[0020] By fixing a fixed cylinder 2 on the surface of the tank body 1, it is convenient to use the fixed rod 5 to drive the movable sealing plug 4 to be pulled and moved in the inner cavity of the fixed cylinder 2, so that the environmentally friendly paint inside the tank body 1 flows forward along the fixed cylinder 2, and then communicates with the discharge pipe 3 through the guide cavity 7, and directly discharges the environmentally friendly paint inside the tank body 1 into the sampling tube below the discharge pipe 3, so as to avoid opening the tank body 1, causing the outside air to contact with the environmentally friendly paint inside the tank body 1 and affect the processing quality of the environmentally friendly paint. Through the setting of the guide cavity 7, the guide cavity 7 can be connected with the discharge pipe 3 by controlling the rotation angle of the fixed rod 5, so as to accurately control the outflow of the environmentally friendly paint. At the same time, a sealing cover 13 is provided at the bottom of the discharge pipe 3, which can isolate the outside air from entering the fixed cylinder 2, so as to realize sampling of the interior without opening the tank body 1.

[0021] A traction spring 8 is wound around the surface of the fixing rod 5, the front side of the traction spring 8 is fixed to the surface of the fixing plate 6, and the other side of the traction spring 8 is fixed to the surface of the fixing cylinder 2. Through the setting of the traction spring 8, the tension of the traction spring 8 is utilized to drive the fixing plate 6 to move backward, so that the fixing rod 5 and the movable sealing plug 4 are at the rear end in the inner cavity of the fixing cylinder 2, thereby sealing the environmentally friendly paint inside the tank body 1.

[0022] A limiting ring 9 is fixed to the surface of the fixing rod 5. The limiting ring 9 is located inside the traction spring 8. The limiting ring 9 can fit with the front side of the fixing tube 2. Through the setting of the limiting ring 9, the fixing rod 5 can be moved backward under the traction of the traction spring 8, ensuring that the movable sealing plug 4 is at the rear end in the inner cavity of the fixing tube 2, and the environmentally friendly paint inside the tank body 1 is isolated as much as possible from the outside of the fixing tube 2.

[0023] A fixed block is fixed on the front of the fixed plate 6, and a pull ring 10 is movably provided on the fixed block.

[0024] A marking arrow 11 is provided on the front of the fixed plate 6, and the marking arrow 11 is consistent with the position of the guide cavity 7 passing through the side of the movable sealing plug 4. By setting the marking arrow 11, the position of the guide cavity 7 can be controlled in real time, so as to facilitate the control of the environmentally friendly coating inside the tank body 1 to flow out of the discharge pipe 3.

[0025] A sealing ring 12 is sleeved on the surface of the fixing rod 5, and the sealing ring 12 is embedded in the interior of the fixing tube 2. The setting of the sealing ring 12 facilitates the sealing of the fixing tube 2 to prevent the fixing rod 5 from moving back and forth in the inner cavity of the fixing tube 2, causing the flow of gas inside the fixing tube 2 to contact with the local environmentally friendly coating and affect the quality of the sample.

[0027] When in use, place the sampling tube under the discharge tube 3, remove the cover 13, and pull the pull ring 10 at the same time. Use the pull ring 10 to pull the fixed plate 6 and the fixed rod 5 outward, and the fixed rod 5 drives the movable sealing plug 4 to move in the inner cavity of the fixed cylinder 2. When the movable sealing plug 4 is aligned with the front section of the inner cavity of the fixed cylinder 2, turn the pull ring 10 to rotate the fixed rod 5 and the movable sealing plug 4, so that the guide cavity 7 is connected with the discharge tube 3, and then the environmentally friendly paint flowing out of the tank body 1 along the fixed cylinder 2 is discharged from the guide cavity 7. The liquid in the flow cavity 7 and the discharge pipe 3 flows into the sampling tube. After the sampling is completed, the pull ring 10 is loosened, and the fixed rod 5 and the movable sealing plug 4 move backward under the traction of the traction spring 8. At this time, the flow guide cavity 7 and the discharge pipe 3 are offset and blocked. At the same time, the limit ring 9 contacts the front of the fixed cylinder 2, restricting the movable sealing plug 4 from continuing to move backward, so that the movable sealing plug 4 is at the connection point between the fixed cylinder 2 and the tank body 1, preventing the environmentally friendly paint inside the tank body 1 from penetrating outward, and then the cover 13 is covered on the bottom of the discharge pipe 3.
