[0039] The working principle of the utility model is as follows: after the sample bottle 2 is placed in place, when opening the cover, the clamping jaw assembly 3 is pushed up by the clamping jaw push rod 54 by the clamping jaw motor 51 so that the clamping jaw assembly 3 is closed and clamps the sample bottle body 21, and then the sample bottle cap 22 is limited and clamped by the manipulator, and the first synchronous wheel 41 is driven by the capping motor 44 to rotate the sample bottle body 21, so that the sample bottle cap 22 and the sample bottle body 21 are loosened and separated. When closing the cover, the capping motor 44 reverses and drives the first synchronous wheel 41 to tighten the sample bottle cap 22 and the sample bottle body 21. When the clamping jaw motor 51 pulls down the clamping jaw push rod 54, the clamping jaw assembly 3 opens and the sample bottle 2 can be taken away. The above process can complete the opening and closing operations of the sample bottle 2 by reciprocating, without manual execution and intervention.
