The invention provides a long and short spiral anchor, and relates to the technical field of spiral anchors. The long and short spiral anchor comprises a first anchor rod body, a drill bit part, firstspiral blades, a second anchor rod body, second spiral blades, a first through hole, a first screw rod, first fixing nuts and second fixing nuts, wherein the drill bit part is connected with the other end of the first anchor rod body; the three first spiral blades are arranged on the outer side of the first anchor rod body in a sleeving mode; the second anchor rod body is arranged on the outer side, deviating from one end of the drill bit part, of the first anchor rod body in a winding mode; at least two second spiral blades are arranged on the outer side of the second anchor rod body in a sleeving mode; the first through hole sequentially penetrates through the first anchor rod body and the second anchor rod body in the radial direction of the first anchor rod body and the second anchorrod body; the first screw rod sequentially penetrates through the first anchor rod body and the second anchor rod body in the radial direction of the first anchor rod body and the second anchor rod body; the two first fixing nuts are arranged at the two ends of the first screw rod in a sleeving mode; and the two second fixing nuts are arranged on the outer side of the first screw rod in a sleevingmode.
Description
technical field [0001] The invention relates to the technical field of helical anchors, in particular to a long and short helical anchor. Background technique [0002] At present, in the related art, when the existing anchor rod is drilling a hole, due to the centrifugal force generated when the anchor rod rotates, there will be a gap between the hole drilled by the anchor rod and the anchor rod, thereby reducing the side of the anchor rod. The tension reduces the drilling accuracy of the bolt. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art. [0004] For this reason, the present invention proposes a kind of long and short helical anchor. [0005] In view of this, the present invention provides a long and short helical anchor, the long and short helical anchor is connected with the driving mechanism, so that the driving mechanism provides power for the long and short he...
