The fixing portion 1 includes a first vertical rod 11, a second vertical rod 12 disposed at two sides of the first vertical rod 11, and a first cross rod 13 erected between the first vertical rod 11 and the second vertical rod 12. The lifting part 2 includes a first lifting rod 21, a second lifting rod 22 disposed on both sides of the first lifting rod 21, and a second cross rod 23 erected between the first lifting rod 21 and the second lifting rod 22. First pole setting 11 and second pole setting 12 are hollow structure, and first lifter 21 is inserted in first pole setting 11 with liftable ground, and second lifter 22 is inserted in second pole setting 12 with liftable ground, and first pole setting 11 is equipped with first fixed knot who is used for fixed first lifter 21 and constructs 3, and second pole setting 12 is equipped with second fixed knot who is used for fixed second lifter 22 and constructs 4.

Referring to fig. 2, the first fixing structure 3 includes a first fixing block 31 and a first elastic member 32, the first fixing block 31 faces the first lifting rod 21, and the first elastic member 32 is disposed between the first fixing block 31 and the first lifting rod 21. The end of the first fixed block 31 is formed to have an acute angle in which the upper end is horizontal and the lower end is inclined, the first elevation bar 21 is provided with first saw teeth 211 toward the first fixed block 31, and the first saw teeth 211 are formed to have an acute angle in which the upper end is inclined and the lower end is horizontal. When the lifting part 2 is lifted up, the inclined surface of the first saw tooth 211 may press the inclined surface of the first fixing block 31 from bottom to top, so that the first fixing block 31 slides toward the first elastic member 32, and the first elastic member 32 contracts, so that the first lifting lever 21 may smoothly slide over the first fixing block 31. When removing the pulling force that lifting unit 2 rose, lifting unit 2 slides down because of the dead weight, and first fixed block 31 stretches into first sawtooth 211 under the elastic force effect of first elastic component 32 this moment, and the plane of first sawtooth 211 lower extreme offsets with the plane of first fixed block 31 upper end to prevent lifting unit 2 to fall, realize lifting unit 2's preliminary fixed.

Referring to fig. 3, a restoring rod 5 is disposed below the first fixing structure 3, the restoring rod 5 is vertically slidable, the restoring rod 5 is provided with a handle 51 extending out of the surface of the first vertical rod 11, the upper end of the restoring rod 5 is provided with a first inclined surface 52, the lower end of the first fixing block 31 is provided with a second inclined surface 311, the first inclined surface 52 can extrude the second inclined surface 311, so as to compress the first elastic member 32, that is, the first fixing block 31 slides in a direction away from the first lifting rod 21, and further, the first fixing block 31 is separated from the first saw teeth 211.

Referring to fig. 4, the second fixing structure 4 includes a second fixing pin 41, the second fixing pin 41 is configured to be horizontally slidable, the second lifting rod 22 is provided with a plurality of fixing holes 221 corresponding to the second fixing pin 41, and the second fixing pin 41 can be inserted into the fixing holes 221 to fix the second lifting rod 22, thereby fixing two ends of the lifting portion 2. It should be noted that the distance between the fixing holes 221 is matched with the distance between the first saw teeth 211, which facilitates the height adjustment of the lifting part 2.

For a better understanding of the above-mentioned height-adjustable guardrail, the following is a specific working principle thereof: when the height of the guardrail needs to be increased, the second fixing pin 41 of the second fixing structure 4 is separated from the fixing hole 221, then the lifting part 2 is lifted upwards, the first sawtooth 211 on the first lifting rod 21 slides over the first fixing block 31 from bottom to top, the lifting part 2 is lifted to a proper height, the first fixing block 31 extends into the first sawtooth 211 under the elasticity of the first elastic part 32, the first lifting rod 21 is supported through the plane at the upper end of the first fixing block 31, then the second fixing pin 41 is inserted into the fixing hole 221, and the fixing of the lifting part 2 is completed. When the lifting part 2 needs to be lowered, the second fixing pins 41 at both ends are separated from the fixing holes 221, the restoring rod 5 is slid, the second inclined surface 311 is extruded through the first inclined surface 52, and the first fixing block 31 is separated from the first saw teeth 211, so that the lifting part 2 is lowered due to self weight.
