Description

[0002] The adsorption tube is the main sampling device used in air detection. When the adsorption tube is sampling, the sampling head of the adsorption tube needs to be cut off to facilitate air sampling.

[0003] At present, when the sampling head of the adsorption tube is cut, the stability of the cut end is prone to be poor. In the process of cutting the sampling head of the adsorption tube, the adsorption tube cannot be fixed, thereby affecting the sampling of the air by the adsorption tube, and the adsorption tube needs to be covered with rubber caps at both ends of the adsorption tube after sampling. In order to prevent the air retained in the rubber cap from entering the adsorption tube and affecting the test accuracy, the test personnel often pinch the rubber cap with their hands to expel the internal air while putting it on the end of the adsorption tube.

[0042] The working principle of the present invention is as follows: when in use, after placing the adsorption tube 21 inside the placement groove 6, first pull the rotating ring 16, the rotating ring 16 pulls the extension rod 15 to slide, the sliding of the rotating ring 16 causes the fixed rod 24 to be separated from the inside of the fixed plate 5, and then by rotating the rotating ring 16, the rotating ring 16 drives the rotation of the extension rod 15, and the extension rod 15 drives the No. 1 screw 10 to rotate under the limitation of the convex strip 25 and the slide groove 26, the rotation of the No. 1 screw 10 drives the rotation of the No. 1 pulley 130 and the No. 2 pulley 131 on the surface, and the No. 1 pulley 130 and the No. 2 pulley 131 drive the No. 3 pulley 134 and the No. 2 belt 135. The pulley 132 and the fourth pulley 133 rotate, thereby driving the second screw 11 and the third screw 12 to rotate at the same time, and the rotation of the first screw 10, the second screw 11 and the third screw 12 drives the two first screw sleeves 140 and the second screw sleeve 141 to slide, thereby driving the two first push rods 142 and the second push rod 143 to slide, and when the two first push rods 142 and the second push rod 143 collide with the third push rod 144, the third push rod 144 is pushed to slide, and the sliding of the third push rod 144 drives the sliding of the mounting plate 145, and the sliding of the mounting plate 145 drives the two sets of first fixing blocks 8 and second fixing blocks 9 to slide out , thereby fixing the position of the adsorption tube 21 inside the placement groove 6 to prevent the adsorption tube 21 from shaking, the two groups of No. 1 fixing blocks 8 and No. 2 fixing blocks 9 slide out, push the swivel 16, and insert the fixing rod 24 into the inside of the fixing plate 5 to locate its position, and then press the No. 2 push plate 30, the No. 2 push plate 30 pushes the push rod 18 to slide, and the sliding of the push rod 18 pushes the card plate 19 to slide down, so that the card plate 19 contacts the surface of the fixing plate 5, and at the same time, the sliding of the card plate 18 drives the two groups of cutting knives 20 to slide down, and the adsorption tube 21 is cut off by the sliding of the two groups of cutting knives 20, so that the adsorption tube 21 can be quickly cut off, When the cut adsorption tube 21 needs to be sealed, the push plate 231 is pushed to slide. The sliding of the push plate 231 pushes the sliding of the moving rod 230. The sliding of the moving rod 230 pushes the sliding of the sealing cover 232. The air inside the rubber sleeve 22 can be pushed out by the sliding of the sealing cover 232.
