The threaded portion and the helical blade 10 are located at two ends of the spline portion 801, and here, the spline portion 801 is located between the threaded portion and the helical blade 10, and it is not necessary that both the threaded portion and the helical blade 10 are adjacent to the spline portion 801; the edge of one end of the helical blade 10, which is far away from the spline part 801, is perpendicular to the center line of the transmission rod 8, so that the bottom of a hole dug by the helical blade 10 is always a plane; the outer diameter of the spiral blade 10 is equal to the inner diameter of the repairing cylinder 5, and the size of the spiral blade 10 in the length direction of the transmission rod 8 is larger than the length of the repairing cylinder 5, so that the produced soil can move upwards through the spiral blade 10 in the hole digging process; the adjusting ring 9 with screw thread portion threaded connection so can guarantee to rotate adjusting ring 9 and just can adjust the upper and lower position of adjusting ring 9, the transfer line 8 passes the splined hole, spline portion 801 with the splined hole cooperation is connected, adjusting ring 9 supports and leans on baffle 7. The position of the adjusting ring 9 on the transmission rod 8 is changed by arranging the adjusting ring 9, the adjusting ring 9 is positioned above the baffle 7, the adjusting ring 9 can form a limiting structure with the baffle 7, and when the adjusting ring 9 is attached to the baffle 7 and the repair cylinder moves to the lowest position, the maximum position of downward movement of the helical blade is formed. Therefore, for the convenience of adjustment, a scale mark can be arranged on the transmission rod 8 and used for marking the maximum downward moving position of the helical blade corresponding to the position of the adjusting ring 9; in fact, the adjusting ring 9 is provided to control the extension of the helical blades 10 downwards the length of the casing, while maintaining this extension, in order to facilitate the excavation of the earth. For example, a plane may be cut along the center line on the threaded portion of the driving lever 8, and a scale may be provided along the length direction. Of course, in order to ensure that the adjusting ring 9 is within its adjustable range, the baffle 7 should have a sufficient thickness.
The driving assembly 11 is slidably mounted on the guide plate 4, and the driving assembly 11 is connected with the transmission rod 8 to drive the transmission rod 8 to rotate.
When the device is used specifically, the substrate 1 is horizontally placed at a position to be punched, and then the bracket is installed on the substrate to enable the central line of the sliding hole 301 and the central line of the standard hole 101 to be positioned on the same straight line; then, when the adjusting ring 9 is rotated upwards to enable the lower end of the adjusting ring 9 to abut against the baffle 7, the length of the lower end of the spiral blade 10 extending out of the trimming cylinder 5 is 1-6cm, then the driving assembly 11 is started to enable the transmission rod 8 to rotate, the transmission rod 8 drives the spiral blade 10 to rotate, and the spline part 801 of the transmission rod 8 is matched and connected with the spline hole in the baffle 7, so that the trimming hole assembly also rotates along with the transmission rod 8. Then the operator pushes down to make the driving component move downwards slowly, because the lower end of the helical blade 10 extends out of the repair cylinder 5, the lower end of the helical blade 10 is firstly inserted into the standard hole 101, along with the downward movement of the driving component, the lower end of the helical blade 10 contacts with the ground to start hole digging, and the dug soil moves upwards through the upper end of the helical blade 10.

When the depth of the first round hole reaches the required depth, the driving assembly is closed, the driving assembly is moved upwards to pull the lower end of the helical blade 10 out of the hole, the adjusting ring 9 is rotated downwards again to enable the lower end of the adjusting ring 9 to abut against the baffle 7, and the lower end of the helical blade 10 is flush with the lower end of the repair cylinder 5. Then the driving assembly is restarted and moves downwards to enable the spiral blade 10 and the repairing cylinder 5 to be synchronously inserted into the hole until the spiral blade and the repairing cylinder are lowered to the required depth of the hole, so that the repairing cylinder 5 can repair the whole side wall of the hole, and simultaneously soil generated in the repairing process can be discharged through the spiral blade 10. This application does not need the manual work to dig the hole in advance, can accomplish simultaneously dig the hole and maintain to the pore wall and the hole bottom of hole, and the simple structure convenient operation of whole device.
In a preferred embodiment, the hole trimming assembly is provided with a soil discharging cylinder 12 and a guide cylinder 13 which are coaxial in sequence in a direction away from the trimming cylinder 5. The purpose of the soil discharging barrel 12 is to facilitate removal of excavated soil for easy removal and weighing. The guide cylinder 13 is used for cooperating with the slide hole 301 to realize the movement of the hole trimming component along the axial direction of the slide hole.
The diameter of the soil discharging cylinder 12 is equal to that of the guide cylinder 13 and is larger than that of the standard hole 101; the diameter of the trimming barrel 5 is smaller than the diameter of the standard hole 101, and specifically, the diameter of the trimming barrel should be slightly smaller than the diameter of the standard hole 101, for example, 1-8mm smaller than the diameter of the standard hole 101. The distance from the cutting edge of the first cutting edge 6 to the center line of the trimming barrel 5 is equal to half of the diameter of the standard hole 101. In this way, the diameter of the hole trimmed by the trimming cylinder 5 can be ensured to be the same as the diameter of the standard hole 101. Therefore, the inner wall of the soil hole can be trimmed to be closer to the standard cylindrical surface only by rotating the trimming cylinder 5 along the central line of the soil hole. The baffle 7 is arranged in the guide cylinder 13, and the baffle 7 is perpendicular to the central line of the guide cylinder 13.
A plurality of outlet holes 1201 are formed in the periphery of the soil outlet cylinder 12, and the outlet holes 1201 are uniformly distributed along the circumferential direction of the soil outlet cylinder 12. By providing the soil discharge tube 12, soil generated during hole excavation can be discharged to the base plate 1 through the outlet hole 1201 of the soil discharge tube 12. Specifically, when the spiral blade digs, the excavated soil moves upward with the rotation of the spiral blade, and is thrown off to the base plate 1 by the centrifugal force after reaching the position of the outlet hole 1201. The side plates 2 also serve to prevent soil particles from scattering in the process.
Furthermore, a limiting ring 14 is arranged on the end surface of the soil outlet cylinder 12 close to one side of the repairing cylinder 5. The inner diameter of the limiting ring 14 is not less than that of the repair cylinder 5; the outer diameter of the limiting ring 14 is equal to the diameter of the standard hole 101, and the limiting ring 14 and the soil outlet barrel 12 are coaxially arranged. The function of the stop ring 14 is mainly to form a structure which is matched with the standard hole 101, so as to prevent the first cutting edge 6 from being excessively contacted with the standard hole 101 to cause scratch or damage. It may be further preferred that the length of the first cutting edge 6 may be shortened while the length of the stop collar 14 in the axial direction is increased, e.g. the length of the first cutting edge 6 is not more than one fifth of the length of the dressing barrel 5 and the length of the stop collar 14 in the axial direction is not less than four fifths of the length of the dressing barrel 5. In this way, in the process of moving down the repair cylinder 5, the chance of contact between the first cutting edge 6 and the standard hole 101 can be reduced, thereby preventing scratches or damage between the first cutting edge 6 and the standard hole 101. And, when the hole is dug, the first blade 6 has finished trimming the upper side wall of the hole as the trimming cylinder 5 rotates and moves down.
Further, a baffle ring 15 is arranged at one end of the guide cylinder 13, which is far away from the soil outlet cylinder 12, the inner diameter of the baffle ring 15 is not smaller than that of the guide cylinder 13, and the outer diameter of the baffle ring 15 is larger than that of the sliding hole 301. The purpose of the retainer ring 15 is to limit the depth of downward movement of the assembly, i.e. when the bottom surface of the retainer ring 15 contacts the holder plate 3 or is blocked by other parts, it will not move downward.
A first slideway 302 and a second slideway 303 are arranged on the support plate 3; the first slideway 302 and the second slideway 303 are both parallel to the guide plate 4; the first slideway 302 and the second slideway 303 are both positioned between the two guide plates 4; and the first slide way 302 and the second slide way 303 are positioned at both sides of the slide hole 301.
