Labor saving device
Abstract:
A device to handle and manage a heavy screen includes a supporting module, a connecting module, two first resilient members, and two second resilient members. The connecting module includes a mounting rod provided with a pulling rod at a middle portion, and two pivot rods rotatably installed on one end far away from the mounting rod of the pulling rod. Each first resilient member is connected to an end of the top plate, and each second resilient member is connected to an end of the bottom plate and one end of a pivot rod. The two first resilient members are stretched when screen is pulled down, and each pivot rod rotates relative to the pulling rod to pull the two second resilient members when screen is lifted. The screen is effectively weightless, enabling static positioning of the screen.
