The screw rod is adjusted to adapt to construction grounds of different flatness, and the support of the telescopic rod further improves the ability to prevent rollover, thereby providing a safe and effective working environment; and the feature that the ladder rods on both sides can be opened at different angles also enables it to adapt to more diverse working conditions of going up and down the ladder. The safety ladder device for construction in the above patent has the following shortcomings: it is not easy to support when it needs to be used in corners or narrow areas, resulting in poor balance, which leads to safety hazards. In view of this, the present utility model is proposed. Utility Model Content

[0007] Furthermore, the side wall of the limit block is provided with a tooth groove.

[0008] Furthermore, a sliding groove is formed on the outer wall of the second leg, and a limiting column corresponding to the sliding groove is fixedly connected to the inner wall of the casing, and the limiting column is slidably connected to the sliding groove.

[0009] Furthermore, one end of the threaded column away from the rotating block passes through the outer wall of the casing and is threadedly connected to the limiting bar.

[0010] Furthermore, the depth of the limiting groove is the same as the height of the limiting block, and the width of the limiting groove is the same as the width of the limiting block.

[0011] Furthermore, a connecting block is fixedly connected to the outer wall of the housing, a return spring is fixedly connected to the surface of the connecting block, and an end of the return spring away from the connecting block is fixedly connected to a U-shaped block.

[0012] Furthermore, the U-shaped block is slidably connected to the casing.

[0013] Furthermore, a tooth block corresponding to the side wall of the limiting block is provided on the side of the limiting strip away from the threaded column.

[0014] Compared with the prior art, the utility model provides a safety ladder for construction, which has the following beneficial effects:

[0015] 1. The safety ladder for building construction slides out along the slide groove through the limiting column by sliding the sleeve, and then rotates toward the first leg to insert the limiting block into the limiting groove. Then, the angle of the second leg is adjusted by the telescopic rod, and then the rotating block is rotated to limit the limiting block through the threaded column to drive the limiting bar to limit the limiting block, thereby increasing stability and achieving better balance when used in corners or narrow areas, reducing safety hazards.

[0016] 2. The safety ladder for building construction uses a reset spring to push the U-shaped block to limit the rotating block, so as to ensure the stability of the limit block and avoid the limit block sliding due to human body gravity during use and causing injuries to workers.

[0017] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS
