Abstract
The present invention relates to a welding tool, particularly to an electrode holder. The gradual pollution of high temperature dust and sputtering melted beads can not be avoided by a traditional electrode holder which is easy to cause the bad contact of the electrode holder and a welding stick to result in arcing difficulty and unstability. The serious fervescence of the electrode holder not only wastes electric energy, but also influences work. The hinged holding type electrode holder of the present invention is characterized in that the front ends of an upper handle body and a lower handle body are provided with a cutting edge, and cutting edges are hinged in a head part of an electric welding stick and are positioned by pawls and ratchets on the tail ends of handle bodies. The hinged holding method of the present invention ensures a contact surface the electrode holder and the welding stick not to be polluted but to contact densely, and the cost of the hinged holding type electrode holder is reduced to a brand new level because the hinged holding type electrode holder does not need fabricating by using red copper or copper alloy.
Description
Technical field the present invention relates to a kind of soldering appliance, particularly relates to a kind of electrode holders.
All with red copper or copper alloy manufacturing, purpose is to wish its favorable conductive and heat radiation to the electrode holders that background technology is found everywhere.The clamp method of this kind electrode holders all is to clamp welding rod with spring force, high-temperature dust that produces when welding rod melts in actual use and the bead that splashes have been stained the clamp port of this kind electrode holders gradually, along with the prolongation soldering turret of working time and the contact condition of welding rod constantly worsen, cause starting the arc difficulty, instability, the caloric value of electrode holders constantly rises, even the welder can't be operated, and electric energy has been wasted in excessive heating.
Summary of the invention the object of the present invention is to provide a kind of many scarce limit that overcomes the clipping electrode holders of spring, and is bad as contact condition, hyperarc is unstable, stain easily and new hinged holding type electrowelding tongs that heating, clamping are tight etc.
Technical scheme of the present invention is to realize like this.These electrode holders comprise upper and lower insulating sheath that can segmentation on handle body, bearing pin, leaf spring and the upper and lower handle body of bearing pin twisting, the location ratchet of upper and lower handle body afterbody and ratchet etc., it is characterized in that upper and lower handle body front end is shaped on cutting edge, this cutting edge relies on the electric welder that the hinge of holding with a firm grip of upper and lower handle body is opened the welding rod surface when the clamping welding rod, and incision welding rod head reaches about half of diameter deeply.Simultaneously cutting with scissors tight position by the location ratchet of handle body afterbody and ratchet at this locatees automatically.Press the upper and lower handle body of location ratchet with thumb and separate under the leaf spring effect, welding rod and soldering turret break away from.
Description of drawings Fig. 1 is the structural map of the embodiment of the invention, and Fig. 2 is the A-A cutaway view of Fig. 1.Insulation sleeve 2, bearing pin 3 among the figure 1, before the lower handle, go up handle body 4, leaf spring 5, go up insulation sleeve 6, ratchet 7 behind the handle body, go up insulation sleeve 9, ratchet spring 10, lower handle and ratchet 11, lower handle cutting edge 12 behind insulation sleeve 8 before the handle body, the lower handle, go up handle body cutting edge
The specific embodiment is in Fig. 1, last handle body (3) is hinged with lower handle and ratchet (10) by bearing pin (2), one end of leaf spring (4) is fixedlyed connected with last handle body (3), one end of ratchet spring (9) is also fixedlyed connected with last handle body (3), ratchet (6) is hinged by the rear end of small clevis pin with head and last handle body (3), and each insulation sleeve is fastened on corresponding site with screw.Welding rod can place between lower handle cutting edge (11) and the last handle body cutting edge (12) at any angle, handle body (3) and lower handle and ratchet (10) are drawn close them mutually on holding with a firm grip, lower handle cutting edge (11) will cut the welding rod surface simultaneously with last handle body cutting edge (12) and cut about half of welding rod head diameter like this, simultaneously ratchet (6) under ratchet spring (9) effect and lower handle and ratchet (10) cut with scissors tight position at this and locate automatically.Press ratchet (6) with thumb handle body (3) and lower handle and ratchet (10) are separated around bearing pin (2) under leaf spring (4) effect, lower handle cutting edge (11) also separates around bearing pin (2) with last handle body cutting edge (12) simultaneously, and welding rod breaks away from soldering turret automatically.
Owing to adopt such scheme, welding current feeds in the welding rod from cutting edge incision welding rod by the handle body, no matter welding rod is placed on which position of upper and lower cutting edge or becomes what angle with upper and lower cutting edge, all because the squeezing action that is winched into of cutting edge is peeled off the dust of staining on the cutting edge and bead and cutting edge fully, thereby keep the soldering turret tong chops not stained gradually, reduce the soldering turret caloric value, prolong soldering turret service life.
Claims (1)
1, a kind of electrode holders, in forward and backward, upper and lower insulating sheath, include upper and lower can be around the location ratchet and the ratchet of handle body, bearing pin, leaf spring and the tail end thereof of bearing pin twisting, it is characterized in that: the jaw place of said electrode holders is shaped on cutting edge, this cutting edge cuts with scissors when the clamping welding rod and snaps in the bar surface incision welding rod, simultaneously, cutting with scissors tight position with the ratchet that is fixed on the lower handle afterbody at this by the location ratchet that is hinged on handle body tail end locatees automatically.
