Description

Technical Field

[0001] This utility model relates to the field of mechanical tool technology, specifically to an open-end type electric auxiliary wrench. Background Technology

[0002] Gauge rods, also known as gauge tie rods or track stabilizers, are crucial components in railway engineering used to maintain track spacing (i.e., track gauge). They connect two rails, ensuring the distance between them remains within a specified range, thereby improving track stability and safety. Because both ends of the gauge rod are connected to the rails, the end of the nut on the gauge rod located inside the rail is obstructed by the rail. During construction, disassembly and assembly can only be done manually with a wrench, making it impossible to use existing electric wrenches. This results in high labor intensity for on-site construction workers and low disassembly and assembly efficiency. Therefore, a new type of electrically driven wrench is needed to solve the aforementioned technical problems. Utility Model Content
