[0002] In order to kill time on the road and avoid boredom, passengers sitting in the back seat of a car will use tablets to watch videos, play games, read novels, etc. However, since there is generally no device to fix the tablet on the back of the front seat of the current car, the passengers have to hold the tablet by hand. Holding the tablet for a long time will easily cause arm soreness. In order to prevent arm soreness, passengers will use tools such as tape or clips to fix the tablet on the back of the front seat of the car. However, this method makes it difficult to stably fix the tablet on the back of the front seat, and it is easy to shake. It is also difficult to adjust the angle of the tablet according to the user's sitting position and angle, which makes it very inconvenient for the user to use the tablet and reduces the user's experience. In this regard, we propose a car front seat back placement rack. Utility Model Content
