[0023] The auxiliary support seat 52 is configured as a triangular support structure; here, the auxiliary support seat 52 is configured as a triangular support structure, and the stability of the triangle is utilized to enable it to better support the main support seat 51.

[0024] The adjusting support mechanism 6 includes a support tube 61, a sliding support 62, a limit block 63 and a support column 64. The top outer wall of the first support part 3 is provided with a support tube 61, and a sliding support 62 is slidably installed inside the support tube 61. The side outer wall of the sliding support 62 is symmetrically provided with a limit block 63, and the side inner wall of the support tube 61 is symmetrically provided with a limit groove. The limit block 63 and the limit groove are slidably installed. The top outer wall of the sliding support 62 is provided with a support column 64, and the protruding end of the support column 64 is provided above the support tube 61, and the protruding end of the support column 64 is connected to the bottom outer wall of the second support part 4. The side outer wall of the support column 64 near the bottom end is provided with a docking thread groove 65, and the side outer wall of the support tube 61 is provided with a positioning thread groove 66 at equal intervals. The docking thread groove 65 and the positioning thread groove 66 There is a threaded installation between the positioning bolt 67; when the overall support height of the device needs to be adjusted according to the support height of the support part 2 of the post-casting strip, the positioning bolt 67 needs to be unscrewed from the inside of the positioning thread groove 66, and then the support column 64 changes from a locked state to an active state, and then the second support part 4 is directly pulled to pull the support column 64 to a suitable support height, and then the movement of the support column 64 will automatically drive the sliding support 62 to move, and then the movement of the sliding support 62 will automatically drive the limit block 63 to slide inside the limit groove. Here, the setting of the sliding support 62 and the limit block 63 has the effect of limiting support for the movement of the support column 64, and then when the support column 64 moves to the specified height, the positioning bolt 67 is passed through the positioning thread groove 66 at the corresponding position and screwed to the bottom end of the docking thread groove 65 to complete the installation.

[0025] The opening diameter of the docking thread groove 65 is equal to the opening diameter of the positioning thread groove 66; here, the docking thread groove 65 and the positioning thread groove 66 are set to have the same opening diameter so that the above-mentioned positioning bolt 67 is not easy to loosen after installation.

When locking sill 752 with latch lock 71 is in the action of latching in the bolt 714, latch lock 7 is in the action of latching in the bolt 715 and the bolt 716, and latch lock 7 is in the effect of the impact of the bolt 714 on the bolt 716. When latch lock 7 is in the action of latching in the bolt 714, latch lock 7 is in the effect of the impact of the bolt 716.

[0027] When the present invention is in use, it is first necessary to adjust the overall support height of the device according to the support height of the support portion 2 to be supported by the post-casting strip. At this time, it is first necessary to unscrew the positioning bolt 67 from the inside of the positioning thread groove 66, so that the support column 64 changes from the locked state to the active state, and then directly pull the second support portion 4 to pull the support column 64 to the appropriate support height, and then the movement of the support column 64 will automatically drive the sliding support member 62 to move, and then the movement of the sliding support member 62 will automatically drive the limit block 63 to slide inside the limit groove, and the setting of the sliding support member 62 and the limit block 63 here plays a role of limiting support for the movement of the support column 64, and then when the support column 64 moves to the specified height, the positioning bolt 67 is passed through the positioning thread groove 66 at the corresponding position and screwed to the bottom end of the docking thread groove 65 to complete the installation;

[0028] Then, the support seat 71 is clamped to the bottom end of the supported part 2 of the post-cast strip at the corresponding position. The setting of the friction pad 73 here achieves the effect of stable support by increasing the contact friction between the supported part 2 of the post-cast strip and the device. When the device needs to be positioned and installed at a specified position above the ground body 1, it is only necessary to adjust the device to a suitable position and place it at the specified position above the ground body 1, and then drive the ground nail 55 through the positioning groove 54 and into the inside of the ground body 1.
