The first and second expansion plates 153 and 163 may be formed of a single plate and a plurality of plates may be stacked to increase the weight to facilitate the downward movement of the first and second movable shafts 150 and 160.

The first and second barrels 170 and 180 are hinged to be rotatable up and down on the upper ends of the first and second movable shafts 150 and 160 and protrude outward through the first and second through holes 141 and 142, And can be projected in a nearly horizontal state. In addition, the first and second barrels 170 and 180 may be formed as rectangular hollow members, but the present invention is not limited thereto.

The rotary shaft 190 is installed to rotate inside the main body 110 by rotating operation. For example, the rotary shaft 190 is rotatably supported by the main body 110 through a shaft coupling hole 116 of the main body 110, And both sides protruding from the main body 110 are inserted into the insertion holes of the first and second rotation plates 191 and 192 so that the first and second rotation plates 191 and 192 And the end protruding from the main body 110 is inserted into the insertion hole of the operation plate 195 and is extended to be folded in the insertion hole of the operation plate 195. The main body 110 is attached to the third and fourth attachment portions 193 and 194, And can be attached and fixed to the operation plate 195 by the fifth attachment portion 196 formed.

First and second shake limiting members 230 and 240 may be installed inside the first and second support shafts 120 and 130, respectively. Here, the first and second shake limiting members 230 and 240 are disposed in the vicinity of the first and second movable shafts 150 and 160, respectively, by inserting the first and second movable shafts 150 and 160, respectively, Respectively, so as to limit the lateral shaking of the first and second movable shafts 150 and 160. The first and second shake limiting members 230 and 240 can limit the vertical movement of the first and second movable shafts 150 and 160 and the movement of the first and second movable shafts 150 and 160 by limiting the lateral shake of the first and second movable shafts 150 and 160, The first and second expansion plates 153 and 163 are guided so as to smoothly move up and down on the first and second cams 210 and 220. For example, A plurality of ninth and tenth attachment portions 231 and 241 extending so as to fold the edges can be fixedly attached to the inside of the first and second support shafts 120 and 130 respectively with an adhesive, Third and fourth insertion holes 232 and 242 may be respectively formed to insert the movable shafts 150 and 160, respectively. The third and fourth insertion holes 232 and 242 have a size such that the first and second movable shafts 150 and 160 can freely slide, respectively. The first and second insertion shafts The degree of clearance with the two movable shafts 150 and 160 may be different.

The first and second cams 210 and 220 are fixed to the rotary shaft 190 to support the lower sides of the first and second movable shafts 150 and 160 and rotate together with the rotary shaft 190 to rotate the first and second movable shafts 150, and 160, respectively. The first and second movable shafts 150 and 160 are provided to be seen from the outside through the opening 111, and have different radii, thereby varying the height of the first and second movable shafts 150 and 160, respectively . The first and second cams 210 and 220 are provided with seventh and eighth attachment portions 211 and 221 extending to be folded in the insertion hole (not shown) into which the rotation shaft 190 is inserted, And can be fixed. On the other hand, the first and second movable shafts 150 and 160 can be lowered by their own loads and the loads of the first and second barrels 170 and 180 when they are lowered.

3 to 6, when the first and second cams 210 and 220 are rotated together with the rotation shaft 190 as in the present embodiment, the first and second movable shafts 150 and 160 are alternately raised and lowered The maximum radius of each of them can be fixed to the rotation axis 190 so as to be opposite to each other.

Hereinafter, an operation of the paper workpiece 100 for learning the operation of the apparatus using the alternating operation of barrel according to one embodiment of the present invention will be described as an example.

According to the present invention, as the first and second cams 210 and 220 are rotated by the rotation of the rotating shaft 190, the first and second movable shafts 150 and 160 are rotated by the first and second cams 210 and 220 And the first and second barrels 170 and 180 are guided by being engaged with the first and second through holes 141 and 142, respectively. The first and second movable barrels 170 and 180 move up and down, 150, and 160, so that the operation of the cam mechanism can be learned by performing the shooting operation of the gun. Such operation will be described in detail with reference to the drawings.

3, the rotating shaft 190 is rotated together with the first and second cams 210 and 220 by the rotating operation of the operating plate 195 (shown in Figs. 1 and 2), whereby the first cam 210 The first movable shaft 150 is moved upward so that the first barrel 170 is moved to the first through hole 141 and the second barrel 150 is moved upward, So that the posture of the envelope can be expressed by maintaining the posture from horizontal to near the posture. At this time, the portion of the second cam 220 having a small radius supports the second movable shaft 160, so that the second movable shaft 160 moves downward relative to the first movable shaft 150 due to the load, The second barrel 180 is supported in a state of being hooked on the second through-hole 142 so that its end is inclined upward, and the posture of the second barrel 180 is moved by the reaction The operation is expressed. The first and second movable shafts 150 and 160 are restricted in the lateral movement of the first and second movable shafts 150 and 160 by the first and second shake limiting members 230 and 240 so that the first and second movable shafts 150 and 160 move up and down, 2 rotation of the barrels 170 and 180 is smoothly performed.

4, the first and second movable shafts 150 and 160 are supported by the first and second cams 210 and 220 at a small radius by the continuous rotation of the rotating shafts 190, Is located at a descending height as the second movable shaft 160 so that the first barrel 170 is inclined such that its end is directed upward as in the case of the second barrel 180, thereby expressing the post-wrapping operation .

5, the first movable shaft 150 is supported by the first cam 210 at a small radius by the continuous rotation of the rotating shaft 190, so that the first barrel 170 is maintained in a tilted state While the second movable shaft 160 is lifted up by supporting the second camshaft 160 at a portion having a large radius at the second cam 220 so that the second barrel 180 is caught by the second through- Express the state before launch.

6, the first and second movable shafts 150 and 160 are supported by the first and second cams 210 and 220 at a small radius by the continuous rotation of the rotating shaft 190, Is located at a descending height as in the first movable shaft 150 so that the second barrel 180 is inclined such that its end is directed upward like the first barrel 170 to express the post-wrapping operation .

According to the apparatus work learning paper work 100 using the barrel shift operation according to the present invention, as the first and second cams 210 and 220 are rotated, the first and second movable shafts 150 and 160 move up and down, And the first and second barrels 170 and 180 rotate up and down about the hinge-coupled portions of the first and second movable shafts 150 and 160, that is, the first and second hinge shafts 152 and 162, So that the operation of the cam mechanism can be learned through the opening 111 by performing the shooting operation of the gun. Therefore, according to the present invention, by making it possible to make a model using paper, eco-friendly and economical work can be performed, and the machine operation can be understood easily by easy operation, so that it can be usefully used for learning. The learning efficiency can be increased due to the implementation of the operation that induces the interest, and the pair of barrels can be operated alternately with each other, so that the understanding of the cam operation can be enhanced and the interest can be further improved.
