For achieving the above object, the technical solution of the utility model is as follows:
Electric welding pen of the present utility model comprises: an insulating body, inside have the cavity of a hollow, and cavity one end has stannum export; One piston is inserted in the cavity by the cavity other end, cooperates with cavity airtight; One group of heater circuit is located at insulating body inside, and it comprises: a resistance and a heating wire of connecting with resistance; One attaching plug is connected with heating wire; It is characterized in that: described cavity successively decreases along the stannum export direction near the internal diameter of stannum export one end, is cone-shaped.
Described cavity is an arc near stannum export one end, and its radian is 30 degree～60 degree; Described stannum export diameter is 0.9 millimeter～1.1 millimeters; Described insulating body successively decreases along the stannum export direction near the external diameter of stannum export one end, is cone-shaped; Described insulating body is an arc near stannum export one end, and its radian is 30 degree～60 degree; Described insulating body outside is made by the insulation heat-barrier material; Described cavity end is made by the metal heat-conducting material; Described piston is a T shape piston; Described resistance is an adjustable resistance; Finger assurance place of the described insulating body outside has the groove of an arc; Described heating wire ring is located at the insulating body cavity near on the inwall of stannum export one end.
The utility model has the advantages that:
1. the user can regulate the soldering tin amount size, even also go up tin easily for the extremely intensive chip of pin by promoting piston;
2. insulating body is that arc and internal diameter are tiny near the cavity at stannum export place, thereby can control soldering tin amount easily, can fully use scolding tin, economical with materials;
3. tiny stannum export can reduce the thick solder horn of tradition is scalded the people because of accident after heating probability when welding, compare safety, and produces the gas after a small amount of scolding tin burning, relatively environmental protection.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done detailed description further:
As shown in Figure 1, electric welding pen of the present utility model is made up of body 1, T shape piston 2 and heater circuit, and heater circuit is made of adjustable resistance 3, heating wire 4 and attaching plug 5.
Body 1, its outside is made by the insulation heat-barrier material, and as high temperature silicon sleeve pipe and silicone insulation sleeve pipe, inside has cavity 11, one ends of a hollow to have stannum export 12, and cavity 11 ends are made by the metal heat-conducting material, as red copper; Finger assurance place of body 1 outside has the groove 13 of an arc, the grasping of being convenient to point; T shape piston 2 is made by the insulation high temperature resistant heat insulation material, as heat insulation silicon material and silicone insulation material, is inserted in the cavity 11, with 11 airtight cooperations of cavity; Adjustable resistance 3 is positioned at the outside of body 1, is used for regulating heating-up temperature; Heating wire 4 is connected with adjustable resistance 3, is wrapped on the outer wall of cavity 11 ends; Attaching plug 5 one ends are connected with adjustable resistance 2, and the other end connects external power supply, and the operating voltage of electric welding pen is provided.
Wherein, cavity 11 tops are long tubular, can place solder stick (not drawing among the figure) in it, and the bottom internal diameter successively decreases along stannum export 12 directions, and is curved cone-shaped, and its radian is 45 degree; Body 1 successively decreases along stannum export 2 directions near the external diameter of stannum export 12 1 ends, and is curved cone-shaped, and its radian is 45 degree; Stannum export 12 diameters are 1 millimeter, the tiny intensive welding thing of convenient welding, for example, when distance is 1 millimeter between chip pin, traditional electric iron is when welding, and soldering tin amount is difficult to control, is easy to take place to connect the situation of weldering and rosin joint, and electric welding pen of the present utility model utilizes superfine little stannum export 12, can be at an easy rate to its welding.
Electric welding pen of the present utility model is when carrying out the extremely intensive chip of welding pin, regulate the temperature that scolding tin need heat by adjustable resistance 3, by promoting the effect of airtight pressure in T shape piston 2 and the cavity 11, shift scolding tin the end of cavity 11 onto near stannum export 12, heating makes its fusing, then the liquid scolding tin of fusing is released cavity 11, weld, consumption can arbitrarily be adjusted with the dynamics of releasing.In addition,, make and heating and do not promoting under the situation of T shape piston 2, also do not have molten tin and drop, save scolder because an end of cavity 11 close stannum exports 12 is an arc and tiny.
Referring to Fig. 2, it is depicted as the electric welding heater circuit schematic diagram of another embodiment of the utility model.Circuit as the electric welding pen is composed in series successively by power supply V, heating wire R1 and adjustable resistance R2.Wherein, power supply V is used to provide the operating voltage of electric welding pen; Heating wire R1 is used for heating solder stick (among the figure for drawing) and makes its fusing; Adjustable resistance R2 is used for regulating the operating current of entire circuit, and then control heating wire R1 heating-up temperature.
