또한, 도 7에 도시되는 바와 같이 상부커버(50a)와 하부커버(50b)를 포함해 커버 상단부를 누르면, 압축스프링(30)이 탄력적으로 압축되며 힌지부(20)의 회전핀(21)을 중심으로 회전하게 되어 상부커버(50a)와 하부커버(50b) 하단부가 벌어지게 되고, 눌렀던 부위를 놓으면 압축되었던 압축스프링(30)의 복원력에 의해 반대 방향으로 회전하게 되어 상부커버(50a)와 하부커버(50b)의 하단부가 원래 위치로 돌아가고, 압축스프링(30)의 탄발력에 준하는 압력으로 상부커버(50a)와 하부커버(50b)의 하단부 사이가 맞물리게 된다.In addition, as shown in FIG. 7, when the upper part of the cover including the upper cover 50a and the lower cover 50b is pressed, the compression spring 30 is elastically compressed and the rotation pin 21 of the hinge part 20 is pressed. The upper cover 50a and the lower cover 50b are rotated in the opposite direction by the restoring force of the compressed spring 30 when the pressed part is released, and the upper cover 50a and The lower end of the lower cover 50b returns to its original position, and the lower end of the upper cover 50a and the lower cover 50b is engaged with a pressure corresponding to the elastic force of the compression spring 30 .

따라서, 이러한 본 발명은 도 9에 도시되는 바와 같이 상부커버(50a)와 하부커버(50b)의 하단부 사이에 구동줄(1) 상단부가 고정되도록 하여, 어린이의 손이나 몸에 구동줄(1)이 닿지 않도록 하여 안전사고를 미연에 방지할 수 있다.Accordingly, the present invention is such that the upper end of the drive line (1) is fixed between the lower ends of the upper cover (50a) and the lower cover (50b) as shown in FIG. You can prevent accidents in advance by avoiding contact with them.
