The warning device also comprises a warning mechanism 11, the warning mechanism 11 comprises a fixed rod 110, a bearing seat 111, a second transmission component 112, a straight gear 113, a rack 114, a fourth torsion spring 115, a guide plate 116, a warning plate 117, a seventh spring 118 and a striker 119, the fixed rod 110 is arranged at the upper part of the fixed rod 60, the fixed rod 110 is positioned above the support sleeve 61, the second rotating rod is rotatably arranged at the lower part of the fixed rod 110, the bearing seat 111 is arranged at the lower side of the front part of the left side of the backup plate 51, the bearing seat 111 is positioned above the fixed rod 60, the striker 119 is rotatably arranged at the left part of the bearing seat 111, the second transmission component 112 is arranged between the front side of the second rotating rod and the front side of the striker 119, the second transmission component 112 comprises two belt pulleys and one belt, the belt pulleys are arranged at the front sides of the second rotating rod and the striker 119, the belt is wound between the belt pulleys, the straight gear 113 is arranged at the middle part of the second rotating rod, the rack 114 is arranged at the left side of the support sleeve 61, the rack 114 is meshed with the straight gear 113, a fourth torsion spring 115 is arranged between the front part of the collision rod 119 and the front side of the bearing seat 111, a guide plate 116 is arranged at the lower part of the fixed column 60, a warning plate 117 is arranged on the right side of the guide plate 116 in a sliding mode, the warning plate 117 is matched with the collision rod 119, and three seventh springs 118 are uniformly arranged between the warning plate 117 and the guide plate 116 at intervals.

When a user puts a medicine bottle on the supporting sleeve 61, the medicine bottle drives the supporting sleeve 61 and the rack 114 to move downwards, the first spring 62 is compressed, the rack 114 drives the straight gear 113 and the second rotating rod to rotate, the second rotating rod drives the collision rod 119 to rotate through the second transmission component 112, the fourth torsion spring 115 deforms, when the collision rod 119 is separated from the warning plate 117, the seventh spring 118 restores to the original state, the warning plate 117 is driven to move rightwards to restore, then medicine injection can be performed on children, as the medicine in the medicine bottle is less and less, the first spring 62 restores to the original state, the supporting sleeve 61 and the rack 114 are driven to move upwards to restore, the rack 114 drives the straight gear 113 and the second rotating rod to reverse, the second rotating rod drives the collision rod 119 to reverse through the second transmission component 112 to restore, the original state of the fourth torsion spring 115 is restored, when the collision rod 119 is contacted with the warning plate 117, the warning plate 117 is driven to move leftwards, the seventh spring 118 is compressed, meanwhile, the warning board 117 can make a crisp sound, so that people are reminded that all the medicines in the medicine bottles are injected, and medical staff can help children to change medicines in time.
