Abstract
A drill head belonging to a technical field of a drilling tool comprises a polish rod and a screw mandrel portion which is divided into two narrow-end-up portions. The polish rod end of the drill head is provided with a positioning mechanism which is nested in the sleeve barrel outside a drill rod whose wall is provided with a locking screw passing through the sleeve barrel. Using the utility model to drill a hole, a narrow-end-up coaxial step hole can be simultaneously formed, and the screw lid can merge in the hole after screwing in. The arrangement of the positioning mechanism is convenient to adjust the depth of the drilling hole.
Description
Technical field
The utility model belongs to brill reaming tool technical field, particularly a kind of drill bit.
Background technology
Existing drill bit structurally comprises polished rod and screw mandrel two parts, and screw mandrel section external diameter unanimity during use, can only get out the hole of single diameter.After screw is screwed into, outside screw cap is exposed to, influence processed mounting article profile pattern, bring certain inconvenience to use.Also influence simultaneously the attractive in appearance of object.
The utility model content
The utility model purpose is to provide a kind of drill bit that can get out up big and down small different apertures coaxial aperture simultaneously.
For reaching above-mentioned purpose, the utility model adopts following technical scheme: a kind of drill bit, comprise polished rod and screw mandrel part, and screw mandrel is divided into the up big and down small two parts of external diameter.
The drill bit polished end is provided with detent mechanism.
Detent mechanism is to be set in the outer sleeve of drilling rod, and sleeve wall is provided with the lock-screw that passes sleeve.
In the utility model, the screw mandrel section of drill bit is designed to the up big and down small two parts of external diameter.In the use, the lower outer diameter smaller portions at first get out aperture, and along with going deep into of drill bit, top external diameter major part enlarges aperture top, thereby forms a up big and down small stepped hole.After screw was screwed into, screw cap submerged in the hole, large aperture, and processed object surfacing as before.Can regulate drilling depth by the detent mechanism of adjusting on the drilling rod.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Embodiment, as shown in Figure 1, drill bit comprises polished rod 1 and screw mandrel two parts, screw mandrel is divided into the up big and down small two parts 2,3 of external diameter, is step-like.It is lock-screw that drilling rod top polished rod 1 is provided with sleeve 4,5, and loosening screw 5 can be adjusted up and down, thereby regulates drilling depth; Tighten screw 5, screw 5 and drilling rod 1 are held out against, fixedly drilling depth.6 is graduation mark.
Claims (3)
1, a kind of drill bit comprises polished rod and screw mandrel part, it is characterized in that, screw mandrel is divided into the up big and down small two parts of external diameter.
2, drill bit as claimed in claim 1 is characterized in that, the drill bit polished end is provided with detent mechanism.
