Description

Technical area

The present invention relates to a soldering gun, in particular a soldering gun for adhering plastic.

State of the art

To make different models of electrical products and plastic products, several components are adhered to each other to make these products. The methods for adhering the components therefore form an important topic. One of these methods involves soldering, which occurs by melting the parts of one component and then adhering the component to another component with heat energy.

In addition to adhering the components, soldering can also repair cracks and breaks or holes in plastic products. Generally, an adhesive has been used in the past to repair cracks and breaks in plastic products. However, after long-term use, the original crack or break reoccurs due to the poor adhesive properties of the adhesives.

A soldering gun according to the prior art consists of a housing, a drive mechanism with a coupling, a first connecting rod, a second connecting rod, a sliding block and a heatable head, wherein one end of the coupling rotatably mounted on the housing and the other end of the coupling to a End of the first connecting rod is fixed, while another end of the first connecting rod rotatably attached to one end of the second connecting rod, another end of the connecting rod rotatably mounted on the sliding block and this sliding block is mounted on the heatable head. The drive mechanism is further provided with a spring, a slide block and a rail. Upon actuation of the clutch of this embodiment, the heatable head protrudes from the housing due to the drive mechanism for safe operation.

However, the soldering gun of the prior art has the following disadvantage.

When soldering to repair cracks and fractures in a corner of a workpiece, the user must completely invert the wrist for soldering, which is uncomfortable for the user because such a twisting of the wrist can cause muscle pain over time.
