Wherein, the two ends of the cross rod 4 are respectively fixed with a vertical column 5, the vertical column 5 is vertical to the cross rod 4, and the lower end of the vertical column 5 is fixed with the ground. The horizontal bar 4 and the upright post 5 are inherent parts of gymnastic apparatus, and two rolling bearings are sleeved in the middle of the horizontal bar 4 and are respectively marked as a first rolling bearing and a second rolling bearing. The inner rings of the first rolling bearing and the second rolling bearing are fixedly connected with the cross rod 4 at a certain distance (the distance between the two hands is equal to that when the first rolling bearing and the second rolling bearing are specifically adjusted according to needs or grabbed and lifted by two arms of an adult human body); a first connecting arm is fixed on the outer ring of the first rolling bearing, and a second connecting arm is fixed on the outer ring of the second rolling bearing. The lowest ends of the first connecting arm and the second connecting arm are connected, the two connecting arms 2 are respectively connected in series (the middles of the two ends of the connecting arms 2 are connected in series) with force-sensitive sensors 8, the other ends of the two connecting arms are connected in a U shape, and the bottoms of the U-shaped parts are serially arranged in guide grooves 10 of the simulated human body 1 and can slide in the guide grooves 10. The upper part of the simulated human body 1 is provided with a guide groove 10, and the bottoms of the first connecting arm and the second connecting arm are serially arranged in the guide groove 10. The fixed position of the electromagnetic chuck 9 is adapted to the horizontal position of the simulated human body, namely when the simulated human body 1 is positioned at the highest position, the electromagnetic chuck 9 just sucks the simulated human body.
