Titration device for environmental protection detection

The utility model discloses a titration device for environmental protection detection, which relates to the technical field of titration devices, comprises a casing, and is characterized in that a titration component is arranged at the upper end of the casing in a sliding manner, a clamping component is fixedly arranged in the middle of the casing, and a rotating mechanism is fixedly arranged at the bottom of the casing. The third fixing block moves forwards or backwards together, the first connecting rod can rotate through the forward and backward movement of the third fixing block, the fourth fixing block at the other end can abut against the second connecting rod through the rotation of the first connecting rod, the second connecting rod is promoted to rotate, and therefore the effect of clamping the fixed bottle is achieved; the problem that in the prior art, fixing bottles of different specifications cannot be adapted is solved, the problem that the experiment bottle is not stable enough during titration
