The tube-breaking structure (100) comprises a main body (110), a tube-breaking component (120) and a flow-guiding component (130). The tube-breaking component (120) comprises a cutting element (121) and a spreading element (122) sequentially arranged from top to bottom. The tube-breaking structure (100) can be used to break a sample tube (300) in a closed state, such that a sample solution in the sample tube (300) is mixed with a reaction solution, after which subsequent operations and observations may be performed, thereby ensuring that the entire test process is completely closed without any risk of exposure or infection. The tube-breaking structure (100) comprises multiple cutting elements (121) and spreading elements (122). The invention simplifies the steps of breaking a sample tube (300), reduces the pressing force required to break the sample tube (300), and enables a solution in the sample tube (300) to be quickly discharged by means of a flow-guiding member (130), thereby improving mixing efficiency.
