[0049] One end of the guide groove 22 close to the mounting portion 21 is not connected to the mounting portion 21 (spaced a certain distance apart).

[0050] Please see attached Figure 8 and attached Figure 9 In a specific implementation of this embodiment, from the end away from the main rod 2 provided with the mounting portion 21 to the end close to the main rod 2 provided with the mounting portion 21, the guide groove 22 includes:

[0051] a stop groove 221, wherein the stop groove 221 abuts against the protrusion 514 of the protrusion piece 51 when the protrusion piece 51 is at the highest protrusion height;

[0052] A first groove 222, wherein the depression depth of the first groove 222 toward the axis of the main rod 2 is less than or equal to the depression depth of the retaining groove 221 toward the axis of the main rod 2;

[0053] a stop plate 223, wherein the stop plate 223 is disposed between the stop groove 221 and the first groove 222;

[0054] The second groove 224 is connected to the first groove 222 , and the depression depth of the second groove 224 toward the axis of the main rod 2 is smaller than the depression depth of the first groove 222 toward the axis of the main rod 2 .

[0055] In the utility model, by providing the stop groove 221 and the stop plate 223, a fixed position of the warning fence rod in the retracted state is provided, ensuring that the retracted state is stable and will not open abnormally.

[0056] Specifically, in the state where the warning railing is retracted (the extension assembly 4 is retracted), the raised piece 51 of the control assembly 5 is at the highest raised height, the raised portion 514 of the raised piece 51 abuts against the stop groove 221, and the raised portion 514 blocks on the side of the stop plate 223 close to the stop groove 221;

[0057] In the state where the warning railing is semi - unfolded (the extension assembly 4 is semi - unfolded), the raised piece 51 of the control assembly 5 is at the middle raised height, the raised portion 514 of the raised piece 51 abuts against the first groove 222, and the raised portion 514 blocks at the position between the first groove 222 and the second groove 224 (at the end of the first groove 222 close to the second groove 224);

[0058] In the state where the warning railing is fully unfolded (the extension assembly 4 is fully unfolded), the raised piece 51 of the control assembly 5 is at the lowest raised height, the raised portion 514 of the raised piece 51 abuts against the second groove 224, and the raised portion 514 blocks at the position between the second groove 224 and the mounting portion 21 of the main rod 2 (at the end of the second groove 224 close to the mounting portion 21);

[0059] That is: in this embodiment, the warning railing has three states (retracted state, semi - unfolded state, and fully unfolded state); for unfolding, there are two states, namely semi - unfolded and fully unfolded; it can be understood that in order to provide corresponding unfolding conditions for more application scenarios, more grooves with different depths can be set to provide more different unfolding states. For example, in another specific embodiment, there are four unfolding states, namely: quarter - unfolded state, semi - unfolded state, three - quarter - unfolded state, and fully unfolded state.

[0060] In another specific embodiment of this embodiment (not shown in the figure), the extension length of the guide groove 22 along the axis direction of the main rod 2 is equal to the maximum stroke that the bone bundle 42 can move along the axis direction of the main rod 2; the maximum stroke that the bone bundle 42 can move along the axis direction of the main rod 2 refers to the stroke that the bone bundle 42 can move along the axis direction of the main rod 2 when the raised piece 51 is in the state of the lowest raised height;

[0061] One end of the guide groove 22 close to the mounting portion 21 is connected to the mounting portion 21;

[0062] From the end far away from the main rod 2 where the mounting portion 21 is provided to the end close to the main rod 2 where the mounting portion 21 is provided, the guide groove 22 successively includes:

[0063] The first groove is provided at one end of the main rod 2 away from the mounting portion 21. When the raised piece 51 is at the highest raised height, the first groove abuts against the raised portion 514 of the raised piece 51.

[0064] The second groove communicates with the first groove. The depth of the second groove recessed toward the axis of the main rod 2 is less than the depth of the first groove recessed toward the axis of the main rod 2.

[0065] The third groove communicates with the second groove. The depth of the third groove recessed toward the axis of the main rod 2 is less than the depth of the second groove recessed toward the axis of the main rod 2.

[0066] Specifically, the difference between this embodiment and the above embodiment lies in the setting of the gear state. In this embodiment, when the raised piece 51 is at the highest raised height, the raised portion 514 of the raised piece 51 abuts against the first groove and blocks the connection between the first groove and the second groove; when the raised piece 51 is at the middle raised height, the raised portion 514 of the raised piece 51 abuts against the second groove and blocks the connection between the second groove and the third groove; when the raised piece 51 is at the lowest raised height, the raised portion 514 of the raised piece 51 abuts against the third groove and blocks the connection between the third groove and the main rod 2 (or the mounting portion 21).

[0067] Please refer to the appendix Figure 1 to the appendix Figure 3 In a specific embodiment of this embodiment, the warning railing further includes: a stop collar 6. The outer diameter of the stop collar 6 is greater than or equal to the diameter of the main rod 2. The stop collar 6 is fixedly sleeved on the outer periphery of the main rod 2.

[0069] When the bone bundle 42 is at the farthest position moving away from the mounting portion 21, one end of the bone bundle 42 away from the mounting portion 21 abuts against one end of the stop collar 6 close to the mounting portion 21.

[0070] In a specific embodiment of this implementation, a spring (not shown in the figure) is provided at one end of the bone bundle 42 that abuts against the stop collar 6. This spring is in a compressed state when the extension assembly 4 is in a retracted state and a semi-expanded state; when the extension assembly 4 is in a fully expanded state, the spring is in a natural state (neither compressed nor stretched).

[0071] In another specific implementation manner of this embodiment, a spring (not shown in the figure) is provided between the bone bundle 42 and the mounting portion 21. The spring is in a stretched state when the stretching assembly 4 is in the retracted state and the semi-expanded state; when the stretching assembly 4 is in the fully-expanded state, the spring is in a natural state (neither compressed nor stretched).

[0072] In another specific implementation manner of this embodiment, an elastic cord (not shown in the figure) is provided between the bone bundle 42 and the mounting portion 21. The elastic cord is in a stretched state when the stretching assembly 4 is in the retracted state and the semi-expanded state; when the stretching assembly 4 is in the fully-expanded state, the elastic cord is in a natural state (not stretched).

[0073] In the present utility model, by providing the spring / elastic cord, the stretching assembly 4 has a tendency to move upward (towards the direction close to the mounting portion 21), and there is no need to manually push the bone bundle 43 to move.

[0089] In the utility model, by setting the second piece 522 and the reset spring 53, the raised height of the raised plate 512 is pushed to change. When resetting, the second piece 522 is moved in the opposite direction, and the reset spring 53 assists in resetting through pulling force to ensure the normal implementation of the function.

[0090] In a specific implementation of this embodiment, the position of the bone bundle 42 accommodating the control assembly corresponds to the position of the second piece 522 and is marked with a gear scale (not shown in the figure);
