[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] like Figures 1 to 7As shown, the expandable metal adapter of the utility model includes an adapter 1, which is connected to a charging head 2, and then the other end can be connected to an external power source. A docking groove 3 is provided on the charging head 2, and a limiting arc groove 4 is provided on the inner wall of the docking groove 3. A positioning block 5 is placed in the limiting arc groove 4. The limiting arc groove 4 has a certain depth, so that when the positioning block 5 is located therein, the charging head 2 and the adapter 1 are kept connected. When the line body of the adapter 1 is affected by external forces, the adapter 1 can be kept from being separated from the charging head 2.

[0024] The adapter 1 is provided with a mounting groove 6 and movable grooves 7 arranged at both ends of the mounting groove 6. The mounting groove 6 is used for installing the pressure block 8 and the elastic member 9, and the movable groove 7 is used to keep the positioning block 5 from being pushed downward by the pressure block 8, so that the positioning block 5 rotates around the lower end at a certain angle, so that the upper end of the positioning block 5 enters the movable groove 7, so that the upper end of the positioning block 5 is lower than the outer wall of the adapter 1. After the adapter 1 is docked with the charging head 2, the pressure block 8 no longer applies pressure to the positioning block 5, and the positioning block 5 can be kept pushed back under the action of the spring 10, so that the upper end of the positioning block 5 is higher than the outer wall of the adapter 1, thereby keeping the upper end of the positioning block 5 in the limiting arc groove 4.

[0025] A pressure block 8 is provided in the installation groove 6, a connecting column 11 is provided on the pressure block 8, and a connecting hole 12 is provided on the adapter 1 for the connecting column 11 to move, and the connecting hole 12 is communicated with the installation groove 6. A pressing block 13 is provided on the connecting column 11, and an elastic member 9 is provided in the installation groove 6, and the elastic member 9 is located at the lower end of the pressure block 8. When the pressing block 13 is pressed, the pressure block 8 is kept moving downward, pressing the elastic member 9, so that the elastic member 9 is deformed, thereby maintaining the elastic member 9 to generate a reverse elastic force.

[0026] The elastic member 9 is composed of an arc segment 14 and horizontal segments 15 arranged at both ends of the arc segment 14. The horizontal segment 15 is located at the lower end of the pressure block 8. A limiting arc opening 16 cooperating with the arc segment 14 is arranged in the mounting groove 6.

[0027] The cross section of the pressure block 8 is trapezoidal, with a wider upper end surface and a narrower lower end surface. The positioning block 5 can be pushed by the inclined surfaces on both sides of the pressure block 8 to rotate.

[0028] A positioning block 5 is provided in the movable groove 7, and the positioning block 5 is hinged in the movable groove 7. The positioning block 5 is arranged on both sides of the pressure block 8. A positioning column 17 is provided at one end of the positioning block 5 away from the pressure block 8. A spring 10 is provided on the positioning column 17. A positioning hole 18 is provided in the movable groove 7. One end of the spring 10 is in contact with the positioning block 5, and the other end is placed in the positioning hole 18.

[0029] The lower end of the positioning block 5 is provided with a circular end 19, and the movable groove 7 is provided with an arc groove 20 that matches the circular end 19. The angle of the arc groove 20 is a major arc, that is, the arc angle of the arc groove 20 is greater than 180 degrees. In addition, a notch 21 is provided on one side of the positioning block 5, and the notch 21 is used to keep the positioning block 5 from rotating smoothly.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
