[0028] The operator places the heat exchanger to be detected on the top of the placing plate 7, and then drives the driving gear 13 on the outer contour of the connecting shaft 12 to rotate by starting the driving motor 11 in the equipment box 10, so that the driving gear 13 drives the driven gear 14 to rotate, the driven gear 14 drives the rotating lead screw 5 to rotate, the rotating lead screw 5 drives the two lead screw blocks 51 with opposite thread directions on the outer contour of the rotating lead screw 5 to move, the lead screw blocks 51 drive the connecting rods 6 at the bottom of the lead screw blocks 51 to move, so that the interval of the two connecting rods 6 is adjusted, the connecting rods 6 at the bottom of the movable rod 61 are driven to move by the moving connecting rods 6, so that the movable rod 61 moves on the placing plate 7, and then the movable rod 61 drives the limiting frame 62 and the fixed rod 9 to move towards the heat exchanger, so that the heat exchanger is limited by the two movable rods 61 and the limiting frame 62, and displacement of the heat exchanger is avoided.

[0029] The adjusting mechanism comprises air cylinders 15 fixedly connected to the two sides of the top of the box body 1, the top end of the air cylinder 15 is limitingly and slidably connected with a telescopic rod 16, one side of the telescopic rod 16 is connected with the movable rod 61, the telescopic rod 16 is provided with a cavity 17, the inner wall of the cavity 17 is limitingly and slidably connected with a connecting rod 18, one end of the connecting rod 18 is connected with the connecting rod 6, the other end of the connecting rod 18 is fixedly connected with a baffle 20, the side of the inner wall of the cavity 17 away from the baffle 20 is boltedly connected with a rectangular limiting plate 21, the outer contour of the connecting rod 18 is slidably connected with the inner wall of the rectangular limiting plate 21, the bottom of the telescopic rod 16 is fixedly connected with a sliding rail 19, and the top end of the air cylinder 15 is fixedly connected with a sliding block 22 limitingly and slidably connected with the sliding rail 19.
