when the plate body 1 needs to be disassembled, only the fixture block 4 at the opening at the top end of the slide way 6 needs to be pressed at the moment, so that after the fixture block 4 slides into the slide way 3, the gas in the slide way 6 can be pressed into the slide way 6, the first piston 7 slides and pulls the other fixture block 4 to retract into the clamp groove through the pull rope 9, the aim of disassembling the plate body 1 can be fulfilled only by pressing one fixture block 4, and the plate body 1 is more convenient to disassemble; the copper base 2 can effectively conduct heat emitted by the plate body 1, and gas in the slide 6 can expand under heating, and the clamping groove at the opening at the top end of the slide 6 is acted by the limiting rope 15, so that the gas gradually expanding in the slide 6 can push the first piston 7 and the second piston 11 to slide until the gas guide groove 12 on the second piston 11 is aligned with and communicated with the gas outlet hole 13, and at the moment, high-pressure gas in the sliding cavity 10 flows into the sliding groove 3 and is sprayed out from the gas spraying groove 14, so that the effect of quickly radiating the surface of the plate body 1 can be achieved, dust and impurities on the surface of the plate body can be cleaned, the structure can radiate heat by utilizing the heat generated by the plate body 1, a driving device is not needed to radiate the heat, the energy is saved, and only when the heat of the plate body 1 is high, the gas spraying assembly can be driven to work, so that the work of the gas spraying assembly can be automatically carried out according to the heating condition of the plate body 1; when the second piston 11 moves to the drum membrane 16, the drum membrane 16 can limit the sliding of the second piston 11, so that the resistance of the second piston 11 during movement is increased, the air pressure in the sliding cavity 10 at the bottom end of the second piston 11 is increased to a certain extent and then is ejected, and the air-jet heat dissipation effect on the surface of the plate body 1 is improved; when the second piston 11 extrudes the tympanic membrane 16, the lubricating oil 18 in the second piston can be extruded out, and then the lubricating oil 18 can play a role of lubricating when flowing down along the side wall of the sliding cavity 10, so that the condition that the second piston 11 is abraded after repeated movement is reduced; when the piston 11 slides back and forth in the sliding cavity 10, a part of the lubricating oil 18 flows downstream to the concave part 19 and is collected, the provided conveying strip 20 can convey the lubricating oil 18 to the concave pit, when the drum membrane 16 is extruded, the drum membrane 16 can drive the pressure rod 21 to extrude the end part of the conveying strip 20 on one side and extrude the lubricating oil 18 absorbed in the drum membrane, so that the effect of recycling the lubricating oil 18 is achieved; when the first piston 7 moves to a position close to the concave part 19, the elastic strip 22 can drive the coating blocks 23 to move to the concave part 19 and transmit the lubricating oil 18 to each coating block 23, so that the lubricating oil 18 can be coated on the side wall of the slide 6 by the coating blocks 23 when the subsequent first piston 7 is reset, a lubricating effect can be achieved on the slide 6, and the condition that the first piston 7 is abraded after reciprocating motion is reduced; when the air injection groove 14 injects air, the corrugated pipe 25 can be driven to gradually open, and meanwhile, a part of air is injected from the nozzle 27 at the supporting plate 26, so that the effect of air injection treatment on the plate body 1 while the nozzle 27 moves along the plate body 1 is realized, and the heat dissipation effect is more direct and efficient; when the corrugated pipe 25 at the air injection groove 14 is opened, the supporting plate 26 at the end part can attract the supporting plate 26 on the other corrugated pipe 25, so that the two corrugated pipes 25 can be opened and contracted at the same time, and air injection and air suction are carried out through the nozzle 27 in the process that the two corrugated pipes 25 are stretched back and forth, so that the heat dissipation area and the heat dissipation effect at the surface of the plate body 1 are enlarged; bellows 25 can drive the brush hair and scrape the brush to plate body 1 surface at the in-process of extension to can scrape the dust impurity on its surface, and dash down the dust under the impact of nozzle 27 department air current, improve the cleanliness on plate body 1 surface, improve plate body 1's life and radiating effect.
