[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Embodiment 1:

[0022] according to Figure 1-4 As shown, a pruning knife for green plant maintenance comprises two handles 1, the middle and upper parts of the handles 1 are cross-rotatably mounted together, a mounting groove 2 is welded on the top of the handle 1, a threaded hole is provided on the mounting groove 2, a cutter head 3 is inserted in the mounting groove 2, an L-shaped fixing plate 4 is installed on one side of the cutter head 3, a through hole is provided at the vertical end of the L-shaped fixing plate 4, and a fixing bolt 5 passes through the threaded hole on the mounting groove 2, the through hole of the L-shaped fixing plate 4 and the cutter head 3 in sequence.

[0023] The vertical end of the L-shaped fixing plate 4 contacts the cutter head 3 , and the straight end of the L-shaped fixing plate 4 contacts the top of the mounting groove 2 .

[0024] The interior of the mounting groove 2 is trapezoidal, one side of the mounting groove 2 is an inclined surface, and the inclined surface of the mounting groove 2 matches one side of the cutter head 3 .
