Claim 3:
4. A suction cup type hook, comprising:
a hook body,
a suction cup,
a spring, and
a rotatable button; wherein
the hook body defines a mounting cavity opened toward a rear side and defines a connecting hole connected to the mounting cavity and arranged on a front side;
the suction cup comprises a flexible deformation portion and a connecting rod extending forward from a middle of the flexible deformation portion, the flexible deformation portion being disposed on the rear side of the hook body; the connecting rod extends out of the mounting cavity through the connecting hole;
the spring is sleeved on the connecting rod; an end of the spring is connected to an inner wall surface of the mounting cavity, and the other end of the spring is connected to a front side of the flexible deformation portion;
the rotatable button is disposed on the front side of the hook body, and the rotatable button is rotatably connected to a front end of the connecting rod and has a lifted state and a snapped state relative to the hook body;
in the lifted state, the flexible deformation portion is in a relaxed state and is separably arranged with an edge of the mounting cavity; when the rotatable button is pressed to switch to the snapped state;
the rotatable button pulls the middle of the flexible deformation portion to protrude forward by the connecting rod, an edge of the flexible deformation portion abuts against the edge of the mounting cavity, and a rear side of the flexible deformation portion forms a concave arc;
the hook body comprises a mounting base; the mounting base comprises a panel; the panel is bent in a step shape to form a rotation limit table disposed in a lower part and a rotation limit cavity disposed in an upper part; the connecting hole is opened on a front side of the rotation limit cavity; in the snapped state, the rotatable button is disposed in the rotation limit cavity;
an outer edge of the panel is rounded, an upper side of the rotation limit cavity is set horizontally, and a shape of the rotatable button is adapted to the rotation limit cavity in a fan-shaped structure;
a chamfer is formed between an upper part of an outer periphery of the rotatable button and a rear side of the rotatable button, and the chamfer is enclosed with the front side of the rotation limit cavity to define an operating slot.
