[0056] Referring to Figure 1 , Figure 2 and Figure 3 , it can be understood that in order to simplify the adjustment difficulty of the limiting space 230, the directional herbicide spraying device further comprises a supporting seat 430 connected with the frame body 100, the supporting seat 430 is connected with the side of the frame body 100, the supporting seat 430 is provided with left and right communication screw holes 431, the positioning member 410 is provided with a threaded section, the upper end of the supporting seat 430 abuts against the surrounding frame 210, the threaded section is threadedly connected with the screw holes 431 and can enter and exit the clamping rings 420, and the positioning member 410 can be arranged in the supporting seat 430 in the left and right directions.

[0057] Referring to Figure 1 , Figure 2 and Figure 3As shown, the upper end of the supporting seat 430 abuts against the surrounding frame 210, so that when the positioning member 410 exits the clasp ring 420, the surrounding frame 210 is maintained at the original height position under the support of the supporting seat 430, without the need for the user to frequently adjust the height position of the surrounding frame 210 or to continuously support the surrounding frame 210. The supporting seat 430 is provided with a threaded hole 431, which is arranged in left-right communication, and the positioning member 410 is provided with a threaded segment, which is threadedly connected with the threaded hole 431 and can enter and exit the clasp ring 420.
