[0008] Preferably, a plurality of latch sockets are equidistantly arranged on the height adjustment rod.

[0009] Preferably, the bearing is slidably sleeved on the height adjustment rod body and can be fixed by a latch connection.

[0010] Preferably, at least three groups of the oblique arm adjustment mechanisms are provided, and the connection between the oblique arm adjustment mechanisms and the bearings can be axially adjusted by 0-30° in the vertical direction, and any group of the oblique arm adjustment mechanisms is hinged to its telescopic oblique arm.

[0011] Preferably, the telescopic oblique arm is a telescopic sleeve rod structure.

[0012] The utility model has the following beneficial effects:

[0013] (1) The utility model solves the disadvantages of requiring special installation of safety belt hanging points for high-altitude operations, which is costly and cannot achieve full coverage;

[0014] (2) The utility model adopts a structural design and can be disassembled and moved, achieving the effect of reuse;

[0015] (3) The utility model is height-adjustable and is suitable for high-altitude operations at different heights. BRIEF DESCRIPTION OF THE DRAWINGS
