The invention discloses a navigator bracket adopting a vacuum sucker. The navigator bracket comprises the vacuum sucker, a sucker connecting rod, a navigator connecting rod and a fixation support used for fixing a navigator, wherein the vacuum sucker, the sucker connecting rod, the navigator connecting rod and the fixation support used for fixing the navigator are sequentially connected. A
flange is vertically arranged on the surface, opposite to an absorption end face, of the vacuum sucker, a through hole is formed in the
flange, the through hole is communicated with an absorption concave face, a sucker duct is arranged in the through hole, and a thread is arranged at an inlet end of the sucker duct; one end of the sucker connecting rod is inserted into the sucker duct by being matched with the thread, and is fixedly connected; a
piston is arranged at the
tail end, inserted into the sucker duct, of the sucker connecting rod; the
piston makes
reciprocating motion in the sucker duct. According to the navigator bracket adopting the vacuum sucker, the air in the vacuum sucker can be discharged outside by means of the
reciprocating motion of the
piston in the sucker duct, so that the adsorption capacity of the sucker is effectively improved; the navigator bracket adopting the vacuum sucker is simple in structure and convenient to operate, and can be repeatedly disassembled, thus being economical and practical.
