[0033] The specific working principle and usage method of the utility model are as follows:

[0034] The utility model provides an adjustable rear flat fork for an electric vehicle. When in use, a staff member can rotate the positioning bolt 15 according to demand to separate the positioning bolt 15 from the threaded hole 2 12, thereby releasing the limiting relationship between the extension plate 14 and the extension slide cavity 11. Then, the extension plate 14 can drive the limiting slide plate 13 to slide inside the extension slide cavity 11, thereby adjusting the use spacing between the cross plate 13 and the cross plate 2 4, thereby adjusting the overall use width of the entire rear flat fork. After adjusting to a suitable width, the positioning bolt 15 can be screwed into the threaded hole 2 12 by rotating the positioning bolt 15 in the reverse direction, thereby limiting the extension plate 14, thereby completing the adjustment of the overall use width of the entire rear flat fork. By rotating the positioning bolt 27 to separate the positioning bolt from the threaded hole 10, the limiting relationship between the extension arm 8 and the extension slide 9 is released. Then, the extension arm 8 can slide on the inner wall of the extension slide 9 under the action of the limiting slide 17 and the limiting slider 16, so that the overall use length of the flat fork arm 6 can be adjusted. After adjusting to a suitable length, the positioning bolt 27 can be screwed into the threaded cap hole 1 by rotating the positioning bolt 27 in the opposite direction, so that the extension arm 8 can be limited, thereby completing the adjustment of the overall use length of the flat fork arm 6. In this way, the entire rear flat fork can be adjusted to different sizes to be suitable for installation and use of wheels of different models, thereby improving practicality.
