Contact-impact influence the first clamp assembly 4 normal clamping.It can also be after bamboo chip be fully inserted by the second clamp assembly 5
Play the role of alignment to the installation site of bamboo chip, bamboo chip and support base 3 is made be in parastate, improves bamboo chip when drilling
Hole position precision.
After bamboo chip stretches to baffle 303, worker adjusts the position of support base 3 manually, and the position hole to be drilled of bamboo chip is made to be placed on
The underface of screw tap 22, when bamboo chip hole to be drilled is closely located to screw tap 22, worker can under the action of displacement counting device 24
Accurately to adjust the shift length of support base 3 by rotating handwheel 29, support base 3 is when moving through rack 25, rotate gear 26
The shift length of support base 3 can be included so that worker is passed through rotation on counter 31 by the cooperation with counting gear 30
Handwheel 29 and counter 31, which realize the drilling hole position of bamboo chip, to be accurately positioned, and the borehole accuracy and brill to bamboo chip are further improved
Hole efficiency.
Bamboo chip in place after, open screw tap 22 and through lifting handle 20 adjust screw tap 22 position, to complete to bamboo chip
Boring work；For screw tap 22 in drilling, the first clamp assembly 4 and the second clamp assembly 5 can prevent bamboo chip stress from deviating or sliding
It opens, makes the present invention that there is good borehole accuracy；It can be made below the middle part of bamboo chip by the cooperation of fixed angle steel and connecting plate
There are spaces to further improve the borehole stability of the present invention to avoid screw tap 22 from colliding support base 3 after the completion of drilling
Property.After the completion of primary drilling, worker makes screw tap 22 be detached from bamboo cane through lifting handle 20, and moves bamboo chip under through support base 3
One position to be drilled makes the present invention have good drilling efficiency；The cooperation of mountain type track 2 and idler wheel 302 can also make support base 3
It moves along a straight line, to improve hole position precision of the bamboo chip in drilling.After the completion of drilling, support base 3 need to be only moved back to by worker
It is in situ, then bamboo chip is directly extracted out from 3 end of support base, it just can complete the dismantlement work to bamboo chip；Bamboo chip extracts 8 He of rear plate out
Homing under the action of torsional spring 9 and Flat wire spring 12 respectively of pivoted arm 14, facilitates disassembly and installation work of the worker to bamboo chip.
