1. the device is arranged on the small excavator, so that the device has high power, flexible operation and suitability for small-area operation, and can cut shrubs with thicker diameters through the arrangement of the cutting blades; the device is arranged on the bucket rod of the mini excavator, so that the device can cut at different heights, and the device can trim crowns of landscape trees; therefore, the device has strong applicability and can be suitable for most application scenes;

2. the connection stability of the cutting blade and the output shaft of the hydraulic motor can be improved through the arrangement of the pressing plate;

3. by the arrangement of the baffle, the cutting piece can be prevented from being splashed backwards to hurt people due to the fact that the cutting piece touches rigid objects such as small stones and the like when rotating;

4. the utility model is easy to detach and replace, individual parts can be replaced individually when damaged, the maintenance is convenient, and the maintenance cost is low;

5. the strength and rigidity of the frame can be enhanced by arranging the main body reinforcing ribs, so that the material consumption is saved, the weight is reduced, and the cost is reduced; the distortion of the frame caused by uneven stress of the frame due to the difference of wall thickness can be overcome;

6. through the setting of the poking piece, the cut shrubs can be poked to one side, and the sight of a driver is not influenced when the higher shrubs are cut; simultaneously, as the plectrum is connected with the frame through the revolute pair, when the device moves to one side, the cut shrubs can push the plectrum to move to the other side, and vice versa, so that the normal work of the cutting sheet is not affected, and meanwhile, the movable range of the plectrum is limited due to the existence of the two main body reinforcing ribs, so that the plectrum can normally scratch the cut shrubs to one side; the driving device can be avoided from working normally by the setting of the avoidance groove;

7. through the setting of gasket, can prevent plectrum and main part strengthening rib direct contact to prevent plectrum or main part strengthening rib by the crush injury or warp and warp, thereby extension plectrum and main part strengthening rib's life has improved the economic nature of device.
