The invention relates to a convenient ground earth
drill with a rotation speed regulating function. The convenient ground earth
drill comprises a main body and a
drill bit, and further comprises a speed regulating mechanism and a dismounting mechanism, wherein the dismounting mechanism comprises a
drive shaft, a first connecting disc, a second connecting disc, a first sleeve, a second spring, twofirst bearings and at least two connecting assemblies; the speed regulating mechanism comprises a transmission block, a friction disc, a motor and two movable assemblies; each connecting
assembly comprises a through hole, a lead screw, a second bearing and a fourth sleeve; and each moving
assembly comprises a third sleeve, a
gas cylinder, a first slide rod and two resisting units; each resisting unit comprises a second slide rod, a second sleeve and a first spring. In the convenient ground earth drill with the rotation speed regulating function disclosed by the invention, the rotation speed ofthe
drill bit can be regulated through the regulating mechanism, so that practicability of the earth drill is improved; and the dismounting mechanism improves
drill bit replacement convenience, and improves convenience of earth drill use.
