Further, a baffle is fixed on the upper side of the bottom plate, and the baffle is arranged on one side of the supporting plate.

The beneficial effects obtained by the utility model by adopting the structure are as follows:

Through putting the heat exchanger slab in the backup pad from the one side that sets up the baffle never, until heat exchanger slab withstands the baffle, operation roll adjustment motor makes two-way lead screw rotate with the slider adjustment to suitable position, operation electric telescopic handle stretches out and fixes heat exchanger slab centre gripping, because roll adjustment structure and clamping structure are symmetrical about backup pad middle part, and the position of baffle is also fixed, consequently add and hold back each group heat exchanger slab and all can be fixed to the coplanar, the problem that traditional heat exchanger slab welded anchor clamps can not fix the heat exchanger in the coplanar can lead to the welding time to not accurate welding has been solved.
