Connect, it is necessary to during more bit change, it is only necessary to locating rod is adjusted, in the absence of stuck phenomenon.
The technical solution adopted for the present invention to solve the technical problems is：A kind of Split type drill, including drillstock, bore body and
Drill bit, chisel edge be arranged with two for cut cutting blade, bore body and be provided with the rotational trajectory of cutting blade, two cut
Chip area is formed between the rotational trajectory of blade, it is characterised in that：It is described to bore body and drill bit clamping,
The bit upper end has a tongue, and cavity, tongue side wall pair are formed with the tongue and drill bit
Title is formed with two kidney ellipsoid elongated holes of vertical direction, and the locating rod for protruding from tongue side wall, the sky are provided with the elongated hole
There is extension spring, described extension spring one end is fixedly connected with cavity bottom, and the other end is fixedly connected with locating rod in chamber,
Locating rod is set to be maintained at the extreme position on the downside of elongated hole,
The brill body lower end is formed with the jack matched with tongue shape, and the jack sidewall symmetry is formed with for card
Connect the draw-in groove of locating rod.
Specifically, the draw-in groove includes a transverse part and an inclined portion, and transverse part and inclined portion form " factory " font draw-in groove, the draw-in groove
Transverse part have one be used for block set locating rod, limitation bit groove.
For the ease of drill bit is disassembled, the locating rod two ends have removal hole.
To ensure the stability during drill bit use, being fixed with the locating rod prevents locating rod along perpendicular to drill bit
The spacer of axis direction motion.
Specifically, the drillstock is externally provided with frosted layer.
The beneficial effects of the invention are as follows：A kind of Split type drill that the present invention is provided, by extension spring by locating rod card
It is located in draw-in groove, it is entirely avoided connected by way of engagement, it is necessary to during more bit change, it is only necessary to adjust locating rod,
In the absence of stuck phenomenon；Locating rod two ends have removal hole, easily facilitate the dismounting of drill bit and change, and are fixed with locating rod
Locating rod is prevented along the spacer moved perpendicular to drill axis direction, it is ensured that drill bit will not fall off in the course of the work.
