion 21; after the use, when the pin 30 is manually retracted, the top pillar 41 can be pushed by the first protrusion 21 to move downward, and when the pin 30 is completely accommodated in the accommodating groove a, the top pillar 41 can be automatically pushed downward by the action of the return spring 42 to be aligned and clamped with the first protrusion 21, so that the rotation of the rotating shaft 20 is limited, and the use is convenient.
In order to optimize the structure of the elastic assembly, as one preferred scheme, the elastic assembly of the present embodiment includes a first elastic sheet 51 disposed in the housing 10 and distributed below the contour of the rotating shaft 20, a second protrusion 22 extending outward from the peripheral wall of the rotating shaft 20 and distributed in alignment with the first elastic sheet 51, and when the pin 30 is completely received in the receiving groove a, the second protrusion 22 abuts against the first elastic sheet 51 to press the first elastic sheet 51; in the initial position-limiting state of the push button 40, the first resilient tab 51 presses the second protrusion 22 in the opposite direction to drive the rotating shaft 20 to rotate and expose the outer ends of the pins 30 in the receiving grooves a. Therefore, the second protrusion 22 can be used to be matched with the first elastic sheet 51, and the second protrusion 22 rotates along with the rotating shaft 20 when the pin 30 is retracted, so as to press the first elastic sheet 51, so that the first elastic sheet 51 is deformed; when the top pillar 41 of the key 40 is separated from the first protrusion 21, the first resilient sheet 51 is automatically reset, so as to provide power for the rotating shaft 20 and drive the rotating shaft 20 to automatically rotate.
In order to simplify the structure of the rotating shaft 20, the first projection 21 and the second projection 22 of the present embodiment are combined into a connected body. That is, the first protrusion 21 and the second protrusion 22 may be located on the peripheral wall of the rotating shaft 20 and on the same line, so that the first protrusion 21 and the second protrusion 22 may be combined into a connected body, thereby simplifying the structure of the rotating shaft 20 and facilitating the processing of the rotating shaft 20.
Further, the first elastic piece 51 of the present embodiment may be made of a metal material or a plastic material.

Preferably, two torsion springs 52 are provided and are respectively provided at both ends of the rotating shaft 20. Therefore, when the pin 30 is retracted, the torsion spring 52 can rotate along with the rotating shaft 20 to generate a certain deformation and torsion force, and when the top pillar 41 on the key 40 is separated from the first protrusion 21, the torsion force of the torsion spring 52 can be automatically released, i.e. the torsion spring provides power for the rotating shaft 20 to drive the rotating shaft 20 to rotate automatically. It should be noted that, the torsion spring 52 and the first elastic sheet 51 can be used independently or simultaneously to enhance the automatic rotation effect of the rotating shaft 20.
In order to ensure that the pins 30 can be completely accommodated in the accommodating grooves a, pressing grooves b formed by being recessed inward are formed on the top surface of the housing 10 and located on both sides of one of the accommodating grooves a. When the plug is used and the pin 30 is manually accommodated, the pin 30 can be completely accommodated in the accommodating groove a by pressing the pin 30 at the position of the pressing groove b, the pin 30 can be prevented from being exposed, and the top column 41 and the first protrusion 21 can be in the alignment and engagement state.

Under the action of the elastic element (i.e. under the action of the torsion spring 52 and/or the first elastic sheet 51), the pin 30 will automatically bounce and rotate along with the rotating shaft 20 and be exposed out of the folding groove a, but the elastic element does not need to have too strong elastic force, and the elastic element is not convenient to fold reversely because of too strong elastic force, and the elastic element only needs to provide certain elastic force to enable the pin 30 to automatically rotate and be exposed out of the folding groove a (as shown in fig. 6 and 7); meanwhile, in order to facilitate the user to use the plug by plugging, the pin 30 can be further rotated manually to make the pin 30 perpendicular to the top surface of the housing 10 (as shown in fig. 8-11), and at this time, the arc-shaped groove 31 is engaged with the arc-shaped protrusion 61, and the second elastic sheet 60 abuts against the bottom end of the pin 30, so that the pin 30 can be kept perpendicular to the top surface of the housing 10 for the user to use.
Preferably, the second elastic sheet 60 of the present embodiment further extends to form a V-shaped or U-shaped abutting portion 62, a plugging hole c aligned with the abutting portion 62 is formed on the bottom surface of the housing 10, and the abutting portion 62 is exposed out of the housing 10 through the plugging hole c and is used for aligning and plugging the circuit board 71 so as to electrically connect the circuit board 71 and the abutting portion 62.
