Preferably, the reaming bar is arranged between shank and drilling rod, and reaming bar grooves on two sides is in reaming bar
Line is symmetrical.
Preferably, the centre position of the shank is provided with circular hole.
Preferably, the cross sectional shape of the reaming bar, shank and drilling rod is circle, and the diameter of reaming bar is more than shank
With the diameter of drilling rod.
Preferably, the reaming bar and shank are integral type structure.
Compared with prior art, the beneficial effects of the utility model are：The equipment is set in the groove of reaming bar both sides
There is hiding reaming blade, can be worked in the presence of push rod so that device can carry out reaming after completing to drill, not only
Operating efficiency is improved, also avoids the trouble of more bit change, reduces the working strength of staff, the drilling rod of device and reaming
Connection is detachably fixed by screw between bar, is easy to user according to actual conditions more bit change, it is corresponding relative to a drilling rod
One reaming bar, the present apparatus more save material, at the same it also avoid bit wear and reaming blade remains unchanged available contradiction, and
The present apparatus can also change the diameter of reaming by changing the diameter of push rod in circular hole, can meet user's difference counter bore diameter
It is required that the present apparatus is reasonable in design, overall structure is simple, uniqueness drilling and the structure of reaming integral type, even more facilitates user's
Use.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Refer to Fig. 1 and Fig. 2, a kind of embodiment provided by the utility model：Drill hole of drilling machine reaming bit, including keyway 1,
Shank 2, positioning hole 3, reaming bar 4, screw 5, drilling rod 6, drilling blade 7, cutting head 8, reaming blade 9, groove 10, push rod 11,
Banking pin 12 and circular hole 13, the outer surface of shank 2 is provided with keyway 1, and is provided with positioning hole 3 on the reaming bar 4 of the lower end of shank 2
With groove 10, banking pin 12 is provided with the positioning hole 3 of reaming bar 4, and the reaming blade 9 in groove 10 passes through pin and reaming
The body of rod inside bar 4 is flexibly connected, and push rod 11 is provided with the circular hole 13 among reaming bar 4, and drilling rod 6 passes through spiral shell with reaming bar 4
Nail 5 is detachably fixed connection, and the outer surface of drilling rod 6 is provided with drilling blade 7, and the end of drilling rod 6 is provided with cutting head 8, expands
Vent stem 4 is arranged between shank 2 and drilling rod 6, and the grooves on two sides 10 of reaming bar 4 is symmetrical on the center line of reaming bar 4, shank 2
