[0031] Reference Figure 8 As shown, the cross-sectional shape of the insert rod 10 fits the inner wall of the rotating rod 9. When the insert rod 10 rotates, it can drive the rotating rod 9 to rotate. And when the bolt 3 moves downward and inserts into the ground, the insert rod 10 can move downward along the inside of the rotating rod 9 following the bolt 3. When inserting the bolt 3 into the ground, the fixed rod 12 cooperates with the fixing hole to fix the position of the rotating rod 9, preventing the rotating rod 9 and the insert rod 10 from rotating, thereby limiting the position of the bolt 3 and preventing the bolt 3 from rotating when inserted into the ground. The inner side wall of the nut 7 is provided with a thread that fits the bolt 3.

[0032] A rotating shaft 19 is rotatably connected to the upper end surface of the bearing plate 23. A central gear 22 is fixedly connected to the upper end of the rotating shaft 19. A slide bar 16 is fixedly installed between the two connecting plates 14. Sleeve plates 21 are sleeved on the outer part of the slide bar 16 near both ends.

And the output end of the switch button 13 is electrically connected to the input end of the warning lamp 4. Both ends of the shrapnel 17 move along the outer part of the slide bar 16 and move closer to each other, generating deformation, so that the highest point of the shrapnel 17 touches and presses the switch button 13, turning on the warning lamp 4.

[0034] After the base body 1 is fixed to the ground by four bolts 3 and four nuts 7 to fix the tower leg 5, the fixing rod 12 is pulled out from the mounting shell 2, so that the fixing rod 12 is removed from the fixing hole, releasing the fixation of the fixing ring 11, and thus releasing the fixation of the rotating rod 9. When the bolt 3 loosens and rotates in the loosening direction, the inserting rod 10 and the rotating rod 9 rotate along with the bolt 3. Cooperating with the transmission belt 18, it can drive the rotating shaft 19 installed on the bearing plate 23 to rotate simultaneously, thereby driving the central gear 22 to rotate, driving the two racks 20 to move horizontally simultaneously through the cooperation of the slide plates 28, driving the two sleeve plates 21 to move along the slide bar 16 simultaneously, and move closer to each other, pushing both ends of the shrapnel 17 to move along the outer part of the slide bar 16 and move closer to each other, generating deformation, compressing the spring, so that the highest point of the shrapnel 17 touches and presses the switch button 13, turning on the warning lamp 4, thereby prompting the staff that the bolt 3 has loosened. Through the above operations, it is possible to quickly and automatically detect that the bolt 3 has loosened, facilitating the staff to promptly handle the loosened bolt 3 and avoiding affecting the stability of the base body 1 and the tower leg 5.

[0035] A housing 8 is sleeved outside the nut 7. A plurality of tooth blocks are fixedly installed on the outer wall of the housing 8.

The inner side wall of the housing 8 is shaped to fit the shape of the nut 7. When the housing 8 rotates, the nut 7 can be driven to rotate simultaneously.

[0036] A motor is installed on the bottom surface of the outer shell 6, and the output end of the motor is connected to one end of the connecting shaft 25. An annular groove 26 is formed on the upper surface of the base body 1 and directly below the housing 8. A plurality of sliders 27 are slidably installed inside the annular groove 26, and the upper ends of the plurality of sliders 27 are fixedly connected to the housing 8.

[0037] Specifically, when the base body 1 is installed and fixed by the bolt 3 and the nut 7, the motor installed on the bottom surface of the outer shell 6 drives the connecting shaft 25 to rotate, thereby driving the transmission gear 24 to rotate. Cooperating with each tooth block, the housing 8 can be driven to rotate, and then the nut 7 is driven to rotate. The slider 27 slides along the annular groove 26 following the housing 8, which can limit the rotation position of the housing 8 and the nut 7 inside the housing 8, so that the nut 7 always rotates at a fixed position, thereby driving the bolt 3 to move downward and insert into the ground to fix the base body 1. Through the above operations, the base body 1 can be automatically installed and fixed without using external tools to operate the nut 7 and the bolt 3, making the installation operation more convenient and efficient.
