[0033] The fixing mechanism is arranged inside the vertical rod 8 .

[0034] After the operator inserts the cone 2 and the support pile body 1 into the soil layer, the operator can hammer the top plate 9 downward so that the top plate 9 drives the vertical rod 8 and the I-shaped rod 4 to move downward, so that the I-shaped rod 4 can drive the hinged rod 5 to move, so that the hinged rod 5 can push the insertion rod 6 to move outward under the limiting action of the limiting plate 7, so that it can be moved to the outside of the support pile body 1 and then inserted into the soil layer, thereby improving the overall stability of the support pile body 1.

[0035] The fixing mechanism includes:

[0036] A clamping block 10, which is movably sleeved inside the top of the vertical rod 8, and a pull plate 12 is fixedly connected to the top of the clamping block 10, and the top of the pull plate 12 passes through the vertical rod 8 and extends to the inside of the top plate 9 and is movably connected to the inner walls of the vertical rod 8 and the top plate 9 respectively;

[0037] Spring 11, the right end of the spring 11 is fixedly connected to the left side of the block 10, and the left end of the spring 11 is fixedly connected to the inner wall of the vertical rod 8.

[0038] When the top plate 9 and the vertical rod 8 move downward, the upper surface of the supporting pile body 1 will squeeze and push the inclined surface of the block 10, so that the block 10 moves leftward into the interior of the vertical rod 8, thereby enabling the vertical rod 8 to move downward smoothly.

[0039] The outer surface of the supporting pile body 1 is fixedly sleeved with a mounting plate 13 , and both left and right sides of the mounting plate 13 are fixedly mounted with limit frames 14 .

[0042] The anti-slip plate 16 is provided to prevent the movable rod 15 from being detached from the interior of the limiting frame 14 .

[0043] The bottom end of the movable rod 15 is fixedly connected to a bottom plate 17 , and the bottom end of the bottom plate 17 is fixedly connected to a pointed cone 18 .

[0044] By inserting the pointed cone 18 into the soil, the entire supporting pile body 1 can be reinforced.

[0049] The working principle and use process of this utility model:

[0050] First, the operator points the cone 2 downward and inserts the supporting pile body 1 and the cone 2 as a whole into the soil, and then hammers the top of the top plate 9 to make the vertical rod 8 and the I-shaped rod 4 move downward, so that the hinged rod 5 can push the insertion rod 6 to move outward under the limiting action of the limiting plate 7, so that the outer end of the insertion rod 6 moves to the outside of the supporting pile body 1 and is inserted into the soil layer, so that the supporting pile body 1 as a whole can be more solid. When the top plate 9 and the vertical rod 8 move downward, the upper surface of the supporting pile body 1 will squeeze and push the inclined surface of the block 10, so that the block 10 enters the inside of the vertical rod 8 to the left, so that the vertical rod 8 can move downward smoothly. When the block 10 enters the inside of the supporting pile body 1, the spring 11 will push the block 10 to move to the right under the action of elastic recovery, so that the block 10 can limit the vertical rod 8 and prevent the vertical rod 8 from moving upward, thereby preventing the insertion rod 6 from moving inward.

[0051] After the supporting pile body 1 is inserted into the soil layer as a whole, the operator can rotate the rotating plate 21 so that the round rod 20 drives the rotating rod 22 to rotate, so that the push-pull rod 23 can push the bottom plate 17 downward, so that the bottom plate 17 drives the movable rod 15 to move downward under the limiting action of the limiting frame 14, and then the pointed cone 18 is inserted into the soil, thereby reinforcing the supporting pile body 1 as a whole and preventing the supporting pile body 1 from shaking left and right.
