제1 삽입구(301a)의 내경(D2)은 제1 축(100)의 일단부(100a)의 외경(D1) 보다 크다. 이에 따라, 제1 축(100)의 일단부(100a)가 제1 부분(301)의 제1 삽입구(301a)에 삽입될 수 있으며, 제1 부분(301)은 제1 축(100)을 중심으로 회전할 수 있다.The inner diameter D2 of the first insertion opening 301a is larger than the outer diameter D1 of the one end portion 100a of the first shaft 100. Accordingly, one end portion 100a of the first shaft 100 may be inserted into the first insertion hole 301a of the first portion 301, and the first portion 301 may be centered on the first shaft 100. Can rotate.
제2 부분(302)은 제1 부분(301)에 결합된 힌지축(303)에 피봇 가능하게 결합되며, 제2 축(200)의 일단부(200a)가 끼움 결합된다. 이에 따라, 제2 부분(302)은 힌지축(303)을 중심으로 피봇하여(도 9의 R 방향) 제2 축(200)이 제1 축(100)과 포개어 질 수 있다.The second portion 302 is pivotally coupled to the hinge shaft 303 coupled to the first portion 301, and one end 200a of the second shaft 200 is fitted. Accordingly, the second portion 302 is pivoted about the hinge axis 303 (in the R direction of FIG. 9) so that the second axis 200 can be superimposed with the first axis 100.
그라인더 장착부재(400)는 제2 축(200)에 연결됨으로써 제1 축(100)을 중심으로 회전할 수 있다. 이에 따라 그라인더(G, 도 7 참조)와 같은 통상의 절단장치가 그라인더 장착부재(400)에 장착된 상태에서 그라인더 장착부재(400)가 제1 축(100)을 중심으로 회전함으로써, 제1 축(100)을 중심으로 회전하는 그라인더(G)를 통해 작업면(S)에 원형의 개구를 용이하게 타공할 수 있다. 그라인더(G)는 통상의 기술과 동일하거나 유사하므로 이에 대한 설명은 생략하겠으며, 그라인더 장착부재(400)의 구체적인 구조에 대해서는 후술한다.The grinder mounting member 400 may be rotated about the first shaft 100 by being connected to the second shaft 200. Accordingly, the grinder mounting member 400 rotates about the first shaft 100 in a state in which a conventional cutting device such as grinder G (see FIG. 7) is mounted on the grinder mounting member 400. Through the grinder G which rotates about 100, a circular opening can be easily perforated in the working surface S. FIG. Since the grinder G is the same as or similar to the conventional technology, a description thereof will be omitted, and a detailed structure of the grinder mounting member 400 will be described later.

Combined.
제1 고정부재(500)는 제1 축(100)의 일단부(100a)에 결합되어 작업면(S)과 맞닿는다.The first fixing member 500 is coupled to one end portion 100a of the first shaft 100 to contact the working surface S.
구체적으로, 제1 고정부재(500)는 삽입부(501), 제1 지지면(502), 고정핀(503)을 포함한다.In detail, the first fixing member 500 includes an insertion part 501, a first support surface 502, and a fixing pin 503.
삽입부(501)는 제1 삽입구(301a)의 내경(D2)보다 작은 외경(D4)으로 형성되어, 제1 삽입구(301a)에 삽입된다. 삽입부(501) 내부에는 제1 축(100)의 일단부(100a)의 외경(D1) 보다 큰 내경(D3)을 가지는 제2 삽입구(501a)가 형성된다. 이에 따라, 삽입부(501)가 제1 삽입구(301a) 내에 삽입된 상태에서, 제1 축(100)의 일단부(100a)가 제2 삽입구(501a) 내로 삽입된다.The insertion part 501 is formed with an outer diameter D4 smaller than the inner diameter D2 of the first insertion hole 301a and is inserted into the first insertion hole 301a. Inside the insertion portion 501, a second insertion hole 501a having an inner diameter D3 larger than the outer diameter D1 of the one end portion 100a of the first shaft 100 is formed. Accordingly, one end portion 100a of the first shaft 100 is inserted into the second insertion hole 501a while the insertion portion 501 is inserted into the first insertion hole 301a.
또한, 삽입부(501)가 제1 삽입구(301a) 내에 끼움 결합되는 경우, 제1 고정부재(500) 및 연결부재(300)는 제1 축(100)을 중심으로 일체로 회전할 수 있다.In addition, when the insertion part 501 is fitted into the first insertion hole 301a, the first fixing member 500 and the connection member 300 may be integrally rotated about the first axis 100.
아울러, 제1 축(100)의 일단부(100a)의 외경(D1)은 제2 삽입구(501a)의 내경(D3) 보다 작기 때문에, 일단부(100a)의 외경(D1)과 제2 삽입구(501a)의 내경(D3) 간의 유격을 통해, 연결부재(300) 및 제 1 고정부재(500)가 고정된 제1 축(100)을 중심으로 일체로 회전할 수 있다.In addition, since the outer diameter D1 of the one end portion 100a of the first shaft 100 is smaller than the inner diameter D3 of the second insertion hole 501a, the outer diameter D1 of the one end portion 100a and the second insertion hole ( Through the clearance between the inner diameter (D3) of the 501a, the connecting member 300 and the first fixing member 500 can be integrally rotated around the fixed first shaft (100).
