[0020] Specifically, the support portion includes a bottom plate 3, a baffle plate 4 is provided on the top of the bottom plate 3, and a connecting groove 401 for concrete to flow into the hole is provided on the front of the baffle plate 4;
[0021] It should be noted that the bottom plate 3 and the extension rod 2 are fixed by welding, the top of the bottom plate 3 is an inclined surface, which is convenient for the flow of concrete, the outlet of the connecting groove 401 is close to the side of the reserved hole, the baffle plate 4 and the bottom plate 3 are fixed by welding, and the side of the baffle plate 4 away from the connecting groove 401 is a smooth plane, which is convenient for blocking the side of the reserved hole, and the height of the baffle plate 4 is greater than the diameter of the reserved hole;
[0022] An adjusting member 5 for adjusting the telescopic length of the extension rod 2 is provided at the top of the supporting sleeve 1;
[0023] Specifically, the adjustment member 5 includes an annular block 501 arranged on the top of the support sleeve 1, the annular block 501 is sleeved on the outside of the extension rod 2, the side of the annular block 501 is inserted and connected with a movable rod 502, the end of the movable rod 502 is fixedly connected with a pressing plate 503, and a locking column 5031 for inserting the extension rod 2 is arranged on the side of the pressing plate 503 away from the movable rod 502;
[0024] It should be noted that the bottom of the annular block 501 is welded and fixed to the top of the support sleeve 1, the middle of the annular block 501 is a cylindrical hole, which is connected to the inner cavity of the support sleeve 1, and the extension rod 2 can move up and down and rotate in the cylindrical hole. The side of the annular block 501 is provided with a movable hole 5011 for the movable rod 502 to be inserted, and the movable hole 5011 is a rectangular hole. The pressing plate 503 is in close contact with the inner wall of the movable hole 5011. The inner wall of the movable hole 5011 is provided with a cylindrical hole for the locking column 5031 to be inserted, and the cylindrical hole is connected to the middle of the annular block 501;
[0025] It should be noted that the outer side of the extension rod 2 is provided with multiple sets of locking ring grooves 201 for the locking column 5031 to be inserted. The end of the locking column 5031 is truncated cone-shaped to facilitate its insertion into the locking ring groove 201, which does not affect the rotation of the extension rod 2. The base 6 is a long strip plate.
[0026] A compression spring 504 is sleeved on the outer side of the movable rod 502 and located on the side of the pressure plate 503 away from the locking column 5031. A cover plate 505 for blocking the movable hole 5011 is sleeved on the outer side of the movable rod 502.
[0027] It should be noted that the cover plate 505 is glued and fixed to the inner wall of the movable hole 5011, and a cylindrical hole for the movable rod 502 to penetrate and move is opened on the side of the cover plate 505.

The user pours concrete into the middle of the baffle plate 4 on the other side, so that the concrete flows into the reserved hole along the connecting groove 401. Since the plane side of the baffle plate 4 closes one side of the reserved hole, the concrete surface in the baffle plate 4 is higher than the top of the reserved hole, and the concrete completely fills the reserved hole. Before the concrete begins to set, the excess concrete is cut off. After the concrete reaches the strength requirement, the sealing device is removed and the wall is smoothed. This method avoids leakage when manually filling concrete, fills the reserved hole with concrete, avoids gaps in the reserved hole, and causes leakage on the wall.
