Abstract

The invention discloses a multi-point equidistant adjustment device, which comprises a left baffle and a right baffle, a cylinder body is fixedly connected between the left baffle plate and the right baffle plate, and a conductive spring is arranged in the cylinder body. The left end of the conductive spring is fixedly connected with a first limiting block, the inner wall of the cylinder is provided with a first limiting groove slidingly connected with the first limiting block, the right end of the conductive spring is fixedly connected with the right baffle plate, The conductive spring is electrically connected to a built-in power supply through a potentiometer, and the conductive spring is provided with multiple turns. The advantages are: set the cylinder body, the first limit block, the first limit groove, the second limit block, the second limit groove, the conductive spring and the variable resistance device, adjust the resistance of the potentiometer according to the specific situation, and then change The current intensity in the circuit formed by the potentiometer, the conductive spring and the built-in power supply can then change the shrinkage degree of the conductive spring, and the distance between every two coils of the conductive spring can change the distance between multiple liquid-taking needles, which has strong applicability.

Description

technical field [0001] The invention relates to the technical field of biological experiments, in particular to a multi-point equidistant adjustment device. Background technique [0002] In the field of biological experiments, it is often necessary to use a pipetting device to transfer a certain volume of experimental solution. Current pipetting devices include single-channel and multi-channel. When using a multi-channel pipetting device to suck and push out the experimental solution, sometimes it is necessary to adjust the equidistant distance of multiple pipetting needles. The existing pipetting device uses multiple driving devices to adjust the distance between multiple pipetting needles, which is cumbersome and has errors. [0003] In order to solve the above problems, we propose a multi-point equidistant adjustment device. Contents of the invention [0004] The object of the present invention is to propose a multi-point equidistant adjustment device in order to sol...
