[0030] Wherein, clamping frame b is the open downward character-shaped.

[0031] Wherein, drilling equipment 1 further includes suction structure k, and suction structure k is used for the suction assembly of drilling pad plate h on top pressing plate g.

[0032] The adsorption structure k comprises a movable joint k1, a suction cup k2, a connecting pipe k3, an outer sleeve k4, an inner pipe k5, a piston groove k6, a connecting rod k7 and a piston k8. The suction cup k2 is embedded on the side of the top pressing plate g adjacent to the drilling pad h. The side of the suction cup k2 away from the drilling pad h penetrates the top pressing plate g through the connecting pipe k3 and is connected with the inner pipe k5.
