Cranks 14 are movably connected to both the left and right sides of the threaded sleeves 13 through pins. One side of the crank 14 away from the threaded sleeve 13 is movably connected to the top of the heat exchange plate 6 through a pin. A baffle 15 is fixedly connected to the top of the heat exchange plate 6. The baffle 15 is located on the right side of the crank 14.

The threaded sleeve 13 is sleeved on the surface of the guide bar 16. The guide bar 16 is slidably connected to the threaded sleeve 13.
