In groove 21, the first block is located at outside drill bit 20, and the first connecting handle 22 can be movable in the first loose slot 21, and then drives each first
Block deviates the movement of the center position of drilling rod 10, so as to carry out the ream operation of anchor pole drilling；Two second are provided with first block
Loose slot 31, the second eccentric block 40 include the second block of two relative spacing arrangements, second are connected with each second block
Connecting handle 32, activity is set in two the second loose slots 31 each second connecting handle 32 respectively, and the second block is arranged in outside the first block,
Second connecting handle 32 can be movable in the second loose slot 31, and then drives each second block to deviate the center position of the first block and move
It is dynamic, anchor pole drilling engineering is further carried out ream operation.
In specific works, when drill bit 20 rotates counterclockwise, two the first blocks be moved to outwardly the periphery of drill bit 20 with
Outside, so as to increase the aperture of anchor pole drilling, two the second blocks are moved to beyond two the first block peripheries outwardly respectively, enter one
The aperture for putting forward big anchor pole drilling of step, makes it meet engineering demand；When drill bit 20 rotates clockwise, two the first blocks are inwardly
It is moved within the periphery of drill bit 20, two the second blocks are moved within two the first block peripheries outwardly respectively, so, anchor pole
After drilling engineering terminates, anchor pole boring means can be reclaimed easily.
In the present embodiment, the first loose slot 21 includes the first vat section and connects the first sulculus section of the first vat section,
First sulculus section is located at below the first vat section, and through the lower surface of drill bit 20；First connecting handle 22 include the first big head section with
And the first small head section of the first big head section is connected to, the first small head section connects the first block；First big head section is movably placed in first
In vat section, the first big head section diameter is more than the first sulculus section, and in so preventing that anchor pole from creeping into, the first block departs from drill bit
20；First small head section activity is located in the first sulculus section, in anchor pole drilling process, the first block is displaced outwardly out drill bit
20 peripheries, and then expand the aperture of anchor pole drilling engineering.
In the present embodiment, the second loose slot 31 includes the second vat section and connects the second sulculus section of the second vat section,
Second sulculus section is located at below the second vat section, and through the lower surface of the first block；Second connecting handle 32 includes second largest head section
And the second small head section of second largest head section is connected to, the first small head section connects the second block；Second largest head section is movably placed in
In two vat sections, second largest head section diameter is more than the second sulculus section, and in so preventing that anchor pole from creeping into, the second block departs from first
Block, the second small head section activity is located in the second sulculus section, in anchor pole drilling process, the second block is displaced outwardly out
One block periphery, and then further expand the aperture of anchor pole drilling engineering.
In the present embodiment, the first vat section is in triangular prism shape, and the lateral cross section of the first big head section is in triangular shape, is so set
Benefit be that triangular prism shape has larger longitudinal holding power, the ability to bear of the first vat section is favorably improved, so as to improve
The service life of part；Triangular shape has higher stability, contributes to the first big head section in moving process, and it is stable to increase it
Property, so that overall structure is more steady, while the aperture for forming reaming is more uniform, it is not influenceed the anchor force of anchor pole
And anchoring effect.
In order to increase the endurance of the second vat section, the second vat section is in triangular prism shape, and triangular prism shape has larger indulge
To holding power, the ability to bear of the second vat section is favorably improved, so as to improve the service life of part；The horizontal stroke of second largest head section
It is in triangular shape to section, triangular shape has higher stability, contributes to second largest head section in moving process, and it is stable to increase it
Property, so that overall structure is more steady, while the aperture for forming reaming is more uniform, it is not influenceed the anchor force of anchor pole
And anchoring effect.

Second eccentric block 40 is consistent with direction of first eccentric block 30 along the outside activity in the center of drill bit 20, when drilling rod 10 works clockwise
When, the second eccentric block 40 is consistent along the periphery of drill bit 20 to the direction that the center position of drill bit 20 collapses with the first eccentric block 30, so
The benefit of setting is to make the first eccentric block 30 work with the second eccentric block 40 to be independent of each other, and helps to creep into engineering in anchor pole
Terminate to make to the more convenient of the withdrawal of drill bit 20.
In the present embodiment, the diameter of the first eccentric block 30 is more than the diameter of drill bit 20, and so can achieve the effect that is, as far as possible
Increase the aperture of the reaming of the first eccentric block 30, so as to influence the aperture of the reaming of the second eccentric block 40, expand the second eccentric block 40
The aperture in hole further increases, and it is met requirement of engineering.
It is easy to reclaim in order to which anchor pole drilling engineering terminates rear instrument, the diameter of the second eccentric block 40 is slightly less than the first eccentric block
30 diameters, so, in the case where not influenceing the reaming effect of anchor pole drilling, the recovery for instrument of being more convenient for.
In the present embodiment, the block outer of the block outer of the first eccentric block 30 and the second eccentric block 40 is in arc-shaped, this
The benefit that sample is set is, in anchor pole drilling process, reduces abrasion of the soil layer to the first eccentric block 30 and the second eccentric block 40, together
When can reduce soil layer to the first eccentric block 30 and the resistance of the second eccentric block 40, improve efficiency to while, contribute to increase by zero
The service life of part.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
