The invention discloses a doffing mechanical arm on a spinning machine. The doffing mechanical arm comprises a drive device, a transmission assembly and a holding assembly. The drive device is connected with the lower end of a first lever of the transmission assembly. The upper end of the first lever is hinged to the lower end of a second lever through a transition plate. The upper end of the second lever is fixed with a cross-shaped shaft seat. A lengthwise shaft of a cross-shaped shaft is connected in a hole of the cross-shaped shaft seat in an inserted mode to form clearance fit. A horizontal shaft is fixed to the tail end of a swing arm, and the horizontal shaft penetrates through a horizontal axial hole in the cross-shaped shaft and is connected with the drive device through a horizontal joint pull rod. The tail end of the swing arm is connected with the drive device through a lengthwise joint pull rod. The holding part is arranged at the head end of the swing arm. As the drive device is controlled by an automatic control system, after the holding part is connected with a moving arm of a creel in a clamped mode, the holding part can move in three dimensions, namely in lengthwise direction, in horizontal direction and in a front-and-back mode under the drive of the transmission assembly. The reel will be driven along with the holding part to finish all actions needed in doffing. Thus, mechanical operation of automatic doffing is achieved and the working efficiency of the spinning machine is improved.
