[0036] The main body assembly includes a base plate 11 and a set of brackets 12;
[0037] The brackets 12 are respectively fixed to the edges of both sides of the top of the bottom plate 11;
[0038] The bottom plate 11 is used to place other components, and the brackets 12 are respectively fixed to the left and right edges of the top of the bottom plate 11, and the brackets 12 are used to support other components;
[0039] Auxiliary support assembly, the auxiliary support assembly includes a connecting rod 21, a telescopic rod 22, and a connecting plate 23;
[0040] The connecting rod 21 is fixed between the outer sides of the bracket 12, the telescopic rod 22 is placed obliquely below the two ends of the connecting rod 21, and the connecting plate 23 is fixed to the bottom end of the telescopic rod 22;
[0041] The connecting rod 21 is used to place other components, the telescopic rod 22 is used to support the connecting rod 21 and the bracket 12 to prevent shaking, the telescopic rod 22 is placed below the front and rear ends of the connecting rod 21, and the connecting plate 23 is used to place the support nails 24;
[0042] A group of support nails 24 are passed through the top and bottom ends of the connecting plate 23, and a square plate 25 is fixedly connected to the top edge of the telescopic rod 22;
[0043] Each connecting plate 23 has two supporting nails 24, and the supporting nails 24 are passed through the connecting plate 23 and inserted into the soil, so that the supporting nails 24 limit the telescopic rod 22, thereby allowing the telescopic rod 22 to limit the connecting rod 21 and the bracket 12;
[0044] The top of the square plate 25 extends to both sides of the connecting rod 21, the inner side of the square plate 25 fits with the connecting rod 21, and the outer sides of the fitting parts of the two sides are movably connected with movable shafts 26;
[0045] A square plate 25 is provided to flexibly connect the telescopic rod 22 and the connecting rod 21, and a movable shaft 26 is provided to connect the square plate 25 and the connecting rod 21, and at the same time, the telescopic rod 22 is flexibly extended through the movable shaft 26;
[0046] Working principle:
[0047] When the assembly is not in use, the telescopic rod 22 is in a horizontal state, and the telescopic rod 22 is located below the connecting rod 21. When the assembly is in use, the telescopic rod 22 is unfolded by hand, and the telescopic rod 22 is opened through the movable shaft 26. When the telescopic rod 22 is unfolded to a suitable angle, the push is stopped;
[0048] Then, the telescopic rod 22 is pulled by hand, and the bottom of the telescopic rod 22 drives the connecting plate 23 to move above the ground, so that the connecting plate 23 is in contact with the ground, and then the supporting nail 24 is pushed hard so that the bottom end of the supporting nail 24 is inserted into the ground, and then the pushing of the supporting nail 24 is stopped. At this time, the supporting nail 24 limits the telescopic rod 22, so that the telescopic rod 22 supports the connecting rod 21 and the bracket 12;
[0049] In the above steps, the bracket 12 is limited and supported through the interaction between the telescopic rod 22 and the supporting nail 24 .
[0050] See also Figure 1-Figure 2 , Figure 4 As shown, this embodiment is based on the above embodiment 1 and also includes:
[0051] Limiting components;

[0059] The drilling device 13 is used for positioning the drilling, and the support rod 14 is used for supporting the bottom plate 11 and other components such as the upper bracket 12;
[0060] Working principle:
[0061] When the telescopic rod 22 is not in use, the lower part of the telescopic rod 22 is pushed by hand, and the lower part of the telescopic rod 22 enters the upper part of the telescopic rod 22, and then the telescopic rod 22 is rotated inward by hand, and the telescopic rod 22 rotates through the movable shaft 26. When the telescopic rod 22 rotates to the inner side, it stops rotating;
[0062] The cylinder 32 is started, and the cylinder 32 drives the moving rod 33 to move upward, so that the moving rod 33 drives the placement plate 34 and the limiting frame 35 to move upward.
