Both ends are respectively equipped at least three through-holes three, and the fixed plate one and two both ends of fixed plate are slidably socketed respectively equipped with pressure plate one
With pressure plate two, the pressure plate one and pressure plate two are equipped with the through-hole four matched with through-hole three, set in the support plate
There is the through-hole five matched with arch springing, the through-hole five is between fixed plate one and fixed plate two, the support plate four corners
It is respectively equipped with threaded hole, the threaded hole interpolation is equipped with support column, and the upper end of support column is helicitic texture.
As improvement: connecting by the way that high-strength bolt is fixed between the through-hole one and through-hole two, through-hole three and through-hole four
It connects.
As improvement: the upper end of support column is mutually fixed by the way that locking nut is solid with support plate.
As improvement: being pyramidal structure below the support column.
Advantage is the utility model compared with prior art: support plate is equipped with guide rail one and guide rail two, and guide rail one
With on guide rail two sliding be equipped with sliding block one and sliding block two, and fixed plate both ends sliding be equipped with pressure plate, by through-hole one with
Through-hole two, through-hole three size different according to arch springing from the mutual adjusting realization of through-hole four clamp arch springing to be adjusted
Fixed, applicability is high, while increasing the area of support plate, is allowed to bigger with contact area of ground, and support is more firm；In addition it props up
The phenomenon that being equipped with support column below fagging, support plate is fixed on the ground, and arch springing generation is further prevented to move horizontally hair
It is raw.
