When the pushing plate 75 is separated from the wedge-shaped supporting frame 72, the stretched supporting spring 73 is reset to drive the wedge-shaped supporting frame 72 to move and reset in the direction close to the rack rod 66, the rack plate 65 moves upwards to drive the pushing rod 92 to move upwards, the pushing rod 92 pushes the reset rod 91 and the second lower pressing rod 88 to move upwards, the second lower pressing rod 88 is separated from the hole limiting plate 84, the stretched first stretching spring 85 is reset to drive the hole limiting plate 84 to move in the direction away from the guide plate 31, the second lower pressing rod 88 can push the wedge-shaped supporting frame 72 to move in the direction away from the rack rod 66, the wedge-shaped supporting frame 72 moves and resets in the direction close to the rack rod 66, and the wedge-shaped supporting frame 72 blocks the second lower pressing rod 88. When the lubricating oil in the oil reservoir 81 is used up, the worker injects the lubricating oil into the oil reservoir 81 through the liquid injection pipe 82. When the equipment is not needed, the operator manually turns off the drilling motor 33, which stops the equipment.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
