The invention discloses a safe heat-insulated
welding clamp, and belongs to the technical field of
welding clamps. The safe heat-insulated
welding clamp comprises a
handle, an upper pressure
handle, an upper main electric conductor, a lower
branch electric conductor, an upper protective cover and a spring, wherein the lower
branch electric conductor is installed at the front end of the
handle, thetail portion of the lower
branch electric conductor is in interference fitting with a protruding fixing point b, the two sides of the
tail portion of the upper main electric conductor are in interference fitting with protruding fixing points a, and the protruding fixing points a are connected with the protruding fixing point b through fixing plugs. A wire inlet is formed in the
tail portion of the upper main electric conductor, the upper main electric conductor is in clearance fit with a cable through a groove screw, and the cable penetrates through the handle and is in clearance fit with theinterior of the upper main electric conductor. The cable is connected with the upper main electric conductor, so that the generated heat is concentrated upon the upper portion of the welding clamp, and the handle is prevented from emitting heat too early; the surface, making contact with the lower branch electric conductor, of the handle is small, the handle is indirectly connected with the uppermain electric conductor to be away from a heating source, and the anti-scald effect is obvious; the cable penetrates through the handle to be installed in the upper main electric conductor, and convenience is brought to disassembly.
