Abstract

The invention discloses a digging device, and more particularly relates to a special planting digging device. The special planting digging device comprises a rotating handle, a rotating shaft, an advancing seat, a bracket, a bracket base and a chassis which are in turn connected, the lower end of the rotating shaft passes through the chassis, the lower end of the rotating shaft is also provided with a boring head, the advancing seat and the rotating shaft are in threaded connection, a fastener for fixing is arranged between the bracket and the bracket base, the fastener comprises a bolt and a fixed cap, the bolt includes a bolt head and a screw rod, the fixed cap includes a perform piece prepared from spring steel, the perform piece is provided with a through hole for the screw rod to pass through, the outer side of the through-hole is provided with a wedge-shaped side wall, the screw rod is provided with an annular groove for the wedge-shaped side wall to penetrate in, the annular groove is provided with an annular edge for matching with the wedge surface of the wedge-shaped side wall, and the bracket and the bracket base are sandwiched between the preform piece and the bolt head. The special planting digging device overcomes the technical disadvantage that the bracket is easy to fall off from the bracket base in the prior art, and the special planting digging device capable of preventing the bracket from falling off from the bracket base is provided.

Description

technical field [0001] The invention relates to a pit digger, in particular to a special pit digger for planting. Background technique [0002] People need to dig holes on the ground during agricultural planting, forestry planting or greening planting. It is common to use hoes or shovel tools for digging operations. Standards affect the quality of planting. [0003] In order to solve the above-mentioned technical problems, Chinese patent CN203675575U provides a special pit digger for planting. There are propelling threads on the hollow inner wall of the seat, and the propulsion seat is connected to the chassis through a bracket; the rotating shaft is a round rod shaft structure, the spiral rib is arranged on the lower shaft body of the rotating shaft, and the tunneling head is arranged at the lower end of the rotating shaft. There are external threads on the shaft body above the ribs, and the external threads on the shaft body are rotated and pushed together with the advan...
