The fastening bolt of drilling rod axle；The drill bit internal is machined with storage chamber, be provided with the lateral wall of the drill bit it is multiple with it is described
The permeability hole of storage chamber connection, and the main shaft is provided with the runner connected along its length and with the storage chamber, it is described
Drill bit both sides are equipped with the strip groove along the crown height direction, and the bottom of the strip groove is provided with multiple screw threads
Hole, is provided with mounting blocks in the strip groove, and level is connected with proof rubber plate on the mounting blocks, and the two of the mounting blocks
End is equipped with mounting hole, and the bolt with the corresponding threaded holes is provided with the mounting hole.
Further, the drill bit is in bullet shaped.
Further, the axis of the fastening bolt is arranged on same straight line.
Further, also it is coated with wearing layer on the lateral wall of the drill bit.
Compared with prior art, the beneficial effects of the invention are as follows：Main shaft and drilling rod axle in the present invention use threaded connection,
Simultaneously and main shaft and drilling rod axle are fixed together with fastening bolt, can so adjust the length of drilling rod；The present invention is in drill bit
The upper permeability hole that storage chamber is set and communicated therewith, runner is set in the inside of main shaft, is easy to water to flow to the position of drill bit to it
Cooled, therefore, the practicality of the device is extremely strong, is especially suitable for commercially promoting.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
Fig. 1-3 are referred to, the present invention provides a kind of technical scheme：A kind of sectional rod, including main shaft 1, be fixedly connected on
The drill bit 2 of the one end of main shaft 1 and the drilling rod axle 3 being set on main shaft 1, external screw thread 4, the drilling rod are provided with the main shaft 1
The inside of axle 3 is provided with the strip through-hole 5 along the length direction of drilling rod axle 3, and the drilling rod axle of the position of the strip through-hole 5
The internal thread 6 to match with the external screw thread 4 is provided with 3 inwalls, is used on the lateral wall of the drilling rod axle 3 at least provided with a pair
In the fastening bolt 7 of fixed main shaft 1 and drilling rod axle 3；Storage chamber 8, the lateral wall of the drill bit 2 are machined with inside the drill bit 2
On be provided with multiple permeability holes 9 connected with the storage chamber 8, and the main shaft 1 be provided with along its length and with it is described
The runner 10 that storage chamber 8 connects, the both sides of drill bit 2 are equipped with the strip groove 11 along the short transverse of drill bit 2, and described
The bottom of strip groove 11 is provided with multiple screwed holes 12, and mounting blocks 13, and the mounting blocks are provided with the strip groove 11
