Abstract

A tester incorporating an opening and closing mechanism includes a base (10), a cover (30) pivotably attached to the base, and a pair of master cylinders (40) pivotably attached to the base and cover. The base includes a top wall (12) and a control panel (18). Three spaced lower hooks (14) are formed on the top wall. A first sensor is mounted on one lower hook. A pair of actuators (16) is mounted behind two lower hooks. The control panel receives and sends signals. Three spaced upper hooks (34) are pivotably fixed on the cover, for engaging with the lower hooks respectively. A second sensor is mounted on the cover behind one upper hook. A third sensor (41a) is mounted on one master cylinder. The master cylinders and the actuators are controlled by the control panel, for opening and closing the cover.
