Put.
The utility model is further arranged to：The pole departs from the spacing of the anchor pole provided with the pole is limited
Ring.
By using above-mentioned technical proposal, pole can be limited in anchor pole, it is to avoid pole departs from anchor pole.
The utility model is further arranged to：The outer end of the pole is tapered to be set.
By using above-mentioned technical proposal, pole and the contact area of extraneous soil layer can be reduced, preferably pole is inserted
In extraneous soil layer.
The utility model is further arranged to：The pole is provided with sliding block, and the anchor pole is provided with slide rail, the sliding block
It is slidably connected with the slide rail.
By using above-mentioned technical proposal, pole can be avoided to be rotated during sliding outward, the end of push rod can be made
Preferably contacted between the end obliquely set with pole.
The utility model is further arranged to：The end of the anchor pole is tapered to be set.
By using above-mentioned technical proposal, can reduce anchor pole into during foundation ditch and foundation ditch contact area, using identical
In the case of the thrust of size, contact area is smaller, and the pressure that anchor pole applies to foundation ditch is bigger, and anchor pole is inserted into foundation ditch more just
Profit.
In summary, the utility model can increase the contact area of anchor pole and soil layer by setting pole, make the position of anchor pole
Put more stable, more preferable supporting effect is reached to foundation ditch.
