This utility model relates to the field of auxiliary carrying devices, and discloses an auxiliary carrying device for backpacks, comprising a tennis bag, a bracket, a clip, a first elastic plate, a second elastic plate, and a pressing block. The bracket is mounted on the surface of the tennis bag, and the bracket has a clip. The first elastic plate is mounted on the inner wall of the clip via a rotating joint, and an arc-shaped second elastic plate is provided at its bottom. The surface of the second elastic plate has a pressing block. Both the first and second elastic plates penetrate the surface of the clip, and the inner wall of the clip has friction protrusions. This device achieves a stable connection between the bracket and the
tennis racket through a slotted joint, ensuring a secure installation of the
tennis racket. The U-shaped clip and the friction protrusions on the inner wall increase the friction with the side pocket of the backpack, allowing the bracket and tennis bag to be stably installed on the backpack surface, preventing the
tennis racket from easily falling off during vigorous movements. The elastic plate structure allows the clip to stably hold the side pocket of the backpack without affecting the use of the backpack, facilitating the taking and putting away of the tennis racket, and preventing the tennis racket from hitting the back during movement, thus improving user comfort.
