Referring to fig. 1 and 2, the pressing device further includes a pressing portion 20 and a pressing portion 30 spaced apart from each other in the first direction. Preferably, the pushing part 20 and the pressing part 30 are located at opposite sides of the supporting part 10 in the first direction. The pushing portion 20 is disposed on the supporting portion 10 and is capable of moving between a first position and a second position along a second direction (shown in the Y direction in fig. 1), wherein the second direction is perpendicular to the first direction. Preferably, the pushing part 20 can move relative to the supporting part 10 along a second direction (shown as Y direction in fig. 1).

Preferably, the first stopper portion 11 and the second stopper portion 12 are plate-shaped.

The pushing part 20 can move in the second direction (shown by direction C in fig. 1 and 4) away from the bearing space Q, that is, the pushing part 20 can move in the second direction (shown by direction C in fig. 1 and 4) away from the first limiting part 11, and is switched from the first position to the second position; so as to drive the pressing portion 30 to move in the first direction along the direction (shown by the direction a in fig. 2 to 4) away from the carrying space Q, that is, to drive the pressing portion 30 to move in the first direction along the direction (shown by the direction a in fig. 2 to 4) away from the first limiting portion 11 and the second limiting portion 12.

Alternatively, the pushing part 20 can move in the second direction (shown in the direction D in fig. 1 and 4) toward the carrying space Q, that is, the pushing part 20 can move in the second direction (shown in the direction C in fig. 1 and 4) toward the first position-limiting part 11, and is switched from the second position to the first position; to drive the pressing portion 30 to move in the first direction in a direction (shown in a direction B in fig. 2 to 4) toward the carrying space Q, that is, to drive the pressing portion 30 to move in the first direction in a direction (shown in a direction a in fig. 2 to 4) toward the first stopper portion 11 and the second stopper portion 12, so as to apply a pressing force in the first direction to the slide glass 40 accommodated in the carrying space Q.

Specifically, before the slide glass 40 is placed in the bearing space Q, the pushing part 20 is controlled to move in the second direction in the direction away from the bearing space Q, so as to drive the pressing part 30 to move in the first direction in the direction away from the bearing space Q, and the slide glass 40 is easy to place. After the placement of the slide glass 40 in the bearing space Q is completed, the lower surface of the slide glass 40 is attached to the second limiting portion 12 and is limited by the second limiting portion 12, and the pushing portion 20 is controlled to move in the second direction toward the bearing space Q to drive the pressing portion 30 to move in the first direction toward the bearing space Q, so as to apply a pressing force in the first direction to the slide glass 40 accommodated in the bearing space Q to clamp the slide glass 40 placed in the bearing space Q.

Preferably, referring to fig. 1 and 2, the first position-limiting portion 11 and the pushing portion 20 are located on the same side of the supporting portion 10, and the second position-limiting portion 12 and the pressing portion 30 are located on the same side of the supporting portion 10; after the pressing portion 30 applies the pressing force in the first direction to the slide glass 40, the slide glass 40 is attached to the first stopper portion 11 in the first direction. Further preferably, the second position-limiting part 12 and the pushing-up part 20 are located on the same side of the supporting part 10, and the first position-limiting part 11 and the pressing part 30 are located on the same side of the supporting part 10; after the pressing portion 30 applies the pressing force in the first direction to the slide glass 40, the slide glass 40 is attached to the second stopper portion 12 in the first direction.

Due to the third elastic member 65, one end of the third elastic member 65 is connected to the lever assembly 60, and the other end is connected to the support portion 10, so that the lever assembly 60 can rotate around the rotation shaft in the opposite direction when the third elastic member 65 is converted from the stretching state to the stretching state. The limiting member 67 can limit the end position of the lever assembly 60 rotating reversely around the rotating shaft, so that the lever assembly 60 is limited from shaking when the lever assembly 60 is at the first position.

In addition, when the lever assembly 60 is at the initial position, that is, at the first position, the movement of the lever assembly 60 is limited due to the position-limiting member 67. Preferably, when the lever assembly 60 is in the first position, the end of the first portion 61 of the lever assembly 60, which is not connected to the second portion 62 of the lever assembly 60, abuts against the pushing part 20, so that the swinging of the pushing part 20 in the second direction is also limited.

The invention also provides a microscope system comprising the slide receiving and placing device 1 in any one of the above embodiments.
