The right end of the movable rod is movably connected to a sleeve through a connecting seat. A clamping column is fixedly connected to the surface of the sleeve. The utility model solves the problem that the existing geomembrane welding machine does not have a handrail for conveniently adjusting the position of the geomembrane welding machine by setting the movable rod, the sleeve, the clamping column, the clamping sleeve and the telescopic rod, so that the operator needs to hold the body of the machine to adjust when adjusting.

[0004] As an important civil engineering construction equipment, a geomembrane welding machine is mainly used for the welding work of geomembranes to improve construction efficiency and quality. Although the above patent has a handrail for conveniently adjusting the position of the geomembrane welding machine, the above handrail occupies a relatively large space. When the handrail is not needed, it is not convenient to fold and store, increasing the occupied space and having a certain impact on the use of the handrail.

[0005] Therefore, a geomembrane welding machine with a folding handle is proposed. Content of the Utility Model

[0006] In view of this, the utility model provides a geomembrane welding machine with a folding handle to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.
