[0029] Through the technical scheme, when the cross rod 2 moves upward, the two second sliding blocks 6 slide against the outer wall of the limiting frame 13 and approach each other, when encountering the clamping groove 14, the inner wall of the clamping groove 14 abuts against the inclined surface of one side of the clamping block 10, under the extrusion of the clamping groove 14, the clamping block 10 is pushed to move to the inside of the second sliding block 6, and the first spring 9 is compressed, after the height of the cross rod 2 is adjusted, the clamping block 10 is moved into the corresponding clamping groove 14, at this time, if the cross rod 2 is pressed by external force, the two second sliding blocks 6 will move away from each other, the other side of the clamping block 10 abuts against the clamping groove 14, the clamping block 10 cannot move through the limiting of the clamping groove 14, thereby the position of the cross rod 2 is firm and cannot move downward due to pressing, when the height of the fence rod is low, the cross rod 2 needs to be moved downward to adjust the position of supporting the fence rod, at this time, the top plate 11 is pressed downward, the top plate 11 abuts against the inclined surface on the top of the clamping block 10 under the extrusion of the top plate 11, the clamping block 10 is pushed to move to the inside of the second sliding block 6, and the clamping block 10 is separated from the clamping groove 14 after moving, at this time, the cross rod 2 can be moved downward.

[0030] Specifically, the clamping assembly comprises a sliding groove 21, the sliding groove 21 is arranged in the inside of the cross rod 2, the inside of the cross rod 2 is symmetrically and slidingly connected with two second clamping blocks 22 taking the sliding groove 21 as the center, one end of the two second clamping blocks 22 extends to the inside of the sliding groove 21, the top and the bottom of the second clamping block 22 are provided with inclined surfaces, the other end of the second clamping block 22 is fixedly connected with a second spring 23, and the second spring 23 is fixedly connected with the cross rod 2.

[0032] Specifically, the inner wall of the second clamping block 22 is fixedly connected with a rotating shaft 24, and the outer wall of the rotating shaft 24 is rotatably connected with a pulley 25.

[0033] Through the technical scheme, the pulley 25 is arranged, the friction between the fence rod and the second clamping block 22 is reduced, and the position of the cross rod 2 is adjusted upward or downward.

[0034] Specifically, the outer wall of the first clamping block 17 is fixedly connected with a rubber pad 18.

[0036] In use, when the quick-mounting protective fence is fixed, the base 1 is arranged at a position on the building side where protection is needed, the fence rod is inserted from the sliding groove 21, and the outer wall of the fence rod abuts against the inclined surface on the top of the two second clamping blocks 22. Under the extrusion of the fence rod, the two second clamping blocks 22 are simultaneously moved and moved away from each other, and the two second springs 23 are compressed after the two second clamping blocks 22 are moved away from each other.

The fence rod of different sizes can be fixed, the pulley 25 is arranged to reduce the friction between the fence rod and the second clamping block 22, so as to facilitate the upward or downward adjustment of the position of the horizontal rod 2. Then the fence rod is inserted into the insertion slot 15, the knob 20 is rotated to drive the bidirectional screw rod 19 to rotate, so that the two sliding plates 16 move close to each other, and the two first clamping blocks 17 move close to each other. The two sides of the fence rod are clamped and fixed by the two first clamping blocks 17, so that the fence rod is fixed on the base 1. Thus, the fence rod of different sizes can be fixed. After the two first clamping blocks 17 clamp and fix the fence rod, the rubber pad 18 is arranged to increase the friction between the fence rod and the first clamping block 17, so that the fence rod is fixed more firmly.

Under the extrusion of the clamping groove 14, the clamping block 10 is pushed to move to the inside of the second sliding block 6, and the first spring 9 is compressed. After the height of the horizontal rod 2 is adjusted, the clamping block 10 moves into the corresponding clamping groove 14. At this time, if the horizontal rod 2 is pressed by external force, the two second sliding blocks 6 will move away from each other, and the other side of the clamping block 10 abuts against the clamping groove 14. The clamping block 10 cannot move through the limiting of the clamping groove 14, so that the position of the horizontal rod 2 is firm and will not move downward due to pressing. When the height of the fence rod is low, the horizontal rod 2 needs to be moved downward to adjust the supporting position of the fence rod. At this time, the top plate 11 is pressed downward to abut against the inclined surface on the top of the clamping block 10. Under the extrusion of the top plate 11, the clamping block 10 moves to the inside of the second sliding block 6. After the clamping block 10 moves, it is separated from the clamping groove 14. At this time, the horizontal rod 2 can be moved downward.
