Working principle of the present invention is as follows: casing is mounted in the outer circle of matrix when construction, power head drives when drilling
Matrix rotation, head are contacted with stratum by stratum frictional force, and matrix rotation drives three spin-block synchronous rotaries, the triangle on head
Boss is made three spin-blocks respectively rotate by a certain angle expansion with shaft axle center by reaction force, and spin-block part realizes that reaming is broken
Function；After bore operation, power head is reversely rotated, and spin-block synchronizes automatic gathering, and drill bit is promoted out of casing and taken after gathering
Out.
The invention has the following advantages: 1, drill body is assembled by matrix, spin-block and head, any part damage
It is bad to be individually replaced, it reduces costs, extends the service life of system, save the time that renovation is repaired；2, spin-block is unfolded
Diameter increases counter bore diameter with pipe bit compared to wear-resisting ring type, and can design a variety of various sizes of spin-blocks and be replaced, often
Kind spin-block corresponds to different deployment diameters, realizes that function is adjusted in counter bore diameter；3, positive stop lug boss is set and corresponding limit is heavy
Hole, spin-block continues stress when the shaft of spin-block and circular hole being avoided abrasion deformation occur, and transmits matrix directly by rotary power
To head, to improve the service life of spin-block.
