<p>The present invention relates to a structure which is manufactured by the folding and attachment of paper and, more specifically, to a paper structure for a mechanism operation study using the operation of a gun barrel by including: a main body which has an opening formed to be able to see the inside; a support shaft which is installed to be rotatable inside the main body in order to protrude from the main body toward the upper side; a turret which is fixated on the upper end of the support shaft and has a penetration hole formed in the front side; an operation shaft which is installed to be extended downwards from the inside of the turret; the gun barrel which is combined by a hinge in order to rotate up and down in the upper end of the operation shaft and protrudes toward the outside through the penetration hole; a rotary shaft which is installed to be rotated by a rotary operation inside the main body; and a cam which supports the lower side of the operation shaft by being fixated on the rotary shaft, ascends and descends the operation shaft by rotating with the rotary shaft, and is installed to be seen from the outside through the opening. The present invention is able to: form an economical structure in an environmentally friendly manner by manufacturing a model using paper; be helpfully used for study by enabling a user to understand a mechanical operation by an easy operation; and increase study efficiency by performing an operation which raises interest by using the operation of the gun barrel.</p> |
