The connecting ring 701 is fixedly installed on the outer side of the connecting port 703, and the clamping rod 702 passes through the connecting port 703. The staff manually rotates the clamping rods 702 on both sides to make the clamping rods 702 on both sides contact with the detection component, thereby clamping it. When the detection component needs to be taken out, the clamping rods 702 on both sides are rotated in the opposite direction again, and rotated outward to make the clamping rods 702 leave the detection component. When the connector 7 needs to be disassembled, it is directly rotated in the opposite direction to screw it out.

[0026] The air conditioner four-way reversing valve assembly detection device is provided with a fixing mechanism 5, which includes a clamping rod 501, a mounting shell 502, a clamping ball 503, a spring ring 504 and a protective cover 505. When it is necessary to maintain and repair the internal parts of the box body 2, the outer side of the side wall of the mounting shell 502 away from the clamping ball 503 is threadedly connected with the protective cover 505, the protective cover 505 is rotated and unscrewed, and the mounting shell 502 is slidably connected with the clamping rod 501, and the clamping rod 501 is pressed toward the inner side of the mounting shell 502.

The side away from the moving rod 805 is rotatably connected to the fixed rod 801 through a pin, and the second connecting rod 804 on the far right is rotatably connected to the outside of the sliding block 802. When the moving rod 805 is pulled to the left, the first connecting rod 803 and the second connecting rod 804 are stretched out, so that the moving rod 805 extends to the left. The top of the moving rod 805 is connected to a dustproof curtain 806 through a rod. When the moving rod 805 is opened, the dustproof curtain 806 is pulled open to block the box body 2. When it is opened, the moving rod 805 is directly pushed to the right, and the first connecting rod 803 and the second connecting rod 804 are retracted.
