It fills in hole；An arc installation position is additionally provided on the leading flank of the clamping block, the arc installation position connects the clamping block
Top surface and bottom surface, the pipettor are inserted in the arc installation position.
In above-mentioned technical proposal, the spacer pin is two, and two limit holes are additionally provided on the left of the sliding block leading flank,
Including upper limit hole and lower limit hole, two spacer pins are inserted in the upper and lower limit hole, make a left side for the clamping block
Side is in contact with the outer edge surface of two spacer pins.
In above-mentioned technical proposal, it is from top to bottom evenly equipped with plurality of grooves in the vertical rails, in one of groove
A block is inserted with, the block protrudes from the leading flank of the vertical rails.
Since above-mentioned technical proposal is used, the utility model has following advantages compared with prior art：
1. by the way that pipettor is placed into rack in the utility model, vertical rails, sliding block and card are set in rack
Fitting, pipettor are slidably arranged in by shackle member and sliding block in vertical rails, in this way in pipetting processes, can pass through rotation
Shackle member adjusts the angle of pipettor, then is slided by sliding block, adjusts the height of pipettor, finally using supporting castor
It is moved, can ensure the stability in pipetting processes in this way, ensure liquid relief quality.
Description of the drawings
Fig. 1 is the structure diagram in the utility model embodiment one.
Wherein：1st, rack；2nd, pipettor；3rd, castor is supported；4th, vertical rails；5th, sliding block；6th, block；7th, Vertical Spring；
8th, clamping block；9th, spacer pin；10th, arc installation position；11st, upper limit hole；12nd, lower limit hole；13rd, groove.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and embodiments：
Embodiment one：It is shown in Figure 1, a kind of pipetting device, including rack 1 and the pipettor being set in rack 12,
1 bottom of rack is equipped with support castor 3, and vertical rails 4, sliding block 5 and shackle member, the sliding block 5 are additionally provided in the rack 1
It is slideably positioned in the vertical rails 4, on the sliding block 5, the pipettor 2 is installed on institute for the shackle member rotational installation
It states in shackle member；A Vertical Spring 7, the top of the Vertical Spring 7 are additionally provided in rack 1 right over the vertical rails 4
It is connected with 1 top of rack, bottom is connected with the top of the sliding block 5.
In the present embodiment, when in use, rack is pushed directly on, by the way that castor is supported to move, is moved to corresponding position
Locate, then operating personnel catch shackle member, and the pipettor in shackle member is driven to be moved down by sliding block along vertical rails, move
Moving needs at liquid relief, and liquid is adsorbed using pipettor, then unclamps the dynamics to shackle member, and Vertical Spring can be gradual
Sliding block drive is moved up, that is, pipettor is driven to move up, then rack is pushed at other positions by operating personnel, by liquid relief
Liquid in device is released, and completes liquid relief.Wherein, in pipetting processes, shackle member can rotate on sliding block, in this way can root
According to the different angle of imbibition, liquid is adsorbed, it is convenient and efficient.
Shown in Figure 1, the shackle member includes clamping block 8 and spacer pin 9, and 8 trailing flank of clamping block is equipped with one
Connecting shaft, the leading flank center of the sliding block 5 are equipped with a mounting hole, and the clamping block 8 is installed on described through connecting shaft rotation
In mounting hole；An arc installation position 10 is additionally provided on the leading flank of the clamping block 8, the arc installation position 10 connects the card
