The bottom has at least one first positioning portion. The lower cover has at least one second positioning portion, and at least one third positioning portion. The lower cover is detachably disposed on the bottom base and positioned with the first positioning portion through the second positioning portion. The upper cover has at least one fourth positioning portion and is detachably disposed on the bottom base. The upper cover is positioned with the third positioning portion through the fourth positioning portion. An observation region is formed between the upper cover and the lower cover. The rotation cover is detachably disposed on the bottom base to limit the upper and lower covers on the bottom base. The rotation cover is adapted to rotate to be locked or released by the bottom base. ## Claims ### Claim 1 A observation carrier for a microscope, comprising: a bottom base comprising at least one first positioning portion; a lower cover comprising at least one second positioning portion and at least one third positioning portion, wherein the lower cover is detachably disposed on the bottom base and is positioned with the at least one first positioning portion through the at least one second positioning portion; an upper cover comprising at least one fourth positioning portion, wherein the upper cover is detachably disposed on the bottom base such that the lower cover is located between the bottom base and the upper cover, the upper cover is positioned with the at least one third positioning portion through the at least one fourth positioning portion, an observation region is formed between the upper cover and the lower cover, and the observation region is adapted to carry a sample; and a rotation cover detachably disposed on the bottom base to limit the upper cover and the lower cover on the bottom base, wherein the rotation cover is adapted to rotate relative to the bottom base to be locked by the bottom base or to be released by the bottom base. ### Claim 2 (depends on 1) The observation carrier for a microscope according to claim 1, wherein the rotation cover is adapted to rotate relative to the bottom base along a rotation axis, and the at least one first positioning portion and the at least one second positioning portion are mutually positioned to prevent the lower cover from rotating relative to the bottom base along the rotation axis. ### Claim 3 (depends on 1) The observation carrier for a microscope according to claim 1, wherein the rotation cover is adapted to rotate relative to the bottom base along a rotation axis, and the at least one third positioning portion and the at least one fourth positioning portion are mutually positioned to prevent the upper cover from rotating relative to the lower cover along the rotation axis. ### Claim 4 (depends on 1) The observation carrier for a microscope according to claim 1, wherein one of the at least one first positioning portion and the at least one second positioning portion is protruding, and the other of the at least one first positioning portion and the at least one second positioning portion is concave. ### Claim 5 (depends on 1) The observation carrier for a microscope according to claim 1, wherein one of the at least one third positioning portion and the at least one fourth positioning portion is protruding, and the other of the at least one third positioning portion and the at least one fourth positioning portion is concave. ### Claim 6 (depends on 1) The observation carrier for a microscope according to claim 1, wherein the lower cover comprises a first window, the upper cover comprises a second window, and the observation region is formed between the first window and the second window. ### Claim 7 (depends on 1) The observation carrier for a microscope according to claim 1, comprising a first sealing ring and a second sealing ring, wherein the first sealing ring is disposed between the bottom base and the lower cover and surrounds the observation region, and the second sealing ring is disposed between the bottom base and the upper cover and surrounds the observation region. ### Claim 8 (depends on 1) The observation carrier for a microscope according to claim 1, wherein the bottom base comprises an accommodating space, and the accommodating space is adapted to accommodate the lower cover, the upper cover, and the rotation cover. ### Claim 9 (depends on 8) The observation carrier for a microscope according to claim 8, wherein an inner edge of the accommodating space comprises an annular groove, a periphery of the rotation cover comprises at least one protrusion, and the at least one protrusion is adapted to extend into the annular groove to prevent the rotation cover from being separated from the bottom base. ### Claim 10 (depends on 9) The observation carrier for a microscope according to claim 9, wherein a top surface of the bottom base comprises at least one notch, the at least one notch communicates with the annular groove, and the at least one protrusion is adapted to correspond to the at least one notch as the rotation cover rotates.
