[0026] The effect achieved by the whole embodiment 1 is that when the plant specimen needs to be pressed, one of the pressing blocks 603 is inserted into the mounting plate 2 and fixed by the magnet 4, and then the other pressing block 603 is placed along the limiting frame 7 on the support frame 1, and then the plant specimen is placed on the bottom pressing block 603, and then the mounting plate 2 is driven downward by the starting of the electric push rod 5, so that the two pressing blocks 603 contact and press the plant specimen into shape, and under the action of the two water absorption papers 602, the liquid generated during pressing can be absorbed, ensuring the molding effect, when the water absorption paper 602 needs to be replaced, the pressing block 603 can be pulled outwards through the pull slot on the pressing block 603, so that it is separated from the magnet 4, then the pressing block 603 is taken off from the mounting plate 2, then the connecting rod 606 is pulled outwards by the pull block, so that it is separated from the limiting block 604, then the rotating rod 601 is rotated, the rotating rod 601 is taken out of the limiting slot 605, the water absorption paper 602 is not limited, and then the water absorption paper 602 is taken off from the pressing block 603, then the two ends of the new water absorption paper 602 are inserted into the limiting slot 605, then the connecting rod 606 is pulled again, so that the sliding rod 607 slides along the sliding slot 608 and stretches the spring 609, reversely rotates the rotating rod 601, and moves to the limiting slot 605, releases the connecting rod 606, under the action of the spring 609, the sliding rod 607 is reset, the connecting rod 606 moves to the bottom of the two limiting blocks 604, and the rotating rod 601 is limited, so that the water absorption paper 602 is fixed on the pressing block 603 by the rotating rod 601, which is simple and convenient, and the specimen pressing effect is better.

[0027] As shown in Figures 1-5 The output end of the electric push rod 5 is movably penetrated into the top of the support frame 1, and the output end of the electric push rod 5 is fixedly connected with the connecting frame 3.

[0028] The effect achieved by the whole embodiment 2 is that when the electric push rod 5 moves the mounting plate 2 downward, the pressure can be dispersed around the mounting plate 2 under the action of the connecting frame 3, the specimen is uniformly stressed during pressing, and the flatness of the specimen is improved.

[0029] Working principle: When it is necessary to press the plant specimen, one of the pressing blocks 603 is inserted into the mounting plate 2 and fixed by adsorption through the magnet 4, and then the other pressing block 603 is placed along the limit frame 7 on the support frame 1. After the plant specimen is placed on the pressing block 603 at the bottom, the electric push rod 5 is started to drive the mounting plate 2 to move downward. At the same time, under the action of the connecting frame 3, the pressure is dispersed around the mounting plate 2. The specimen is subjected to uniform force during the pressing process, so that the two pressing blocks 603 are in stable contact and the plant specimen is pressed and formed. At the same time, under the action of the two absorbent papers 602, the liquid generated during the pressing can be absorbed to ensure the forming effect. When the absorbent paper 602 needs to be replaced, it can be pulled outward through the groove on the pressing block 603 to disengage it from the magnet 4, and then the pressing block 603 is removed from the mounting plate 2, and then through After the pull block drives the connecting rod 606 to pull outward and separate it from the limit block 604, it drives the rotating rod 601 to rotate and remove the rotating rod 601 from the limit groove 605. If the absorbent paper 602 is not limited, the absorbent paper 602 can be removed from the pressing block 603. Then, after the two ends of the new absorbent paper 602 are inserted into the limit groove 605, the connecting rod 606 is pulled again to make the sliding rod 607 slide along the sliding groove 608 and drive the spring 609 to stretch. After the rotating rod 601 is rotated in the opposite direction and moved to the limit groove 605, the connecting rod 606 is released. Under the action of the spring 609, the sliding rod 607 is driven to return to its original position, so that the connecting rod 606 moves to the bottom of the two limit blocks 604, limiting the rotating rod 601, thereby fixing the absorbent paper 602 on the pressing block 603 through the rotating rod 601, which is simple and convenient, and has a better specimen pressing effect.
