The object of the invention and solves its technical problem underlying using following technical scheme to realize：
The bihexagonal head type bolt head boring grab of the present invention, including base, briquetting, wherein：Base upper right side is provided with two
It is individual to pick up the ears, briquetting is arranged on pick up the ears between and be rotatably attached by bearing pin screw, the lower surface of briquetting one end and base
Upper surface surrounds adjustable 12 corner apertures of area, and otch is arranged on the top surface of briquetting and otch is connected with 12 corner apertures,
12 chamfered groove rears are provided with the push rod that can be moved along 12 chamfered groove axis directions；The other end of briquetting runs through equipped with compression spiral shell
Nail, and the end of housing screw is in contact with the side of base.
Above-mentioned bihexagonal head type bolt head boring grab, wherein：Briquetting is L shaped plate body, and bearing pin screw is placed in briquetting
Corner, 12 corner apertures and housing screw are respectively arranged on the biside plate of L shaped plate body.
Above-mentioned bihexagonal head type bolt head boring grab, wherein：12 corner apertures are by the half hole body and base on briquetting
On second half hole body combine.
Above-mentioned bihexagonal head type bolt head boring grab, wherein：Otch by semicircle face and both sides plane combination
Form.
The present invention compared with the existing technology has clear advantage and beneficial effect.From above technical scheme, this hair
In bright bihexagonal head type bolt head boring grab, base upper right side is provided with two and picked up the ears, and briquetting is between picking up the ears
And be rotatably attached by bearing pin screw, briquetting is L shaped plate body, and bearing pin screw is placed in the corner of briquetting, realizes L-shaped pressure
Rotation of the block along turning；The lower surface of briquetting one end and the upper surface of base surround adjustable 12 corner apertures of area, 12 corner apertures
Combined by the half hole body on briquetting and second half hole body on base, when rotation of the L-shaped briquetting along turning, band dynamic pressure
Half hole body on block is compressed or unclamped；Otch is arranged on the top surface of briquetting and otch is connected with 12 corner apertures, when ten
It after two angle head type bolts are clamped by 12 corner apertures, can be drilled by otch above, be easy to ensure drilling chi
It is very little（L dimension）Accuracy；12 chamfered groove rears are provided with the push rod that can be moved along 12 chamfered groove axis directions, can be according to not
Same L dimension, regulation push rod position, reaches positioning purpose；The other end of briquetting, which runs through, is equipped with housing screw, and housing screw
End is in contact with the side of base, is easy to rotate by rotatably compressing screw belt dynamic pressure block.In a word, the present invention it is accurate and feasible,
Stable practicality, simple operation, high-quality durable, suitable bihexagonal head type bolt head boring clamping is promoted the use of.
