The present invention relates to a prefabricated frame capable of automatically locking a neck of a cow in a cowshed. According to the present invention, an upper bar and a lower bar are additionally joined to an upper horizontal bar and a lower horizontal bar, which are installed on an upper side and a lower side of a fixation frame. An upper mounted piece and a lower mounted piece are fixated by a plurality of bolts penetrating the upper mounting piece and the lower mounting piece. The distance between the upper horizontal bar and the lower horizontal bar of the frame is adjusted based on the size of a neck of a cow and the prefabricated frame automatically locks the neck of the cow when feed is provided to the cow. Therefore, the cow cannot place its head in another stall of another cow. The fixated frame can be easily joined with or detached from the upper horizontal bar and the lower horizontal bar and thus, the prefabricated frame capable of automatically locking a neck of a cow in a cowshed can be easily moved and stored.COPYRIGHT KIPO 2014본 발명은 고정틀의 상하부에 설치된 상,하부안착구에 결합되는 상,하부가로대에 상,하부바를 더 결합하여 상,하부안착구 및 상,하부에 다수개의 볼트가 관통되어 고정되도록 구성되어 소의 목굵기에 따라 고정틀의 상,하부가로대에서 간격을 적절하게 조정하고, 사료 급식시 소의 목부분이 자동으로 잠그어지도록 하여 다른 소의 사료칸에 침범하지 못하도록 하며, 고정틀을 상,하부가로대에 손쉽게 조립하거나, 분리하도록 하여 우사자동목걸이틀의 이동 및 보관을 용이하도록 한 조립식 우사자동목걸이틀에 관한 것이다.
