[0014] Compared with the prior art, the utility model provides a liquid transfer workstation with a clamping claw, which has the following beneficial effects:

[0015] 1. This kind of pipetting workstation with clamping claws, through the moving mechanism installed inside the shell, the first screw rod and the second screw rod can be rotated under the action of the second motor of the moving mechanism, so that the mounting seat can drive the liquid collection needle and the clamping claw mechanism to move horizontally and forward and backward, and at the same time, the liquid collection needle and the clamping claw mechanism can be driven to move vertically under the action of the electric telescopic rod, so as to achieve the effect of flexible pipetting, and at the same time, the clamping claw mechanism can also move synchronously and flexibly, so the second screw rod can be rotated under the action of the third motor of the clamping claw mechanism, and then the clamping plate can be driven to move through the fixed block to take the empty test tube that has completed the pipetting out of the placing mechanism and send it out of the device. Therefore, when the device is in use, since the pipetting workstation has a clamping claw structure, the practicability and use effect of the workstation can be effectively improved.

[0016] 2. This kind of pipetting workstation with a clamping claw has a first motor and a first screw installed inside the frame. The first screw can be rotated under the action of the first motor. Since the first screw is threadedly connected to the connecting block, the placement plate can be driven to move through the connecting block, so that the placement plate can be moved out of and into the interior of the shell. Therefore, when the device is in use, it is more convenient to install a test tube containing liquid, thereby effectively improving the working efficiency of the workstation.
