After adjusting to a suitable height, the knob 231 is rotated again to make the screw rod 232 screw into a second positioning hole 250. The distance between each second positioning hole 250 is 1 cm.

[0033] The working principle of the municipal greening shrub pruning device is as follows: when it is necessary to prune the roadside shrubs and green belts, the electric moving wheel 110 is used to move the mounting support plate 120 to the top of the shrubs, and then the driving member 150 is started, so that the first pruning knife 130 prunes the top of the shrubs when the entire device moves automatically, and then the driving member 150 drives the second pruning knife 140 to move left and right. With the cooperation of the second pruning knife 140 and the first pruning knife 130, the electric moving wheel 110 prunes while moving, and the staff pays attention to prevent the entire device from going astray. Through the cooperation of the electric moving wheel 110 and the mounting support plate 120, the hands of the staff can be freed, and the staff does not need to hold the shrubs for a long time, which can reduce the labor intensity of the staff and reduce pruning fatigue. Through the cooperation of the first pruning knife 130 and the second pruning knife 140, the pruning of the shrubs is faster and the pruning effect is better, thereby improving the aesthetics of the pruning of the shrubs. The height of the pruning assembly 10 can be adjusted by the lifting assembly 20, so that it can adapt to the pruning of shrubs of various heights, increase the practicality of the device, and can also adjust the length required for pruning according to actual needs.
