The clip 20 includes a first arm 21, a second arm 22 and a rotating portion 23. The second arm 22 is used to press against the glass slide 50. The circumference of the rotating portion 23 is respectively connected to the first arm 21 and the second arm 22. The rotating portion 23 is rotatably connected to the base plate 10, so that when the first arm 21 is driven to rotate by an external force, the second arm 22 will rotate synchronously. The pre-pressed member includes a sealing cover 40 and a torsion spring 41. The two ends of the torsion spring 41 are respectively fixedly connected to the base plate 10 and the rotating portion 23. The torsion spring 41 can provide a rotational force for the rotating portion 23, and the rotational force can drive the rotating portion 23 to rotate relative to the base plate 10, thereby driving the second arm 22 to press against the glass slide 50. The sealing cover 40, the clip 20 and the base plate 10 enclose a receiving cavity, and the torsion spring 41 is arranged in the receiving cavity.
[0029] When in use, the first arm 21 is driven to rotate, and then the second arm 22 is driven to rotate synchronously through the rotating part 23, so as to drive the second arm 22 away from the position where the glass slide 50 is located, so as to replace, load and unload the glass slide 50, and then release the first arm 21, and the clamp 20 is driven by the rotational force of the torsion spring 41 to return to its original position, and the second arm 22 is pressed against the newly loaded glass slide 50 for subsequent scanning. The torsion spring 41 is arranged in the accommodating cavity surrounded by the sealing cover 40, the clamp 20 and the bottom plate 10.
