Description

Technical Field

[0001] This utility model relates to the field of grounding wire fixing technology, and in particular to a grounding wire fixing device for welding machines. Background Technology

[0002] Existing grounding fixing devices for welding machines have fixed-size fixing components, making them difficult to adapt to grounding wires of different thicknesses. The complex structure also makes disassembly and maintenance difficult. A Chinese patent, CN202021007218.7, discloses a grounding fixing device for welding machines. This device, with its movable space within a fixed housing, allows the grounding wire to pass through a first and second through-slot. The welding machine is then placed on top of the housing, pressing down on a button. This causes the button to press down, separating a short rod to the sides. Two long rods rotate around their connecting section to a near-horizontal position, causing two sliding rods to separate. This allows a limiting block to lift a pressing block, securing the grounding wire through the misalignment of the first and second through-slots. Simply placing the welding machine on top of the device secures the grounding wire, making it convenient and practical. However, the fixing components are difficult to adjust, leading to insufficient compatibility with different grounding wire types. The complex structure also makes disassembly and maintenance difficult. Utility Model Content
