[0007] By adopting the above technical solution, by arranging clamp one, clamp two, outer cross tube, inner cross tube, locking screws, fixing screws and nuts, the cross section can be extended and the cross section can be conveniently adjusted up and down on the guardrail; by arranging a storage tube, a rotating rod, a through groove, a warning cloth, a positioning screw and a positioning groove, warning words can be added to the positioning groove and the device can be used directly without hanging an additional warning sign.

[0008] The utility model is further configured as follows: a slide groove is provided on one side of the outer transverse tube, and the interior of the slide groove is slidably connected with the inner transverse tube.

[0009] By adopting the above technical solution, the inner cross pipe can slide easily through the setting of the slide groove.

[0010] The utility model is further configured as follows: one end of the inner transverse tube is fixedly connected to a limiting block, the surface of the limiting block is slidably connected to the inside of the outer transverse tube, and the length and width of the limiting block are greater than the length and width of the slide groove.

[0011] By adopting the above technical solution, the inner cross tube is prevented from being completely separated from the outer cross tube by setting the limit block.

[0012] The utility model is further configured as follows: the interior of the storage tube is rotatably connected to the rotating rod via two rotating shafts.

[0013] By adopting the above technical solution, the rotating shaft is arranged so that the rotating shaft is used as a shaft that bears both bending moment and torque during rotation work.

[0014] The utility model is further configured as follows: one end of the rotating rod penetrates to the outside of the storage tube, and one side of the storage tube is provided with a rotating handle fixedly connected to the rotating rod.

[0015] By adopting the above technical solution and arranging the handle, it is convenient for the user to rotate the handle.

[0016] The utility model is further configured as follows: a counterweight block is fixedly connected to one side of the warning cloth, and the length and width of the counterweight block are both greater than the length and width of the through slot.

[0017] By adopting the above technical solution, through the setting of the counterweight block, firstly, the weight of the warning cloth is increased, and secondly, the warning cloth can be prevented from being completely received into the storage tube.

[0018] In summary, the utility model has the following beneficial effects:

[0019] 1. The utility model arranges a slidable inner transverse tube inside the outer transverse tube, and locks the inner transverse tube by arranging a locking screw, so that the transverse tube can be extended horizontally, which is convenient for adapting to guardrails of different lengths;

[0020] 2. The utility model can fix the crossbar on the leftmost and rightmost railings of the guardrail by fixing the clamp 1 at one end of the inner crossbar and the outer crossbar, and using the clamp 2, fixing screws and nuts, and locking and loosening the clamp 1 and the clamp 2 by fixing screws and nuts so that the clamp 1 and the clamp 2 can be slid up and down on the left and right side railings of the guardrail;

[0021] 3. The utility model provides a storage tube, and a rotating rod with a warning cloth wrapped inside the storage tube. The warning cloth can be retracted and released by rotating the rotating rod, and warning words can be sprayed on the warning cloth. Therefore, when using an elevator guardrail with the horizontal tube, there is no need to hang an additional warning sign. BRIEF DESCRIPTION OF THE DRAWINGS
