After the turntable (16) is driven to make two vertical plates (13) move away from each other and insert the insertion rod (14) into the soil, by loosening bolts (20), the arc-shaped rod (18) body being away from of the gear (17) is pulled closer under the action of a second spring (21), so that the arc-shaped rod (18) body close to the gear (17) is closed, and the teeth (18.1) on the arc-shaped rob (18) are inserted between the teeth of the gear (17), thereby locking the gear (17) against rotation and realizing the positioning function of the insertion position of the inserting rod (14) into the soil. After the drilling operation is completed, by screwing the bolt (20), the bolt (20) is pushed against the end of the arc shaped rod (18) being far away from the gear (17). Because the nut (19) is fixedly connected to the side of the pressing block (7), the rod bodies of the two arc-shaped rods (18) close to the gear (17) are opened so that the teeth (18.1) on the arc-shaped rods (18) are separated from the teeth on the gear (17). The turntable (16) is slightly rotated and the vertical plates (13) are brought closer under the action of the pull-back force of the first spring (15), and then the two inserting rods (14) are retracted from the soil into the inner cavity of the cylindrical block (8) so as to pull the cylinder block (8) and cone block (9) out from the soil and complete the drilling operation.
