[0002] The authorization publication number is "CN206122890U". A mechanism for quickly positioning the height of a welding needle is disclosed. A height limit block is arranged in the groove. The height limit block limits the insertion depth of the welding needle into the groove. Before the welding needle is removed or installed, this mechanism cooperates with the welding device to position the height of the welding needle.
