Abstract: The present application discloses a mannequin. The mannequin includes: a torso, upper limbs on both sides of the torso and a yawing device used for regulating the lateral swing of the upper limb being arranged at the joint between the upper limb and the torso. An upper limb fixing seat is arranged at the root of the upper limb. The yawing device includes: a yawing bracket hinged with the top of the upper limb fixing seat and a regulating piece with an inner end movable relative to the bottom of the yawing bracket. The outer end of the regulating piece being fixedly connected with the yawing bracket, and the movement of the regulating piece is used to drive the top of the upper limb fixing seat to swing relative to the yawing bracket, such that the upper limb is driven to swing.

Abstract: The present application discloses a mannequin. The mannequin includes: a support frame; plates, being configured to enclose the shell of the torso, and comprising driving plates; circumference regulating devices, being configured to support the driving plate and driving it to move; the torso comprising a plurality of regulating regions provided with the driving plates, the plates further comprising driven plates capable of moving together with the driving plates when driven by the driving plates, and at least one of the plurality of regulating regions is provided with the driven plate. Relaxation and contraction of the overall outline of the torso can be achieved simply by controlling the movement of the plates by transmission devices, and the size of the chest, waist, abdomen and hip circumferences of the mannequin can be adjusted, thereby accurately simulating the figure of the human body and achieving high adjustment accuracy.
