Above-mentioned bihexagonal head type bolt head boring grab, wherein：Otch by semicircle face and both sides plane combination
It forms.
The utility model compared with the existing technology has clear advantage and advantageous effect.By above technical scheme it is found that
In the bihexagonal head type bolt head boring grab of the utility model, there are two the settings of pedestal upper right side picks up the ears, and briquetting is mounted on
It is rotatably attached between picking up the ears and by axis pin screw, briquetting is L shaped plate body, and axis pin screw is placed in the corner of briquetting, real
Rotation of the L-shaped briquetting along turning is showed；The lower surface of briquetting one end and the upper surface of pedestal surround adjustable 12 corner apertures of area,
12 corner apertures are composed of the half hole body on briquetting with the other half hole body on pedestal, when L-shaped briquetting is along the rotation at turning
When, drive the half hole body on briquetting to compress or unclamp；Otch is arranged in the top surface of briquetting and otch and 12 corner apertures phases
Connection can be drilled after bihexagonal head type bolt is clamped by 12 corner apertures by otch above, convenient for protecting
Demonstrate,prove bore size（L dimension）Accuracy；12 corner apertures rears are provided with the mandril that can be moved along 12 corner apertures axis directions, can
According to different L dimensions, to adjust mandril position, reach positioning purpose；The other end of briquetting, which runs through, is equipped with housing screw, and presses
The tight end of screw is in contact with the side of pedestal, convenient for by rotatably compressing the rotation of screw belt dynamic pressure block.In short, this practicality is new
Type is accurate and feasible, stabilization is practical, simple operation, high-quality durable, and the popularization of bihexagonal head type bolt head boring clamping is suitble to make
With.
