(1) firstly, the operating element 34 is operated to drive the elastic element 35 to generate elastic deformation along the second direction under the limiting action of the first elastic limiting hole 212 and the second elastic limiting hole 342, so as to drive the limiting part 312 to leave from the limiting groove 132, the fixing state is released, and the sliding part 311 enters the sliding groove 131;

(2) applying an external force to the operating element 34 and driving the sliding portion 311 to slide on the guide element 10 along the first direction, at this time, the adjusting assembly 30 is switched to the adjusting state, so as to drive the corner protection assembly 20 to slide to a side close to the fixed element 200, the corner protection assembly 20 drives the positioning element 40 to leave from the second positioning groove 122 and slide along the positioning surface 11 until the positioning element 40 is positioned on the first positioning groove 121, and at this time, the sliding portion 311 enters the limiting groove 132 corresponding to the second positioning groove 122;

(3) the operating part 34 is loosened, under the action of the elastic force of the elastic part 35, the adjusting part 31 slides along the second direction, so that the limiting part 312 is slid into the limiting groove 132, the limiting part 312 is in limiting abutment with the inner wall of the limiting groove 132, the elastic part 35 restores to the original shape, at this time, the surrounding part of the corner protection component 20 extends out and is surrounded on the fixed part 200, the adjusting component 30 is switched to the fixed state, and the corner protection component 20 can protect the corner position of the fixed part 200.

Similarly, the corner fixing device 100 may be switched from the fixing state where the corner fixing device and the fixed object 200 are close to each other to the fixing state where the corner fixing device and the fixed object are far away from each other, and the sliding direction in the first direction in the above process may be reversed, which is not described herein again.

According to another aspect of the present application, there is provided a display screen unit, comprising a fixed member 200 and the corner fixing device 100 proposed in any of the above embodiments, wherein the corner protection assembly 20 can be fixed at the corner of the fixed member 200 and fixed, and 200 is a display screen.

Preferably, a corner fixing device 100 can be respectively arranged at four corners of the display screen, which are easy to collide, so that the effect of protecting four corners of the display screen at the same time can be realized, and the protection effect is further improved.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the utility model. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
