The connecting bar 8 is provided with an L-shaped structure, and a moving rail adapted to the connecting bar 8 is opened on the side of the workbench 1, so as to meet the moving requirements of the connecting bar 8.
[0024] Further, referring to Figure 2 It can be known that there are two groups of connecting bars 8 in total. The bottom end of the other group of connecting bars 8 is connected to a moving sleeve 10, and the moving sleeve 10 is sleeved on the outside of a guiding rod 11. The guiding rod 11 is installed inside the workbench 1. A receiving groove adapted to the guiding rod 11 is opened inside the workbench 1. The two ends of the guiding rod 11 are fixedly connected to the inner wall of the receiving groove. Through the mutual cooperation of the moving sleeve 10 and the guiding rod 11, the stability of the alignment plate 9 during the moving process can be ensured.
[0025] Further, referring to Figure 4 It can be known that the bottom end of the alignment plate 9 is evenly provided with holes, and balls 7 are installed inside the holes. Through the mutual cooperation of the holes and the balls 7, the bottom end of the alignment plate 9 can be prevented from directly rubbing against the workbench 1, so as to protect the alignment plate 9 and effectively ensure the service life of the alignment plate 9.
[0026] Further, referring to Figure 2 and Figure 4 It can be known that a buffer pad 14 is glued to the side of the alignment plate 9, and the buffer pad 14 is distributed on the side close to the positioning plate 3. Through the buffer pad 14 made of rubber material, the hard contact between the alignment plate 9 and the test paper can be effectively prevented, so as to protect the test paper.
[0027] Further, referring to Figure 3It can be known that limiting rods 15 are respectively inserted inside two groups of connecting bars 8.
