Slide blocks 903 are fixed on both sides of the retractable rod 904, and a turntable 11 is fixedly sleeved on the outer side of the rotating shaft 16 away from the second telescopic rod 904. The inner ring of the turntable 11 is provided with limiting holes 17.

A sliding groove is opened on the inner side of the arc plate 902 close to the slider 903, and the slider 903 and the sliding groove of the arc plate 902 are slidably connected.

[0025] During specific implementation, since the ground to be drilled may not be very flat, the road construction drilling device is easily placed unsteadily, which may cause the drilled hole to deviate and affect the drilling quality.
