The invention discloses a charging needle and a charging device thereof, and relates to the technical field of charging equipment, the charging needle comprises a device main body, the device main body comprises an adaptive
assembly, an inner shell connected with the adaptive
assembly, an adjusting structure connected with the inner shell, and a pressing
assembly connected with the adjusting structure, the device has the advantages that the third motor is arranged to drive the driving wheel and the driven wheel to conduct transmission on the
transmission belt, the rotating piece, the rotating rod and the
cam follower are driven to slide in the inner groove, and therefore rotating motion is converted into
vertical motion; two third motors can independently drive a first groove body, a second groove body, a third groove body and a fourth groove body of different types to adapt to four different types of
adaptive equipment, so that a user can accurately match the type of the required charging equipment; therefore, the
wireless charging device can be widely applied to diversified scenes such as smart home, mobile office and public charging, and the requirement of a user for flexibly switching charging among different devices can be met.
