The invention discloses a non-standard screw assembling tool. The non-standard screw assembling tool comprises a sleeve component, a non-standard bit, a transmission component and a handle component. The sleeve part is provided with a sleeve main body and a sleeve rotating shaft which is rotatably arranged on the sleeve main body. And the non-standard bit is fixed on the sleeve rotating shaft. And the transmission part is provided with a driven gear and a driving gear which is orthogonally meshed with the driven gear. And the driven gear is fixedly connected with the sleeve rotating shaft. The handle part is provided with a handle operating rod and a connecting sleeve. And the handle operating rod is fixedly connected with the driving gear through the connecting sleeve. The non-standard screw assembling tool has the beneficial effects that the non-standard screw assembling tool is small in overall height and large in length, the torque direction is changed through gear meshing, and operation on non-standard screws with limited operation space can be achieved.

This invention discloses a lifeline system for omnidirectional movement without removing the safety harness hook. The system includes a hook assembly, an entrance / exit node assembly, a connecting node assembly, a turning node assembly, a T-junction node assembly, a cross-junction node assembly, and a wire rope assembly. Each node assembly is arranged according to the lifeline's direction, and adjacent node assemblies are connected via the wire rope assembly. The entrance / exit node assembly is used for the hook assembly to enter and exit; the connecting node assembly is used for connecting the wire rope assemblies; and the turning, T-junction, and cross-junction node assemblies are used for omnidirectional movement of the hook assembly. This system overcomes the shortcomings of traditional high-altitude work safety protection, solving the problem of omnidirectional movement without removing the safety harness hook. It allows construction workers to work normally and move omnidirectionally even under the restriction that they cannot remove the safety harness hook themselves, effectively eliminating the risk of falls from heights caused by worker inertia or a sense of complacency.
