A tent fixing pin cell for operating a mosquito repellent ultrasonic device using an oxidation-reduction reaction according to the present invention comprises: copper as a reduction electrode for reduction reaction； zinc as an oxidation electrode for oxidation reaction； soil filled in the tent fixing pin cell and acting as an electrolyte between the zinc and the copper； an electric wire through which electricity generated from the soil as an electrolyte, the zinc as an oxidation electrode, and the copper as a reduction electrode moves； a spiral joint part capable of separating a tent fixing pin to put the soil in the tent fixing pin cell； a ground contacting part for allowing the tent fixing pin cell to be fixed in the ground； and a mosquito repellent device generating mosquito repellent ultrasound by the electricity moved from the electric wire. As the natural soil is used, a small amount of electricity can be generated without using a battery. Therefore, the present invention can be used more easily. In addition, mosquito repellents that are now a necessity for campers are mostly sprayed or applied to the body. However, the mosquito repellents may have substances harmful to the body, and the substances can be dangerous, especially for children. If mosquitoes are eliminated by using the tent fixing pin for operating the device which generates electricity by the oxidation-reduction reaction and gives a frequency in a domain where the mosquitoes dislike, a user can enjoy pleasant camping which is more safe and harmless to the body by emitting only electromagnetic waves to a degree which is not harmful to humans.본 발명의 산화·환원 반응을 이용하여 모기퇴치초음파 장치를 작동시키는 텐트 고정핀 셀에 따르면, 환원 반응을 하는 환원 전극으로 구리와, 산화 반응을 하는 산화 전극으로 아연과, 텐트 고정핀 셀 내부에 채워지고 아연과 구리 사이의 전해질 역할을 하는 흙과, 전해질인 흙, 산화·환원 전극인 아연과 구리로 부터 생성되는 전기가 이동하는 전선과, 텐트 고정핀 셀 내부에 흙을 담을 수 있도록 텐트 고정핀을 분리할 수 있는 나선 접합부와, 텐트 고정핀 셀을 지면에 박을 수 있도록 하는 지면 밀첩부와, 전선으로 부터 이동된 전기에 의해 모기퇴치초음파를 발생시키는 모기퇴치장치를 포함한다.본 발명의 효과는, 자연의 흙을 이용함에 따라 건전지를 이용하지
