[0038] The setting of the limit block 202a is used to apply a thrust to the baffle 202b, thereby driving the baffle 202b to move, thereby driving the limit block 202a to move, so as to facilitate the limit block 202a to automatically insert into the limit groove Q to limit the fixed plate 101.

[0039] Specifically, the limiting member 202 also includes a movable rod 202d, a top block 202e, a push block 202f, a first positioning ring 202g and a second spring 202h.

[0043] During use, when exploration and drilling are required, the device is first pushed to the position where drilling is required, and then the handles 201e at the four corners are rotated respectively, so that the handles 201e drive the threaded rod 201d to rotate, and then drive the movable column 201a to move, thereby driving the foot 201b to contact the ground, so as to level the base 108, and then turn on the motor 102 to drive the drill bit 103 to rotate, and then the user holds the handle 105 and presses the button 202i, so that the button 202i drives the extrusion block 202j to move, and then the extrusion block 202j squeezes the push block 202f. When the push block 202f is squeezed, it will move, and then drive the movable rod 202d to move, thereby driving the top block 202e to move. When the top block 202e moves, the limit block 202a in the limit slot Q will be pushed out of the limit slot Q, thereby releasing the limit on the fixed plate 101, and finally the staff slowly lowers the drill bit 103 to drill.
