Self-adaptive positioning magnetic hoisting mechanism

The utility model discloses a self-adaptive positioning magnetic hoisting mechanism which comprises a grabbing unit, a connecting unit and a driving unit, and the grabbing unit is used for grabbing materials; the connecting unit comprises a connecting rod piece and a limiting piece, the connecting rod piece is provided with an upper end and a lower end, the limiting piece is arranged at the upper end of the connecting rod piece, and the grabbing unit is arranged at the lower end of the connecting rod piece; an output shaft of the driving unit can abut against the limiting piece so that the connecting unit can be pushed to move upwards in the extending process of the output shaft. The connecting unit falls down through gravity in the retraction process of the output shaft. The pneumatic conveying mechanism at least has the following advantages that the gravity of an object and the reverse installation mode of the air cylinder are combined, it is guaranteed that material carrying is completed, and meanwhile bea
