For example, thereafter, the excavation method further includes the steps of:
In step S104, the first rotating shaft 281 pushes the rectangular block body 221 to move, so that the arc-shaped body of the rectangular block body 221 moves toward the blocking frame 38, and simultaneously drives the pushing rod 223 to push the corresponding abutting plate 41, so that the rotating abutting frame 40 rotates to drive the linkage rod 29 to move away from the power arm 11, so as to force the two arc-shaped clamping strips 235 to generate flexible warpage to open the arc-shaped splitting grooves 231, the rotating motor 24 drives the two pressing strips 15 to respectively rotate into the two arc-shaped splitting grooves 231, and the two pressing blades 23 and the two pressing strips 15 are used to press and hold the stone together.
