The pin mechanism 50 includes a pin assembly 51 slidably coupled within the housing 20 and an operating assembly 53 slidably coupled to the housing, preferably the operating assembly 53 is slidably inserted into the pin assembly 51. The pin assembly 51 includes at least one first magnetic member 510 and a pin sheet 511; the operation assembly 53 includes a second magnetic member 530 and a third magnetic member 531 at intervals, and the second magnetic member 530 and the third magnetic member 531 are arranged at intervals along the sliding direction of the operation assembly 53. Sliding the operating component 53 to drive the second magnetic member 530 to move closer to the first magnetic member 510, so that the pin assembly 51 slides in the first direction until the pin sheet 511 extends out of the housing 20 (as shown in fig. 12); the sliding of the operating component 53 drives the third magnetic member 531 to move closer to the first magnetic member 510, so that the pin assembly 51 slides along the second direction until the pin piece 511 is retracted into the housing 20 (as shown in fig. 1). The first direction is a direction in which the pin blade 511 slides toward the outside of the housing 20 to extend out of the housing 20, and the second direction is a direction in which the pin blade 511 slides toward the inner cavity of the housing 20 to retract into the inner cavity of the housing 20.

When the adapter 100 is needed to be used, the user manually operates the operating component 53 to slide along the first direction to drive the second magnetic member 530 to move toward the first magnetic member 510, and the magnetic force between the first magnetic member 510 and the second magnetic member 530 drives the pin component 51 to slide along the first direction until the pin piece 511 extends out of the housing 20. At this time, it is convenient for the user to plug the pin blade 511 of the adapter 100 into the socket, so that the circuit board 30 is electrically connected to an external power source. When the adapter 100 needs to be stored, the user manually operates the operation assembly 53 to slide along the second direction, so as to drive the third magnetic member 531 to move toward the first magnetic member 510, and the magnetic force between the first magnetic member 510 and the third magnetic member 530 drives the pin assembly 51 to slide along the second direction until the pin sheet 511 extends out of the housing 20. At this time, the accommodation of the pin sheet 511 is facilitated, and the pin sheet 511 is prevented from being damaged.

The adapter 100 in the present invention may be, but is not limited to, a power adapter, a portable charger, a router, a sound device, a router, a light bar, etc., and the power adapter is described in detail in this embodiment.

The pin assembly 51 of the adapter 100 of the present invention is slidably connected to the housing 20, the operation assembly 53 is slidably connected to the housing 20, and the pin assembly 51 is provided with a first magnetic member 510, and the operation assembly 53 includes a second magnetic member 530 and a third magnetic member 531 spaced from each other. When the operating member 53 is operated to slide in the first direction, the magnetic force between the first magnetic member 510 and the second magnetic member 530 drives the pin assembly 51 to slide in the first direction as well until the pin blade 511 protrudes out of the housing 20. At this time, the user can conveniently insert the pin blade 511 of the adapter 100 into the socket, and the operation is simple and the use is convenient. When the operating member 53 is operated to slide in the second direction, the magnetic force between the first magnetic member 510 and the third magnetic member 530 drives the pin assembly 51 to slide in the second direction as well until the pin blade 511 protrudes out of the housing 20. At this time, the accommodation of the pin blade 511 is facilitated, and the pin blade 511 is prevented from being damaged or contaminated.

The circuit board 30 is electrically connected with the pin sheet 511 through a wire 31, and the wire 31 between the pin sheet 511 and the circuit board 30 is provided with a reserved section 312. The reserved section 312 refers to the curved conductor 31 between the pin sheet 511 and the circuit board 30 when the pin sheet 511 is retracted into the inner cavity of the housing 20. The reserved section 312 prevents the pin blade 511 from being broken by the wire 31 during the process of extending out of the housing 20; i.e. the wire 31 has a length sufficient to facilitate sliding movement of the pin assembly 51.

In this embodiment, the first magnetic member 510, the second magnetic member 530, and the third magnetic member 531 are all magnets. The first magnetic member 510 and the second magnetic member 530 have a magnetic force therebetween that drives the pin assembly 51 to slide along a first direction, and the first magnetic member 510 and the third magnetic member 531 have a magnetic force therebetween that drives the pin assembly 51 to slide along a second direction, the first direction being opposite to the second direction. Specifically, the polar directions between the first magnetic element 510 and the second magnetic element 530 are the same, i.e., if the side of the first magnetic element 510 facing the second magnetic element 530 is the N-pole, the side of the second magnetic element 530 facing the first magnetic element 510 is also the N-pole; if the side of the first magnetic element 510 facing the second magnetic element 530 is the S-pole, the side of the second magnetic element 530 facing the first magnetic element 510 is also the S-pole. The polar directions between the first magnetic member 510 and the third magnetic member 531 are the same, i.e., if the side of the first magnetic member 510 facing the third magnetic member 531 is the N-pole, the side of the third magnetic member 531 facing the first magnetic member 510 is also the N-pole; if the side of the first magnetic member 510 facing the third magnetic member 531 is the S-pole, the side of the third magnetic member 531 facing the first magnetic member 510 is also the S-pole.

The closer the distance between the first magnetic member 510 and the second magnetic member 530, the stronger the magnetic force driving the pin assembly 51 to slide in the first direction; the closer the distance between the first magnetic member 510 and the third magnetic member 531 is, the stronger the magnetic force driving the pin assembly 51 to slide along the second direction is. Specifically, since the polar directions between the first magnetic member 510 and the second magnetic member 530 are the same, when the operating member 53 slides with respect to the pin member 51 such that the distance between the second magnetic member 530 and the first magnetic member 510 becomes gradually smaller, the magnetic force between the second magnetic member 530 and the first magnetic member 510 becomes gradually larger. Similarly, since the polar directions of the first magnetic member 510 and the third magnetic member 531 are the same, when the operating unit 53 slides relative to the pin unit 51 to gradually decrease the distance between the third magnetic member 531 and the first magnetic member 510, the magnetic force between the third magnetic member 531 and the first magnetic member 510 gradually increases.

The pin piece 511 has the same sliding direction as the operation assembly 53 in the process of extending out of the housing 20 or retracting into the housing 20. Specifically, the operating component 53 moves along the first direction to move along the first direction with the second magnetic member 530, and the magnetic force between the second magnetic member 530 and the first magnetic member 510 causes the pin component 51 to slide along the first direction; the operation component 53 moves along the second direction to drive the third magnetic member 531 to move along the second direction, and the magnetic force between the third magnetic member 531 and the first magnetic member 510 causes the pin component 51 to slide along the second direction.
