This invention relates to a sickle that is easy to replace. The housing 1a is formed by folding an iron plate so that the upper and lower support plates 11 and 11 'and the insertion grooves 1b' And a locking protrusion 13 is formed at the rear end of the insertion groove 12 of the lower support plate 11 so as to prevent the disposable blade 1b from being pushed back. The upper and lower support plates 11 and 11 'are formed with grooves 15 for guiding the upper and lower support plates 11 and 11 to be opened or closed as the locking pieces 14 are fitted or released, The lock piece 14 is rotated using a tool such as a screwdriver or a coin to form a lock projection 16 for fixing or disassembling the disposable blade 1b. The disposable blade 1b is provided on both sides of the back portion A locking piece rotating groove 18 for allowing the opening 17 and the locking piece 14 to rotate at the same intervals as the intervals of the locking pieces 14 Is formed at a right angle to the inner side surface of the locking piece turning groove 18, that is, one side line of the opening portion 17, and is formed with a locking surface 18 'which is abutted when the locking piece 14 is rotated by 90 °. . The present invention, which is constructed as described above, can be easily replaced with a new blade when the blades are dull or broken and can not be easily lifted. Therefore, it is unnecessary to grind blunt blades with a grinding wheel or a grinder to form a blade, The time savings can be maximized and at the same time the blade can be replaced at a lower cost, enabling efficient storage of the sick.본 고안은 날 교체가 용이한 낫에 관한 것이다.구성의 특징으로는 낫 본체(1)를 하우징(1a)과 일회용 날(1b)로 분리 구성하는데, 상기 하우징(1a)은 철판을 절첩 성형하여 상하부 지지판(11)(11')과 삽입홈(12)을 형성하되, 하부 지지판(11')의 삽입홈(12) 후미에 일회용 날(1b)이 뒤로 밀리지 않도록 걸림턱(13)을 형성하고, 상기 걸림턱(13)의 전방 양측에 잠금편(14)과 더불어 상기 잠금편(14)이 끼워지거나 빠지도록 함에 따라 상하부 지지판(11)(11')이 벌어지거나 오므러들도록 유도하는 요홈(15)을 형성하며, 상부지지판(11) 표면에 상기 잠금편(14)을 드라이버 또는 동전 등의 공구를 이용하여 회전시켜 일회용 날(1b)을 고정시키거나 분해할
