[0043] Through the above scheme: when in use, the baffle plates 32 on both sides are pulled, and under the action of the connecting plate 31, the movable plates 29 on both sides are pulled to move backwards. Since the fixed gear 28 is meshed with the tooth groove 30, the fixed gear 28 is driven to rotate during the movement of the movable plate 29. Since the fixed gear 28 is fixedly connected to the support screw rod 33, the support screw rod 33 rotates accordingly. Under the action of the thread, the screw sliders 34 on both sides are pushed to drive the support plate 36 to move upward, and the fixation is completed by inserting the fixed plug rod 35 into the fixed plug rod 35.

[0048] Secondly, when in use, the air-conditioning body 26 to be tested is placed on the supporting platform 12, and the second hydraulic cylinder 13 is started to drive the cross-shaped movable block 14 to move downward. Since the cross-shaped movable block 14 is movably pinned to the adjusting plate 15, and the adjusting plate 15 is movably pinned to the sliding block 17, under the action of the adjusting plate 15, the sliding block 17 moves along the supporting slide rod 16 toward the center of the supporting platform 12, so that the clamping block 18 clamps and fixes the front and rear sides of the air-conditioning body 26.

The third hydraulic cylinder 20 is started to pull the movable push block 21 downward, thereby moving the concave plate 22 and the convex plate 24 downward to clamp and fix the air conditioner body 26 from top to bottom.

[0050] Then, when in use, pull the baffle plates 32 on both sides, and under the action of the connecting plate 31, pull the movable plates 29 on both sides to move backwards, and since the fixed gear 28 is engaged with the tooth groove 30, the fixed gear 28 is driven to rotate during the movement of the movable plate 29, and since the fixed gear 28 is fixedly connected to the support screw rod 33, the support screw rod 33 rotates accordingly, and under the action of the thread, the screw sliders 34 on both sides are pushed to drive the support plate 36 to move upward, and the fixation is completed by inserting the fixed plug rod 35 into the fixed plug rod 35.

[0051] Finally, when in use, the driving motor 4 starts to drive the guide screw 3 to rotate, and under the action of the thread, the screw sleeve block 5 is pushed to drive the movable rack 6 to move horizontally. Since the movable rack 6 is meshed with the adjusting gear 7, under the meshing action of the gears, the adjusting gear 7 drives the fixed shaft to rotate, so that the L-shaped movable plate 8 rotates accordingly, so that the entire support platform 12 can be adjusted for the front and rear angles. The first hydraulic cylinder 10 starts to drive the connecting block 11 to move vertically.
