The bracket 17 drives the magnifying glass 21 to move. Stop turning the second handle 15 when it moves to the required position. Then, turn the third handle 26 according to the angle of the experimenter. The third handle 26 drives the second worm 18 to rotate on the bracket 17. The second worm 18 drives the second worm gear 19 to rotate. The second worm gear 19 drives the third rotating shaft 20 to rotate on the bracket 17. The third rotating shaft 20 drives the magnifying glass 21 to rotate, thereby completing the angle adjustment of the magnifying glass 21. It is suitable for the experimenter to use the magnifying glass 21 to better observe and inject the vein during guinea pig intravenous injection, thereby improving the success rate of intravenous injection. By turning the second handle 15 and the third handle 26, the experimenter can conveniently adjust the position and angle of the magnifying glass 21 for better observation.
