[0010] Preferably, there are a plurality of insertion openings, and the top of the inner wall of the insertion openings is chamfered.

[0011] Through the above structure, users can replace the fixing rings applicable to the outer walls of sampling tubes with different sizes according to the usage requirements, which preferably improves the practicability.

[0012] Preferably, a first card slot and a second card slot communicated with the insertion openings are respectively formed at the side walls of the plurality of installation grooves, and both the first card slot and the second card slot cooperate with the clamping blocks. Among them, the second card slot is obtained by rotating the first card slot by ° along the axis of the insertion opening.

[0013] With the above structure, the fixing ring can be rotated into the installation groove for limiting, so that the clamping block will be restricted and positioned in the up and down directions, thereby improving the connection stability.

[0014] Preferably, a groove is formed at the bottom wall of the installation groove, and a locking component is arranged at the groove, and the locking component is used to limit the clamping block in the first clamping groove.

[0015] With the above structure, the clamping block rotated into the first clamping groove is limited, preventing the first clamping groove from rotating back and disengaging from the first clamping groove, further improving the stability of the fixing ring.

[0016] Preferably, the locking component has a top block slidably arranged in the groove, and a spring is fixedly arranged between the bottom wall of the top block and the groove, and the spring is used to provide an elastic force for pressing the top block towards the top wall of the pipe rack body.
