Claim 0:
1. 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 an annular wall;
the annular wall comprises a first compression ring and a second compression ring that are arranged concentrically from inside to outside: in the snapped state, the first compression ring and the second compression ring respectively abut against the edge of the flexible deformation portion.
