Suction holder
First Claim
1. A suction holder, comprising:
- a suction unit comprising a suction cup and a traction element engaging a central portion of a top surface of the suction cup, the central portion of the top surface of the suction cup being raised and being bordered by a peripheral portion of the top surface of the suction cup;
a housing unit comprising an upwardly raised central portion and disposed with a passage hole for the traction element to pass therethrough;
a pressure deformable unit located on the suction cup and confined in the housing unit, the pressure deformable unit having a circumference radially distributed with a plurality of elastic pressing elements, a top of the pressure deformable unit being in contact with an inner wall of the housing unit, and the plurality of elastic pressing elements pressing on the suction cup;
a spring located between the pressure deformable unit and the suction cup, the spring surrounding a periphery of the traction element and having a first portion that surrounds the central portion of the top surface of the suction cup and a second portion that contacts the peripheral portion of the top surface of the suction cup; and
a linkage positioning unit located on the housing unit and comprising projections inserted into guiding slots of the traction element of the suction unit, the linkage positioning unit operable to drive the traction element to move upward and be locked in a raised position by pulling the linkage positioning unit downward to pivot the linkage positioning unit about the projections until a free distal end portion of the linkage positioning unit contacts an outer surface of the housing unit, and the linkage positioning unit operable to release the traction element from the raised position by pulling the linkage positioning unit upward to pivot the linkage positioning unit about the projections to separate the free distal end portion of the linkage positioning unit from the outer surface of the housing unit;
wherein the linkage positioning unit has an outer contour such that, when the free distal end portion of the linkage positioning unit is in contact with the outer surface of the housing unit, the outer contour of the linkage positioning unit conforms to an outer contour of the housing unit.

Abstract
A suction holder includes a suction unit, a housing unit, a pressure deformable unit, and a linkage positioning unit. The suction unit includes a suction cup and a traction element engaged to a top of the suction cup. The pressure deformable unit has a circumference radially distributed with a plurality of elastic pressing elements. The pressure deformable unit is located on the suction cup and is confined in the housing unit. The linkage positioning unit can drive the traction element to move upward so that the suction cup can attach to a surface. When the surface is curved or has arcs, the elastic pressing elements can be deformed to different extents to be pressed on the suction cup to maintain better attachment to the surface.
