Track, adapter and track light

An adapter, used for electrically connecting with a power supply device or a power consumption device and coupled in a track, wherein the track comprises,

• in a height direction, a side with an installation portion, and another side with a frame, and wherein the frame encloses to form an accommodating space with an opening direction that is away from the installation portion, the installation portion is used to connect with an installation foundation, and the accommodating space is used for accommodating the adapter;
• a first magnetic attraction piece, wherein the first magnetic attraction piece is used for magnetically connecting with the adapter;
• and
• a fastener holder, wherein the fastener holder is used for engaging with the adapter, and
• wherein the adapter realizes that the power supply device or the power consumption device obtains electricity from the track, and the adapter further comprises a housing, and first fasteners and an operating part arranged on the housing, wherein the first fasteners are configured to engage with the fastener holder, and the operating part is configured to be cooperated with the first fasteners, wherein the first fasteners are connected with a top plate of the housing through a first spring piece, the operating part is connected with a side plate of the housing through a second spring piece, a surface of the first fasteners that engaged with the operating part is an inclined surface, and a surface of the first fasteners opposite to the side plate is an inclined surface.
