To: the distance between adjacent two sliding slot is in gradual change shape.
Further, each sliding slot includes that first straight line section, one end of Yu Suoshu first straight line section are described along favouring
Prolong towards the direction far from the first straight line section free end of oblique line section, Yu Suoshu oblique line section that the direction of first straight line section extends
The second straight line section stretched and in the free end of the second straight line section continue to extend towards the direction far from the first straight line section
Third straightway；The second straight line section is parallel with the first straight line section, the third straightway and the first straight line section
In parallel.
Further, the length of the third straightway is greater than the length of the second straight line section.
Further, each adaptation head unit includes that slider body and the sampling head being installed on the slider body pick up
Take head；The positioning pin is installed, each guiding axis runs through each institute on each side of the slider body towards the sliding slot
State slider body.
Further, the through-hole passed through for each guiding axis, any one cunning are offered on each slider body
It is equipped in the through-hole of the part of block body straight in the correspondence through-hole that can protrude into the slider body adjacent thereto
Spool is held, and the correspondence through-hole is stretched out at the both ends of each linear bearing respectively, and each linear bearing is sheathed on described in correspondence
On guiding axis.
Further, the length that each linear bearing stretches out the corresponding through-hole is less than the two of the slider body thickness
/ mono-.
Further, the braced frame is included in when each positioning pin slides into the corresponding sliding slot tail end for taking off
The sampling head gone on each sampling head pick-up head takes off sampling head plate, and described take off offers in sampling head plate for each sampling
Perforative via hole.
Further, the pipettor of the automatic adjustment spacing further includes the push plate for being installed on division drive block two sides
Hook, the braced frame further include linking up with the push plate guide shaft being correspondingly arranged with each push plate and being sheathed on each push plate to lead
Reset spring on axis.
Further, the diameter of each positioning pin is equal with the width of the corresponding sliding slot.
Further, the pipettor of the automatic adjustment spacing further includes outrigger, and the braced frame is slidably mounted on institute
It states on outrigger.
The beneficial effect of the pipettor of automatic adjustment spacing provided by the invention is: compared with prior art, the present invention
Division drive block can be driven to slide on the support frame by driving mechanism, by the way that each positioning pin is protruded into corresponding sliding slot,
Division drive block is during sliding, by the change of each positioning pin position in corresponding sliding slot, it can be achieved that each adapter head list
Movement of the member on guiding axis is arranged between adjacent two sliding slot in gradual change shape, so realize each adaptation head unit it is close with it is remote
From, so that respectively movement with higher consistency of the adaptation head unit on guiding axis, so that between being respectively adapted between head unit
Away from adjusting accuracy height, each sampling precision for being adapted to head unit is high, may replace the driving method of the complexity such as conventional linkage, screw rod,
The volume for greatly reducing pipettor, it is compact-sized small and exquisite, good without accumulated error, processing technology to have many advantages, such as.
