And contradicted with the drill bit inserted in drill bit bore, the external circumferential of the track plate offers multiple through-holes, is equipped with and leads in through-hole
To bar, cooperation sliding is equipped with sliding sleeve on guide rod, and the downside of sliding sleeve is detachably equipped with cutting head, and the is equipped on the upside of sliding sleeve
Two hinged-supports, telescopic rod is hingedly equipped on the second hinged-support, and telescopic rod is equipped with fixed knob, the upper end of the telescopic rod and rotation
The the first hinged-support articulated connection being arranged on the outside of shaft.
As a further solution of the present invention: the track plate structure in the form of annular discs.
As a further solution of the present invention: the boss structure cylindrical.
As a further solution of the present invention: the through-hole is rectangular opening, and through-hole is circumferentially uniformly provided with four.
As a further solution of the present invention: the central axes that the axially-extending line of the guide rod passes through track plate.
Compared with prior art, the utility model has the beneficial effects that the stable adjustable metal hole making drill, use are replaceable
Drill bit, avoid when drill bit damages, the phenomenon that entire hole making drill is not available, while can aperture is not as needed
Same material, carrys out the type of more bit change, realizes multi-use；It, equally can be in cutting head using replaceable cutting head
When damaging, timely replace；The length of telescopic rod can be adjusted, and then adjust the position of sliding sleeve according to the size of aperture, if
Surely the installation site of cutting head is needed, it is convenient timely to be adjusted according to field condition, use enhanced convenience multiplicity
Change.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the overlooking structure diagram of the utility model middle orbit disc portion.
In figure: 1- rotary shaft, the first hinged-support of 2-, 3- telescopic rod, 4- fixed knob, 5- screw, the second hinged-support of 6-, 7-
Track plate, 8- sliding sleeve, 9- cutting head, 10- guide rod, 11- through-hole, 12- drill bit, 13- drill bit bore, 14- boss, 15- threaded hole.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Please refer to Fig. 1~2, in the utility model embodiment, a kind of stable adjustable metal hole making drill, including rotary shaft 1, rail
Road disk 7, cutting head 9 and drill bit 12, the track plate 7 structure in the form of annular discs, the top center of track plate 7 are formed with boss 14,
The structure cylindrical of boss 14, the lower end of rotary shaft 1 are fixedly connected with boss 14, are offered among the bottom of the track plate 7
The drill bit bore 13 in boss 14 is extended to, drill bit 12 is fitted in drill bit bore 13, threaded hole 15, screw are also provided on boss 14
5 are coupled and contradict on threaded hole 15 and with the drill bit 12 that inserts in drill bit bore 13, can be consolidated to drill bit 12 by screw 5
It is fixed, and the replacement of drill bit 12 is facilitated to safeguard.
The external circumferential of the track plate 7 offers multiple through-holes 11, and the through-hole 11 is rectangular opening, and through-hole 11 is circumferential
