[0022] In the above structure, the base 1 plays a role of supporting the main body, the socket 2 is used to plug in a smart terminal or a wireless power bank, and the probe assembly 24 is used to realize power transmission. On this basis, the socket 2 is connected to the base 1 through the cooperation and rotation of the lower shaft 20 and the axial hole 10, so that the angular position of the socket 2 can be adjusted arbitrarily, which is convenient for users to adjust the orientation of the socket 2 for convenient plugging in a smart terminal or a wireless power bank. At the same time, based on the elastic abutment between the elastic arm top bead 23 on the elastic arm 22 and the multiple top bead limiting recesses 11 around the axial hole 10, the socket 2 can have a certain adjustment damping during the process of adjusting the angular position, and after adjustment, the socket 2 is limited to the specified angular position, thereby realizing non-azimuth fixation, which better meets the application requirements.

[0023] In order to balance the stress at both ends of the angle limiting piece 21 and improve the angular position limiting capability, in the present embodiment, the angle limiting piece 21 includes two elastic arms 22 symmetrically arranged on both sides of the angle limiting piece 21 .
