Multi-holder for learning

1. A multi-holder for learning, comprising:

a body;

the first device for folding a support unit hinge-coupled to one side of a lower part of the body to be rotatable around a hinge shaft, and folded in a longitudinal direction of the body or rotated and unfolded in a direction toward one side of a book or smart pad;

the second device for folding a support unit hinge-coupled to other side of the lower part of the body to be rotatable around a hinge shaft formed to be parallel with the hinge shaft, and folded in the longitudinal direction of the body or rotated and unfolded in a direction toward other side of the book or smart pad;

a folding floor plate device formed to be rotatable around a hinge shaft at a lower end portion of the body, and folded in the longitudinal direction of the body or unfolded in a rearward direction to erect and support the body; and

a fixing device configured to allow a height of the body to be adjustable by sliding in the longitudinal direction of the body and formed on the body to fix an upper part of the book or the smart pad having different heights,

wherein the body includes,

a rail formed to allow the fixing device to slide;

a first connector connected to the first device for folding a support unit and formed on a part of a left side of the body; and

a second connector connected to the second device for folding a support unit and formed on a part of a right side of the body,

wherein the fixing device includes,

a fixing head formed to fix the upper part of the book or smart pad;

a lifting bar linked with the first connector and the second connector and configured to slide on the rail; and

a fixing pin formed in a pin shape on a lower part the fixing head to fix a center of the upper part of the book, and a switch linked with the fixing pin to lift the fixing pin in an upward direction.

2. The multi-holder of the claim 1 , wherein the first device for folding a support unit and the second device for folding a support unit include:

a support part hinge-coupled to a hinge shaft with a spring to support rear parts of one side and other side of the book or smart pad to be rotatable around the hinge shaft, and folded in a longitudinal direction of the first device for folding a support unit or rotated and unfolded in an upward direction;

a holding device hinge-coupled to a hinge shaft with a spring to support lower parts of the one side and the other side of the book or smart pad and to be rotatable around the hinge shaft, and folded in the longitudinal direction of the first device for folding a support unit or rotated and unfolded in a forward direction; and

a coupler engaged with the first connector and the second connector.

3. The multi-holder of the claim 2 , wherein the support part is rotated and unfolded by spring in the upward direction when the first device for folding a support unit and the second device for folding a support unit are unfolded from the body.

4. The multi-holder of the claim 2 , wherein the holding device includes:

a press pin formed to be perpendicular to a longitudinal direction of the holding device and hinge-coupled to a hinge shaft with a spring to be rotatable around the hinge shaft, and folded into the holding device or rotated and unfolded in the upward direction; and

a groove portion formed at a center of the holding device such that the press pin is easily removed.

5. The multi-holder of the claim 2 , wherein the holding device receives an elastic restoring force to be folded by the springs of the first device for folding a support unit and the second device for folding a support unit to bind and hold one side of the book or smart pad due to elastic forces acting in directions toward the first device for folding a support unit and the second device for folding a support unit.

6. The multi-holder of the claim 1 , wherein:

a lower end portion of the lifting bar linked with the first connector and the second connector is hook-coupled to the coupler when the fixing device is located at a lower location; and

when the fixing device is moved in the upward direction, the first connector and the second connector are disconnected from the coupler so that the first device for folding a support unit and the second device for folding a support unit are unfolded toward both sides of the multi-holder.
