[0021] Through the above structure, when the transmission operation is implemented, the detection strip is first placed in the storage groove 9 on the arch plate 6. The arch plate 6 can be retracted into the arc groove 5 when not in operation, and can be extended when rotated to the operation position, so that the detection strip in the storage groove 9 can be operated. Figure 3 As shown, the first disc 4 is rotated clockwise to rotate the test strip to the hair lysis solution dropper, and the hair lysis solution to be tested is dropped onto the test strip. The first disc 4 is rotated again, and the test strip is rotated to the bottom of the detector body 12. The liquid on the test strip is tested to detect whether there are drug components. Finally, the first disc 4 is rotated and the test strip in the storage slot 9 is taken out to complete the test.

[0022] See also Figure 2 , Figure 3 As shown, the conveying device also includes a telescopic rod 7 and a spring 8 fixedly connected between the arc groove 5 and the arch plate 6, and the telescopic rod 7 is arranged on the spring 8. Two openings 10 are symmetrically opened on the outer side of the box body 1, and inclined sliding grooves matching with the arch plate 6 are opened on both sides of the opening 10. The arch plate 6 extends out of the box body 1 through the opening 10.

[0023] By providing the opening 10, the arch plate 6 can extend out of the box body 1. After the first disc 4 is rotated, the arch plate 6 is pushed into the arc groove 5 along the inclined slide groove provided on the opening 10 or the inner wall of the box body 1, and the spring 8 is squeezed at the same time. After rotating to the next opening 10 or the inside of the first cavity 2, the arch plate 6 extends out under the rebound effect of the spring 8, and the operation can be continued.

[0024] Preferably, a telescopic rod 7 is sleeved on the outside of the spring 8 so that during the extension and retraction of the arch plate 6 , the arch plate 6 will not bend due to the extrusion of the inclined slide groove or the inner wall of the box body 1 .

When the third disc 20 is idling, the first disc 4 stops rotating, and operations can be performed on the first disc 4.
