When the threaded rod 6 works, it drives the splint 7 to move, and clamps the two splints 7 on the heat exchanger cover, thereby reinforcing the tested heat exchanger cover, and can reinforce heat exchanger covers of different specifications and widths, thereby improving the user experience.

[0026] In this embodiment, preferably, a threaded hole is opened inside the limiting seat 5, and the threaded hole is opened. The threaded rod 6 passes through the threaded hole. The threaded rod 6 uses the cooperation of the threaded hole to drive the clamping plate 7 to move more conveniently.

[0027] In this embodiment, preferably, two clamping plates 7 are provided, and a gap is left between the clamping plates 7 and the inner side surface of the limiting cavity 51 to reduce the resistance when the clamping plates 7 move.

[0028] In this embodiment, preferably, a fastening plate is provided on the side surface of the limiting seat 5 to realize the addition of the fastening plate. A screw hole is opened inside the fastening plate, and the fastening plate and the base 1 are connected by screws, and the fastening plate and the base 1 are firmly fixed by the screws.
