Combine.
그리고 상기 하부암(100)의 타단에는 하부안착부(110)가 형성된다.A lower seating unit 110 is formed at the other end of the lower arm 100.
상기 하부안착부(110)는 하방향으로 오목하게 형성되어 상기 스프링(300)의 하부가 배치된다.The lower seating portion 110 is formed to be concave downward so that the lower portion of the spring 300 is disposed.
상기 하부안착부(110)의 중심부에는 결합돌기(111)가 돌출 형성되어 후술할 관통공(211)을 관통한다.A coupling protrusion 111 protrudes from the center of the lower seating part 110 to penetrate the through hole 211.
상기 결합돌기(111)는 도 5에 도시된 바와 같이 돌출부(112)와 절곡부(113)로 이루어진다.As shown in FIG. 5, the coupling protrusion 111 includes a protrusion 112 and a bent portion 113.
상기 돌출부(112)는 원통 형상으로 형성되어 상기 하부안착부(110)의 상면에서 상방향으로 돌출 형성된다.The protrusion 112 is formed in a cylindrical shape and protrudes upward from the upper surface of the lower seating part 110.

상기 절곡부(113)는 1개만으로 이루어질 수도 있으나 2개 이상으로 이루어짐이 바람직하다.The bent portion 113 may be made of only one, but preferably made of two or more.
본 실시예에서는 도 5 및 6(a)에 도시된 바와 같이 상기 절곡부(113)가 2개로 이루어져 상기 돌출부(112)의 상단에서 상호 반대 방향으로 절곡 형성되어 있다.In the present embodiment, as shown in FIGS. 5 and 6 (a), two bent portions 113 are formed to be bent in opposite directions from the upper ends of the protrusions 112.
상기 절곡부(113)는 상기 돌출부(112)에 하나만 형성될 경우 상기 하부암(100)과 상부암(200)의 결합시 상기 상부암(200)의 일측에만 걸리게 되어 상기 하부암(100)과 상부암(200)의 균형이 맞지 않아 상기 하부암(100)과 상부암(200)의 상대적 회전시 상호 뒤틀리거나 분리될 수 있다.When only one bent portion 113 is formed on the protrusion 112, when the lower arm 100 and the upper arm 200 are coupled to each other, only one side of the upper arm 200 is caught. When the upper arm 200 is not balanced, the lower arm 100 and the upper arm 200 may be distorted or separated from each other during relative rotation.
그리고 상기 절곡부(113)의 수가 증가할수록 상기 하부암(100) 또는 상부암(200)을 회전시킬 수 있는 회전 각도에 제한을 받게 된다.In addition, as the number of the bent portions 113 increases, the angle of rotation for rotating the lower arm 100 or the upper arm 200 is limited.
이에 따라 본 실시예에서는 2개의 절곡부(113)를 형성하여 상기 하부암(100)과 상부암(200)을 균형 있게 결합시키면서 180°이내에서 상기 하부암(100) 또는 상부암(200)의 회전 각도를 조절할 수 있다.Accordingly, in the present embodiment, two bent portions 113 are formed to balance the lower arm 100 and the upper arm 200 in a balanced manner, and thus, the lower arm 100 or the upper arm 200 of the lower arm 100 or the upper arm 200. The angle of rotation can be adjusted.
그리고 상기 하부안착부(110)의 외주면에는 하부돌출편(114)이 돌출 형성된다.The lower protrusion piece 114 protrudes from the outer circumferential surface of the lower seating part 110.
상기 하부돌출편(114)은 도 3 또는 도 4에 도시된 바와 같이 상기 하부안착부(110)의 외주면에서 일정 구간 형성된다.The lower protrusion piece 114 is formed in a predetermined section on the outer peripheral surface of the lower seating portion 110, as shown in FIG.
상기 하부돌출편(114)의 일단은 상기 하부암(100)과 상부암(200)의 상대적 회전 시, 후술할 상기 상부암(200)에 형성된 상부돌출편(216)의 일단과 접하여 상기 하부암(100)과 상부암(200)의 회전 각도를 일정 각도 이내로 저지한다.One end of the lower protrusion piece 114 is in contact with one end of the upper protrusion piece 216 formed on the upper arm 200 to be described later when the lower arm 100 and the upper arm 200 are rotated. Restrict the rotation angle of the 100 and the upper arm 200 within a predetermined angle.
즉, 도 2에 또는 도 6에 도시된 바와 같이 상기 하부돌출편(114)의 일단과 상기 상부돌출편(216)의 일단이 상호 접한 상태에서 상기 상부암(200)은 반시계 방향으로 회전하지 못한다.That is, as shown in FIG. 2 or FIG. 6, the upper arm 200 does not rotate in a counterclockwise direction when one end of the lower protrusion piece 114 and one end of the upper protrusion piece 216 are in contact with each other. can not do it.
또한, 상기 하부돌출편(114)은 후술할 상기 상부암(200)에 형성된 상부유동방지부(217)와 결합하여 상기 하부암(100)과 상부암(200)의 상하 유동을 방지한다.In addition, the lower protrusion piece 114 is coupled to the upper flow prevention portion 217 formed on the upper arm 200 to be described later to prevent the vertical flow of the lower arm 100 and the upper arm 200.
그리고 상기 하부돌출편(114)의 타단에는 상기 스프링(300)이 접하여 결합된다.And the other end of the lower protrusion piece 114 is coupled to the spring 300 in contact.
즉, 상기 스프링(300)은 후술하는 바와 같이 일단이 상기 상부암(200)에 결합되고 타단이 상기 하부돌출편(114)의 타단에 접하여 결합된다.That is, one end of the spring 300 is coupled to the upper arm 200 and the other end is coupled to the other end of the lower protrusion piece 114 as described below.
상기 스프링(300)은 타단이 상기 하부돌출편(114)의 타단에 접하여 상기 하부돌출편(114)의 일단과 상기 상부돌출편(216)의 일단이 접하도록 회전력을 부가한다.The spring 300 has a rotational force such that the other end is in contact with the other end of the lower protrusion piece 114 so that one end of the lower protrusion piece 114 and one end of the upper protrusion piece 216 contact each other.
그러나 전술한 바와 같이 상기 하부돌출편(114)의 일단과 상기 상부돌출편(216)의 일단은 상호 접하여 상기 상부돌출편(216)이 반시계 방향으로 더 회전하지 못한다.However, as described above, one end of the lower protrusion piece 114 and one end of the upper protrusion piece 216 are in contact with each other, and the upper protrusion piece 216 may not rotate further in the counterclockwise direction.
