Three. the utility model content

The utility model purpose: be anchored on the not injury that causes of easy damaged desk, simple, with low cost, easy accessibility, reduction myopia prevention equipment of an edge for vast student provides a kind of, when keeping the student to learn sitting posture rectify lastingly, make glasses and books keep a normal chi distance, reach the purpose of pre-myopia prevention, spinal curvature.

Specific embodiments of the present utility model: a kind of collapsible pre-myopia prevention gesture rectify rack includes: base, rotating basis, rotation control mechanism, sleeve vertical rod, hook knob, lifting vertical rod and the Lower jaw support of clamp nut contained in side, the place ahead horizontal groove and below.

The base side has level " U " shape groove, top or rear end to be connected with rotating basis; Contain the fixedly fastening bolt of usefulness in the lower lip of base level " U " shape groove; Rotation control mechanism crosses between the top of rotating basis and the combination of sleeve vertical rod bottom, and by the anglec of rotation above the folding control of gear and spring; The lifting vertical rod is through in the sleeve vertical rod, and controls its height by locking knob; The lifting rod end has the Lower jaw support that can do the certain angle rotation.

Sleeve can be straight-bar, and that shape can be is square, circular, oval, triangle, trapezoidal or polygon and other shape, on have locking knob control to have suffered the height of product; Lower jaw support can be sphere, arc, multiaspect in conjunction with arc, ellipse, olive ball-type and other multiple shape, and its material can be flexible elastic material or hard material.
