Abstract
An adjustable positioning device includes a connection member, a positioning member and an adjusting member threaded onto the connection member and an adjustment structure including two protrusions respectively located on the positioning member and the adjusting member to face toward each other and an abutment surface extending upwardly and circularly from the bottom side of one protrusion toward the other protrusion. Subject to the design of the adjustment structure, the user can conveniently adjust the position of the positioning component set on the connection member to produce a positioning effect, or a positioning and tamper-proof effect.
Claims1
An adjustable positioning device, comprising:
- a connection member comprising an outer thread and a head at one end of said outer thread;
- a positioning component set comprising a positioning member and an adjusting member respectively threaded onto said outer thread of said connection member, said positioning member being disposed adjacent to said head of said connection member, said adjusting member being disposed at one end of said positioning member remote from said head;
- and
- an adjustment structure comprising two protrusions and at least one abutment surface, said two protrusions being respectively located on said positioning member and said adjusting member of said positioning component set to face toward each other, each said abutment surface extending upwardly and circularly from a bottom side of one said protrusion toward the other said protrusion;
- wherein when rotating said adjusting member on said connection member toward said head after said two protrusions are abutted against each other, said positioning member is forced to rotate toward said head;
- when rotating said adjusting member on said connection member in direction away from said head after said two protrusions are abutted against each other, one said protrusion is moved into abutment against one said abutment surface to eliminate the screw pitch between said positioning member, said adjusting member and said outer thread, achieving a positioning effect.
