Abstract
The utility model relates to an electric welding holder for a manual arc welder. An upper jaw and a lower jaw can be hinged through male pins; the upper jaw is connected with a handle; the lower jaw is connected with a red copper holder body; a tension spring is connected between the handle and the holder body; a tube is sheathed outside the holder body; a via hole is arranged on one end of a power cord connected with the holder body; a screw hole whose direction is vertical to the direction of the via hole is arranged on the holder body, wherein, a red copper screw bolt is provided with a cord passing hole communicated with the via hole. The cord passing hole and the via hole of the utility model can stagger and tightly jam the power cord inserted into the holes; the fixing is firm; the power cord is different to heat generation, the holder body can carry out continuous operation for a long time; the assembly and disassembly of the power cord are convenient; the work efficiency can be increased.
Description
The utility model relates to a kind of electrode holders that are used for manual metal-arc welding.
Present employed electrode holders, the connection of its power line is to open a through hole in the caliper end, and power line is inserted through hole, an attached block pressur plate on the power line, withstand pressing plate fixed power source line at through hole external application screw then, its shortcoming is that power line is fixing not firm, and is easily loosening, thereby the easy very fast heating when causing caliper work of generating heat of power line, need often cooling, and during the dismounting power line, need the sleeve pipe that caliper is outer to take off, influence operating efficiency.
The purpose of this utility model is the electrode holders that a kind of power line of design is fixed, caliper is difficult for heating and power line easy accessibility.
The technical solution of the utility model is that the caliper that has electrode holders now is partly improved.Electrode holders comprise upper jaw, lower jaw, upper jaw and lower jaw are hinged by pin, upper jaw is connected with handle, lower jaw is connected with the red copper caliper, be connected with tension spring between handle and the caliper, the caliper outer tube, an end that connects power line at caliper has through hole, also have the screw vertical on the caliper, have the threading hole that communicates with through hole on the red copper bolt wherein with the through hole direction.
In the utility model, threading hole and through hole will insert wherein the power line jam-packed that staggers, and fixed, power line is difficult for heating, but the caliper long time continuous working, and the power line easy accessibility, therefore improved work efficiency greatly.
Fig. 1 is the structural representation of the present electrode holders that use;
Fig. 2 is a structural representation of the present utility model.
Below in conjunction with description of drawings:
Upper jaw (1) is hinged by pin (3) with lower jaw (2), upper jaw (1) is connected with handle (4), lower jaw is connected with red copper caliper (5), be connected with tension spring (7) between handle (4) and the caliper (5), the outer sleeve pipe (6) that is with of caliper (5), an end that connects power line (12) at caliper has through hole (8), clamps on this and also has the screw (9) vertical with through hole (8) direction, has the threading hole (11) that communicates with through hole (8) on the red copper bolt (10) wherein.
During work, nut (13) is unclamped, make threading hole (11) and through hole (8) over against, insert power line (12), fastening nut (13) staggers through hole and threading hole, thereby the power line jam-packed is fixed then.
Claims (1)
1, a kind of electrode holders, comprise upper jaw (1), lower jaw (2), upper jaw and lower jaw are hinged by pin (3), upper jaw is connected with handle (4), lower jaw is connected with red copper caliper (5), is connected with tension spring (7) between handle and the caliper, it is characterized in that: the end that caliper connects power line (12) has through hole (8), also have the screw vertical (9) on the caliper, have the threading hole (11) that communicates with through hole on the red copper bolt (10) wherein with the through hole direction.
