The adjuster 43 may have a rod-like structure, a plate-like structure, or the like. By providing the buffer structure 431 at the end of the adjusting member 43 away from the adjusting driving member 42, the buffer structure 431 can abut against the edge of the opening end of the reaction vessel 90 to increase the contact area between the outer wall surface of the reaction vessel 90 and the adjusting member 43, and the buffer structure 431 can also provide a buffer effect when the adjusting member 43 contacts the reaction vessel 90.
The buffer structure 431 may have various shapes, for example, the buffer structure 431 may be a circular arc structure formed at the end of the adjusting member 43, the circular arc structure may increase the contact area between the edge of the reaction container 90 and the outer wall surface of the adjusting member 43, and the circular arc structure may provide a buffer effect when the adjusting member 43 contacts the reaction container 90; or the buffer structure 431 may be triangular, and when the adjusting member 43 moves downward, the triangular stop structure will push the blocked reaction container 90 back to the upper side of the chute 33, so as to disturb the reaction container 90; the reaction vessel 90 is prevented from sliding downwards from a static state after the adjusting piece 43 is completely separated downwards, and the reaction vessel 90 is possibly retained and does not slide downwards after being static; therefore, the buffer structure is triangular, so that the reaction vessel 90 can be retained without sliding down after being separated from the adjusting member 43, and the sliding controllability of the reaction vessel 90 in the sliding chute 33 is improved.
