Freely be arranged, when user pulls the free end of deduction, can by third connecting rod 509 drive fourth link 510 end to
On lift, while scraper plate 503 being driven to move up.
As shown in FIG. 8 and 9, scraper plate 503 is located at the back side of screen tray 4, and the back side of screen tray 4 and the both ends for being located at scraper plate 503
A guiding skewback 506 is respectively provided at position, when scraper plate 503 is driven and Xiang Shangyi on guiding skewback 506 by fourth link 510
When dynamic, by the effect of guiding surface on guiding skewback 506, the displacement of platform 402 can be generated far from blanking channel 403 and shelve,
When scraper plate 503 reaches the top of guiding skewback 506, scraper plate 503, which is placed exactly in, shelves the outside of platform 402 in order to push rifle
First 1 falls into blanking channel 403.Scraper plate 503 will extend over guiding skewback 506 and quickly push pipette tips 1 flat from shelving when continuing to move up
Platform 402 is moved in blanking channel 403, and is fallen from blanking channel 403.
Also it is cased with the first guide sleeve 513 and the second guide sleeve 514 on scraper plate 503, scraper plate 503 passes through the first guide sleeve 513 and can be with
Horizontal direction is moved forward and backward in the guide sleeve, but cannot be moved freely in the up-down direction, and scraper plate 503 passes through the second guide sleeve 514
And it can be moved up and down in the guide sleeve, but cannot be moved forward and backward in the horizontal direction.The end of fourth link 510 is movably hinged
On the first guide sleeve 513, the first force application part is connected on the first guide sleeve 513, wherein the both ends of the first force application part connect respectively
It connects on the lower part of guide sleeve and screen tray 4 to generate the active force for pulling guide sleeve and scraper plate 503 to move down, can also be construed to make
The active force of upper oral part of the scraper plate 503 far from blanking channel 403 and its close infraoral, in the present embodiment, first force
Component is tension spring.The both ends of second force application part are connected on the side and screen tray 4 of the second guide sleeve 514, are pulled with generating
Second guide sleeve 514 and scraper plate 503 are close to the active force of screen tray 4 inwardly, also may be interpreted as the work for making it be close to blanking channel 403
Firmly, in the present embodiment, the second force application part is also tension spring.
As shown in FIG. 8 and 9, the top for being oriented to skewback 506 is equipped with the interconnection passed through for the end of scraper plate 503, so that
Scraper plate 503 cross guiding skewback 506 after can under the action of the second force application part from far from blanking channel 403 position
Quickly close to blanking channel 403, after scraper plate 503 is close to blanking channel 403, due to being provided with confession in guiding 506 behind of skewback
The vertical passageway that scraper plate 503 passes through, under the action of the first force application part, scraper plate 503 is moved down from vertical passageway, by perpendicular
Effect to the bottom of the channel limiting device 507, scraper plate 503 turn again to the position of the lower section of guiding skewback 506.It needs to illustrate
It is that during scraper plate 503 is moved up along the slope surface of guiding skewback 506, the first force application part and the second force application part are same
When accumulation of energy, generate the pulling force downward to scraper plate 503 and pulling force inwardly respectively.
As shown in figure 9, the scraper plate 503 is connect by slide construction with pilot pin 605, the slide construction includes sliding block
And sliding slot, the sliding slot perpendicular to pilot pin 605 length direction so that sliding block be only capable of perpendicular to pilot pin 605 direction shifting
It moves and cannot be moved in the direction for being parallel to pilot pin 605.The sliding block and sliding slot are separately positioned on scraper plate 503, pilot pin 605
In one and another on, in the present embodiment, sliding block be located on scraper plate 503 and the two be integrally formed, sliding slot be located at positioning
On the convex block extended on needle 605 to side, the setting of this kind of structure generates card during can preventing pilot pin 605 from moving up and down
Extremely.
