Support frame

A support frame, suitable for supporting an electronic body, the support frame comprising:

• a movable element, comprising a body and a cam structure, wherein the cam structure is located on one end of the body, and the end is pivotally connected to the electronic body based on a pivot axis and located within the electronic body, the cam structure comprises a first convex portion and a second convex portion disposed around the pivot axis;
• an elastic element, disposed in the electronic body and comprising a plurality of elastic pieces separated from each other;
• and
• a limiting element, disposed in the electronic body, and the limiting element comprising a plurality of pins separated from each other and disposed along an axial direction of the pivot axis, wherein the pins are respectively located on the elastic pieces, a rotational resistance of the movable element relative to the electronic body when the pins are slidably engaged against the first convex portion is different from a rotational resistance of the movable element relative to the electronic body when the pins are slidably engaged against the second convex portion.
