When digging pits at fixed points, first the front disc support feet and the rear disc support feet are attached to the ground, the digging machine is placed vertically on the ground, and the pointed feet of the front disc support feet are inserted into the soil to fix the digging machine. Then by manually holding the second handle to realize the movement of the slider along the direction of the guide rail, and then realize the overall up and down movement of the gasoline engine fixing bracket, the gasoline engine, and the drill bit. During the pit digging operation, the gasoline engine is first started, and the drill bit with spiral blades of the pit digger can be controlled to rotate and dig the pit through the manual throttle. The whole work project is convenient and easy.

Beneficial effects of the utility model:

The utility model has the advantages of compact structure, light and handy movement, convenient operation, manual controllable feed movement and return movement, and can be flexibly adjusted when encountering obstacles or obstacles during operation, so as to realize correction and greatly improve operation efficiency; , The feed speed of the drill bit is adjustable, and the digging efficiency is high.
