[0021] Specifically, the inner steel pipe 11 and the outer steel pipe 10 are slidably connected to guide the movement of the inner steel pipe 11 .

[0022] Specifically, after the operator completes the welding operation on the grid ball, the operator controls the rack rail 16 to drive the inner steel pipe 11 to move downward to separate it from the grid ball, thereby facilitating the disassembly of the base for reuse.

[0023] Specifically, the height of the outer steel pipe 10 is 300mm, the telescopic length of the inner steel pipe 11 is 0-250mm, the diameter of the steel pipe can be 150-300mm, the inner steel pipe 11 and the outer steel pipe 10 differ by one specification, and the specific dimensions of the inner steel pipe 11 and the outer steel pipe 10 can be designed according to the size of the grid ball.

[0024] Specifically, the device can be used as a base for a grid structure welding ball or a bolt ball and can be reused.

[0025] In an embodiment of the present invention, Figure 1-6As shown, the fine-tuning base includes: a fixed base, an adjusting base and an adjusting bolt 20; the fixed base is formed by splicing three first fan-shaped steel plates 17, a threaded block 18 is provided on the top of the first fan-shaped steel plate 17, and the outer steel pipe 10 is fixed on the top of the first fan-shaped steel plate 17; the adjusting base is formed by splicing three second fan-shaped steel plates 19, and the second fan-shaped steel plate 19 is located below the first fan-shaped steel plate 17; one end of the adjusting bolt 20 passes through the threaded block 18 and the first fan-shaped steel plate 17 in sequence, and the bottom of the adjusting bolt 20 is rotatably connected to the second fan-shaped steel plate 19.

[0027] Specifically, a balancing device 30 is provided on the first sector-shaped steel plate 17 so that the operator can observe whether the device is level when adjusting the second sector-shaped steel plate 19 .

[0028] Specifically, since the fixed base and the adjustable base are both composed of three fan-shaped steel plates, and each fan-shaped steel plate is provided with an independent adjusting bolt 20, this design can better adapt to irregular or inclined ground, thereby preventing the grid ball placed on the top of the device from accidentally falling due to the tilt of the device.

[0029] In an embodiment of the present invention, Figure 1-6 As shown, the triangular fixing frame includes: two first connecting rods 21, two second connecting rods 22 and two third connecting rods 23; one end of the two first connecting rods 21 is fixedly connected to the outer steel pipe 10, and the other end of the two first connecting rods 21 is rotatably connected to the two ends of the first rotating shaft 12; one end of the two second connecting rods 22 is fixedly connected to the outer steel pipe 10, and the other end of the two second connecting rods 22 is rotatably connected to the two ends of the second rotating shaft 13; one end of the two third connecting rods 23 is fixedly connected to the outer steel pipe 10, and the other end of the two third connecting rods 23 is rotatably connected to the two ends of the first rotating shaft 12 and the second rotating shaft 13.
