In this way, it can ensure that the direction and angle of the drilling meet the design requirements and improve the accuracy and precision of the drilling. Then, the electric telescopic rod 6 is started to move to drive the contact plate 4 to contact the wall of the drilling hole, thereby increasing the stability during drilling.
