When the detection head 4 moves, the power rod 6 fixedly connected to the electric telescopic rod 3 moves accordingly, and cooperates with the hydraulic chamber 5 slidably connected to the power rod 6 piston, so that the pressure in the hydraulic chamber 5 increases, which can drive the gear rod 7 and the gear rod 8 slidably connected to the hydraulic chamber 5 piston to move. The internal rotation of the negative pressure pipe 1 is connected to an arc block 9, the top of which is fixedly connected to a transmission rod 10, and the top of the transmission rod 10 is fixedly connected to a gear 11, which is located at the front end of the gear rod 7, and the gear 11 is in meshing state with the gear rod 7. When the gear rod 7 moves, the gear 11 meshing with it can be driven to rotate, and cooperate with the transmission rod 10 fixedly connected to the gear 11, so that the gear rod 11 meshing with the transmission rod 11 can be driven to rotate. The arc block 9 fixedly connected to the moving rod 10 rotates to close the negative pressure pipeline 1, and the top of the device body 2 is fixedly connected to the sampling chamber 12, and the top of the sampling chamber 12 is rotatably connected to the rotating shaft 13, and the side of the rotating shaft 13 is fixedly connected to the cover plate 22, and the front end of the rotating shaft 13 is fixedly connected to the transmission rod 2 14, and the front end of the transmission rod 2 14 is fixedly connected to the gear 2 15. When the gear rod 2 8 moves, it can drive the gear 2 15 meshing therewith to rotate, so that the transmission rod 2 14 fixedly connected to the gear 2 15 rotates, and the transmission rod 2 14 drives the rotating shaft 13 fixedly connected thereto to rotate, so that the cover plate 22 fixedly connected to the rotating shaft 13 rotates, and the sampling chamber 12 is opened, and the electric telescopic rod 3 can be moved into the sampling chamber 12 for sampling, and the detection head 4 can be cleaned without detection, thereby reducing the situation of being affected by the previous detection results in the case of multiple uses, and improving the accuracy of the detection results.

[0028] During use, when detection is required, the electric telescopic rod 3 is started to drive the detection head 4 fixedly connected to the electric telescopic rod 3 to move. At this time, the power rod 6 fixedly connected to the electric telescopic rod 3 moves accordingly, and cooperates with the hydraulic chamber 5 slidingly connected to the piston of the power rod 6, so that the pressure in the hydraulic chamber 5 increases, which can drive the gear rod 1 7 and the gear rod 2 8 slidingly connected to the piston of the hydraulic chamber 5 to move, and the gear rod 1 7 drives the gear 11 meshing therewith to rotate, and cooperates with the transmission rod 10 fixedly connected to the gear 11 to make the arc block 9 fixedly connected to the transmission rod 10 rotate, and the negative pressure pipeline 1 is closed, and the gear rod 2 8 drives the gear 2 15 meshing therewith to rotate, so that the transmission rod 2 14 fixedly connected to the gear 2 15 rotates, and the transmission rod 2 14 drives the rotating shaft 13 fixedly connected thereto to rotate, so that the cover plate 22 fixedly connected to the rotating shaft 13 can be rotated, and the sampling chamber 12 can be opened, and the electric telescopic rod 3 can be moved into the sampling chamber 12 for sampling.

[0029] Embodiment 2

[0030] See also Figure 1-5 , based on the first embodiment, a delay component is provided inside the hydraulic compartment 5;

[0031] The delay component includes a rotating plate 16, which is rotatably connected to the hydraulic chamber 5. An elastic rod 17 is fixedly connected to the side of the rotating plate 16. Two elastic rods 17 are provided, and the two elastic rods 17 are symmetrically distributed about the rotating plate 16. When the power rod 6 moves, it cooperates with the hydraulic chamber 5 that is slidably connected to the piston of the power rod 6. Due to the rotating plate 16 that is rotatably connected to the inner wall of the hydraulic chamber 5, and the elastic rod 17 that is fixedly connected to the rotating plate 16 at one end and fixedly connected to the inner wall of the hydraulic chamber 5 at the other end, the force in the hydraulic chamber 5 is preferentially transmitted to the gear rod 1 7, so that the negative pressure pipeline 1 is preferentially closed. The power rod 6 continues to move, so that the rotating plate 16 squeezes the elastic rod 17 and rotates. At this time, the force in the hydraulic chamber 5 can be transmitted to the gear rod 2 8, so that the cover plate 22 rotates, and the sampling chamber 12 is opened, so that the negative pressure pipeline 1 is preferentially closed, and the sampling chamber 12 is opened later, thereby reducing the possibility of liquid outflow when the two are started synchronously, and avoiding unnecessary waste.

[0032] During use, on the basis of Example 1, when the power rod 6 moves, it cooperates with the hydraulic chamber 5 slidably connected to the piston of the power rod 6, because the rotating plate 16 rotatably connected to the inner wall of the hydraulic chamber 5, and the elastic rod 17 with one end fixedly connected to the rotating plate 16 and the other end fixedly connected to the inner wall of the hydraulic chamber 5, the force in the hydraulic chamber 5 is preferentially transmitted to the gear rod 1 7, so that the negative pressure pipeline 1 is preferentially closed, and the power rod 6 continues to move, so that the rotating plate 16 squeezes the elastic rod 17 and rotates. At this time, the force in the hydraulic chamber 5 can be transmitted to the gear rod 2 8, so that the cover plate 22 rotates and the sampling chamber 12 is opened.

When the electric telescopic rod 3 is extended to a detectable height, it stops, so that the fixing groove 21 provided at the front end of the electric telescopic rod 3 moves to the position of the clamping rod 20. At this time, the clamping rod 20 loses its restriction and can move into the fixing groove 21 under the action of the spring 19 fixedly connected thereto, clamping the electric telescopic rod 3, thereby improving the stability of the device during detection.

[0036] During use, on the basis of Embodiment 1 and Embodiment 2, when the electric telescopic rod 3 is extended to a detectable height, it stops, so that the fixed groove 21 opened at the front end of the electric telescopic rod 3 moves to the position of the clamping rod 20.
