DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0018] Please refer to Figs. 1 to 3 The utility model provides a technical scheme:

[0019] Reference Fig. 1The main body is a fixed base 1. The upper end of the fixed base 1 has a slot, and the upper end of the slot is equipped with a telescopic column 3. The surface of the fixed base 1 is covered with conductive coating. The conductive coating can avoid the static electricity generated during the welding process as much as possible by relying on the isolation of static electricity, so as to avoid the unavoidable impact on the welding operation of the device. A pressure plate 6 is installed on the upper end of the telescopic column 3. A fixing plate is installed on the upper end of the pressure plate 6. The fixing plate and the pressure plate 6 are connected. Several small holes are left at the upper end for the assembly of some larger circuit boards. If some circuit boards exceed the space left by the fixed base 1, the protrusions designed on the surface of such circuit boards are aligned with the small holes on the surface of the fixing plate for embedding and fixing. The side of the pressure plate 6 has an embedded hole. The surface of the pressure plate 6 has a recessed layer. The telescopic block 7 is installed inside the recessed layer. The design of the telescopic block 7 can adjust the pressing block 5 connected at the front end, which facilitates the pressing effect on smaller circuit boards. The pressing block 5 is installed at the front end of the telescopic block 7. A rotating inner shaft 8 is installed on the side of the pressure plate 6.

[0020] refer to Fig. 2 The main body is a rotating inner shaft 8. An outer plate 4 is installed on the outer end of the rotating inner shaft 8, and an internal hole is provided at the corresponding position of the external plate 4. A component board 12 is placed on the internal hole for easy removal during use. The upper surface of the fixed base 1 is provided with a sliding groove hole, and a meshing block 10 is assembled inside the groove hole. A moving pad 2 is installed on the upper end of the meshing block 10. Considering that the surface of the small circuit board does not have protrusions for fixing, this type of circuit board is only suitable for flat placement. The installation of the moving pad 2 can reduce the damage when the pressing block 5 is used for fixing, and avoid the circuit board itself from breaking or tilting after pressing.

[0021] refer to Fig. 3 The main body is a fixed base 1. The fixed base 1 has an insertion port in the middle and an external protrusion 11 is installed on the upper end of the insertion port. A welding bracket 9 is installed on the upper end of the external protrusion 11. The surface of the welding bracket 9 has a slot with the same size as the solder. When welding, the solder needs to be placed on the upper end of the slot to fix the solder and maintain effective stability during the welding process. A welding end 14 is provided on the side of the fixed base 1. A fixed shell 13 is installed at the front end of the welding end 14. A welding tube 15 is connected to the front end of the welding end 14. An elastic band 16 is installed on the surface of the welding tube 15. The welding tube 15 is used for the use and connection effect of the welding device.

[0022] In actual use, first, after the device is installed, place it on a suitable operating surface. Place the small circuit board to be soldered on the top of the moving pad 2. Before this, the position of the moving pad 2 needs to be adjusted according to the size of the circuit board to ensure that the moving pad 2 is placed at both ends of the circuit board. Then, adjust the pressing blocks 5 on both sides to a suitable position using the telescopic blocks 7, preferably pressing on both sides of the circuit board. The flexibility of the bottom moving pad 2 reduces damage to the circuit board. The plane of the fixed base 1 is covered with wire coating, which has a good isolation effect against static electricity that occurs during the soldering operation. Next, place the solder along the soldering bracket 9. After aligning the circuit board, connect it to the soldering device using the soldering end 14 mounted on the side and perform the soldering operation on the circuit board. If a larger circuit board is encountered, use the protrusions on its surface to lock and fix it according to the slots on the surface of the upper fixed plate before soldering.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
