01228059.3 1 kinds of chucks of Chinese patent application and the counterrotating electrode holders of lever energy, it is divided into chuck and lever two parts with the whole vice body of original electrode holders, with attachment screw both are connected, angle between chuck and the lever can be regulated arbitrarily, to satisfy actual needs in 0 °-180 ° scope.In chuck sheath side, adjustment screw, spring protecting sleeve, spring, compression pin are installed successively, under the effect of spring force, compress between pin and the chuck and namely produce a shearing force, be enough to clamp welding rod; Even compress in use wearing and tearing of pin, by regulating adjustment screw to increase spring pressure, still can clamp welding rod.

Chinese patent application 97244537.4 discloses a kind of Dual-head rotating electric welding tongs, it comprises jaw (1) and handle (2), it is characterized in that jaw (1) is comprised of front jaw (3) and deutomala (4), the middle part is equipped with pinching screw (5), be hammerhead shape, have up and down two jaws (6,7), the electric conductor (8) in the middle part of deutomala (4) and the handle (2) is hinged.

Chinese patent application 201120134396.0 provides a kind of electrode holders of Universal rotary location type chuck, belongs to the welding apparatus technical field, is intended to solve existing electrode holders tip and is fixing fast knot structure, comparatively loaded down with trivial details problem in the practical application.It is that to adopt the soldering turret main body be that chuck is the soldering turret main body that is shaped with rotating shaft and attaching nut at the bottom of the tip, and the rotating shaft of tip connects the axle sleeve of soldering turret main body movingly, and chuck is the tip of cross notch at the bottom of the tip.

Summary of the invention

The welding clamp that the purpose of this invention is to provide the rotatable clamping of a kind of welding rod is realized the problem that welding rod clamping steady in a long-term is tight and soldering turret generates heat because of the contact resistance increasing with the device that rotates chucking.

Goal of the invention of the present invention realizes by following technical measures:

The principle of the invention is, in the insulation grip binding post is installed, insulation grip front end connects clamp handle, the clamp handle front end vertically connects nose plier with center line, rotary sleeve is installed in the nose plier, on the rotary sleeve outer rim cutting hole is arranged, corresponding these cutting holes of while nose plier outer rim fluting, inner in nose plier and clamp handle connecting portion, rotary sleeve is by front axle and rear link is hinged and the connecting strand nose, clamp handle is being installed pressure arm near insulation grip position, and the pressure arm rear portion connects pressure handle, and the part of pressure arm in clamp handle connects by drag-line connecting strand nose.

The invention has the beneficial effects as follows: but the rotary sleeve of multi-angle grafting welding rod is set at the nose plier place, reasonable in design, simple for structure, modern design, handling safety is nimble, clamping place Stability Analysis of Structures is solid, and the contact is reliable, also can adopt the rotation follow-up to adjust welding rod angle and gripping gesture during use, the soldering turret temperature rise is steady, acutely heating is not exempted later maintenance, significant prolongation soldering turret service life basically.
