[0007] As a further description of the above technical solution:

[0008] The first guide rail and the second guide rail are both steel rails, and the male end of the joint and the female end of the joint form a concave-convex dovetail groove interface, and the first guide rail and the second guide rail are assembled and fixed by a mortise and tenon structure.

[0009] As a further description of the above technical solution:

[0010] The first guide rail and the second guide rail are connected and fixed to the connecting plate by screws. Four circular holes are provided on one side surface of the connecting plate, which are corresponding to the holes inserted into the butt ends of the first guide rail and the second guide rail.

[0011] As a further description of the above technical solution:

[0012] A threaded part is provided on the end of one side surface of the screw, and the screw is sequentially sleeved with a flat washer and a spring washer, which are connected and fixed by a nut. The screw, flat washer, spring washer and nut are all provided in four groups.

[0013] The utility model has the following beneficial effects:

[0014] In the utility model, the joints of the two sections of the guide rails are made into a dovetail shape, which improves the connection strength, ensures the connection accuracy, prevents displacement and deviation from affecting the sliding of the fall arrester, effectively prevents the fall arrester from getting stuck and pausing when sliding, avoids the risk of falling from a high altitude, and allows the fall arrester to slide smoothly, which can improve work efficiency, protect the safety of life and property, prevent accidents involving fatalities, and improve overall practical performance.
