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.
Referring to Fig.1-3, a kind of drilling project new drill, including sleeve 1, fixed station 5 and gear wheel 7, the inside of sleeve 1
Sliding sleeve is connected to steel column 3, and the outside of steel column 3 angularly welds in horizontal plane that there are four spacing block sets around the axis perpendicular of steel column 3
4, and four spacing block sets 4 correspond with four limiting slots 11 being angularly provided with vertically on 1 inner surface wall of sleeve block respectively
It connects, the top of steel column 3 passes through the top inner surface wall elastic connection of buffer spring 2 and sleeve 1, the bottom of steel column 3 and positioned at sleeve 1
Outside be welded with fixed station 5, high-pressure nozzle 6, the bottom isogonism of fixed station 5 are provided at the inner hub location of fixed station 5
