[0024] The invention comprises a pole body 1, a base 2 is provided at the bottom of the pole body 1, anchor bolts 3 are fixedly installed at the four corners and the center of the bottom end of the base 2, ropes 14 are fixedly installed on both sides of the outer wall of the anchor bolt 3, auxiliary bolts 6 are provided at one end of multiple ropes 14, grooves 7 are provided in the middle of multiple auxiliary bolts 6, gears 8 are rotatably installed in the middle of the bottom end of the inner wall of multiple grooves 7, multiple racks 9 are meshed and connected to the outer walls of the multiple gears 8, one side of the multiple racks 9 is slidably connected to the inner wall of the auxiliary bolt 6, non-adjacent ends of multiple groups of racks 9 are fixedly connected to plug rods 10, and one end of multiple plug rods 10 is movable between adjacent auxiliary bolts 6 Through the rotation of the gear 8, multiple racks 9 can be driven to move horizontally, and then the insertion rod 10 is further driven to penetrate the auxiliary bolt 6. After that, the insertion rod 10 is horizontally connected to the ground, which can increase the grip and friction with the ground, thereby improving the grip effect of the auxiliary bolt 6 and further improving the stability of the device. The size of the bottom of the base 2 is larger than the size of the top of the base 2. The design of the trapezoidal base 2 can provide a larger support area, thereby increasing the contact area between the base 2 and the ground, improving the stability of the entire device structure, and helping to resist the effects of external wind and other loads on the holding pole body 1, reducing the risk of tilting or shifting the holding pole body 1.

[0025] In this embodiment, a top cover 11 is installed on the top of each of the auxiliary bolts 6, and a motor 12 is embedded in the middle of the bottom of each of the top covers 11. The output ends of each of the motors 12 are fixedly connected to the middle of the top of each of the adjacent gears 8. The setting of the motor 12 drives the gear 8 to rotate, and further controls the lateral extension and retraction of the insertion rod 10 outside the auxiliary bolt 6.

[0026] In this embodiment, a fixing ring 13 is fixedly installed in the middle of the top of each of the multiple top covers 11, one end of each of the multiple ropes 14 is fixedly wound around adjacent fixing rings 13, the sizes of the multiple auxiliary bolts 6 are consistent, and the lengths of two adjacent ropes 14 are consistent. The setting of the rope 14 serves to assist in the connection between the auxiliary bolts 6 and the base 2.

[0027] In this embodiment, an extension sleeve 4 is fixedly installed on the top of the base 2, and the bottom of the pole body 1 is sleeved inside the extension sleeve 4. The bottom of the pole body 1 and the inner wall of the extension sleeve 4 fit each other, and the extension sleeve 4 and the bottom of the pole body 1 are threadedly connected by the set fastening bolts 5.

Further, through the connection between the rope 14 and the fixing ring 13, the rope 14 drives the auxiliary bolt 6 to be stretched, and the auxiliary bolt 6 is penetrated into the soil. The support force of the bottom is increased through the cooperation between the rope 14 and the auxiliary bolt 6. At this time, the driving motor 12 drives the gear 8 to rotate, and the gear 8 engages with multiple racks 9, thereby driving the racks 9 to slide on the inner wall of the groove 7, and further drives the insertion rod 10 to penetrate the outside of the auxiliary bolt 6, thereby increasing the lateral fixing strength between the rod and the soil, thereby improving the grip of the auxiliary bolt 6 and further improving the stability of the device.
