[0055] Specifically, the first fixing hole 304 is a threaded hole, and the two first fixing holes 304 are arranged on the symmetric axis in the length direction of the fixed clamping plate 3, and the first fixing hole 304 is adjacent to the corner hole 302. The first fixing hole 304 is arranged on the symmetric axis in the length direction, so that the guide rod 4 contacts the middle part of the plate assembly 2, which facilitates the plate assembly 2 to slide between the two guide rods 4, and the plate assembly 2 is evenly stressed, which reduces the shaking of the plate assembly 2 caused by uneven stress, and improves the installation speed.

[0056] Specifically, a plurality of first mounting holes 303 are provided, and the first mounting holes 303 are evenly distributed with the length direction of the fixed clamping plate 3 as the symmetry axis. The first mounting holes 303 are evenly distributed on both sides of the fixed clamping plate 3, so that the force applied by the fixed clamping plate 3 on the plate assembly 2 is more uniform, and the plate assembly 2 is prevented from being unevenly stressed, causing the internal sealing gasket to deviate, thereby affecting the sealing effect and cooling effect.

[0057] Preferably, eight first mounting holes 303 are provided. This arrangement can evenly apply preload force through the fixed clamping plate 3 and the movable clamping plate 1, so that the preload force distribution is more uniform, and a large deviation in the preload force distribution during the bolt replacement process is avoided, which affects the cooling effect.

The second mounting hole 102 is arranged corresponding to the first mounting hole 303, and the second fixing hole 103 is arranged corresponding to the first fixing hole 304. The first foot 301 is arranged at the bottom of the fixed clamping plate 3, so that the fixed clamping plate 3 can be placed horizontally on the ground, eliminating the frame guide rod above the fixed clamping plate 3, facilitating the installation of the plate assembly 2, helping to reduce the weight of the device, saving installation space, and improving the installation and disassembly efficiency; at the same time, the second mounting hole 102 and the second fixing hole 103 are arranged corresponding to the holes on the fixed clamping plate 3, facilitating the processing of the holes on the movable clamping plate 1, making the installation and disassembly process relatively simple and quick, with a simple structure, easy maintenance, and helping to reduce the use cost.

[0059] Specifically, the fixing portion 4011 is threadedly connected to the first fixing hole 304, and the clamping portion 4022 passes through the second fixing hole 103. This arrangement has a simple structure and is easy to disassemble. At the same time, there is no extension outside the fixing clamping plate 3, which reduces space occupation and helps to further reduce the installation space.

[0060] Specifically, the first bolt 501 passes through the first mounting hole 303 and the second mounting hole 102 to connect the nut 503 , and the nut 503 is adjacent to the movable clamping plate 1 .

[0061] Specifically, the length of the second bolt 502 is 1.5 times the length of the first bolt 501.
