The reset member 12 is a second spring, the second spring corresponds to the locking head 7 one by one, the second spring is sleeved on the outer wall of the locking head 7, and the second spring is located between the limiting ring 22 and the inner wall of the adjusting cylinder 8, so as to give the limiting ring 22 and the locking head 7 a tendency to abut on the outer wall of the adjusting cylinder 8 in the direction close to the adjusting cylinder 8.

[0076] When the moving rod 10 drives the adjusting cylinder 8 to move to the position where the outer wall of the first section 81 abuts on the locking head 7, the arc head section 72 of the locking head 7 enters the sliding groove, at this time, when the connecting ear 202 moves to the position opposite to the locking head 7, the arc head section 72 can be clamped into the connecting ear 202, so that the arc head section 72 preliminarily limits the connecting ear 202. When it is necessary to adjust the position of the connecting ear 202, the connecting ear 202 is pried to extrude the arc head section 72 through the arc surface of the arc head section 72, so that the arc head section 72 is extruded into the cylinder wall of the main cylinder 15, so that the connecting ear 202 can move, and the locking head 7 drives the adjusting cylinder 8 to move in the activity space 9 to adapt to the movement of the locking head 7.

[0077] When the moving rod 10 drives the adjusting cylinder 8 to move to the position where the outer wall of the third section 83 abuts on the locking head 7, the locking head 7 is extruded to be inserted into the connecting ear 202 together with the straight section 71 and the arc head section 72 through the guidance of the second section 82, so that the locking head 7 locks the connecting ear 202, at this time, the connecting ear 202 cannot be moved by prying.

[0078] The implementation principle of the multifunctional safety guardrail in the embodiment of the application is that the first section 81 or the third section 83 of the adjusting cylinder 8 is driven to abut on the locking head 7 by moving the moving rod 10 in the thread, when the first section 81 of the adjusting cylinder 8 abuts on the locking head 7, the arc head section 72 of the locking head 7 is inserted into the connecting ear 202, at this time, the connecting ear 202 can be extruded to adjust the position of the connecting ear 202 by prying the connecting ear 202. When the third section 83 of the adjusting cylinder 8 abuts on the locking head 7, the locking head 7 locks the connecting ear 202.

[0079] The above are the preferred embodiments of the application, which do not limit the protection scope of the application, therefore: any equivalent changes made on the structure, shape and principle of the application should be covered within the protection scope of the application.
