When it needs to be replaced, , twisting the support ring 21 drives the inclined push rod 22 to rotate, and then the inclined push rod 22 pushes the trapezoidal rod 24 to deflect, and the trapezoidal rod 24 compresses the spring 42 through the triangular head 43, and the trapezoidal rod 24 is separated from the inner cavity of the groove under the special shape of the surface of the triangular head 43, thereby separating the connecting ring 41 and the fixed head 1, and separating the drip irrigation head 3 from the inner cavity of the fixed head 1, which can facilitate the replacement of the drip irrigation head 3, so as to avoid the drying up of the soil near some crops due to the blockage of the drip irrigation head 3.

[0028] To sum up: the agricultural drip irrigation head that is easy to replace is connected through the connecting structure 2 on the surface of the fixed head 1 and the limiting structure 4 on the top of the drip irrigation head 3, so that the connection and replacement between the drip irrigation head 3 and the fixed head 1 can be faster, thereby facilitating the replacement of the drip irrigation head 3 to avoid the drying up of the soil near some crops due to the blockage of the drip irrigation head 3.
