The outer wall of head is arranged with embedded drill bit through offering multiple fixed apertures in the intrusion slot that opens up of the bottom of the first drill bit,
The inner wall both sides of the intrusion slot are symmetrically fixed with limiting ball.
As further describing for above-mentioned technical proposal：
The outer wall of the embedded drill bit offers the fixation aperture equal with the first drill bit outer wall quantity.
As further describing for above-mentioned technical proposal：
The outer diameter of the internal diameter of described two sets of holes and two socket screw rods is equal.
As further describing for above-mentioned technical proposal：
The inside both sides of the nested troughs are symmetrically fixed with two Elastic buckles, and between the second drill bit and the first drill bit
Connection mode is spiral nested encryptions.
As further describing for above-mentioned technical proposal：
The outer diameter of the connecting stud is equal to the internal diameter of the top notch of connection rotation set, and connect the bottom plate rabbet of rotation set
Internal diameter is equal to the outer diameter of the second drill bit.
As further describing for above-mentioned technical proposal：
The outer diameter of the embedded drill bit is equal to the internal diameter of intrusion slot.
In the utility model, the drilling machine Multifunctional drill, first, the Multifunctional drill are bored by the first drill bit, second
Three drill bit compositions of head and embedded drill bit, in this way when actual use, can select to bore using which as needed
Head drills, secondly as the second drill bit can be directly mounted on drilling machine by connecting stud and connection rotation set, and the
The bottom of two drill bits is provided with socket screw rod again, so that when the second bit bore is used, stress point can be more single,
Stress is larger, and drilling is easier, finally, due to be embedding by spiral between the first drill bit, the second drill bit and embedded drill bit
Set mode is attached, and in this way when the Multifunctional drill is dismounted, also more convenient, the practicality is stronger.

Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.
With reference to Fig. 1-3, a kind of drilling machine Multifunctional drill, including the first drill bit 4, the top of the first drill bit 4 offers
Nested troughs 5, and the internal sleeve of nested troughs 5 is equipped with the second drill bit 3, the top of the second drill bit 3 is socketed with connection by connecting rotation set 2
Stud 1, the inside bottom horizontal central line both sides of nested troughs 5 symmetrically offer sets of holes 11, and two 11 and second drill bit of sets of holes, 3 bottoms
Fixed two sockets, the 6 spiral nested encryptions of screw rod in portion, the outer wall of the first drill bit 4, which runs through, offers multiple fixed apertures 7, and the
