[0036] The fixing component 24 includes a V-shaped clamp 241 fixedly connected to the bottom end of the connecting rod 222 and rotatably connected to the bottom end of the support frame 13, a fixing strap 242 fixedly connected to one side of the V-shaped clamp 241, and an adjusting buckle 243 provided on the other side of the V-shaped clamp 241.

[0040] Example 2

[0041] The operating principle of this utility model:

[0042] When using this device to test the drug content of hair, the operator first opens the front cover plate 312 of the grinding block 31, cuts the collected hair to be tested into several pieces, and puts them into the grinding groove 311 of the grinding block 31, then closes the cover plate 312. Next, repeatedly press the pressure plate 321. Under the rebound action of the elastic element 33, the grinding blade 322 continuously cuts the hair in the grinding groove 311 until the hair is pulverized. Open the rear cover plate 312 of the grinding block 31 and place the test strip at the rear end of the grinding groove 311. Rotate the grinding block 31 to tilt it, pouring the hair fragments in the grinding groove 311 into the test strip. Pour the collected hair fragments into the lysis solution bottle, and then place the lysis solution bottle containing the hair fragments into the V-shaped clamp 241. Adjust the lysis solution bottle to be secured to the V-shaped clamp 241 by the cooperation of the fixing strap 242 and the adjusting buckle 243.

[0043] Next, the operator presses the movable sleeve 232, causing it to move downwards along the rotating rod 231, which in turn moves the spiral blade 233 and the movable ratchet sleeve 235 downwards. The movable ratchet sleeve 235 rotates under the trajectory of the spiral blade 233, and the ratchet teeth in the movable ratchet sleeve 235 and the fixed ratchet sleeve 234 engage. The rotation of the movable ratchet sleeve 235 causes the fixed ratchet sleeve 234 to rotate, which in turn drives the rotating rod 231 to rotate. The rotation of the rotating rod 231 causes the connecting frame 22, the rotating ring 21, and the fixing assembly 24 to rotate synchronously. After the movable sleeve 232 moves to the lower end of the cutter, it is pulled up to the upper end. At this time, the spiral blade 233 causes the movable ratchet sleeve 235 to disengage from the fixed ratchet sleeve 234 (as shown in the attached diagram). Figure 9 As shown, due to inertia and the kinetic energy accumulated from previous engagement, the rotating rod 231 continues to rotate. By repeatedly pressing and pulling the movable sleeve rod 232, the lysate bottle achieves continuous rotation and shaking in the same direction. The mixing is stopped after 1-2 minutes, timed by timer 42.

[0044] After pressing, use a dropper to remove the supernatant from the lysis buffer bottle and drop it into the test card 41. After a time of 5-8 minutes, observe the test results on the test card.

[0045] This invention significantly improves the sample processing efficiency, extraction effect, and operational reliability of hair drug detection through efficient grinding, stable mixing, and reliable fixing devices.
