[0013] As a further solution of the present utility model: a fixed seat is installed below the mounting plate, and a driving motor is fixed inside the fixed seat.

[0014] The beneficial effects of the present utility model are as follows: Under the action of the chute and the slider, a guiding effect can be achieved, so that the rotation of the lead screw drives the movable part connected by threads to move horizontally, thereby adjusting the drill rod. Moreover, through the guide wheels arranged on the fixing plate, a guiding and limiting effect can be achieved, thereby reducing the situation that the drill rod deviates during horizontal movement; Through the hinge plate connected inside the mounting seat, when the mounting frame rotates, the limiting plate can slide on the guide rod, thereby playing an auxiliary positioning role and reducing the situation of deviation.
