The feeding frame 2 is provided at the lower side of the H-shaped water pipe 1, and the lower front side of the feeding frame 2 is connected with two left and right droppers 3, the rear side of the H-shaped water pipe 1 is connected with the first guide sleeve 4, the lower side of the first guide sleeve 4 is connected with a threaded rod 5, the front side of the threaded rod 5 is rotatably connected with a stopper 6, and the stopper 6 cooperates with the feeding frame 2, the lower side of the H-shaped water pipe 1 is provided with a moving component 7, and the H-shaped water pipe 1 is provided with a clamping component 8.

[0039] When the water supply pipe needs to be connected in the middle, the moving component 7 can be used to easily push the device to a suitable position. After the device moves to a suitable position, the moving component 7 is no longer controlled, and then the clamping component 8 is controlled to open, and then the ends of the water pipe to be connected are respectively sleeved on the two ends of the H-shaped water pipe 1, and then the clamping component 8 is no longer controlled, and the clamping component 8 will fix the water pipe to be connected, thereby realizing the middle connection of the water supply pipe; when it is necessary to sample the substance in the water supply pipe, the threaded rod 5 can be controlled to rotate, and then the first guide sleeve 4 will be used to The threaded rod 5 moves backward, thereby driving the stopper 6 to move backward, so that the stopper 6 no longer blocks the bottom of the H-shaped water pipe 1, and the material in the H-shaped water pipe 1 will flow into the discharge frame 2 and enter the dropper 3. Then, the test tube can be placed under the dropper 3, and then the dropper 3 is squeezed by hand, so that the material in the dropper 3 drips into the test tube, thereby completing the sampling of the material in the water pipe. After the sampling is completed, the threaded rod 5 is controlled to rotate in the opposite direction, so that the stopper 6 moves forward and resets to block the bottom of the H-shaped water pipe 1 again.

[0040] The moving assembly 7 includes a special-shaped rod 71, a cylinder 72, a circular plate 73, a first spring 74 and a wheel 75.

[0041] When the middle connection of the water supply pipe is required, the H-shaped water pipe 1 is pushed, and the device can be easily pushed by the rolling of the wheel 75. At the same time, the first spring 74 can effectively buffer the vibration generated by the device during the movement. When the device is moved to the appropriate position, the H-shaped water pipe 1 is no longer pushed, and then the middle connection of the water supply pipe of the device can be used.

[0042] The clamping assembly 8 includes a second guide sleeve 81, a vertical rod 82, a second spring 83 and a clamping plate 84. The upper, lower, front and back sides of the H-shaped water pipe 1 are symmetrically connected to the second guide sleeve 81. The second guide sleeve 81 is slidably connected to the vertical rod 82. The second spring 83 is connected between the vertical rod 82 and the adjacent second guide sleeve 81. The vertical rod 82 is connected to the clamping plate 84.

[0043] When the middle connection of the water supply pipe is required, the clamping plate 84 is controlled to move outward, so that the vertical rod 82 moves outward, and the second spring 83 is compressed. Then, the ends of the water pipe to be connected can be respectively sleeved on the two ends of the H-shaped water pipe 1. Then, the clamping plate 84 is no longer controlled, and the second spring 83 rebounds to drive the vertical rod 82 and the clamping plate 84 to move inward, thereby fixing the water pipe to be connected, thereby realizing the middle connection of the water supply pipe.

The lower inner side of the front cylinder 72 is connected to the L-shaped rod 91, the rear side of the L-shaped rod 91 is slidably connected to the sliding cylinder 92, the rear side of the sliding cylinder 92 is rotatably connected to the placement rod 93, the first torsion spring 94 is connected between the placement rod 93 and the adjacent sliding cylinder 92, the upper rear side of the front cylinder 72 is connected to the arc sleeve 95, the arc sleeve 95 can be retracted, the arc sleeve 95 is slidably connected to the arc slider 96, the lower side of the placement rod 93 is connected to the first gear 97, and the front cylinders 72 are connected with a gear rack 98, which cooperates with the first gear 97.

[0046] When it is necessary to sample the substance in the water pipe, the arc-shaped slider 96 can be controlled to slide open, and the test tube can be placed on the placement rod 93. Then, the arc-shaped sleeve 95 can be controlled to extend and retract, so that the arc-shaped sleeve 95 contacts the port of the test tube. Then, the arc-shaped slider 96 can be controlled to rotate and close, so that the test tube can be fixed, thereby reducing the burden of manually fixing the test tube. When the sampling of the substance in the water pipe is completed, the placement rod 93 is controlled to move forward, so that the test tube with the sample collected can move forward, so that the arc-shaped slider 96, the sliding cylinder 92 and the first gear 97 are moved to the front side. The front side moves and the arc sleeve 95 is compressed. At this time, the first gear 97 will cooperate with the tooth rack 98, thereby causing the placement rod 93 to rotate, and the first torsion spring 94 will be deformed, so that the sample in the test tube can be shaken evenly, and then the arc slider 96 can be controlled to slide open, and then the test tube can be taken out. Then, the placement rod 93 is no longer controlled, and the first torsion spring 94 recovers and drives the placement rod 93 to rotate in the opposite direction and reset. At the same time, because the first gear 97 will cooperate with the tooth rack 98, it drives the first gear 97, the placement rod 93 and the sliding cylinder 92 to move backward and reset.

[0047] It also includes an extrusion component 10, which includes a slide rail 101, a movable sleeve 102, a U-shaped sleeve 103, an extrusion rod 104, a third spring 105 and a wedge block 106.

[0048] When the device is in normal state, the third spring 105 is in a compressed state. When sampling is required, the movable sleeve 102 can be controlled to move forward, thereby causing the U-shaped sleeve 103, the squeezing rod 104 and the third spring 105 to move forward. At this time, the squeezing rod 104 will be separated from the wedge block 106, and the rebound of the third spring 105 will drive the squeezing rod 104 to move inward, thereby squeezing the dropper 3, so that the sample in the dropper 3 drips. After the sample in the dropper 3 drips, the movable sleeve 102 is controlled to move backward and reset, thereby causing the U-shaped sleeve 103, the squeezing rod 104 and the third spring 105 to move backward and reset. At this time, the squeezing rod 104 cooperates with the wedge block 106, so that the third spring 105 will be compressed.

[0049] It also includes a transmission assembly 11, which includes a guide rail 111, a moving block 112, a push rod 113, a second gear 114, a first rack 115, a square sleeve 116 and a second rack 117. A guide rail 111 is provided on the lower left side of the blanking frame 2, and a moving block 112 is slidably provided in the guide rail 111. Push rods 113 are connected to the upper and lower sides of the front of the moving block 112, and the push rod 113 cooperates with the moving sleeve 102 on the same side.

[0050] When the threaded rod 5 moves to the rear side, it will drive the second rack 117 to move to the rear side, and then drive the second gear 114 to rotate, thereby driving the first rack 115 to move to the front side, thereby causing the moving block 112 and the push rod 113 to move to the front side, so that the push rod 113 pushes the moving sleeve 102 to move to the front side, and then the device automatically squeezes the dropper 3, thereby reducing the trouble of manual operation; when the threaded rod 5 moves to the front side and resets, it will cause the second rack 117 to move to the front side, and then drive the second gear 114 to rotate in the opposite direction, thereby driving the first rack 115, the moving block 112 and the push rod 113 to move to the rear side and reset, and then control the moving sleeve 102 to move to the rear side and reset.

[0052] When the second rack 117 moves to the rear side, it will drive the contact rod 126 to move to the rear side. When the contact rod 126 moves to contact with the U-shaped plate 125, it will drive the square telescopic rod 122 to rotate around the fixed rod 121 as the axis, and the second torsion spring 123 will deform, so that the special-shaped frame 124 will move to the front side, thereby pushing the placement rod 93 to move to the front side. After the sample is collected, the device automatically shakes and pushes out the collected sample, so as to facilitate people to collect and take the sample. When the second rack 117 moves to the front side and resets, it will drive the contact rod 126 to move to the front side. When the contact rod 126 moves to disengage from the U-shaped plate 125, under the action of the second torsion spring 123, the square telescopic rod 122 rotates and resets around the fixed rod 121 as the axis, and at the same time, the placement rod 93 automatically resets to assist the above-mentioned parts to reverse and reset.
