The utility model solves the technical scheme that its technical problem used：A kind of Split type drill, including drillstock, brill
Body and drill bit, chisel edge be arranged with two be used for cut cutting blade, bore body provided with cutting blade rotational trajectory, two
Chip area is formed between the rotational trajectory of cutting blade, it is characterised in that：The brill body and drill bit clamping,
The bit upper end, which has in a tongue, the tongue and drill bit, is formed with cavity, tongue side wall pair
Claim in the kidney ellipsoid elongated hole for being formed with two vertical directions, the elongated hole provided with the locating rod for protruding from tongue side wall, the sky
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 blocking
Connect the neck of locating rod.
Specifically, the neck includes a transverse part and an inclined portion, transverse part and inclined portion formation " factory " font neck, the neck
Transverse part have one be used for block set locating rod, limit bit groove.
For the ease of drill bit is disassembled, the locating rod two ends have removal hole.
Prevent locating rod along perpendicular to drill bit to ensure to be fixed with the stability during drill bit use, the locating rod
The spacer of axis direction motion.
Specifically, the drillstock is externally provided with frosted layer.
The beneficial effects of the utility model are：A kind of Split type drill that the utility model is provided, will by extension spring
Locating rod is fastened in neck, it is entirely avoided connected by way of engagement, it is necessary to during more bit change, it is only necessary to adjustment positioning
Bar, in the absence of stuck phenomenon；Locating rod two ends have removal hole, easily facilitate the dismounting and replacing of drill bit, locating rod
On be fixed with and prevent locating rod along the spacer that is moved perpendicular to drill axis direction, it is ensured that drill bit will not in the course of the work
Come off.
