During the process of the limiting ring 302a and the built-in ring 302b rotating in the first direction, the abutting pressing component 303 is driven, and the abutting pressing component 303 presses the test block component 201, and the test block component 201 rotates in the first direction to the outlet 102a. It should be noted that the number of the positioning inner frames 302c is plural and corresponds one-to-one to the position of the test block component 201. The other structures are the same as those in Embodiment 3. Operation process: During the process of the rotating ring component 302 rotating the pressing test block component 201, the positioning post 402b first abuts against the lifting segment N1, and the lifting segment N1 of the Under action, the positioning post 402b moves the limiting rod 402a and the movable post 401c. The movable column 401c drives the pressure ring 401d to reset the spring 401b. As a result of the pressing, the reset spring 401b is deformed, and the position of the test block component 201 is reset. When the position of the outlet 102a is reached, the positioning post 402b is moved from the translation segment N2 to the At this time, the reset spring 401b presses the pressing ring 401d, and the movable column 40 1c quickly rebounds, causing the limiting rod 402a to move the positioning post 402b The positioning post 402b is driven to rebound quickly, and the positioning post 402b is driven to rebound quickly. 3, rotation problems of the rotating ring component 302 can be avoided.

[0009] Example 5 6 and 7 to 9, unlike the above embodiment, in this embodiment, In order to avoid the problem of the test block part 201 remaining on the side coming off, the device is The second positioning component 102 further includes a fall-prevention member 500. The fall-prevention member 500 is fixed on the second positioning component 102. The fixed shaft 501 is fixed to the fixed shaft 501, and the swinging member 502 is rotatably fitted on the fixed shaft 501. In addition, the swing member 502 is connected to the limiting rod 402a, and the sliding process of the limiting rod 402a During this process, the swinging member 502 is driven to swing, and the swinging member 502 moves away from the test member 200. The test member 200 is then swung upward so as to be released, and the swing member is then swung downward so as to be brought into contact with the test member 200 and positioned. The sensor swings in the opposite direction. The second guide member 202b includes an extension column 202b-1 fixed on the test block component 201, The second sub-rail 101b-2 / fourth sub-rail 101b-3 are fitted to the outside of the extension column 202b-1. a sliding block 202b-2 slidably connected within the sliding block 102c-2; 202b-2 can slide inside the inner sliding grooves on the second sub-rail 101b-2 and the fourth sub-rail 102c-2. It is possible to do so. One end of the swing member 502 is connected to the limiting rod 402a, and the other end abuts on the extension column 202b-1, making it possible to position the test block component 201. One end of the swing member 502 connected to the limiting rod 402a is the jogging end 502a. A jogging groove 40 2a-1 is opened on the limiting rod 402a, and the jogging end 502a is slidably connected to the jogging groove 402a-1. One end of the swing part 502 away from the jogging end 502a is the abutting end 502b. When the limiting rod 402a moves upward, it rotates the jogging end 502a upward, and the swing member 502 swings downward so that the abutting end 502b abuts on the extension column 202b-1. When the limiting rod 402a moves downward it moves the jogging end 502a downward, and the swing member 502 swings upward, and the abutting end 502 b disengages from the extension column 202b-1. A recovery groove 102d is opened on the second positioning part 102. The abutting end 502b has an inner extension bump 502b-1 that protrudes inward. Due to the inner extension bump 502b-1, when the abutting end 502 b swings downward, it abuts on the extension column 202b-1. When the abutting end 502b swings upward it enters the inside of the recovery groove 102d, and the inner extension bump 502b-1 can avoid preventing the movement of the test block component 201. Furthermore, a contact protrusion 402a-2 is provided on the side wall of the limiting rod 402a. The extraction port 10 2a penetrates to the inner track groove L2 and the side rail groove L1, and the guide assembly 202 can disengage from the inside of the inner track groove L2 and the side rail groove L1. When the test block component 201 reaches the corresponding position of the extraction port 102a, the positioning post 40 2b disengages from the translation segment N2, and at this time, the reset spring 401b presses the pressing ring 40 1d to move the movable column 401c upward and drive the limiting rod 402a upward so that the abutting protrusion 402a-2 moves upward together with the limiting rod 402a and the abutting protrusion 402a-2 is positioned on the extension column 2 02b-1 on the test block part 201 at the outlet 102a. After the extension column 202b-1 receives the force, the test block part 201 is moved upward so that the test block part 201 disengages from the placement track S from the outlet 102a, preventing the operator from taking the test block part 201. In this process, the limiting rod 402a moves upward, the swing member 502 swings downward, and abuts against the remaining test block parts 201 remaining in the placement track S to restrict them. At this time, the remaining test block parts 201 are restricted between the anti-falling member 500 and the abutting and pressing part 303, so that the problem of the remaining test block parts 201 detaching from the inside of the placement track S can be avoided. Specifically, the abutting and pressing part 303 includes a synchronous tube 303a fixed on the rotating ring part 302, a built-in spring 303b provided inside the synchronous tube 303a, and a pressing column 303c with one end abutting against the test block part 201 and the other end extending inside the synchronous tube 303a and abutting against the built-in spring 303b included. Here, the synchronous tube 303a and the pressing column 303c have a coaxial relationship with the second positioning part 102 and the first positioning part 101 respectively. In the restricted state where the swing member 502 abuts against the extension column 202b-1, the rotating ring part 302 rotates in the first direction. At this time, the synchronous tube 303a is rotated in the first direction, and at this time, the test block part 201 is abutted against the swing member 502 In a positioned state, the pressing column 303 is in contact with the test block component 201 at this time Since c cannot move, the built-in spring 303b is compressed by the pressing column 303c and the synchronization pipe 303a . During the rotation process of the positioning inner frame 302c, the lifting segment N1 contacts the positioning column 402b , the positioning column 402b moves downward, driving the limiting rod 402a and the movable column 401c to move downward. At this time, the swing member 502 swings upward, releasing the contact with the test block component 201. The elastic force of the built-in spring 303b is instantaneously applied to the test block component 201 through the pressing column 303c , rotating the test block component 201 . Other structures are the same as those in Embodiment 4 Operation process: When the test block component 201 reaches the corresponding position of the outlet 102a, the positioning column 402b disengages from the translation segment N2. At this time, the reset spring 401b presses the movable column 401c upward through the pressing ring 401d, driving the limiting rod 402a upward . At this time, the contact protrusion 402a-2 moves upward together with the limiting rod 402a , and the contact protrusion 402a-2 is located on the extension column 202b-1 on the test block component 201 at the outlet 102a . After the extension column 202b-1 receives the force, the test block component 2 01 is moved upward, and the test block component 201 disengages from the placement track S or the outlet 102a, preventing the operator from taking the test block component 201. During this process, the limiting rod 402a moves upward, driving the swing member 502 to swing downward, contacting and restricting the test block component 201 remaining in the placement track S, and at this time, the remaining test block The locking component 201 is restricted between the anti-drop member 500 and the contact pressing component 303, and the remaining test b The problem that the locking component 201 detaches from the inside of the arrangement track S can be avoided.
