As a preferred embodiment of the present invention, the first clamping device 2 is disposed outside the clamping hole 13, and initially, the specimen box or the cutting box is placed in the clamping hole 13.
As a preferred embodiment of the present invention, the top plate 10 is provided with a plurality of sliding grooves 12, and the sliding grooves 12 are communicated with the clamping holes 13;
the first clamping box 2 comprises a plurality of sliding clamping magnetic blocks 20 and a plurality of electromagnetic seats 21, and each sliding groove 12 is internally provided with one sliding clamping magnetic block 20 and one electromagnetic seat 21.
As a preferred embodiment of the present invention, the magnetic slide clamp block 20 is connected to one end of the slide groove 12 through a restoring spring 22. The sliding clamping magnetic block 20 is prevented from falling out of the sliding groove 12 from the clamping hole 13, and the sliding clamping magnetic block 20 can be pulled back to play a role in loosening the box body.
As a preferred embodiment of the present invention, any two sliding clamping magnetic blocks 20 are symmetrical about the center of the clamping hole 13. And the energizing voltage and the energizing current of each electromagnetic seat 21 are the same, so that when each electromagnetic seat 21 is energized, the generated electromagnetic fields have the same size and different directions, the repulsion force generated by each electromagnetic seat 21 can enable the sliding clamping magnetic block 20 to displace towards the center of the clamping hole 13, and because the repulsion force is the same, the size and the magnetic force of the sliding clamping magnetic block 20 are the same, and the distance from the center of the clamping hole is also the same, the clamping force of each sliding clamping magnetic block 20 to the outer side of the box body is the same, so that the stability of the clamping force is ensured.

The clamping principle of the first cassette device is as follows:
all the electromagnetic seats 21 are controlled by the controller to be electrified simultaneously, the electromagnetic seats 21 generate an electromagnetic field, the magnetic field is opposite to the magnetic field of the magnetic block 20 in the corresponding sliding chute 12, so that magnetic repulsion is generated, the magnetic block 20 is enabled to move towards the center direction of the clamping hole 13 along the track of the sliding chute 12, and the box body or the box cover is clamped;
when the box body or the box cover needs to be loosened, the current of all the electromagnetic seats is cut off, the electromagnetic seats do not generate an electromagnetic field at the moment, and the magnetic block 20 is displaced towards the direction away from the clamping hole 13 under the action of the spring tension of the restoring spring 22 to loosen the box body or the box cover.
As a preferred embodiment of the present invention, the second cartridge clamping mechanism 5 comprises a plurality of rotating shafts 51 mounted on the clamping base through bearings 50, each rotating shaft 51 is connected with a clamping plate 52, two adjacent rotating shafts 51 are connected through bevel gears 53, two adjacent bevel gears are meshed with each other, one of the rotating shafts 51 is connected with a slave gear 6, the slave gear 6 is meshed with a master gear 7, and the master gear 7 is connected with a motor 8. The motor 8 is arranged at the bottom end or the side part of the top surface of the clamping seat through a motor shell.
As a preferred embodiment of the present invention, the clamping end of the clamping plate 52 is provided with a buffer strip 54. Preferably, the buffer strips 54 can increase the friction force of the clamping plates 52 against the lateral surfaces of the box body so as to avoid slipping, and have the buffer performance so as to avoid the clamping plates 52 from clamping the box body and avoid the end parts of the clamping plates 52 from being worn due to excessive clamping force. Similarly, the clamping end of the magnetic sliding clamp block 20 can also fix a buffer block or a buffer sleeve, such as a rubber block, a rubber strip, or a rubber sleeve.
The clamping principle of the second clamping box device is as follows:
starting the motor 8, controlling the motor to rotate forward by the controller, driving the main gear to rotate with the driven gear, driving the rotating shafts 51 to rotate, driving all the rotating shafts 51 to rotate simultaneously through the bevel gears 53, thereby enabling the top ends of all the clamping plates 52 to rotate towards the center, and slowly clamping the side part of the box body;
when the box body needs to be removed, the controller controls the motor to rotate reversely, all the clamping plates 52 rotate reversely, the top ends of the clamping plates 52 are far away from each other and descend, and therefore the box body is loosened.
The above description is only an example of the preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and those skilled in the art should be able to realize the equivalent alternatives and obvious variations of the present invention.
