s4: the second arc-shaped block (521) is opened by pressing the clamping strip (528), so that the branches of the tree needing to be shaped are wrapped by the second arc-shaped block (521) and the first arc-shaped block (511);

s5: slightly rotating the guide device (5) to enable the semicircular block (41) to rotate in the support frame (35) so as to adjust the rotating angle of the guide device (5), and then enabling the fixed friction plate (46) to move in opposite directions by rotating the fixed button (45) so as to lock the semicircular block (41), thereby controlling the growth angle of tree branches;

s6: the trees are observed regularly, and the rotary screw (22) can be rotated by reversely rotating the rotary knob (23), so that the clamping blades (26) can be moved out of the trees, and a twisting method is completed on the trees.
