The clamping groove 402 is arranged on the outer side of the slot 401, after protruding upwards, the upper end of the clamping groove 402 is horizontally bent towards the pressing plate 20 to form a groove which is horizontally oriented towards the direction away from the pressing plate 20, the clamping protrusion 302 is inserted into the clamping groove 402 along the horizontal direction, the upper top wall of the groove of the clamping groove 402 is abutted with the upper top wall of the clamping protrusion 302, the side end face of the clamping protrusion 302 is abutted with the inner side of the clamping groove 402, the lower bottom wall of the clamping protrusion 302 is the bottom plate face of the pressing plate 20, and the clamping protrusion 302 is abutted with the groove side platform 1012. When the middle part of the pressing plate 20 is jacked up by the evaporating pipe 2, the plate surface of the pressing plate 20 deforms and protrudes upwards, the clamping protrusions 302 at the two ends of the pressing plate 20 are limited by the clamping grooves 402 of the groove edge platform 1012, and meanwhile, the inserting posts 301 at the two ends of the pressing plate 20 are limited by the side walls of the inserting grooves 401, so that the pressing plate 20 is locked at the notch 1011 of the mounting groove 101.

As shown in fig. 4, when the pressure plate 20 receives an upward force from the evaporation tube 2, the pressure plate 20 and the groove side lands 1012 of the mounting groove 101 interact to prevent the pressure plate 20 from being lifted up by the evaporation tube 2. Wherein F1 in fig. 4 is the force applied by the card slot 402 to the card protrusion 302; f2 and F3 are forces exerted by socket 401 on socket 301; f4 is the upward jacking force applied to the platen 20 by the evaporating tube 2; when the evaporation tube 2 applies an upward jacking acting force to the pressing plate 20, the pressing plate 20 deforms under the combined action of the evaporation tube 2 and the evaporation dish 10, the middle part of the pressing plate is upwards convex, at the moment, the top of the clamping convex 302 is contacted with the inner top wall of the clamping groove 402, the clamping convex 302 has a trend of being separated from the clamping groove 402, the top wall surface of the clamping convex 302 inclines to generate a friction force with the inner wall surface of the clamping groove 402, F6 is the friction force applied by the clamping convex 302 to the clamping groove 402, and F5 is the force applied by the clamping groove 402 to the clamping convex 302. When the pressing plate 20 deforms and the middle part protrudes upwards, the side wall of the inserting column 301 is abutted against the inner side wall of the slot 401 under the influence of the deformation of the pressing plate 20, and friction force F3 and forward force F2 are generated. The downward force F experienced by the platen 20 is the combined force of F3 and F1. When the pressing plate 20 is buckled on the notch 1011 of the mounting groove 101, the F4 acts on the pressing plate 20 to generate deformation, and meanwhile, the force F2 of the inserting column 301 acting on the inserting column 301 of the pressing plate 20 is generated, and the two forces are propped against each other to generate an interlocking state, so that the deformation of the pressing plate 20 is prevented from being separated from the clamping groove 402. The friction force F3 is generated when F2 is generated, the resultant force of F3 and F1 is F, the friction force of the inserted column 301 can reduce the acting force F1 of the clamping groove 402 on the clamping convex 302, and the clamping groove 402 is prevented from being separated from or failing due to overlarge deformation. When the snap-fit is performed, the snap-fit protrusion 302 is subjected to force F5, and thus deformation is generated, and the deformation of the snap-fit groove 402 is reduced at the same amount of snap-fit.
