As the first preferred version of the present utility model, crust of the device inner hollow, outside in cylindrical shape, cross section is circular, with pressure push-rod contact portion smooth surface at crust of the device upper end open, enabling pressure push-rod to move along crust of the device internal diameter direction, crust of the device lower end has four slotted eyes all around, makes supporting steel block can launch in crust of the device and close.
As the second preferred version of the present utility model, pressure push-rod top semicircular in shape, middle part is cylinder, and bottom is truncated cone-shaped, inner hollow, and pressure push-rod cylindrical cross-section internal diameter is more than the straight warp of anchor bar body, it is possible to make pressure push-rod move up and down along anchor bar body.
As the third preferred version of the present utility model, elastic parts is installed on anchor bar body, and is resisted against between top shoe and sliding block, and the elastic force of elastic parts can drive top shoe to move, thus drives supporting steel block from the closed to the open.
As the 4th kind of preferred version of the present utility model, one cannelure of each formation on top shoe and the two ends relative with sliding block, the part of elastic parts houses in cannelure.
The beneficial effects of the utility model are: a kind of internal stay diffusion formula anchor pole head is by pressurizeing to pressure push-rod, pressure push-rod pushes down on top shoe, and then by pull bar, supporting steel block is supported on the wall of a borehole, make supporting steel block that drill hole inner wall to be formed squeezing action, increase anchor pole end anchorage intensity.
