Test tube carrying device for water quality detection

The utility model relates to the technical field of water quality detection, and discloses a test tube carrying device for water quality detection, a lifting electric push rod is installed in the middle of a support of a supporting underframe, a carrying platform is installed at the telescopic end of the lifting electric push rod, and a butt clamp transmission mechanism is installed in a box frame of the carrying platform. And two groups of clamping arm fixing mechanisms are symmetrically arranged above racks of the two groups of track sliding tables in the butt clamping mechanism. By means of butt-clamping transmission of the butt-clamping transmission mechanism, the front clamping arms and the rear clamping arms in the two sets of clamping arm fixing mechanisms can be pushed to conduct butt-clamping fixing on a containing frame in a front-back butt-clamping mode, and then the left-right butt-clamping mode of the left clamping arms and the right clamping arms in the clamping arm fixing mechanisms is controll
