The present invention is related to the pick up, and more specifically, it is an improvement plan of Utility Model Registration No. 20-0446698. The extension connecting bar is coupled when the upper and lower cases are coupled by coupling the extension connecting bar whose spring is extended from the coil and whose end is connected to the negative terminal of the circuit board to the inner wall of the inner space formed by the coupling of the upper case and the lower case. It can be easily smuggled and flown, but the economical efficiency of the product is reduced due to the process of joining the extension connection bar to the inner wall of the inner space, that is, the additional process that occurs during fusion and adhesion. The contact surface of the connection bar is also reduced, resulting in poor contact with the bulb. The present invention for achieving the above object is to fix the circuit board to which the lamp is coupled to the upper part of the inner space that the first body, the O-ring and the second body is coupled to the outside and sealed to the outside and the above circuit in the lower portion of the inner space The battery is built in such a manner that the positive electrode contacts the positive terminal of the substrate, and the coil part contacting the negative electrode of the battery is connected to the connecting bar, and the connecting bar extends in the direction of the circuit board and has an extension connecting bar which connects to the negative terminal of the circuit board. In the connection bar is inserted into the insertion groove formed in the inner wall and the upper portion of the connection bar is formed with a bent portion, the connection bar holder provided at the end of the bent portion is inserted into the fixing groove is fixed.본 고안은 집어등에 관한 것으로 구체적으로는 실용신안등록 20-0446698 호의 개량고안이다. 스프링이 코일로부터 연장되어 끝단이 회로기판의 음극단자에 접속되는 연장 접속바를 유동가능하게 상부 케이스와 하부케이스의 결합으로 이루어지는 내부 공간의 내측벽에 결합함에 따라 상, 하부케이스를 결합시 연장 접속바가 유동 되어 쉽게 밀찰 결합할 수
