The top end of the plug-in section 12 is inserted into the first plug-in hole of the main body section 11. A plug-in tip 121 is arranged at the bottom end of the plug-in section 12. The plug-in tip 121 is conical. The plug-in section 12 has a first working position and a second working position. The plug-in section 12 can move relative to the main body section 11 along the axial direction of the main body section 11, so that the plug-in section 12 can move between the first working position and the second working position. The first warning sign 2 is arranged at the top end of the main body section 11, and the first warning sign 2 is used to display warning slogans. The first support seat 3 is arranged at the lower part of the main body section 11, and the first support seat 3 includes a plurality of support rods 31 arranged at intervals along the circumference of the main body section 11, and the support rods 31 have a third working position and a fourth working position, and the support rods 31 can swing relative to the main body section 11 around an axis perpendicular to the axial direction of the main body section 11, so that the support rods 31 can move between the third working position and the fourth working position, and the support rods 31 are all located in the third working position, and when the plug-in section 12 is located in the first working position, the bottom end of the support rods 31 is located below the bottom end of the plug-in section 12, and the support rods 31 are all located in the fourth working position, and when the plug-in section 12 is located in the second working position, the bottom end of the plug-in section 12 is located below the support rods 31.

When the support rod 31 is located in the fourth working position, the first end of the support rod is the bottom end of the support rod 31, and the second end of the support rod 31 is the top end of the support rod 31. The support rod 31 swings relative to the main section around an axis perpendicular to the axial direction of the main section 11 to achieve the transformation between the third working position and the fourth working position.

[0042] In the safety warning device provided in this embodiment, a plug tip 121 is provided at the bottom end of the plug section 12, and the support rods 31 are all located in the fourth working position, and when the plug section 12 is located in the second working position, the bottom end of the plug section 12 is located below the support rod 31, so that the plug tip 121 can be inserted into the soil at this time, thereby realizing the stable fixation of the safety warning device in areas such as hillsides, soft soils and muddy grounds, and no other auxiliary tools are required to fix the safety warning device. In addition, the multiple support rods 31 of the first support seat 3 are arranged at intervals along the circumference of the main section 11 of the warning rod 1, and when the support rods 31 are all located in the third working position and the plug section 12 is located in the first working position, the bottom end of the support rod 31 is located below the bottom end of the plug section 12, so that the safety warning device can be supported by the support rod 31 at this time, thereby realizing the stable placement of the safety warning device in areas such as cement ground, asphalt road and stone ground.

[0043] Optionally, an internal thread is provided in the first plug hole, an external thread is provided at the top of the plug section 12, and the plug section 12 is threadedly connected to the main section 11. The plug section 12 is threadedly connected to the main section 11, so that the plug section 12 can be driven to move relative to the main section 11 along the axial direction of the main section 11 by rotating the plug section 12. In this embodiment, the plug section 12 is coaxially arranged with the main section 11. When the plug section 12 is located at the first working position, most of the area of ​​the plug section 12 is located in the first plug hole, so that the bottom end of the support rod 31 can be located below the bottom end of the plug section 12 at this time, so that the bottom end of the support rod 31 can contact the ground to support the warning rod 1. When the plug section 12 is located at the second working position, most of the area of ​​the plug section 12 is exposed to the main section 11, so that the plug section 12 can be inserted into the soil through the plug tip 121 of the plug section 12 at this time to achieve the fixation of the warning rod 1 on the soft ground.

[0044] Alternatively, if Figure 1-Figure 4As shown, the first support seat 3 further includes a first collar 32, a second collar 33 and a positioning link 34. The first collar 32 is sleeved on the lower end of the main body section 11 and is fixedly connected to the main body section 11. The first end of the support rod 31 is hinged to the first collar 32, and the hinge axis between the support rod 31 and the first collar 32 is perpendicular to the axis of the main body section 11.

The positioning link 34 is arranged one-to-one with the support rod 31. The top end of the positioning link 34 is hinged to the second collar 33, and the bottom end is hinged to the middle part of the corresponding support rod 31. The hinge axis between the positioning link 34 and the second collar 33 and the hinge axis between the positioning link 34 and the support rod 31 are parallel to the hinge axis between the support rod 31 and the first collar 32. The length of the positioning link 34 is adjustable. The positioning link 34 mainly supports the support rod 31 . When the support rod 31 swings relative to the main section 11 , the length of the positioning link 34 changes.

[0045] Furthermore, if Figure 1-Figure 4 As shown, the positioning link 34 includes a sleeve 341 and a connecting rod 342. The first end of the sleeve 341 is hinged to the second collar 33. The first end of the connecting rod 342 is inserted into the second end of the sleeve 341, and the second end is hinged to the support rod 31. The length of the positioning link 34 is adjusted by the relative sliding between the connecting rod 342 and the sleeve 341.

[0046] Further, a limited mounting hole is provided on the connecting rod 342, and the limited mounting hole extends along the radial direction of the connecting rod 342. A first elastic member is provided in the limited mounting hole, and first limiting beads are provided at both ends of the first elastic member. A limiting hole corresponding to the first limiting beads is provided on the side wall of the sleeve 341, and the aperture of the limiting hole is smaller than the diameter of the first limiting bead. When the support rod 31 is in the third working position, the first elastic member drives a part of the first limiting bead to extend into the limiting hole. The length of the positioning connecting rod 34 is fixed by the first elastic member in cooperation with the first limiting bead. When the length of the positioning connecting rod 34 is fixed, the position of the support rod 31 is also fixed accordingly. In this embodiment, when a part of the first limiting bead extends into the limiting hole, the support rod 31 is in the third working position. The positioning effect of the first elastic member in cooperation with the first limiting bead can ensure that the support rod 31 can stably support the warning rod 1 when it is in the third working position. Since the first limiting bead only partially extends into the limiting hole and is spherical, the first limiting bead is applied to the connecting rod 342 along the axial direction of the sleeve 341, which can drive the first limiting bead to compress the first elastic member, so that the first limiting bead leaves the limiting hole, thereby releasing the positioning of the connecting rod 342 and the sleeve 341, and the support rod 31 can swing around the hinge axis between the first sleeve 32. In this embodiment, the first elastic member is a spring.

[0047] Alternatively, if Figure 1-Figure 4 As shown, the first support seat 3 also includes a third ring 35, which is sleeved on the main section 11 and fixedly connected to the main section 11. The third ring 35 is located above the second ring 33. The third ring 35 is provided with an ear plate group corresponding to the support rod 31. The ear plate group includes two ear plates 351 arranged opposite to each other. When the support rod 31 is located at the fourth working position, the second end of the support rod 31 is clamped between the two ear plates 351 of the corresponding ear plate group. The support rod 31 is clamped by the two ear plates 351 to achieve the positioning of the support rod 31 at the second working position.

[0048] Further, the ear plate 351 is provided with a first accommodating groove, a second elastic member is provided in the first accommodating groove, a second limiting bead is provided at one end of the second elastic member away from the bottom of the first accommodating groove, a first limiting groove 3421 is provided at the second end of the support rod 31, and when the support rod 31 is located at the fourth working position, the second elastic member drives the second limiting bead to partially extend into the first limiting groove 3421. The second elastic member cooperates with the second limiting bead, so that the support rod 31 is not easy to fall out from between the two ear plates 351 when it is located at the second working position. In this embodiment, the second elastic member is a spring.

[0049] Alternatively, if Figure 4 and Figure 5 As shown, the safety warning device provided in this embodiment also includes a second base 4, and the second base 4 includes a mesh shell 41, and the warning rod 1 is detachably connected to the second base 4. By providing a second base 4 with a mesh shell 41, the safety warning device provided in this embodiment can be placed on a wellhead, a drain and a construction pit without a manhole cover for safety warning, and does not affect the flow of water into the wellhead or drain. In addition, the mesh shell 41 can also filter leaves and garbage to avoid clogging the wellhead or drain. In this embodiment, the mesh shell 41 is made of metal so that the mesh shell 41 has a certain hardness, such as steel or aluminum alloy. The specific shape of the mesh shell 41 can be selected as needed, such as a funnel shape or a square shape.

[0050] Furthermore, if Figure 4 and Figure 5 As shown, the second base 4 also includes a plug-in tube 42 fixedly arranged in the mesh housing 41. When the plug-in section 12 is located in the second working position, the plug-in section 12 can be inserted into the plug-in tube 42.

[0051] Optionally, a second plug hole is provided at the bottom end of the first warning sign 2, and the top end of the main body section 11 is plugged into the second plug hole. Thus, a detachable connection between the first warning sign 2 and the warning rod 1 is achieved. Preferably, a second limiting groove extending along the circumference of the main body section 11 is provided at the upper part of the main body section 11, and a second receiving groove extending along the radial direction of the second plug hole is provided on the hole wall of the second plug hole, and a third elastic member is provided in the second receiving groove, and a third limiting bead is provided at one end of the third elastic member away from the bottom of the second receiving groove. When the top end of the main body section 11 is plugged into the second plug hole, the third elastic member drives the third limiting bead to partially extend into the second limiting groove, thereby making the connection between the first warning sign 2 and the warning rod 1 more stable.

[0052] Alternatively, if Figure 1-Figure 4 As shown, the safety warning device provided in this embodiment also includes a second warning sign 5, which is arranged in the middle of the length direction of the main body section 11 and is detachably connected to the main body section 11.
