The connecting portion 511 can be respectively connected and fixed to the first gear 411, the second gear 412, and the third gear 413 of the gearshift portion 41, so that the adjustable ironing board 5 has three different angular positional relationships with respect to the fixed ironing board 4. When the connecting portion 511 and the shift portion 41 are in the first gear 411, the lower heat conduction block 52 has an angle of 35 ° with respect to the fixed ironing board 4, when the connecting portion 511 and the shift portion 41 are in the second gear 412, the lower heat conduction block 52 has an angle of 20 ° with respect to the fixed ironing board 4, and when the connecting portion 511 and the shift portion 41 are in the third gear 413, the lower heat conduction block 52 has an angle of 5 ° with respect to the fixed ironing board 4.
The outer layers of the first welding part 7 and the second welding part 71 are provided with teflon (polytetrafluoroethylene) coatings. The first welding portion 7 and the second welding portion 71 are respectively connected and fixed to the fixed ironing board 4 and the lower heat-conducting block 52 of the adjustable ironing board 5, and the first welding portion 7 and the second welding portion 71 are respectively connected and fixed to the fixed ironing board 4 and the lower heat-conducting block 52 through fixing screws 8.
The ironing board main body 2 includes a deformation portion 21 and an extension portion 22 extending along an end of the deformation portion 21, the extension portion 22 having a notch 23 that accommodates part of the fixed ironing board 4, the adjustable ironing board 5, and the fixing bolt 6.

One side of the temperature control main body 1 is provided with a temperature display 11, a constant temperature regulating knob 12 for controlling temperature and a constant temperature indicator light 13. The outer surface of the handle 3 is provided with a pattern 31 for increasing friction.
In the using process, firstly, the specifications of the first welding part 7 and the second welding part 71 are determined according to the outer diameter of the pipeline, then the first welding part 7 and the second welding part 71 are respectively fixed on the fixed ironing board 4 and the lower heat conduction block 52 of the adjustable ironing board 5, then the power supply is switched on, the temperature is controlled by observing the temperature display 11 and rotating the constant temperature adjusting knob 12, then the ironing board main body 2 is slowly heated in an electric heating mode, the heat is transferred to the adjustable ironing board 5 from the fixed ironing board 4, when the constant temperature indicator lamp 13 is turned on or the constant temperature indicator lamp 13 is changed from a red lamp to a green lamp, the temperature of the constant temperature indicator lamp 13 is indicated to reach a set value, and the pipeline can be subjected to hot melting connection.
In the use process, the ironing board main body 2 can protect the part of the fixed ironing board 4, the adjustable ironing board 5 and the fixing bolt 6 which are positioned in the gap 23, and the damage caused by collision is prevented. Because can debug and scald board 5 not directly be connected with ironing board main part 2, consequently there is the inhomogeneous problem of temperature that leads to of temperature conduction slower, and ironing board main part 2 is close to the both sides that can debug and scalds board 5, can prevent that can debug and scald board 5 from the too big problem of temperature fluctuation appearing in the in-process of hot melt pipeline, plays the constant temperature effect to can debug and scald board 5.
Particularly, in the process of pipeline maintenance, the pipeline on one side of the welding machine is lifted, the pipeline to be hot-melted corresponds to the first welding part 7 and the second welding part 71 respectively, and then hot melting is started, and because the first welding part 7 and the second welding part 71 are not in the same axis and are staggered with each other, hot melting connection can be carried out without bending the pipeline greatly. Compared with a traditional hot melting machine with a hot melting die head positioned on the same axis, the welding machine disclosed by the invention can adapt to a more complex construction environment, and aiming at the condition that the pipeline needs to be bent greatly to damage the wall surface or the ground in the pipeline maintenance process, the hot melting connection of the pipeline can be realized more conveniently through the construction of the welding machine without bending the pipeline greatly, so that the large-area damage to the wall surface or the ground is avoided, the maintenance cost is reduced, and the maintenance quality is improved.
In the process of lifting the pipeline on one side, because the upper heat conduction block 51 and the lower heat conduction block 52 of the debuggable ironing plate 5 have an included angle of 120 degrees, and the lower heat conduction block 52 has an included angle of 35 degrees relative to the fixed ironing plate 4, when the welding machine is used for hot melting with the pipeline on one side, the pipeline on the other side can be subjected to hot melting without being lifted to a position flush with the first welding part 7 or the second welding part 71, and compared with the traditional hot melting mode, the welding machine has a lower amplitude of lifting the pipeline. If the connection angle is slightly deviated, the angle between the adjustable ironing board 5 and the fixed ironing board 4 can be adjusted by adjusting the positions of the connection portion 511 and the shift portion 41.
Referring to fig. 8 and 9, in a second embodiment of the present invention, the lower end of the adjustable ironing board 5 is further provided with a heat insulating sleeve 8 for easy installation or disassembly, the inner wall of the heat insulating sleeve 8 is provided with a limiting protrusion 81, the outer surface of the lower heat conducting block 52 of the adjustable ironing board 5 is provided with a limiting groove 521 corresponding to the limiting protrusion 81, and the lower heat conducting block 52 and the heat insulating sleeve 8 are detachably fastened and connected.
In the process of debugging the angle between the ironing board 5 and the fixed ironing board 4 in need of adjustment, especially under the condition that the temperature of the ironing board main body 2 is still high, the heat insulating sleeve 8 is fixed outside the lower heat conducting block 52, the heat insulating sleeve 8 can isolate the high temperature generated by the ironing board main body 2, the safety of a user is ensured, and the angle of the debuggeable ironing board 5 can be adjusted more conveniently and efficiently through the heat insulating sleeve 8.
According to the invention, the first welding part and the second welding part which are staggered with each other are adopted, so that the welding machine can adapt to a complex construction environment and a narrow construction space, and the construction efficiency and the welding quality are improved.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
