The push rod 130 may be formed as a square hollow member or may be formed to have a rectangular parallelepiped shape. Here, the rectangular parallelepiped may include a structure in which one side is opened.

The striking member 140 is coupled to the sliding hole 113 formed on the upper surface of the main body 110 so as to be movable up and down below the head 122 to move the push rod 130 along the longitudinal direction of the hammer 120. [ And may be vertically installed so as to be parallel to the push rod 130. The striking member 140 is lifted by the second cam 170 to be described later and is moved from the head 122 of the hammer 120 which has been rotated to the maximum by the push rod 130 It can be installed so as to be spaced downward. On the other hand, the head striking member 140 may be adhesively attached to the upper end of the head portion 141 having a width or diameter larger than the width or diameter of the head 122.

The first and second cams 160 and 170 are provided inside the main body 110 with a rotation shaft 150 rotated by a rotation operation so as to raise and lower the push rod 130 and the striking member 140, Respectively, and are installed so as to be visible from the outside through the opening 111. The first and second cams 160 and 170 may be formed in a plate shape and each of the discontinuous portions 161 and 171 is formed to have a sudden change in radius. 162 and 172 may be fixedly attached to the outer surface of the rotary shaft 150 with an adhesive.

The first and second cams 160 and 170 have various configurations of hitting the striking member 140 by the hammer 120 so that the phase of the discontinuities 161 and 171 on the rotation axis 150 For example, 180 degrees, and may have a shape in which the radius gradually increases or decreases with respect to the discontinuous portions 161 and 171. [

The rotary shaft 150 may be installed horizontally so as to be rotatable in the shaft coupling hole 114 formed on both sides of the main body 110 by protruding both ends from the main body 110 as in the present embodiment, And one end protruding from the main body 110 is inserted into the insertion hole of the rotary plate 151 and attached to the attachment portion 153 extended to be folded inside the insertion hole of the rotary plate 151 with an adhesive And the other end projecting from the main body 110 may be attached to the attachment portion 154 which is inserted into the insertion hole of the operation plate 152 and extended so as to be folded inside the insertion hole of the operation plate 152.

의 단면 형태를 가지도록 형성되고, 본체(110)의 양측에 형성되는 개구(111)를 통해서 본체(110) 내로 삽입되어 양단에 형성되는 걸림부(191)가 본체(110)의 상면에 걸린 상태로 부착되며, 피타격부재(140)가 중심부의 삽입홀(미도시)에 삽입되고, 이러한 삽입홀의 내측에 접히도록 연장 형성되는 부착부(192)가 피타격부재(140)에 부착되어 고정된다. The first and second restoring members 180 and 190 are respectively installed on the main body 110 to provide a restoring force for lowering the push rod 130 and the striking member 140, respectively. Here, the first restoration member 180

And the engaging portions 181 formed at both ends of the engaging portion 181 are inserted into the main body 110 through the openings 111 formed at both sides of the main body 110 and are engaged with the upper surface of the main body 110 And the push rod 130 is inserted into an insertion hole (not shown) at the center and the attachment portion 182 extended to be folded inside the insertion hole is attached and fixed to the push rod 130. Also, the second restoring member 190

And the engaging portions 191 formed at both ends of the engaging portion 191 are inserted into the main body 110 through the openings 111 formed at both sides of the main body 110 and engaged with the upper surface of the main body 110 And a striking member 140 is inserted into an insertion hole (not shown) at the center and an attaching portion 192 extending to be folded inside the insertion hole is attached and fixed to the striking member 140 .

Each of the first and second restoring members 180 and 190 is configured such that each of the push rod 130 and the striking member 140 is engaged with the first and second restoring members 180 and 190 in a state where both ends of the first and second restoring members 180 and 190 are fixed to the upper ends of the main body 110, The push rod 130 and the striking member 140 are deformed when the lower end of the push rod 130 and the striking member 140 are fixed by the two cams 160 and 170, When the pressing force applied from each of the first and second cams 160 and 170 is released, the deformed portion is restored downward, thereby moving each of the push rod 130 and the striking member 140 downward. 3, when the push rod 130 is lifted by the first cam 160, the lower portion of the first restoring member 180 is moved in the upward direction By this deformation, the pushing force by the first cam 160 causes the push rod 130 to descend upon releasing. The action of the first restoring member 180 is applied to the second restoring member 190 as well.

Hereinafter, the operation of the paper workpiece for learning the operation of the apparatus using the hammer operation according to one embodiment of the present invention will be described.

As the first and second cams 160 and 170 rotate, the push rod 130 rises to move the stick 121 upward (as shown in FIG. The pusher member 140 is lifted and the push rod 130 and the striking member 140 are moved by the first and second restoring members 180 and 190, respectively, The hammer 120 is lowered to lower the striking member 140 into the main body 110, thereby learning the operation of the cam mechanism. Herein, the temporal priority is not necessarily determined for the upward and downward movements of the push rod 130 and the striking member 140, and the operation of pushing the striking member 140 to the main body 110 by the descent of the hammer 120 It is needless to say that it is possible to have various time sequences according to the phase difference between the discontinuous portions 161 and 171 of the first and second cams 160 and 170. For example, The operation of pivoting the striking member 140 will be described.

As shown in Fig. 4, as the rotary shaft 150 rotates together with the first and second cams 160 and 170 by the rotation operation of the operation plate 152, the first cam 160 is pressed upward by the first cam 160 The push rod 130 is lifted up and the striking member 140 which is pressed upward by the second cam 170 rises after the push rod 130 rises or rises. At this time, the striking member 140 is spaced apart from the head 122 of the hammer 120, which is rotated upward to the maximum when the striking member 140 is maximally raised.

As shown in FIG. 5, as the rotation shaft 150 rotates together with the first and second cams 160 and 170 by the continuous rotation operation of the operation plate 152, the first cam 160 rotates upward The push rod 130 whose pushing force is released is moved downward by the first restoring member 180 so that the hammer 120 rotates downward due to its own weight, The hitting member 140 is released by the cam 170 and the hitting member 140 is lowered by the second restoring member 190 so that the hammering member 120 is positioned within the main body 110 So that an operation of striking and collapsing is performed.

As shown in FIG. 6, as the rotary shaft 150 continues to rotate together with the first and second cams 160 and 170 by the continuous rotation operation of the operation plate 152, So that the hammer 120 rotates upward and is returned. Simultaneously with the return of the hammer 120 or the return of the hammer 120, the striking member 140 is also returned to the upper side by the second cam 170.

According to the paper workpiece for learning the operation of the apparatus using the hammer operation according to the present invention, it is possible to make the model work using the paper, so that the eco-friendly and economical work can be performed. And by using the motion of the hammer, it is possible to improve the learning efficiency due to the implementation of the motion causing interest.
