1. A hoisting device, comprising:
a base;
a hoisting beam;
a first strut group and a second strut group between the base and the hoisting beam, the first strut group and the second strut group respectively comprising a first strut and a second strut, a first end of the first strut and a first end of the second strut being pivotally connected at a pivot point, and a second end of the first strut and a second end of the second strut being respectively pivotally connected to the hoisting beam and the base; and
an actuating device, the actuating device synchronously providing force at the pivot points of the first strut group and the second strut group to change an angle between the first strut and the second strut of the first strut group and the second strut group so that the hoisting beam is lifted or lowered,
wherein the base has a U-shaped groove,
wherein the first strut group, the second strut group and the actuating device are accommodated in the U-shaped groove of the base,
wherein the actuating device comprises a first actuator for the first strut group and a second actuator for the second strut group,
wherein the first actuator and the second actuator synchronously operate to provide the force at the pivot points of the first strut group and the second strut group, and
wherein the first actuator or the second actuator comprises:
a lead screw driven by an electric motor arranged in the base;
a screw nut matching the lead screw, the screw nut being driven by the lead screw to move horizontally; and
a push rod, a first end of the push rod being pivotally connected to the screw nut, and a second end of the push rod being pivotally connected at the pivot point of the first strut group or the second strut group.
