[0007] As a preferred technical solution of the utility model, limit grooves are opened on both sides of the second slide groove, and limit blocks are provided on both sides of the spring block. The limit blocks slide into the limit grooves to limit the stroke of the spring block and stabilize the movement trajectory of the spring block.

[0008] As a preferred technical solution of the utility model, the diameter of the positioning groove is smaller than the diameter of the limiting bead, and there are multiple groups of limiting beads, the third sliding groove and the first return spring, and a circular array is arranged inside the limiting sleeve, so that the limiting bead pops out and cooperates with the positioning groove, so that the embedded bolt is limited inside the limiting sleeve, thereby realizing the adjustment of the embedded depth of the embedded bolt.

[0009] As a preferred technical solution of the utility model, there are multiple card slots, and the card slot array is arranged on the side of the first sliding slot.

[0019] The working principle of the utility model is as follows: when the embedded bolt 4 is installed on an irregular ground, the spring block 12 is pressed. At this time, the second return spring 11 is compressed to make the spring block 12 disengage from the card slot 13, so that the supporting leg 9 can slide up and down in the supporting frame 8, and the spring block 12 is released. The spring block 12 will be re-stuck in the card slot 13 to achieve positioning. According to the actual situation, the heights of the four groups of supporting legs 9 are adjusted in sequence, so that the four groups of supporting legs 9 cooperate with each other to align the positioning steel plate 1, and then the embedded bolt 4 is inserted into the limiting sleeve 2. During the insertion process, the embedded bolt 4 will squeeze the limiting bead 6, and the limiting bead 6 will move toward the inside of the third slide groove 201 due to the compression of the first return spring 5. When the limiting bead 6 and the positioning groove 7 are in the same position, the limiting bead 6 will pop out and be stuck in the position of the positioning groove 7, so that the embedded bolt 4 will pause during the insertion process to remind the staff of the insertion depth, ensure the insertion depth of the embedded bolt 4, ensure the stability of the device, and prevent problems such as uneven force on the structure after being connected to the tower base, or inability to dock during installation.
