[0035] The angle switching connection component 3 includes a bottom buckle 3-1, which is fixedly connected to the back of the display screen body 1. The inner wall of the bottom buckle 3-1 is provided with a plurality of positioning grooves 3-2. The bottom buckle 3-1 is connected with a buckle cover 3-3. The buckle cover 3-3 is provided with a plurality of first positioning pieces 3-4 inside. A positioning pin 3-5 is movably inserted on the first positioning piece 3-4. A round head 3-6 is provided at the end of the positioning pin 3-5. The round head 3-6 is embedded in the positioning groove 3-2. A push spring 3-7 is provided on the first positioning piece 3-4. A top plate 3-8 is mounted on the positioning pin 3-5. The end of the push spring 3-7 is in contact with the top plate 3-8.

[0036] In this embodiment, the set track 2 can enable the display screen body 1 to be installed by horizontal sliding. After the bottom buckle 3-1 and the buckle cover 3-3 are buckled and connected, the push spring 3-7 can push the top plate 3-8 to embed the round head 3-6 on the positioning pin 3-5 into the positioning groove 3-2, so as to position the display screen body 1. When the display screen body 1 rotates, the round head 3-6 can be separated from the positioning groove 3-2. After the display screen body 1 rotates 90°, the round head 3-6 is again embedded in the positioning groove 3-2 for positioning.

[0037] Specifically, an embedding groove 3-9 is opened along the outer wall of the bottom buckle 3-1, and a positioning ring 3-10 is provided along the inner wall of the buckle cover 3-3. The positioning ring 3-10 is embedded in the embedding groove 3-9, and the structure of the embedding groove 3-9 matches that of the positioning ring 3-10.

[0038] In this embodiment, the positioning ring 3-10 is embedded in the embedding groove 3-9, which can make the buckle cover 3-3 slide smoothly on the bottom buckle 3-1 and ensure the rotation of the bottom buckle 3-1.
