Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Please see the attached Figure 1 - Attachment Figure 2 The U-shaped plate 3 is fixedly connected to the left and right sides of the outer wall of the U-shaped plate 3, and a locking hole 17 is opened in the middle of the inner side of the U-shaped plate 3. The inner side of the locking hole 17 is locked with a locking block 16, and the outer wall of the locking block 16 is locked with a locking plate 15. The front and rear sides of the locking plate 15 are fixedly connected to the L-shaped plate 10, and the outward side of the L-shaped plate 10 is threadedly connected with a bolt 9. The adjacent locking plates 15 and the locking blocks 16 are locked with inclined plates 12. The outward side of the locking plates 15 is fixedly connected to the connecting plate 4. The bottom end of the support column 1 is provided with an enlarging mechanism 2, which is used to increase the ground contact area. The inner bottom end is fixedly connected to a magnet 11, and the bottom end of the inclined plate 12 is fixedly connected to a magnet 2 14. The bottom end of the magnet 2 14 is adsorbed with the bottom end of the magnet 11.

[0031] Specifically, the U-shaped plate 3 serves as an important basic structure and plays an indispensable role. The engaging hole 17 carefully opened in the middle of the inner side not only demonstrates the ingenuity of the design, but also provides the possibility for subsequent assembly and fixation. The size of the engaging hole 17 has been precisely calculated to ensure a perfect fit with the engaging block 16. The engaging block 16 is a key component of the connection. Its outer wall is tightly engaged with the engaging plate 15 to form a stable and reliable connection point. The front and rear sides of the engaging plate 15 are firmly fixed with L-shaped plates 10. These L-shaped plates 10 are provided with threaded holes on the outward side for installing bolts 9. The introduction of bolts 9 not only enhances the stability of the structure, but also the outward side of the engaging plate 15 is fixed with connecting plates 4. These connecting plates 4 can be further connected and expanded according to actual needs, making the entire structure more flexible and customizable.

[0032] Please see the attached Figure 3 The enlarging mechanism 2 includes a bottom plate 201 and a T-shaped slide plate 205. The middle part of the top of the bottom plate 201 is fixedly connected to the bottom end of the support column 1. A T-shaped groove 210 is provided at the inner bottom end of the bottom plate 201. The outer wall of the T-shaped groove 210 is fixedly connected to an enlarging plate 209. The left and right sides of the enlarging plate 209 are provided with elongated holes 208. The inner side of the elongated hole 208 is slidably connected to the telescopic plate 207. The top of the outer wall of the T-shaped slide plate 205 is engaged with a buckle 204. The top of the bottom plate 201 is provided with a clamping hole 203. The bottom end of the bottom plate 201 is fixedly connected with an anti-slip pad 202. The inner side of the clamping hole 203 is engaged with the bottom end of the buckle 204. The outward side of the telescopic plate 207 is fixedly connected to a T-shaped column 206.

[0033] Specifically, the base plate 201 is a stable foundation for the entire structure, and the middle of its top is fixed to the bottom end of the support column 1 through a solid connection to ensure the stability and load-bearing capacity of the entire structure. The design of this T-slot 210 allows for precise docking with specific accessories or components, providing the possibility for diversified configuration of the structure. In order to enhance the stability and durability of the T-slot 210, its outer wall is fixedly connected to the enlargement plate 209. The enlargement plate 209 not only increases the force-bearing area of ​​the T-slot 210, but also improves its overall strength. These long holes 208 allow the telescopic plate 207 to slide inside it, thereby realizing the telescopic function of the structure. The introduction of the telescopic plate 207 allows the entire structure to be adjusted as needed to adapt to different working environments or needs.

[0034] Please see the attached Figure 1 - Attachment Figure 2 , the top of the outer wall of the support column 1 is fixedly connected with a warning light 8, the outward side of the connecting plate 4 is fixedly connected with a protective block 5, the other end of the bolt 9 is threadedly connected to the front and rear sides of the outer wall of the U-shaped plate 3, the front bottom end of the support column 1 is fixedly connected with a control button 6, the control button 6 and the warning light 8 are electrically connected, the upper and middle ends of the outer wall of the support column 1 are fixedly connected with a fluorescent plate 7, and multiple fluorescent plates 7 are fixedly connected at the same horizontal height;

[0035] Specifically, by fixing the protective blocks 5 on the outward side of the connecting plate 4, these protective blocks 5 not only serve as aesthetic decoration, but more importantly, they can protect the connecting plate 4 from external impact and scratches, thereby extending the service life of the overall structure. The front bottom end of the support column 1 is fixedly connected to the control button 6, which not only controls the start and stop of the entire device, but is also electrically connected to the warning light 8. When the equipment is abnormal or requires maintenance, the control button 6 will trigger the warning light 8 to light up, alerting the operator. This design greatly improves the safety and reliability of the equipment and reduces the probability of accidents.

[0036] Working principle: When the steel pipe column needs to be mortised, first fix the connecting plate 4 with the snap plate 15, then fix the U-shaped plate 3 with the outer wall of the support column 1, and then pick up the snap block 16 and snap it into the inner side of the snap hole 17 for stabilization, then slide the snap plate 15 with the outer wall of the snap block 16 to make the L-shaped plate 10 fit on the outer wall of the U-shaped plate 3, and then twist the bolt 9 to limit the L-shaped plate 10, and finally pick up the inclined plate 12 and snap it into the gap formed between the snap plate 15 and the snap block 16, so that the snap plate 15 is more stable:

[0037] After that, the support column 1 is fixedly connected to the top of the base plate 201, and the T-shaped slide plate 205 slidably connected on the T-shaped slot 210 is pushed outward, so that the enlarged plate 209 moves outward along the inner side of the base plate 201. When the enlarged plate 209 is completely moved out, the telescopic plate 207 on the inner side of the elongated hole 208 is pulled outward in cooperation with the T-shaped column 1 206, thereby increasing the contact area between the bottom end of the base plate 201 and the ground. Finally, the buckle 204 is snapped into the inner side of the corresponding snap hole 203 to limit the T-shaped slide plate 205.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
