When the box connecting seat 16 is connected to the LED box frame, even if the LED box frame is arc-shaped, the connection of the LED box can still be achieved. When the corresponding box connecting seats 16 are respectively connected to the two LED frames, the adjusting rod 11 is rotated, the adjusting rod 11 drives the adjusting gear 12, the adjusting gear 12 drives the first rack 18 and the second rack 20 through the teeth, the first rack 18 drives the first sliding seat 17, the second rack 20 drives the second sliding seat 19, the first sliding seat 17 and the second sliding seat 19 respectively drive the box connecting seat 16, so that the angle between the two LED box frames can be quickly adjusted, which is convenient for use and simple to operate.

The first limiting beads 34 and the second limiting beads 36 are both located in the cylindrical grooves and contact the inner walls of the cylindrical grooves through elastic members. The elastic members push the first limiting beads 34 and the second limiting beads 36. When the first limiting beads 34 and the second limiting beads 36 are subjected to thrust, they move toward the middle of the mounting seat 13 and the limiting plate 21. The elastic member can be a spring.

[0029] In one embodiment, the first limiting bead 34 is located inside the first limiting ring 35, and the second limiting bead 36 is located inside the second limiting ring 37.

When it is necessary to adjust the angle of the LED box frame, the adjusting rod 11 is rotated, and the adjusting rod 11 drives the two adjusting gears 12 located at the end to rotate. Since the adjusting gear 12 is meshed and connected with the first rack 18 and the second rack 20, the adjusting gear 12 drives the first rack 18 and the second rack 20 respectively through the teeth, and the first rack 18 and the second rack 20 move in the direction away from each other, the first rack 18 drives the first sliding seat 17, the second rack 20 drives the second sliding seat 19, and the first sliding seat 17 and the second sliding seat 19 respectively drive the box connecting seat 16, so that the angle between the two LED box frames can be quickly adjusted. The invention can be quickly adjusted, thereby facilitating use, solving the problems that the arc of the conventional arc box cannot make a smooth transition and the arc fillet diameter is too large, and the operation is simple. During the movement of the first sliding seat 17 and the second sliding seat 19, the limit bead is pressed into the cylindrical groove, and as the first sliding seat 17 and the second sliding seat 19 continue to move, the limit bead enters the limit hole under the push of the internal spring, and then the position of the first sliding seat 17 and the second sliding seat 19 can be limited by the first limit bead 34 and the second limit bead 36, and by referring to the observation window 14 and the scale line 15, the displacement distance of the first sliding seat 17 and the second sliding seat 19 can be accurately controlled, thereby accurately controlling the angle between the two LED box frames, and in the process of taking, the arc-shaped protective rod 31 can play an anti-collision effect to avoid damage.
