Detailed Description

The following description will explain embodiments of the present invention with reference to the drawings. As shown in fig. 1 to 4: a spring piece type multilayer high-precision material rack comprises a bottom plate 1, wherein a supporting frame 2 is fixedly arranged on the bottom plate 1, two material guide plates 3 are symmetrically arranged on the bottom plate 1, the material guide plates 3 are matched with openings at the side of the supporting frame 2, a plurality of supporting mechanisms which are longitudinally stacked and distributed are arranged on the supporting frame 2,

the supporting mechanism comprises swinging bodies 5 rotatably supported on a supporting frame 2 through swinging supporting shafts 4, a positioning plate 6 is arranged on each swinging body 5, a driving shaft 7 is also arranged on each swinging body 5, the end part of each driving shaft 7 is connected in an arc-shaped groove 8 formed in the side wall of the supporting frame 2 in a sliding mode, two swinging bodies 5 are connected between adjacent supporting mechanisms through connecting pieces 9, the top end of each connecting piece 9 is directly hinged with the driving shaft 7, close to the upper swinging body 5, of each swinging body 5, the bottom end of each connecting piece 9 is provided with a long groove 10, the end part, close to the driving shaft 7 of the lower swinging body 5, of each swinging body 5 is connected in the long groove 10 in a sliding mode, and a torsion spring is further arranged at the position, close to the swinging supporting shaft 4, of each supporting.
