Specifically, the support shaft portion 421 can be supported on the inner wall surface of the arc-shaped slot 411 so that the second connecting member 42 can support the first connecting member 41, and when the arc-shaped slot 411 rotates around the support shaft portion 421, the support shaft portion 421 can continuously support the arc-shaped slot 411. The state that the "LED screen body 10 can be flipped outward to a state in which the first connecting member 41 can be separated from the second connecting member 42" refers to a state in which the LED screen body 10 is flipped outward to a state in which the upper end of the LED screen body 10 does not interfere with the LED screen body above it, and at this time, the LED screen body 10 is moved obliquely upward so that the support shaft portion 421 can exit from the opening of the arc-shaped slot 411 to separate the first connecting member 41 from the second connecting member 42.

6. The LED display screen according to any one of claims 1 to 5, characterized in that, The second connection structure (50) includes a pin seat (51) and a locking pin (52). One of the pin seat (51) and the locking pin (52) is disposed on the upper end of the LED screen body (10), and the other of the pin seat (51) and the locking pin (52) is disposed on the first mounting base (20). When the second connection structure (50) is in the connected state, the locking pin (52) extends into the pin seat (51) to connect the upper end of the LED screen body (10) and the first mounting base (20). When the second connection structure (50) is in the disassembled state, the locking pin (52) exits from the pin seat (51) to separate the upper end of the LED screen body (10) from the first mounting base (20).

7. The LED display screen according to claim 6, characterized in that, The locking pin (52) includes a mounting housing (521), a pin (522), and a limiting member (523). The pin (522) is movably disposed within the mounting housing (521) and can extend out of the mounting housing (521). The pin (522) has a retracted state and an extended state. The limiting member (523) is movably disposed within the mounting housing (521) and has a mating state that engages with the pin (522) and a disengaged state that disengages from the pin (522). When the pin (522) is in the retracted state, the limiting member (523) is in the mating state so that the pin (522) remains in the retracted state. When the limiting member (523) switches from the mating state to the disengaged state, the pin (522) can switch from the retracted state to the extended state.

8. The LED display screen according to claim 7, characterized in that, The locking end of the pin (522) can extend into the pin seat (51) and has a limiting groove (524). The limiting member (523) includes a movable limiting plate (5231) and a spring member (5232). The limiting plate (5231) can be engaged in the limiting groove (524). When the pin (522) switches from the extended state to the retracted state, The limiting plate (5231) is engaged in the limiting slot (524) under the action of the spring (5232), so that the limiting member (523) is in the engagement state, thereby keeping the pin (522) in the retracted state.

9. The LED display screen according to claim 8, characterized in that, The mounting housing (521) has a clearance opening (5211), and the limiting member (523) further includes a trigger protrusion (5233) that can extend out of the clearance opening (5211). The trigger protrusion (5233) is connected to the limiting plate (5231). When the pin (522) is in the retracted state, the trigger protrusion (5233) extends out of the clearance opening (5211). When the trigger protrusion (5233) is triggered, the limiting plate (5231) moves to disengage from the limiting slot (524), thereby causing the limiting member (523) to switch to the disengaged state, and causing the pin (522) to switch from the retracted state to the extended state under the action of the spring member (5232).

10. The LED display screen according to claim 6, characterized in that, The LED screen (10) includes a screen body (12) and a control box (13) disposed on the rear side of the screen body (12). The control box (13) is disposed on the upper end of the screen body (12), and the pin seat (51) is disposed on the control box (13).
