The unlocking mechanism can unlock the latch 11 from the latch 31. The unlocking mechanism is provided with a deflector rod 4, and the first end of the deflector rod is hinged with the turnover plate 2; the ratchet plate is provided with a chute 32, and the second end of the deflector rod is provided with a sliding shaft 41 capable of sliding in the chute 32. The first end of the deflector rod is also provided with a handle 42, the deflector rod is stirred by the handle 42, the sliding shaft 41 at the second end of the deflector rod slides in the sliding groove 32 to drive the ratchet plate to turn over, so that the clamping column 11 is separated from the clamping teeth 31 to realize unlocking, the turnover plate 2 is turned over, and other angles are changed. After the angle is determined, the handle 42 is released, the ratchet plate swings under the action of the tension spring 7, the clamping column 11 is clamped into the clamping teeth 31, and the turnover plate 2 locks the angle stably under the action of gravity. The overturning angle of the overturning plate 2 is locked through the latch 31 of the ratchet plate, so that the panel can be stably locked at all angles while the panel is changed in angle, and the locking failure is prevented.
