referring to fig. 9, a driving ring 7 which is coaxial with the carrying cylinder 4 is rotatably mounted on the carrying plate 5, two T-shaped plates 8 are longitudinally arranged on the carrying plate 5 at intervals, the T-shaped plates 8 are longitudinally slidably mounted on the carrying plate 5, referring to fig. 10, squeezing plates 10 are respectively transversely slidably mounted in the T-shaped plates 8, and the two squeezing plates 10 which are positioned on the same transverse side are connected with a driving device which is arranged in the T-shaped plates 8, it is set that when the squeezing plates 10 are respectively contracted into the corresponding T-shaped plates 8, the two T-shaped plates 8 move in opposite directions without touching the air bag on the dropper 6, when the chromosome dropper starts to work, the two squeezing plates 10 which are positioned on the same transverse side are driven by the driving device arranged in the T-shaped plates 8 to synchronously slide out of the T-shaped plates 8 and the air bag on the dropper 6 is positioned between the two squeezing plates 10 (at this, two squeezing plates 10 on a standby station are contracted in T-shaped plates 8, as shown in figure 10), a driving ring 7 which is coaxially arranged with a bearing barrel 4 is rotatably arranged on a carrying plate 5, and the driving ring 7 is matched with the two T-shaped plates 8, so that the driving ring 7 rotates for a half circle to drive the two T-shaped plates 8 to move oppositely once, in the process of rotating for the half circle of the driving ring 7, the driving ring 7 firstly drives the two T-shaped plates 8 to move downwards to further squeeze the air bags of the dropper 6 on a working position through the two squeezing plates 10, at the moment, cell liquid in the dropper 6 drips downwards, when no force is applied between the driving ring 7 and the two T-shaped plates 8, the two T-shaped plates 8 move towards a direction away from each other under the action of a telescopic spring 9 and finally move to an initial position (at the moment, the two squeezing plates 10 are not contacted with the air bags on the, that is, the dropper 6 stops dropping the cell sap downward);

when the device is in a working state, initially, one of the glass slides 3 arranged on the circular plate 48 is adjusted to a position corresponding to the dropper 6, namely, one of the glass slides 3 is positioned right below the dropper 6 positioned at the working position, the motor 11 arranged on the base 1 (the motor 11 is electrically connected with an external power supply through a lead) drives the extrusion transmission device to act so as to drive the driving ring 7 to rotate along the object carrying plate 5, meanwhile, the motor 11 drives the circular plate 48 to rotate through the intermittent transmission device, and when the motor 11 drives the driving ring 7 to rotate for half a circle through the extrusion transmission device (in the process, the driving ring 7 rotates to drive the two T-shaped plates 8 to move towards the direction close to each other firstly, so that the telescopic springs 9 are compressed, and after the corresponding angle is rotated, when no mutual acting force exists between the driving ring 7 and the T-shaped plates 8, at this time, the two T-shaped plates 8 move towards the initial position under the action of the extension spring 9, when the two T-shaped plates 8 move from the beginning to the final position, the dropper 6 finishes the chromosome dropping work on one of the slides 3), the process includes a time point, namely, after the two T-shaped plates 8 move to the initial position again (at this time, the dropper 6 stops the chromosome dropping work), at this time, the motor 11 drives the circular plate 48 to rotate for a certain angle through the intermittent transmission device, so that the other slide 3 without the cell sap is moved to the position right below the dropper 6, and then the process is repeated, namely, the automatic dropping work of the chromosomes and the automatic transfer work of the slide 3 are realized.

Example 2, on the basis of example 1, referring to fig. 4, we have a rotating shaft 12 driven by a motor 11 and coaxially arranged with a carrying cylinder 4 on a base 1, referring to fig. 5, we have a first gear 13 fixed on the rotating shaft 12 and the first gear 13 is engaged with a second gear 14 rotatably mounted on the base 1, the intermittent transmission device includes an intermittent pulley group 15 connected with the second gear 14, referring to fig. 3, the intermittent pulley group 15 drives an intermittent plate 16 rotatably mounted on the base 1, we have an intermittent shaft 17 fixed on the intermittent plate 16, a moving plate 19 rotatably mounted on the base 1 and a plurality of arc-shaped grooves 18 matched with the intermittent moving plate 17 are arranged on the outer circumferential surface of the moving plate 19 and the intermittent plate 16 at intervals (when we arrange the arc-shaped grooves 18, we make them correspond to the number of glass slides 3, that is, the number of the glass slides 3 placed on the circular plate 48 is the number of the arc-shaped grooves 18 on the moving plate 19, and when the intermittent plate 16 rotates one turn under the driving of the motor 11 through the intermittent pulley group 15, the first gear 13 and the second gear 14, the moving plate 19 can be driven to rotate one turn by N through the intermittent shaft 17 and the arc-shaped grooves 18 which are matched (assuming that the moving plate 19 is provided with the N arc-shaped grooves 18);

it is to be noted here that: the intermittent plate 16 drives the moving plate 19 to rotate for a half of N times through the intermittent shaft 17, which occurs after the two T-shaped plates 8 move from the initial positions to each other and move to the initial positions again (the two T-shaped plates 8 finish moving from the initial positions to the initial positions again under the driving of the extrusion transmission device through the motor 11, and the process finishes the chromosome dripping operation on one of the glass slides 3), and then the motor 11 drives the intermittent plate 16 through the intermittent pulley set 15 and realizes the driving of the intermittent shaft 17 to match with the arc-shaped groove 18 and drives the moving plate 19 to rotate for a half of N times, so that the next glass slide 3 is moved to the position right below the dropper 6, and then the process is repeated to start the chromosome dripping operation on the glass slide 3 again;

referring to fig. 2, a round rod 20 which is in axial sliding fit with a moving plate 19 is rotatably mounted on an expansion link of an electric push rod 2 (the round rod 20 and a shaft of the moving plate 19 are in axial sliding fit), the moving plate 19 rotates a half-turn number N and further drives the round plate 48 to synchronously rotate a half-turn number N through a rotating pulley group 21, so that the round rod 20 and the shaft of the moving plate 19 are in axial sliding fit to match with the vertical height adjustment of the round plate 48 so as to meet the effect of different distances between a glass slide 3 and a dropper 6 when chromosome dropping is performed on different cell sap, and the moving plate 19 can transmit power to the round plate 48 no matter where the round plate 48 is located.

Embodiment 3, on the basis of embodiment 2, referring to fig. 9, one end of the rotating shaft 12 extending upward from the loading plate 5 is provided with a one-way pulley 22, the structure of the one-way pulley 22 referring to fig. 7, that is, the one-way pulley 22 and the rotating shaft 12 are rotatably installed, we arrange ratchets 51 on the inner circumferential surface of the one-way pulley 22 at intervals, and rotatably install pawls 50 matching with the ratchets 51 at corresponding positions on the rotating shaft 12, we fix an elastic block 52 abutting against the pawls 50 on the rotating shaft 12, we set the motor 11 to drive the rotating shaft 12 to rotate in the clockwise direction as shown in fig. 9, the cross-sectional view of the one-way pulley 22 in fig. 7, i.e. taken from fig. 9, as shown in fig. 9, when the motor 11 drives the rotating shaft 12 to rotate in the clockwise direction, the rotating shaft 12 further achieves the effect of driving the one-way pulley 22 to rotate through the, further, the extrusion belt 23 is used for driving the extrusion gear 24 to rotate, the extrusion gear 24 rotates and further drives the driving ring 7 to synchronously rotate through an extrusion tooth system 25 meshed with the extrusion gear, arc-shaped plates 26 are integrally arranged on two axial sides of the driving ring 7, and circular truncated cones 27 are integrally arranged at the positions, equal to the arc-shaped plates 26, of the lower ends of the two T-shaped plates 8;

we set the initial position, two arc plates 26 are in the position just contacting with the circular table 27, when two T-shaped plates 8 are still at the initial position (at this time, the dropper 6 does not drop the cellular liquid downwards), the arc plates 26 are synchronously driven to rotate along with the rotation of the driving ring 7, the two T-shaped plates 8 are forced to move towards the direction of approaching each other under the extrusion of the arc plates 26, and then the extrusion of the air bag of the dropper 6 is realized through the extrusion plates 10, so as to extrude the cellular liquid in the dropper 6 outwards, along with the continuous rotation of the driving ring 7, so that when the arc plates 26 are separated from the circular table 27, at this time, the two T-shaped plates 8 move towards the initial position respectively under the action of the expansion springs 9, so as to move to the initial position, the dropper 6 stops dropping the cellular liquid downwards, and then the driving ring 7 continues to rotate until the arc plates 26 are just contacted with the circular table 27 again, the driving ring 7 rotates half a turn (refer to fig. 9, at this time, although the arc plate 26 is just in contact with the circular truncated cone 27 again, the arc plate 26 and the circular truncated cone 27 which are in contact with each other in the previous process are not already in contact with each other, and the arc plate 26 and the circular truncated cone 27 which are in contact with each other in the previous process are in contact with the other circular truncated cone 27 and the arc plate 26, respectively);

it should be noted here that when the initial arc plate 26 is just in contact with the circular truncated cone 27, the intermittent shaft 17 just rotates a certain angle away from the arc groove 18, and with the continuous rotation of the driving ring 7, the dropper 6 immediately drops the cell sap downwards, and at this time, the intermittent shaft 17 rotates along with the intermittent plate 16, when the arc plate 26 is no longer in contact with the circular truncated cone 27, the driving ring 7 rotates a small angle (the contact time between the arc plate 26 and the circular truncated cone 27 is short), and at this time, the intermittent shaft 17 rotates along with the intermittent plate 16, so that when the intermittent shaft 17 rotates to match with the next arc groove 18 again (at this time, the intermittent shaft 17 does not rotate a circle, and the driving ring 7 does not rotate a half-circle), and with the continuous rotation of the intermittent shaft 17, the circular plate 48 is driven to rotate N times, so that the intermittent shaft 17 is again away from the arc groove 18 and rotates a certain angle, at this time, the intermittent shaft 17 rotates once and the driving ring 7 also rotates half a turn (at this time, the two arc-shaped plates 26 integrally provided with the driving ring 7 rotate just to the position just contacting with the circular truncated cone 27), and then the process is consistent with the above actions, so that the transfer of the chromosome drop piece and the slide glass 3 is automatically realized.

Embodiment 4, as shown in fig. 10 with reference to embodiment 1, the driving apparatus includes: a screw 28 rotatably mounted at the upper end of the T-shaped plate 8 and in threaded fit with the extrusion plate 10, a first worm wheel 29 is fixedly sleeved on the screw 28, two first worm wheels 29 at one longitudinal side are matched with a first worm 30 rotatably mounted on the T-shaped plate 8, two first worm wheels 29 at the other longitudinal side are matched with a second worm 31 rotatably mounted on the T-shaped plate 8, and the second worm 31 and the first worm 30 are in axial sliding fit with each other, as shown in fig. 12, when we rotate the carrying cylinder 4, we further drive a third worm 35 to rotate on the carrying plate 5 through a matched inner gear ring 37 and a driving gear 36, we set the inner gear ring 37 coaxially with the carrying cylinder 4, as shown in fig. 9, the position where the third worm 35 is rotatably mounted on the carrying plate 5 is not at the same axial position with the carrying cylinder 4, so that the driving gear 36 fixedly sleeved at the upper end of the third worm 35 is synchronously driven to surround the inner gear ring in the process of rotating the carrying cylinder 4 The gear ring 37 rotates, and the effect of driving the driving gear 36 to rotate (the third worm 35 to rotate) is achieved because the gear ring 37 is fixedly installed on the base 1 and coaxially arranged with the bearing cylinder 4;

referring to fig. 11, the third worm 35 rotates to drive the cylinder 33 rotatably mounted on the object carrying plate 5 through the second worm wheel 34 engaged therewith to rotate, because the cylinder 33 and the first worm 30 are axially slidably mounted to rotate, the first worm 30 is driven to rotate, the first worm 30 rotates to synchronously drive the second worm 31 axially slidably mounted thereto to rotate, and the other first worm 30 is driven to synchronously rotate through the transmission gear 32 engaged therewith (the rotation directions of the two first worms 30 are opposite, because the rotation directions of the two first worms 30 are opposite, one of the first worms 30 drives the two squeezing plates 10 located on the same lateral side to extend outward out of the T-shaped plate 8 through the first worm wheel 29 engaged therewith, and the other first worm 30 drives the two squeezing plates 10 located on the other lateral side to retract inward into the T-shaped plate 8 through the first worm wheel 29 engaged therewith), that is, when we rotate the carrying cylinder 4, we synchronously drive the two squeezing plates 10 located on the same side in the transverse direction to move along the T-shaped plate 8 and the two squeezing plates 10 located on both sides in the transverse direction move in opposite directions, we set that when the carrying cylinder 4 rotates 180 °, we just realize that one set of two squeezing plates 10 located on the same side in the transverse direction slide out of the T-shaped plate 8, so that the other set of two squeezing plates 10 located on the other side in the transverse direction shrink into the T-shaped plate 8, at this time, when the two T-shaped plates 8 move away from or close to each other, the cellular fluid in the dropper 6 located on the standby station is not squeezed out (at this time, the two squeezing plates 10 matched with the dropper 6 located on the standby station shrink into the T-shaped plate 8, as shown in fig. 2);

it should be noted that, referring to fig. 11, the first worm 30 and the corresponding second worm 31 are installed in an axial sliding fit manner, so as to match the longitudinal movement of the two T-shaped plates 8, when we rotate the carrying cylinder 4, we rotate in a clockwise direction as shown in fig. 9, because the internal installation relationship between the one-way pulley 22 and the rotating shaft 12 in fig. 9 is shown in fig. 7, when we rotate the carrying cylinder 4 in a clockwise direction as shown in fig. 7, we synchronously drive the one-way pulley 22 to rotate around the rotating shaft 12 (no relative rotation occurs between the one-way pulley 22 and the carrying plate 5, i.e. the driving ring 7 is not rotated relative to the carrying plate 5), and at this time, the one-way pulley 22 only rotates relative to the rotating shaft 12.

Example 5, on the basis of example 1, referring to fig. 13, we have inserting holes 38 respectively arranged at two lateral sides of the object carrying plate 5, inserting plates 39 are slidably fitted in the inserting holes 38, we fix the dropping pipe 6 on the inserting plates 39 and have positioning holes 40 arranged at two longitudinal sides of the inserting plates 39, initially when the inserting plates 39 are not inserted into the inserting holes 38, the positioning blocks 41 are placed in the inserting holes 38 at the chamfered ends under the action of the positioning springs 42, when we move the inserting plates 39 along the inserting holes 38 arranged on the object carrying plate 5, the inserting plates 39 first enter the inserting holes 38 at the ends and first contact the positioning blocks 41, we perform chamfering on the sides of the positioning blocks 41 facing the inserting plates 39, when the front ends of the inserting plates 39 contact the inclined surfaces of the chamfered parts on the positioning blocks 41, the positioning blocks 41 are forced to move towards the direction of compressing the positioning springs 42, and finally the positioning blocks 41 are completely withdrawn, further, the insert plate 39 is moved along the insertion hole 38, so that when the positioning hole 40 arranged on the insert plate 39 is moved to a position corresponding to the positioning block 41 slidably mounted in the object carrying plate 5, the positioning block 41 is inserted into the positioning hole 40 under the action of the positioning spring 42 and positioning of the insert plate 39 is realized, and further, the effect of fixing the dropper 6 on the object carrying plate 5 is realized, it is set that when the insert plate 39 is moved to a position corresponding to the positioning hole 40, the wall of the insert plate 39 which firstly enters one end of the insertion hole 38 abuts against the bottom wall of the insertion hole 38;

we integrally set a shift lever 49 on the lower end surface of the positioning block 41 and the shift lever 49 penetrates downward through the object carrying plate 5, as shown in fig. 13, when we need to take down the dropper 6, we only need to shift two shift levers 49 integrally connected with the positioning block 41 and make the two shift levers 49 move in the direction away from each other, and then make the two positioning blocks 41 withdraw from the positioning holes 40 corresponding to them, at this time we pull the inserting plate 39 outward to achieve the effect of taking down the dropper 6.

Example 6, on the basis of example 1, referring to fig. 5, we have an annular groove 43 coaxially arranged at the bottom of the carrier cylinder 4 and a plurality of carrier bars 44 rotatably fitted with the annular groove 43 fixed on the base 1 at intervals, i.e., the bottom of the carrier cylinder 4 is rotatably fitted with the carrier bars 44 and the top wall of the annular groove 43 is slidably fitted with the upper end surface of the carrier bars 44, referring to fig. 8, in this embodiment we have three carrier bars 44, two carrier bars 44 are arranged opposite to each other (the two carrier bars 44 are arranged at an interval of 180 °), referring to fig. 6, we have locking posts 46 vertically slidably mounted on the axial top wall of the annular groove 43 at positions corresponding to the two carrier bars 44 arranged opposite to each other, when the carrier cylinder 4 is locked, the locking posts 46 are inserted into the locking holes 47 arranged on the carrier bars 44 under the action of the locking springs 45 to lock the carrier cylinder 4, the lock column 46 and the lock hole 47 which are also matched with each other at the opposite side synchronously lock the carrying cylinder 4, the lock column 46 is inserted into one end of the lock hole 47 to be rounded, as shown in fig. 6, when the carrying cylinder 4 needs to be rotated (the positions of the two droppers 6 are exchanged), only the bottom of the carrying cylinder 4 needs to be held by hands and is rotated forcibly, the lock column 46 is forced to withdraw from the corresponding lock hole 47, when the lock column 46 is completely withdrawn from the lock hole 47, the carrying cylinder 4 is rotated continuously until the lock column 46 is contacted with the two carrying rods 44 at the opposite side again, the carrying cylinder 4 needs to be rotated forcibly to make the lock column 46 pressed by the carrying rods 44, when the lock column 46 moves upwards in the annular groove 43 and is finally withdrawn from the annular groove 43 completely, along with the continuous rotation of the carrying cylinder 4, when the lock column 46 is rotated to be opposite to the lock hole 47 on the carrying rods 44, the locking column 46 is inserted into the locking hole 47 under the action of the locking spring 45, so that the primary locking of the carrier cylinder 4 is realized again;

it should be noted here that when we turn the carriage 4 and want to turn it through 180 °, the speed should be slowed, i.e. when the locking stud 46 will abut against the carriage bar 44, and again, especially when the locking stud 46 abuts against the carriage bar 44 and is completely withdrawn from the annular groove 43, the speed should be slowed, so that the locking post 46 is rotated to just correspond to the locking hole 47 and then inserted downward into the locking hole 47 by the locking spring 45, preferably, a plurality of markers (not shown) are provided around the circular plate 48 at equal intervals, so that when the worker places the slide 3 on the circular plate 48, the glass slide 3 is quickly and accurately placed at the position corresponding to the mark point according to the position of the mark point, and finally the glass slide 3 is also placed on the circular plate 48 at equal intervals for realizing the drip piece work matched with the drip tube 6;

the device can realize the transfer of the dropping liquid and the glass slide 3 without manual intervention, greatly reduces the burden of workers compared with the traditional chromosome dropping work, and in the scheme, when the cell sap in one of the dropping pipes 6 is completely consumed, the other dropping pipe 6 in a standby state can be rotated to a working position, and when the chromosome dropping work is completed in batches, the chromosome dropping efficiency can be greatly improved;
