Safe convenient biological chemistry of high school experimental apparatus

The utility model discloses a chemistry technical field's of high school a safe convenient biological chemistry of high school experimental apparatus, including brassboard, bracing piece, connecting block and dead lever, the utility model discloses a dead lever and clamp be a plurality of test tubes of centre gripping simultaneously, convenient experiment, the problem that also can avoid handheldtest tube to exist simultaneously is safe convenient, water hole in the experimentation among the unrestrained liquid accessible experimental tank directly enters water storage tank, avoids tricklingdown to other places, the heating is placed the alcohol burner in spacing during the test tube, prevents the condition that the alcohol burner accident overturned, can make bracing piece and dead lever reciprocate through rotating the lift knob, rotary fixed rod makes the test tube slope to through the staple position, conveniently adjust the test tube position, the accessible is dismantled the connecting block and is dism
