The photoelectric encoder detects the rotation angle through the photoelectric conversion principle, and has the advantages of high resolution, high precision, high response speed and the like. When the output shaft of the motor 70 rotates, the photoelectric encoder can detect the rotation angle of the output shaft and feed back the information to the controller, and the controller can precisely control the motor 70 according to the received angle signal, so that the rotation angle of the motor 70 can be used to determine the position of the communication mechanism 8 and the relative position of the communication mechanism 8 and the concave hole 40, and the controller is used to determine the position according to the angle, which is not described in detail herein.
In one embodiment of the present application, as shown in fig. 5, 6 and 7, the communication mechanism 8 may include a first tube 80, a second tube 81, a first and second blocking plates 82 and 83, a torsion spring 84, two bushings 85, a push block 86 and a rubber head 87.

Specifically, in the initial state, the first rectangular array holes 800 and the second rectangular array holes 810 are mutually communicated, the first blocking plates 82 and the second blocking plates 83 are arranged in a cross staggered manner to seal the bottom end of the second pipe body 81, related personnel operate the sampling mechanism 9 to extract gas in a designated area, so that the gas remained before the sampling mechanism 9 is discharged through the first rectangular array holes 800 and the second rectangular array holes 810 on the side walls of the first pipe body 80 and the second pipe body 81, the air remained in the sampling mechanism 9 can be discharged by the newly extracted air due to the combined action of air pressure difference and the hydrodynamic principle, namely, when the new gas enters the sampling mechanism 9, the air pressure is increased, and the original residual air is pushed to be discharged through an outlet. This process is repeated continuously while the sampling mechanism 9 is continuously operating, and the introduction of new gas and the discharge of old gas are realized, so as to achieve the purpose of removing residual gas in the sampling mechanism 9, and ensure that the gas existing in the sampling mechanism 9 is the gas in the designated area.
