Design Principle
The working principle and application process of this design: when the design is in use, the knobs on both sides of the support base are slightly rotated outward, the contact end of the knob and the support rod are separated from each other, and the extrusion force disappears. The support rod is in an active state. Pull the support rod and grip rod outward, and the support rod and grip rod rotate outward, and the bottom side of the support rod fits with the No. 1 limit block at the center of the surface of one side of the support seat, No. 1 limit block supports and limits the supporting rod. The supporting rod and the holding rod are inclined at a certain angle, and the knobs on both sides of the support base are slightly rotated inward. The end of the knob and the support rod are squeezed each other, and the support rod is in a fixed state. The rotating plate at the upper end of the connecting seat is put down to fit the wall surface, the rotating shaft at the connection between the bottom end of the rotating plate and the connecting seat is rotated. The rotating plate turns to the bottom side, and the rotating plate is placed vertically with the wall.
