Example Embodiment
[0027]Embodiment:
[0028]1. Pre-patch before the pile work: When the depth of the digging pit is adjusted, the threaded rod 302 is rotated so that the lifting frame 309 is driven to perform lifting activities, changing the initial height of the spiral tool 316, thereby changing the depth of digging pits, completing the adjustment After the bolt 305 can be fixed to the bolt 305, the turntable 303 and the threaded rod 302 can be fixed, and then the drive motor 310 and the rotary electric machine 315 are initiated, the drive motor 310 drives the transmission gear 312 and the rotation shaft 307 to rotate, the rotation shaft 307 drives the cam 311 to rotate, the convex surface of the cam 311 When rotating to the bottom, the arcuate top block 313 is pressed downward. At this time, the support spring 318 is extruded, and when the convex surface exits the bottom, the support spring 318 can drive the curved top block 313 to rise, and rotated during this process The stroke 316 is driven to perf...
