The clamping shell is elastically connected with the guide plate and the clamping shell through the big bolts which are sheathed with springs. Insertion openings for welding rods are arranged at the head parts of the guide plate and the clamping shell. A notch which is match with the size of the junction box is arranged at the back end of the clamping shell. A small semicircular groove is arranged at the top part of the notch. The junction box which is arranged at the back part of the guide plate is arranged in the notch. A bolt for wire connection is supported in the small semicircular groove. The utility model which is a long-life electric welding holder has the advantages of simple structure, small size, light weight and long service life.

Description

Durable electrode holder

The utility model belongs to solder set, relates in particular to a kind of manual electric arc welding weld clip.

At present, widely used electrode holder external form is like scissors, and the front portion is a duckbill metal clamp, the shell of clamp and handle are insulating materials, and with screwed jackscrew it are connected as a single entity, and bit is made by copper material, its cable connector generally is fixed in the handle, and fastening with jackscrew.This electrode holders are in welding process, and its connector lug place can produce contact resistance owing to adopt jackscrew to fix after the energising, makes handgrip produce heat, and operator's length service time can feel hot, and jaw easily produces spark phenomenon, and service life is short.Because handle is short and small, the loading and unloading welding rod is also required great effort in addition.For addressing the above problem, I have done number of research projects to this, and two patents of ZL98209923.1, ZL00211432.1 have been applied for regard to it, a kind of novel durable electrode holder is disclosed, though it is big that this electrode holder has overcome clamp-type electrode holders volume, problems such as the easy oxidation of jaw, but also exist certain weak point, structure also compares and imitates complexity.

The purpose of this utility model provides that a kind of structure is simpler, and volume is little, and is in light weight, the durable electrode holder of long service life.

The utility model is that it of realizing like this is by shell, be located at the guide plate of shell front portion and folder shell and be located at the terminal box of guide plate back, cable is formed, cable is twisted solid rear portion at guide plate by terminal box with connection bolt, it is characterized in that shell and guide plate are passed through king-bolt, stove bolt is twisted solid, the folder shell is connected guide plate by the king-bolt elasticity that is with spring and on the shell, head at guide plate and folder shell has the welding rod socket, the rear end of folder shell has the notch that is complementary with the terminal box size, open a small half of round recessed at the notch top, the terminal box that is located at the guide plate rear portion places in the notch, and connection bolt withstands in the small semicircle groove.

Compared with prior art, the simpler compactness of the utility model structure, weight is also light, the small semicircle groove that notch upper end, clamping plate back is opened connects by elasticity, just in time the head with the terminal box bolt withstands, and has prevented the loosening of weld clip body effectively, the service life of having improved electrode holder.

The utility model is described in further detail below in conjunction with accompanying drawing.

Accompanying drawing 1 is a structural representation of the present utility model.

Referring to accompanying drawing 1, the utility model by shell 1, be located at the guide plate 2 of shell 1 front portion and folder shell 3 and the terminal box 6, the cable 9 that are located at guide plate 2 back formed, cable 9 is twisted solid rear portion at guide plate 2 by terminal box 6 usefulness connection bolts 7,8, it is characterized in that twisting shell 1 and guide plate 2 solid by king-bolt 4, stove bolt 5, folder shell 3 is connected guide plate 2 by king-bolt 4 elasticity that are with spring 10 and on the shell 1, because each parts all adopts to twist and is solidly connected, make electrode holder form a firm integral body; For making things convenient for the loading and unloading of welding rod, the utility model has welding rod socket 11 at the head of guide plate 2 and folder shell 3.Main points of the present utility model also have the notch that is complementary with the terminal box size in the rear portion at folder shell 3 again, open a small half of round recessed at the notch top, the terminal box 6 that is located at guide plate 2 rear portions so just places in the notch, and connects by elasticity, and connection bolt 8 withstands in the small semicircle groove.Prevent that not only the weld clip body is loosening, the electrode holder line contact resistance of connection jaws is diminished, be not prone to spark phenomenon, thereby reduced the generation of heat, even long-time the use, handle can be not hot yet, the simpler compactness of its structure, weight is also light, has improved service life effectively.

The utility model is applicable to various manual welding operations.
