[0026] The inside of the sliding rod 53 is provided with an auxiliary mechanism 6, and the stability of the sliding rod 53 can be improved by arranging the auxiliary mechanism 6. The auxiliary mechanism 6 comprises an inclined block 61, a lead screw 62, a knob 63, a sliding plate 64, a limiting block 65 and a rubber block 66. The inclined block 61 is slidably connected to the inner wall of the sliding rod 53. The side wall of the inclined block 61 is rotatably connected to the lead screw 62. The end of the lead screw 62 away from the inclined block 61 is fixedly connected to the knob 63 penetrating through the sliding rod 53. The lead screw 62 is threadedly connected to the penetrating position of the sliding rod 53. The lead screw 62 is rotated by the knob 63.

[0028] When the end seat 2 lifts the evaporator insulation box 3, the lead screw 62 is rotated by the knob 63. The inclined block 61 is driven to move away from the knob 63 by the rotation of the lead screw 62. At this time, the inclined block 61 will press the sliding plate 64, so that the sliding plate 64 drives the limiting block 65 to move to the outside of the sliding rod 53 until the rubber block 66 tightly abuts against the inside of the limiting groove 67. At this time, the interference fit between the rubber block 66 and the limiting groove 67 can limit the sliding rod 53, improve the stability of the sliding rod 53, and then the lifting plate 52 can stably support the evaporator insulation box 3.
