The sound-absorbing cotton and the car hub cover can be fixed by gluing and staples; among them, gluing is not as firm as staples. The plastic fender and the car hub cover can be fixed by snaps and rivets; among them, snaps are not as reliable as rivets. Due to the large size and soft material of the wheel hub cover, the car hub cover is not stable when the sound-absorbing cotton is nailed and installed and the plastic fender is riveted, which makes the installation of the sound-absorbing cotton nailed and the installation of the plastic fender riveted inconvenient.

In order to meet the multi-point nailing operation, the position of the rear wheel cover inside the arc cover 6 can be manually adjusted, and the vacuum suction cup 13 is used for adsorption and fixing, which is easy to nail at different positions of the rear wheel cover. The control mode of the reduction motor 3 and the vacuum suction cup 13 of the utility model is controlled by manually starting and closing the switch. The wiring diagram of the power element and the provision of power supply belong to the common knowledge in the field, and the utility model is mainly used to protect the mechanical device, so the utility model will not explain the control mode and wiring arrangement in detail;

[0023] In one embodiment, two negative pressure shells 12 are provided on the outer side of the arc-shaped cover 6, and each negative pressure shell 12 is provided with a vacuum suction cup 13, and the vacuum suction cup 13 of the negative pressure shell 12 is connected to the external vacuum equipment through a vacuum pipe. Through the setting of two negative pressure shells 12, the rear wheel cover can be double-adsorbed, thereby increasing the stability of the rear wheel cover during the nailing stage.
