The bolt 18 is moved to make it conflict with the limit groove 22, so that the long handle bar 19 is locked to prevent the anti-collision alarm 20 from sliding left and right, and then the blocks 16 at both ends of the long handle bar 19 are naturally inserted into the card groove 15. At this time, the rangefinder can detect the distance to a point above the test tube. When the experimenter forgets to take off the test tube cap, the rangefinder detects the obstacle and transmits the signal to the single-chip microcomputer. The single-chip microcomputer controls the alarm to send an alarm prompt to the experimenter, and the experimenter can take off the test tube cap in time to avoid the sample needle in the test tube from being damaged.
