[0050] Furthermore, the portable component 300 includes a card block 300a disposed on the second screen panel 101c, a grip portion 301 rotatably connected to the card block 300a, a first connecting ring 302 connected to the grip portion 301, a second connecting ring 303 connected to the display screen body 102, and a rotating shaft 401 disposed between the first connecting ring 302 and the second connecting ring 303. A rotating groove 400 is provided on the card block 300a, and the first connecting ring 302 and the second connecting ring 303 are disposed in the rotating groove 400. A plurality of operation buttons 402 are provided on the grip portion 301.

[0051] Preferably, there are two grips 301. The grips 301 are bent toward the main frame 101b near the main frame 101b and are hinged to the main frame 101b after bending. Each grip 301 is provided with a card strap and a Velcro is provided at the end of the card strap. The two card straps can be glued together using the Velcro.

[0052] Preferably, a first mobile terminal 501 and a second mobile terminal 502 are respectively provided in the two grip portions 301. When the two grip portions 301 are rotated out by the user, the first mobile terminal 501 and the second mobile terminal 502 are simultaneously activated by the internal power supply and immediately send a signal transmission request to the control module 103, so that a signal transmission channel is established between the control module 103 and the first mobile terminal 501 and the second mobile terminal 502, thereby synchronizing the information received on the control module 103 to the first mobile terminal 501 and the second mobile terminal 502.

[0053] Preferably, an infrared sensor 407 is also provided on the grip portion 301.

[0054] Furthermore, a storage groove 503 is provided on the second connecting ring 303, and a first arc groove 504 is provided on the storage groove 503. The arc of the first arc groove 504 is consistent with the arc of the second connecting ring 303 and is connected to one side of the storage groove 503. An inward concave corner groove 505 is also provided on the storage groove 503, and a first top groove 506 is provided between the inward concave corner groove 505 and the first arc groove 504.

[0055] Furthermore, a first displacement groove 507 is provided at the end of the storage groove 503 away from the first arc groove 504. A first protrusion 508 is formed between the first displacement groove 507 and the concave corner groove 505. The first displacement groove 507 includes a displacement angle α and a displacement angle β. A second protrusion 509 is formed between the first displacement groove 507 and the side of the second connecting ring 303.

[0056] Furthermore, a locking block 600 is rotatably connected to the first connecting ring 302, and convex protrusions are formed at both ends of the locking block 600, namely convex protrusion a and convex protrusion b.

[0057] Preferably, a first contact electrode is provided in the first top groove 506, a second contact electrode corresponding to the first contact electrode is provided on the convex corner protrusion a, and a fourth contact electrode is provided on the convex corner protrusion b. When the first contact electrode and the second contact electrode are in contact, they will be energized to each other. When the convex corner protrusion a is engaged in the first top groove 506, the display screen body 102 and the grip part 301 are at a 90° angle. At this time, the grip part 301 will enter state 1. At this time, the operator can use the operation button 402 on the grip part 301 to assist in the control.

[0058] Preferably, a third contact electrode is also provided in the first arc groove 504. When the locking block 600 moves into the first arc groove 504 and the convex corner protrusion a connects with the end of the first arc groove 504, the first contact electrode and the third contact electrode are connected. At this time, the display screen body 102 is retracted to one side of the grip part 301. At this time, the auxiliary signal transmission function of the grip part 301 is unlocked, and then the auxiliary antenna on the grip part 301 enters the working mode, thereby further enhancing the signal transmission and reception performance.

[0059] Operation process: When the operator controls the grip 301 to rotate, the grip 301 drives the second connecting ring 303 to rotate, which in turn drives the locking block 600 to rotate. The movement path of the locking block 600 is as follows: In the initial state, the locking block 600 is in the storage groove 503, and the first contact electrode is in contact with the third contact electrode. As the display screen body 102 rotates, the first arc groove 504 gradually moves away from the locking block 600, thereby allowing the locking block 600 to move out of the first arc groove 504. Because the first displacement groove 507 changes to an angle α and the first arc groove 504... 04 is facing directly, and at this time the locking block 600 will directly abut against the changing angle α of the first displacement groove 507. Since one side of the changing angle α of the first displacement groove 507 is one side of the first protrusion 508, and this side has a certain inclination angle with the length direction of the locking block 600, when the second connecting ring 303 continues to rotate, the locking block 600 will be deflected towards the changing angle β of the first displacement groove 507 under the obstruction of the first protrusion 508, and will continue to be deflected under the obstruction of the changing angle β of the first displacement groove 507, so that the locking block 600 faces the first top groove 506.

[0060] At this point, the rotation angle of the gripping part 301 has exceeded 90°. Then, the operator rotates the gripping part 301 in the opposite direction, so that the first top groove 506 contacts the locking block 600 and achieves locking.

[0061] It is worth noting that the hinge of the locking block 600 is equipped with a certain amount of damping, and it can only deflect under the condition of additional external force.

[0062] Then, when the desired state is reached, the operator rotates the grip 301 forward again. At this time, the orientation angle of the locking block 600 remains unchanged. However, when the locking block 600 is moved close to the first protrusion 508 and the second protrusion 509, because the orientation of the locking block 600 forms an angle with the line connecting the first protrusion 508 and the second protrusion 509, the locking block 600 will be blocked by the first protrusion 508 and the second protrusion 509, resulting in a deflection towards the first protrusion 508. Then, the operator reverses the direction... Rotate the gripping part 301. At this time, because the protruding corner a of the locking block 600 is already in the storage groove 503, when the first connecting ring 302 rotates, the locking block 600 will be blocked by the connecting protrusion between the first top groove 506 and the storage groove 503, thus continuing to deflect. This causes the protruding corner b to face the first arc groove 504. Then, as the gripping part 301 continues to rotate, the locking block 600 enters the first arc groove 504, allowing the fourth contact electrode to contact the third contact electrode and achieve communication.

[0063] Preferably, this portable display screen is also equipped with a bracket that can be installed on an indoor wall. The bracket is equipped with a data connection cable and a charging cable. When the grip part 301 is close to the display screen, it can be installed with the bracket. Then, when the display screen is not in use, it can be placed on the bracket for charging or data transfer.
