Pipette convenient to use

The utility model discloses a pipette convenient to use, relates to the technical field of measuring instruments, solves the problem that a traditional pipette cannot accurately draw liquid during use, and comprises a pipette and a liquid drawing device which is propped against a pipe orifice at one end, far away from liquid to be drawn, of the pipette, the liquid drawing device comprises a pipe body and a piston connecting rod mechanism which is arranged in the pipe body and is used for drawing air in the pipette, and an air inlet valve which is used for controlling the amount of air sucked by the piston connecting rod mechanism is fixedly connected in the pipe body. According to the pipette, the piston connecting rod mechanism is matched with the air inlet valve, so that the liquid suction device propped against the pipette can properly suck air in the pipette, and the pipette can suck a proper amount of liquid in batches by utilizing the pressure difference. 本申请公开了一种便于使用的移液管，涉及量出式仪器的技术领域，改善了传统移液器在使用时不能较为精确
