[0006] Furthermore, a step portion for supporting the support plate is disposed on the inner wall of the opening end of the rectangular box body, and a clamping member for fixing the support plate on the step portion is disposed at the opening of the rectangular box body.

[0007] Furthermore, the clamping member includes an L-shaped plate, the end of the L-shaped plate is provided with a clamping plate which is inserted into the rectangular box body and rests against the inner surface of the support plate, the inner wall of the vertical section of the L-shaped plate is provided with a clamping strip, and the outer wall of the rectangular box body is provided with a clamping groove which cooperates with the clamping strip.

[0008] Furthermore, the telescopic part is a telescopic cylinder; or the telescopic part includes an outer sleeve and an inner sleeve sealed to each other, the inner wall of the outer sleeve is provided with a sealing structure cooperating with the outer wall of the inner sleeve; the top of the outer sleeve is connected to the bottom side of the support sleeve.

[0009] Furthermore, a support ring is arranged inside the outer sleeve, the bottom side of the support ring is connected to a spring, and the end of the spring is against the bottom side of the inner sleeve.

[0010] Furthermore, the sealing structure is a sealing fin or a sealing ring.

[0011] Furthermore, a threaded hole is provided on the bottom side of the inner sleeve, and an adjusting bolt is threadedly connected to the threaded hole. One end of the adjusting bolt passes through a through hole at the bottom of the support sleeve and extends into the support sleeve, and the end portion abuts against a movable block sliding along the support sleeve.

[0012] The utility model has the following beneficial effects:

[0013] The utility model arranges a supporting structure under any PCR tube insertion hole, and the supporting structure is raised and lowered according to demand during use. Therefore, when the PCR eight-tube strip needs to be pulled out from the PCR tube insertion hole, the multiple supporting structures supporting the PCR eight-tube strip are first controlled to be lifted up synchronously, thereby completing the overall upward lifting of the PCR eight-tube strip. At this time, the PCR eight-tube strip can be easily pulled out from the PCR tube insertion hole, thereby preventing the PCR eight-tube strip from being stuck at the PCR tube insertion hole during the pulling out process.
