<p>The present invention relates to a welding rod clamp of a spot welding device. The present invention includes a first clamp including an extended part with a combination hole in a side, a first hinge part in a central part, a first storage part in an end part, a pair of first placing grooves, separated from each other, in the other side, and a second hinge part protruding from the first placing groove; a second clamp hinged with the first hinge part by including a through part in a central part, and including a second storage part in an end part, a second placing groove, facing the first placing groove, in the other side, and a cut part formed in the second placing groove to insert the second hinge part; an elastic member placed between the first and second placing grooves; a lever member including a knob part in a side, a cam part in the other side to push the second clamp to the bottom by making contact with an upper surface of the second clamp, and a cutout in an end part of the other side to be inserted into the second hinge part. According to the present invention, the simple rotation of the lever member, included in the clamp, makes the replacement of the welding rod simple and accurate, and therefore, the efficiency of the spot-welding device is increased and the productivity is improved through the improvement of workability by the replacement of the welding rod.</p> |
