The utility model relates to the field of water dripping wheels, in particular to a
clutch push plate automatic reset
safety control device which comprises a water dripping wheel shell. The
clutch push plate further comprises a shifting block, a
metal sheet, a through groove, a
clutch push plate body, a limiting seat, a torsional spring, a reaction bird sheet, a positioning seat and a reaction gear, the shifting block is slidably connected to the front side of the water dropper shell, the
metal sheet is inserted into the top surface of the shifting block, the through groove is formed in the position, corresponding to the
metal sheet, in the water dropper shell, and the
metal sheet penetrates through the through groove to be connected with the clutch push plate body. Through the arrangement of the shifting block, when the shifting block is pressed down, the reaction bird piece smoothly slides into a tooth groove of the reaction gear, after the clutch
stroke reaches two thirds of the rotation angle, the reaction bird piece enters a critical state, however, due to the fact that the two moving points both pass through the connecting line of the two points, the whole clutch can rotate anticlockwise, and therefore the clutch can rotate anticlockwise. And the critical point of the reaction bird piece loses
efficacy, and the reaction bird piece smoothly slides into the tooth groove of the reaction gear, so that limiting clamping is realized.
