Meanwhile, the second moving driving device 143 is fixedly installed on the moving seat 141, and the linkage plate 144 is connected to the second moving driving device 143, the linkage plate 144 is driven by the second moving driving device 143 to reciprocate along the up-down direction, wherein the moving rod 145 extending upward is fixedly installed on the linkage plate 144, in short, the linkage rod realizes the reciprocating movement along the conveying direction of the conveying channel 120 by the driving of the first moving driving device 142, and the reciprocating movement along the up-down direction is realized by the driving of the second moving driving device 143. In the present embodiment, the first movement driving device 142 and the second movement driving device 143 take a cylinder as an example, and the movement of the moving seat 141 and the linkage plate 144 is driven by the telescopic action of the piston rod; accordingly, as shown in fig. 12, a moving groove 121 for the moving rod 145 to protrude is formed on the bottom plate of the moving passage, and the moving groove 121 extends along the conveying direction of the conveying passage 120, so that the moving rod 145 can move back and forth along the conveying direction of the conveying passage 120 under the driving of the first moving driving device 142; as shown in fig. 8, a plug hole 114 is formed at the bottom of the carrier base 110 to be opposite to the moving rod 145 and into which the moving rod 145 is inserted.

In the using process, after the filter loading device 400 loads the pipetting tip 002 located above the carrier seat 110 with the filter, the carrier seat 110 is transported by the toggle device 130 to move in the direction of the pushing device 500, at this time, the moving rod 145 is driven by the first moving driving device 142 and the second moving driving device 143 to be inserted into the insertion hole 114 located at the bottom of the carrier seat 110, the first moving driving device 142 drives the moving seat 141, so that the carrier seat 110 and the pushing device 500 can mutually push against each other, so as to facilitate the pushing rod 503 of the pushing device 500 to push the filter located in the pipetting tip 002 downwards, and then the first moving driving device 142 drives the moving seat 141 again in the transporting direction of the transporting channel 120, so as to transport the carrier seat 110 which has completed the filter pressing downwards in the downstream direction, and then the moving rod 145 moves downwards under the driving of the second moving driving device 143 to be disengaged from the insertion hole 114 and withdraw under the driving of the first moving driving device 142.

Through the above structure, when the carrying seat 110 is located below the pushing device 500 to wait for the pushing device 500 to push the filter element, the moving rod 145 fixes the relative position of the carrying seat 110 through the first moving driving device 142 and the second moving driving device 143, and makes the relative position correspond to the pushing rod 503, and meanwhile, after the pushing is completed, the moving mechanism 140 can timely convey the carrying seat 110 downward in a certain direction without actions of the toggle device 130, it is worth describing herein that the toggle device 130 conveys the carrying seats 110 by toggling the carrying seats 110, so that the carrying seats 110 are conveyed in the conveying channel 120 under the condition that the carrying seats 110 are mutually attached, in this way, the action process is slow, and the moving of the carrying seats 110 through the moving mechanism 140 is fast.

Further, as shown in fig. 14, a shift mechanism 160 is further disposed above the pipette head transporting device 100, and is located below the pushing device 500 and located at a downstream side of the pushing device 500 along a transporting direction that the transporting sleeve can reach, so as to block the loading base 110 that is moved to a position below the pushing device 500 by the toggle device 130, and prevent the loading base 110 from moving out of the range of the pushing device 500, which is inconvenient for compressing the filter cartridge on the loading base 110. The shift mechanism 160 includes a shift cylinder 161 and a shift member 162, wherein a piston rod of the shift cylinder 161 extends toward the conveying passage 120, and the shift member 162 is connected to the piston rod of the shift cylinder 161 and driven by the same to extend toward the conveying passage 120 and project into the conveying passage 120, so as to block the carrier seat 110 conveyed below the pressing device 500.

In the using process, after the carrier seat 110 is conveyed to the lower part of the push-down device 500 by the toggle device 130, the shift cylinder 161 drives the shift member 162 to enter into the conveying channel 120, so as to block the carrier seat 110 and prevent it from flowing out of the range of the push-down device 500, after the carrier seat 110 is blocked by the shift member 162, the movable seat 141 is driven by the first movable driving device 142 to move towards the bottom of the carrier seat 110, and the movable rod 145 is driven by the second movable driving device 143 to lift upwards and insert into the insertion hole 114 of the carrier seat 110, and then, the carrier seat 110 is driven by the first movable driving device 142 to move within the conveying channel 120, so that the liquid-transferring tip 002 on the carrier seat 110 and the push-down rod 503 of the push-down device 500 mutually align with each other, thereby facilitating the push-down rod 503 to press down the filter core in the liquid-transferring tip 002.

Various other modifications and alterations of the disclosed structure and principles may occur to those skilled in the art, and all such modifications and alterations are intended to be included within the scope of the present invention.
