Description

Technical Field

[0001] The utility model relates to the technical field of garden greening equipment, in particular to a ditching device. Background Technique

[0002] Garden construction is also known as greening construction. Garden greening is one of the necessary constructions to increase the beauty of the city. By reclaiming land in the garden and planting green plants, the air quality in the city can be improved, the beauty of the city streets can be increased, and the city appearance can be enhanced. And planting green plants requires ditching the land in advance, so a ditching device is needed;

[0003] However, during the use of the existing ditching device, when the shovel handle is fixedly connected to the ditching blade, first, the shovel handle needs to be polished, and then the polished shovel handle is inserted into the connection groove at the connection part of the ditching blade.
