[0020] Based on the technical solution of this utility model, without changing the essential spirit of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction of the technical solution of this utility model.

[0021] Reference Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a detachable fence-type foundation pit machine, including a foundation pit machine body 1: a first fence 2 is installed at the front end of the foundation pit machine body 1, fixed columns 3 are fixedly connected to both sides of the first fence 2, a rotating column 4 is rotatably connected inside the fixed columns 3, a second fence 5 is provided on the side of the first fence 2 away from the foundation pit machine body 1, a fixed block 6 is fixedly connected to the side of the second fence 5 close to the first fence 2, a splicing rod 7 is fixedly connected to the bottom of the fixed block 6, four limiting grooves 8 are opened on the outer diameter surface of the splicing rod 7, an adjustment groove 9 is opened at both ends of the rotating column 4, an adjustment block 10 is slidably connected inside the adjustment groove 9, a limiting rod 11 is fixedly connected to the side of the adjustment block 10 close to the inside of the adjustment groove 9, and an arc-shaped block 12 is fixedly connected to both ends inside the rotating column 4.

[0022] Using the above scheme: the worker aligns the splicing rod 7 with the inside of the rotating column 4 and inserts it. After it is fully inserted, the worker rotates the rotating column 4, causing the rotating column 4 to drive the adjusting block 10 to gradually contact the arc block 12. The arc block 12 pushes the adjusting block 10 to drive the limiting rod 11 to be inserted into the limiting groove 8, thus completing the installation of the second fence 5. The above settings enable the worker to install and dismantle the second fence 5.

[0023] Reference Figure 3 and Figure 4 As shown, in this embodiment: the size of the limiting rod 11 is adapted to the size of the limiting groove 8, and the surface of the limiting rod 11 is inserted into the interior of the limiting groove 8;

[0024] With the above solution, the limiting rod 11 can be firmly inserted into the limiting slot 8, thereby effectively fixing the second fence 5 and preventing it from shaking or falling off during operation. In addition, this plug-in method is not only easy and quick to install, but also greatly improves the stability and safety of the fence structure.

[0025] Reference Figure 4 As shown in this embodiment: sliding grooves 13 are provided on both sides of the inside of the adjusting groove 9, and sliders 14 are fixedly connected to both sides of the adjusting block 10. The surface of the slider 14 is slidably connected to the inside of the sliding groove 13.

[0026] With the above solution, the slider 14 can slide smoothly inside the sliding groove 13, allowing the adjusting block 10 to move stably along the adjusting groove 9. This design not only enhances the stability of the adjusting block 10 during movement, but also ensures the accuracy of the contact between the adjusting block 10 and the arc block 12, thereby further improving the stability and reliability of the second fence 5 installation.

[0027] Reference Figure 4 As shown, in this embodiment: a return spring 15 is fixedly connected to the side of the adjusting block 10 near the inside of the adjusting groove 9, and the side of the return spring 15 away from the adjusting block 10 is fixedly connected to the inside of the adjusting groove 9.

[0028] Using the above scheme: When the worker pushes the adjusting block 10 with the arc-shaped block 12, the adjusting block 10 pushes the return spring 15 to compress and store force, and drives the limiting rod 11 to insert into the limiting groove 8. When the worker cancels the contact between the arc-shaped block 12 and the adjusting block 10, the return spring 15 releases the stored force and pushes the adjusting block 10 to move the limiting rod 11 out of the limiting groove 8, thereby facilitating the worker to quickly disassemble the second fence 5 and improving work efficiency.

[0029] Reference Figure 5 As shown in this embodiment: the interior of the fixed column 3 is provided with two annular grooves 18, and the outer diameter surface of the rotating column 4 is fixedly connected with two annular blocks 17, and the surface of the annular blocks 17 is slidably connected to the interior of the annular grooves 18.

[0030] The above solution is adopted: when the rotating column 4 rotates, the annular block 17 slides inside the annular groove 18, thereby enhancing the stability of the rotating column 4 during rotation, avoiding the shaking of the rotating column 4 during rotation, and further improving the stability of the first fence 2 installation.

[0031] Reference Figure 5 As shown in this embodiment: a return spring 16 is fixedly connected to the side of the fixed column 3 near the annular block 17, and the side of the return spring 16 away from the inside of the fixed column 3 is fixedly connected to the annular block 17.

[0032] With the above solution: when the rotating column 4 rotates, the annular block 17 is pulled by the return spring 16, which can drive the rotating column 4 to reset and rotate, so that the rotating column 4 can automatically return to the initial position after rotation, without the need for the staff to manually reset the rotating column 4, which further improves work efficiency and enhances the convenience of use.

[0033] Working principle: The worker aligns the splicing rod 7 with the inside of the rotating column 4 and inserts it. After it is fully inserted, the worker rotates the rotating column 4, causing the rotating column 4 to drive the adjusting block 10 to gradually contact the arc block 12. The arc block 12 pushes the adjusting block 10 to drive the limiting rod 11 to be inserted into the limiting groove 8, thus completing the installation of the second fence 5. The above settings enable the worker to install and dismantle the second fence 5.

[0034] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
