Embodiment 1

[0018] as attached figure 1 , 2 As shown, a scraper structure for cell collection includes a main body rod 1 and a scraper structure 2 arranged at the front end of the main body rod 1. The scraper structure 2 includes a base 21 connected to the main body rod 1 and a scraper 22 arranged at the front end of the base 21. The main body rod 1 includes a hollow protective outer tube 101 and an operating inner rod 102 arranged in the protective outer tube 101. The operating inner rod 102 extends out of the protective outer tube 101, and the operating inner rod 102 can be operated at the end of the protective outer tube. The tube 101 rotates along the circumferential direction, and the front end of the protective outer tube 101 is provided with a connecting part 1021, which is a spherical inner groove. The connecting part 1021 of the groove and the matching part 211 of the spherical body are connected in cooperation. In this connection mode, the protection outer tube 101 and the base...
