[0073] Referring to Figures 1 to 10 The utility model discloses an embodiment provides a kind of test carrier clamping device, test carrier clamping device includes top cap 100, clamping block assembly 200, at least one guide slide assembly 500 and dial block 450, two clamping block assembly 200 are located in the opposite ends of top cap 100, at least one of two clamping block assembly 200 can be moved relative to top cap 100 to adjust to test carrier clamping;Guide slide assembly 500 is slidably connected in top cap 100, for driving movable clamping block assembly 200;Dial block 450 is connected to one guide slide assembly 500;Wherein, movable clamping block assembly 200 is structured with drive sliding slot 231, one end of guide slide assembly 500 is slidably arranged in drive sliding slot 231, dial block 450 can be operatively guided guide slide assembly 500 relative to top cap 100 moves, to drive clamping block assembly 200 relative to top cap 100 moves;The line between the two end points of drive sliding slot 231 is included with the side of top cap 100 Angle.

[0074] The technical scheme provides a test carrier clamping device, which is applied to an oscillation equipment 800 and is used for clamping a test carrier, for example, a microtiter plate 900. The two clamping block assemblies 200 are arranged at opposite ends of the top cover 100, and at least one of the two clamping block assemblies 200 is movable relative to the top cover 100, so that the distance between the two clamping block assemblies 200 is adjusted, so that the clamping block assemblies 200 clamp or release the test carrier. The guide sliding assembly 500 is slidingly connected to the top cover 100, so that the at least one clamping block assembly 200 is moved relative to the top cover 100 through the guide sliding assembly 500. The driving sliding groove 231 is arranged on the clamping block assembly 200 movable relative to the top cover 100, and the push block 450 is connected to the guide sliding assembly 500. When the push block 450 is operatively moved, the push block 450 can drive the guide sliding assembly 500 to move relative to the top cover 100. Since the guide sliding assembly 500 extends into the driving sliding groove 231, the guide sliding assembly 500 can act on the side wall of the driving sliding groove 231, so as to drive the clamping block assembly 200 to move relative to the top cover 100. In the application, the at least one clamping block assembly 200 is movable relative to the top cover 100, so that the relative distance between the two clamping block assemblies 200 can be adjusted, so as to clamp or release the test carrier. The extension direction of the driving sliding groove 231 is arranged in the form of an angle with the side of the top cover 100, so that when the driving push block 450 moves relative to the top cover 100, the extension direction of the driving sliding groove 431 changes relative to the moving direction of the clamping block assembly 200 and the push block 450, so that the guide sliding assembly 500 drives the clamping block assembly 200 to move in a direction perpendicular to the side of the top cover 100, so as to realize the mutual approach or separation of the two clamping block assemblies 200, and then clamp or release the test carrier. Through the above structure, the clamping and dismounting of the microtiter plate 900 are more convenient, so as to improve the work efficiency.

[0075] In the embodiment, the top cover 100 is a rectangular structure, and the two clamping block assemblies 200 are arranged at opposite ends along the length direction of the top cover 100. In another embodiment, the two clamping block assemblies 200 can also be arranged at opposite ends along the width direction of the top cover 100. One of the two clamping block assemblies 200 can be movable relative to the top cover 100, and the other one is fixed. Alternatively, both of the two clamping block assemblies 200 can be movable relative to the top cover 100.

[0076] When one of the clamping block assemblies 200 moves relative to the top cover 100, only one guide sliding assembly 500 is needed, and the push block 450 is connected with the guide sliding assembly 500, and the guide sliding assembly 500 is manually driven relative to the top cover 100 through the push block 450, so as to drive the clamping block assembly 200 to move relative to the top cover 100. Correspondingly, only the driving sliding groove 231 is arranged on one of the clamping block assemblies 200, and the guide sliding assembly 500 is slidably arranged in the driving sliding groove 231, so that the clamping block assembly 200 is driven to move relative to the top cover 100 by the guide sliding assembly 500 acting on the groove wall of the driving sliding groove 231.

[0077] It can be understood that the push block 450 can be an integral structure with the guide sliding assembly 500, and the push block 450 is exposed to the side edge of the top cover 100 as an extension of the guide sliding assembly 500, so as to manually drive the push block 450 to move relative to the top cover 100 by the operator. In another embodiment, the push block 450 and the guide sliding assembly 500 can be indirectly connected through other components.

[0078] When both of the clamping block assemblies 200 can move relative to the top cover 100, two guide sliding assemblies 500 are needed, and the driving sliding groove 231 is arranged on each of the clamping block assemblies 200, and the guide sliding assembly 500 is correspondingly slidably arranged in the driving sliding groove 231, so as to drive the clamping block assembly 200 to move relative to the top cover 100.

[0079] Specifically, the test vehicle clamping device further comprises a transmission mechanism 300 and at least one actuating assembly 400. The transmission mechanism 300 is drivingly connected to the top cover 100; the actuating assembly 400 is fixedly connected to the transmission mechanism 300, wherein the guide sliding assembly 500 is fixedly connected to the actuating assembly 400, and the push block 450 is connected to one of the actuating assemblies 400, and the push block 450 is used to operatively drive the actuating assembly 400 to move relative to the top cover 100, so as to drive the transmission mechanism 300 to move relative to the top cover 100.

[0080] By drivingly connecting the transmission mechanism 300 with the top cover 100, fixing the actuating assembly 400 to the transmission mechanism 300, and connecting the push block 450 with one of the actuating assemblies 400, the actuating assembly 400 is moved relative to the top cover 100 by manually pushing the push block 450, and since the actuating assembly 400 is fixedly connected to the transmission mechanism 300, the transmission mechanism 300 can be moved relative to the top cover 100, and simultaneously drives the other actuating assembly 400 to move relative to the top cover 100. Since the guide sliding assembly 500 is fixedly connected to the actuating assembly 400, the guide sliding assembly 500 is driven to move relative to the clamping block assembly 200 by the movement of the actuating assembly 400 relative to the top cover 100.

[0081] In the embodiment, the knob 450 is connected to one of the actuating assemblies 400, and the knob 450 is moved along the side of the top cover 100 by manually pushing the knob 450, and the guide sliding assembly 500 connected to the actuating assembly 400 drives the clamping block assembly 200 to move perpendicularly to the moving direction of the knob 450. For example, when the knob 450 is arranged on the side of the top cover 100 at the lengthwise two ends, the knob 450 is moved along the width direction of the top cover 100 by pushing the knob 450, and correspondingly, the actuating assembly 400 drives the guide sliding assembly 500 to move along the width direction of the top cover 100, and then the guide sliding assembly 500 drives the clamping block assembly 200 to move along the length direction of the top cover 100.

[0082] In one of the embodiments, the top cover 100 is provided with a guide sliding groove 121, and the guide sliding assembly 500 comprises a connecting end and a driving end, the connecting end of the guide sliding assembly 500 is connected to the knob 450, and the driving end of the guide sliding assembly 500 extends into the driving sliding groove 231 through the guide sliding groove 121; the extension direction of the driving sliding groove 231 is at an angle with the extension direction of the guide sliding groove 121, and the guide sliding assembly 500 is operable to drive the knob to move relative to the top cover 100, the knob drives the guide sliding assembly 500 to move along the guide sliding groove 121, and the guide sliding assembly 500 drives the clamping block assembly 200 to move along the direction perpendicular to the extension direction of the guide sliding groove 121.

[0083] When the knob 450 is operable to move, the transmission mechanism 300 is driven by the actuating assembly 400 connected to the knob 450 to move relative to the top cover 100, and then the other actuating assembly 400 fixed on the transmission mechanism 300 moves relative to the top cover 100. By correspondingly arranging the guide sliding assembly 500 on the actuating assembly 400, the guide sliding assembly 500 is operable to move relative to the top cover 100 when the actuating assembly moves relative to the top cover 100. Since the driving sliding groove 231 is arranged on the clamping block assembly 200, and the guide sliding groove 121 is arranged on the top cover 100, the driving end of the guide sliding assembly 500 extends into the driving sliding groove 231 through the guide sliding groove 121. When the knob 450 is operable to move, the transmission mechanism 300 moves relative to the top cover 100, and then the other actuating assembly 400 fixed on the transmission mechanism 300 moves. When the actuating assembly 400 moves relative to the top cover 100, the guide sliding assembly 500 is driven to move along the guide sliding groove 121, and since the guide sliding assembly 500 extends into the driving sliding groove 231, the guide sliding assembly 500 can act on the side wall of the driving sliding groove 231 to drive the clamping block assembly 200 to move relative to the top cover 100.

[0084] It should be noted that, in this embodiment, the guide groove 121 can be a through groove directly extending through the top cover 100. The guide slide assembly 500 is fixedly connected to the actuation assembly 400, and the actuation assembly 400 slides within the guide groove 121 and is connected to the transmission mechanism 300. In another embodiment, the guide slide assembly 500 can be a recessed groove provided on the top cover 100, and the actuation assembly 400 slides within the recessed groove. A through straight groove is provided on the bottom of the recessed groove, and the guide slide assembly 500 is fixedly connected to the actuation assembly 400 and extends through the straight groove into the drive groove 231.

[0085] In some embodiments, the extending direction of the drive slide 231 is set at an angle to the extending direction of the guide slide 121. This allows the drive actuation assembly 400 to move relative to the top cover 100, changing the directions of the guide slide 121 and the drive slide 231 to alter the moving directions of the clamping block assembly 200 and the actuation assembly 400. This causes the guide slide assembly 500 to drive the clamping block assembly 200 to move along a direction perpendicular to the guide slide 121, thereby allowing the two clamping block assemblies 200 to move closer or further apart, thus clamping or releasing the test fixture. This structure facilitates the clamping and disassembly of the micro-titer plate 900, thereby improving operational efficiency.

[0086] It should be noted that in this embodiment, the extension direction of the guide groove 121 is parallel to the side of the top cover 100. In other words, the extension direction of the guide groove 121 is along the length or width direction of the top cover 100. By setting the drive groove 231 at an angle to the guide groove 121, the movement of the actuation component 400 along the guide groove drives the movement of the guide slide component 500. Because the extension directions of the guide groove 121 and the drive groove 231 are different, the clamping block component 200 moves in a direction perpendicular to the guide groove 121.

[0087] Furthermore, the top cover 100 is provided with a receiving cavity, and the clamping block assembly 200 is provided on the side of the top cover 100 away from the receiving cavity; the transmission mechanism 300 and the actuation assembly 400 are provided in the receiving cavity.

[0088] like Figures 5 to 7 As shown, specifically, the clamping block assembly 200 includes a clamping block seat 210, a clamping block 220, and a guide block 230. The clamping block seat 210 is slidably connected to one end of the top cover 100; the clamping block 220 is fixedly connected to one side of the clamping block seat 210; the guide block 230 is fixedly connected to the side of the clamping block seat 210 away from the clamping block 220, and a drive groove 231 is provided on the guide block 230.

[0089] In the embodiment, the clamp block seat 210 is used to support the clamp block 220 and to establish a bridge for the linkage of the clamp block 220 and the guide block 230. Specifically, the clamp block seat 210 is slidingly connected with the top cover 100, and the clamp block 220 is fixedly connected with the clamp block seat 210, so that the clamp block seat 210 can move relative to the top cover 100, thereby driving the clamp block 220 to move relative to the top cover 100 to achieve clamping and loosening of the test vehicle. By arranging the guide block 230 on the clamp block seat 210 and arranging the driving sliding groove 231 on the guide block 230, one end of the guide sliding assembly 500 passes through the guide sliding groove 121 on the top cover 100 and extends into the driving sliding groove 231 on the guide block 230. When the actuating assembly 400 is manually operable relative to the top cover 100, the guide sliding assembly 500 can be driven to move relative to the top cover 100, and the guide sliding assembly 500 can act on the groove wall of the driving sliding groove 231, thereby pushing the guide block 230 to move relative to the top cover 100, and further pushing the clamp block seat 210 to move relative to the top cover 100 to drive the clamp block 220 to move relative to the top cover 100 through the clamp block seat 210.

[0090] It can be understood that the structure of the driving sliding groove 231 is not limited, which can be an arc-shaped groove or a straight groove. As a preferred embodiment, as shown in Figure 7 the driving sliding groove 231 is arranged as a straight groove, and an acute angle is formed between the extension direction of the driving sliding groove 231 and the guide sliding groove 121.

[0091] As shown in Figure 7 further, the clamp block assembly 200 further comprises a guide column 240 and a guide sleeve 250, and at least one guide column 240 is fixedly connected to each of the opposite ends of the clamp block seat 210; the guide sleeve 250 is fixedly connected to the top cover 100 and slidingly sleeved on the guide column 240.

[0092] By fixing at least one guide column 240 to each of the opposite ends of the clamp block seat 210, fixing the guide sleeve 250 on the top cover 100, and slidingly sleeving the guide sleeve 250 on the guide column 240, the movement of the clamp block seat 210 relative to the top cover 100 is guided by the cooperation of the guide column 240 and the guide sleeve 250, so that the movement of the clamp block seat 210 relative to the top cover 100 is more stable.

[0093] It can be understood that for the sliding fit of the guide column 240 and the guide sleeve 250, limiting structures can be arranged at the ends of the guide sleeve 250 and the guide column 240 to prevent the two from being separated. In another embodiment, the limiting structures can also not be arranged, and the movement stroke of the clamping block seat 210 is limited by the driving sliding groove 231 on the guide block 230. Specifically, the movement stroke of the clamping block seat 210 is the projection length of the driving sliding groove 231 in the movement direction of the clamping block seat 210. In the present embodiment, the guide sleeve 250 is a circular guide sleeve 250, and the guide column 240 is a cylindrical column. With this structure, the structure is simple and easy to process. In another embodiment, the guide sleeve 250 can be arranged as a square or rectangular guide sleeve 250, and the guide column 240 can be arranged in a structure matching the inner hole of the guide sleeve 250.

[0094] As shown in Figure 6 one of the embodiments, the clamping block 220 is configured with a notch 221 penetrating along the thickness direction of the clamping block 220. The two opposite side walls of the notch 221 are arranged to be inclined, and the opening of the notch 221 gradually decreases from the end facing the top cover 100 to the end away from the top cover 100.

[0095] By arranging the notch 221 on the clamping block 220, the side edges of the microtiter plate 900 are limited by the side walls of the notch 221, and the ends of the microtiter plate 900 are clamped by the bottom wall of the notch 221, thereby improving the stability of the clamping of the microtiter plate 900 by the clamping block 220. In the present embodiment, the two opposite side walls of the notch 221 are arranged in an inclined form, and the opening of the notch 221 gradually decreases from the end facing the top cover 100 to the end away from the top cover 100, so as to facilitate guiding through the inclined surface of the opening of the notch 221 when clamping the microtiter plate by the clamping block 220, thereby facilitating clamping of the microtiter plate by the clamping block 220.

[0096] As shown in Figure 6 and Figure 7 further, the edge between the side surface of the clamping block 220 facing the test carrier and the side surface facing the clamping block seat 210 is arranged as an inclined chamfer 222. The edge between the side surface of the clamping block 220 facing the top cover 100 and the side surface facing the clamping block seat 210 is arranged as an inclined chamfer 222, so that the inclined chamfer 222 abuts against the microtiter plate 900, thereby limiting the microtiter plate 900 in the thickness direction, to further improve the stability of the clamping of the microtiter plate 900 by the clamping block 220.

[0097] It can be understood that in the embodiment, the distance between the inclined surface formed by the chamfer 222 of the edge between the side of the one end of the clamp block 220 facing the test carrier and the side facing the clamp block seat 210 and the clamp block seat 210 should be greater than the thickness of the microtiter plate 900, so that the chamfer 222 can press against the microtiter plate 900.

[0098] In one of the embodiments, the clamp block assembly 200 includes at least one clamp block 220, which is arranged at one end of the clamp block seat 210 and on the corner of the top cover 100, and the clamp blocks 220 in the two clamp block assemblies 200 occupy at least two diagonally opposite corners of the top cover 100.

[0099] The clamp block 220 is arranged on the corner of the top cover 100, and the clamp blocks 220 on the two opposite clamp block assemblies 200 are diagonally opposite. In this way, the clamp block 220 clamps two diagonally opposite corners or four diagonally opposite corners of the test carrier, and the other parts are exposed, so that the test carrier can be clamped by the clamping jaw and then carried.

[0100] In the embodiment, the specific structure of the clamp block 220 is not limited, which can be a corner structure with a concave notch matching the corner of the test carrier, or a structure in which two cylindrical clamping jaws are arranged at intervals on the clamp block seat.

[0101] As shown in Figure 7 In one of the embodiments, the test carrier clamping device further includes a first elastic member 610, at least one first elastic member 610 is arranged at each of the opposite ends of the guide block 230, one end of the first elastic member 610 is fixedly connected to the clamp block seat 210, and the other end of the first elastic member 610 is fixedly connected to the top cover 100.

[0102] Specifically, the first elastic member 610 is a spring. By arranging at least one first elastic member 610 at each of the opposite ends of the guide block 230, and fixing one end of the first elastic member 610 to the clamp block seat 210 and the other end to the top cover 100, when the clamp block seat 210 moves relative to the top cover 100, so that the two clamp blocks 220 move in the direction away from each other to the open state of the two clamp blocks 220, the spring is stretched. When the force applied to the actuating assembly 400 is removed, the clamp block seat 210 moves relative to the top cover 100 under the elastic force of the spring, so that the two clamp blocks 220 move in the direction close to each other to achieve clamping of the microtiter plate 900.

[0103] Specifically, the top cover 100 includes a cover plate 110 and a support plate 120, a receiving cavity is arranged on the cover plate 110, and the clamp block seat 210 is movably arranged on the cover plate 110; one end of the spring is fixedly connected to the edge of the support plate facing the clamp block seat 210, the other end of the spring is fixedly connected to the clamp block seat, and the spring is parallel to the guide column.

[0104] In one embodiment, the test vehicle clamping device further includes a second elastic element 620, which is disposed within the guide groove 121. Both ends of the second elastic element 620 are connected to the actuation assembly 400 and the top cover 100, respectively. Specifically, the second elastic element 620 is a spring. By disposing of the second elastic element 620 within the guide groove 121, with one end fixedly connected to the top cover 100 and the other end connected to the actuation assembly 400, the second elastic element 620 provides elastic force for the return of the actuation assembly 400.

[0105] like Figure 3 and Figure 4 As shown, in one embodiment, the transmission mechanism 300 includes an idler shaft 310, an idler wheel 320, and a timing belt 330. An idler shaft 310 is provided at each of the four corners of the top cover 100, and the idler shaft 310 is throttle connected to the top cover 100. The idler wheel 320 is throttle connected to the idler shaft 310. The timing belt 330 is stretched on the four idler wheels 320. The actuation component 400 is fixedly connected to the timing belt 330.

[0106] By providing an idler shaft 310 at each of the four corners of the top cover 100 and connecting the idler shaft 310 to the top cover 100, and by connecting the idler wheel 320 to the idler shaft 310, the idler shaft 310 can be driven to rotate relative to the top cover 100 when the synchronous belt 330 stretched between the four idler wheels 320 moves. Specifically, the idler shaft 310 can be fixedly connected to the top cover 100, and the idler wheel 320 can be rotatably connected to the idler shaft 310, allowing the idler wheel 320 to rotate relative to the top cover 100. In another embodiment, the idler shaft 310 can be rotatably connected to the top cover 100, and the idler wheel 320 can be fixedly connected to the idler shaft 310, so that the rotation of the idler shaft 310 relative to the top cover achieves the rotation of the idler wheel 320 relative to the top cover 100.

[0107] When the actuation component 400 is fixedly connected to the timing belt 330, and one of the actuation components 400 is manually operated to move relative to the top cover 100, the timing belt 330 moves relative to the top cover 100, thereby driving the actuation component 400 fixed on the timing belt 330 to move relative to the top cover 100, so that the two clamping blocks 210 can move relative to the top cover 100 at the same time, so as to achieve the clamping or releasing of the clamping block 220.

[0108] Specifically, each idler 320 is provided with a plurality of teeth extending along the axial direction of the idler 320, and the inner side of the synchronous belt 330 is provided with a plurality of tooth grooves extending along the width direction of the synchronous belt 330, the tooth grooves being engaged with the teeth to achieve the transmission between the synchronous belt 330 and the idler 320. The idler shaft 310 is rotatably connected to the top cover 100 through a bearing. In some embodiments, the top cover 100 includes a cover plate 110 and a support plate 120, a receiving cavity is arranged on the cover plate 110, and the clamp block seat 210 is movably arranged on the cover plate 110; the support plate 120 is arranged in the receiving cavity, and the idler shaft 310 is rotatably connected to the support plate 120. The idler 320 and the synchronous belt 330 are arranged on the side of the support plate 120 away from the clamp block seat 210. The cover plate 110 and the support plate 120 are fixedly connected, and the support plate 120 is configured as a plate-shaped structure with a through hole arranged in the middle, so as to reduce the weight of the top cover 100.

[0109] As shown in Figure 3 , Figure 4 , Figure 7 and Figure 8 , in one embodiment, one end of the dial 450 is fixedly connected to the actuating assembly 400, and the other end of the dial 450 is exposed on the end surface of the top cover 100 through the guide groove 111 on the side of the top cover 100, and the dial 450 is operable to move along the guide groove 111.

[0110] The actuating assembly 400 is used to establish the connection between the synchronous belt 330 and the dial 450, and the dial 450 is used to manually apply force, so as to achieve the movement of the synchronous belt 330 relative to the top cover 100. It should be noted that in the present embodiment, the dial 450 is arranged on one of the actuating assemblies 400, and the dial 450 can not be arranged on the other actuating assembly 400. When manually operated, only the dial 450 needs to be manually operated, and the actuating assembly 400 provided with the dial 450 can be driven to move relative to the top cover 100, so as to drive the clamp block seat 210 to move relative to the top cover 100.

[0111] In one embodiment, the actuating assembly 400 includes a sliding seat 410, a fixed seat 420, and a fixed plate 430, the sliding seat 410 is at least partially slidably arranged in the guide sliding groove; the fixed seat 420 is fixedly connected to the sliding seat 410, one end of the fixed seat 420 is provided with an avoiding groove 421 extending along the side of the top cover, the synchronous belt passes through the avoiding groove 421, and the fixed seat 420 is further provided with a mounting gap in communication with the avoiding groove 421; one end of the fixed plate 430 is arranged in the mounting gap and fixedly connected to the fixed seat 420, and the synchronous belt is clamped between the fixed seat 420 and the fixed plate 430; wherein one end of the dial is fixedly connected to the fixed seat 420.

[0112] The sliding seat 410 is capable of sliding along the guide sliding groove by being at least partially slid in the guide sliding groove. The sliding seat 410 is capable of driving the fixed seat 420 to slide relative to the guide sliding groove by being fixedly connected to the sliding seat 410. The synchronous belt is capable of being clamped between the fixed plate 430 and the fixed seat 420 by being set in the avoiding groove 421 on the fixed seat 420, and by being set in the mounting gap on the fixed seat 420 which is in communication with the avoiding groove 421, so as to realize the fixed connection between the actuating assembly 400 and the synchronous belt. The end of the poking block is fixedly connected to the fixed seat 420, so that the poking block is capable of driving the fixed seat 420 to slide relative to the top cover when the poking block is poked.

[0113] As shown in Figure 8 Further, the support plate 120 is provided with a guide sliding groove 121 which penetrates along the thickness direction of the support plate 120 and extends along the width direction of the support plate 120 at one end along the length direction. The actuating assembly 400 comprises a sliding seat 410, a fixed seat 420 and a fixed plate 430. The sliding seat 410 is arranged on the side of the support plate 120 which is away from the synchronous belt 330. The fixed seat 420 and the fixed plate 430 are arranged on the side of the support plate 120 which is towards the synchronous belt 330. The sliding seat 410 is provided with a guide protrusion which matches the groove width of the guide sliding groove 121. The end of the poking block 450 is pressed between the guide protrusion and the fixed seat 420. The fixed seat 420 is fixedly connected to the guide protrusion. The fixed seat 420 is provided with an avoiding groove 421 through which the synchronous belt 330 passes. The end of the fixed plate 430 which is towards the synchronous belt 330 is provided with a tooth which engages with the tooth groove on the synchronous belt 330. The fixed plate 430 is fixedly connected to the fixed seat 420. The fixed connection between the fixed seat 420, the fixed plate 430 and the synchronous belt 330 is realized by the clamping force between the fixed plate 430 and the fixed seat 420, so as to realize the fixed connection between the whole actuating assembly and the synchronous belt 330. The guide groove 111 is arranged on the side edge of the cover plate 110. The end of the poking block 450 which is away from the fixed seat 420 extends out of the guide groove 111 and is exposed outside the top cover 100. The length of the guide groove 111 is equivalent to or smaller than the length of the guide sliding groove 121. Specifically, the poking block 450 is configured as a block structure. A protruding rod extends out of one end of the block structure. The block structure is clamped between the fixed seat 420 and the sliding seat 410. The protruding rod is exposed outside the top cover 100 from the guide groove 111. A mounting plate 440 is further arranged between the block structure which is a part of the poking block 450 and the sliding seat 410. The mounting plate 440 is provided with a lug at one end along the extension direction of the guide sliding groove 121. One end of the guide sliding assembly 500 is fixedly connected to the lug.

[0114] As shown in Figure 7And Figure 8 As shown in the drawings, in one embodiment, the guide sliding assembly 500 includes a fixed rod 510 and a guide sliding rod 520, one end of the fixed rod 510 is fixedly connected to the actuating assembly as a connecting end, and the rod body of the fixed rod 510 is slidably arranged in the guide sliding groove 121; the guide sliding rod 520 is drivingly connected to the other end of the fixed rod 510, and the end of the guide sliding rod 520 away from the fixed rod is slidably arranged in the driving sliding groove 231 as a driving end.

[0115] Specifically, the connecting end of the fixed rod 510 is fixedly connected with the lug on the mounting plate 440, and the fixed rod 510 is slidably arranged in the guide sliding groove 121. By drivingly connecting the guide sliding rod 520 with the fixed rod 510, the friction between the guide sliding rod 520 and the driving sliding groove 231 is reduced, so that when the guide sliding rod 520 exerts force on the side wall of the driving sliding groove 231 to drive the guide block 230 to move relative to the top cover 100, the friction between the guide sliding rod 520 and the groove wall of the driving sliding groove 231 is reduced, thereby making the movement of the guide block 230 more smooth, and also facilitating the reduction of wear on the guide sliding rod 520. It can be understood that the two ends of the clamping block seat 210 connected to the cover plate 110 are provided with mounting grooves, the clamping block seat 210 is mounted in the mounting grooves, the top surface of the clamping block seat 210 is substantially flush with the top surface of the cover plate 110, and the clamping block 220 protrudes from the top surface of the cover plate 110. In order to enhance the guiding performance of the clamping block seat 210 and the top cover 100, a semicircular groove is provided on the top surface of the top cover 100 in the mounting groove, and a semicircular guide protrusion is correspondingly provided at the two ends of the clamping block seat 210, which cooperates with the groove. In this embodiment, the clamping block seat 210 is U-shaped, and the shape of the mounting groove corresponds to the shape of the clamping block seat 210.

[0116] Further, through grooves are provided on the cover plate 110 at positions corresponding to the mounting grooves, and the guide block 230 is arranged in the receiving cavity of the cover plate 110 through the through grooves, so that the guide sliding rod 520 can extend into the driving sliding groove 231 on the guide block 230.

[0117] As Figure 9 And Figure 10 As shown in the drawings, in one embodiment, the test carrier clamping device further includes a driving mechanism 700, the driving mechanism 700 includes a driving motor 710 and a connecting rod sliding assembly 720, and the motor base of the driving motor 710 is fixedly connected to the base 810; one end of the connecting rod sliding assembly 720 is connected with the output shaft of the driving motor 710, and the other end of the connecting rod sliding assembly 720 is connected with the actuating assembly to push the actuating assembly 400 to move relative to the top cover 100.

[0118] In this embodiment, the base 810 is the base 810 of the oscillation device 800, and the top cover 100 is placed on the base 810. The motor mount of the drive motor 710 is fixedly connected to the base 810, and the connecting rod sliding assembly 720 is connected to the output shaft of the drive motor 710, so that the output shaft of the drive motor 710 drives the connecting rod sliding assembly 720 to move. The connecting rod sliding assembly 720 is linked with the actuation assembly 400 to achieve movement of the actuation assembly 400 relative to the top cover 100, thereby driving the synchronous belt 330 to move relative to the top cover 100.

[0119] In one embodiment, the linkage sliding assembly 720 includes a first link 721, a second link 722, a slider 723, and a paddle 724. One end of the first link 721 is connected to the output shaft of the drive motor 710; one end of the second link 722 is hinged to the other end of the first link 721; one end of the slider 723 is hinged to the second link 722, and the slider 723 slides in a guide groove on the base 810; one end of the paddle 724 is fixedly connected to the slider 723, and the other end is bent and abuts against one end of the actuation assembly 400.

[0120] By connecting the first link 721 to the output shaft of the drive motor 710, the rotation of the output shaft of the drive motor 710 drives the first link 721 to rotate. Since one end of the second link 722 is hinged to the end of the first link 721 opposite to the output shaft, the first link 721 can drive the second link 722 to rotate. The end of the second link 722 opposite to the first link 721 is hinged to the slider 723. Since the slider 723 slides in the guide groove 811 on the base 810, the slider 723 can only move along the extension direction of the guide groove 811. Therefore, the second link 722 can only pull the slider 723 to move along the guide groove 811. Since a lever 724 is connected to the slider 723, one end of the lever 724 is bent and can block one end of the actuation component 400. Thus, during the movement of the slider 723 relative to the guide groove 811, the lever 724 can drive the actuation component 400 to move relative to the top cover 100, thereby driving the synchronous belt 330 to move.

[0121] like Figure 9 As shown, an oscillation device includes the aforementioned test fixture clamping device. Specifically, a rotating shaft is provided on the base of the oscillation device, and a top cover is fixedly connected to the rotating shaft. The top cover rotates relative to the base under the drive of the rotating shaft. The micro-titer plate is clamped on the top cover by the test fixture clamping device, thereby facilitating the micro-titer plate holder to rotate in a circular motion relative to the base as the rotating shaft drives the top cover. By applying the aforementioned test fixture clamping device to the oscillation device, the clamping and disassembly of the micro-titer plate becomes more convenient, thereby improving operational efficiency.

[0122] Any combination of the technical features in the above-described embodiments can be made, and for the sake of brevity, not all possible combinations are described, however, as long as the combination of the technical features does not exist in contradiction, it shall be considered as the scope of the description.

[0123] The above-described embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but it cannot be understood as the limitation of the utility model patent scope. It should be pointed out that for ordinary skilled person in the art, under the premise of not departing from the utility model concept, a number of modifications and improvements can be made, which all belong to the protection scope of the utility model.
