This connecting part can fix two straws and control them through a single microcontroller. It can already install a microcontroller without using a ball joint or universal joint, so that two different straws can be used without a second microcontroller. The hydraulic system brings two suction tubes closer together and controls them without generating manual vibrations like conventional hydraulic microcontrollers. In addition, the positions of the two straws can be pre-set and can be remotely exchanged through a lever close to the operator. A special handle with two fixed straws, this is an advanced model for straw operation.
