Conical positioning bolt fastener

The utility model discloses a conical positioning bolt fastener. The device comprises a bottom plate, a threaded hole is formed in the top of the bottom plate, a mounting plate is arranged at the topof the bottom plate, the top of the mounting plate communicates with a conical sleeve, a conical rod is slidably connected into the conical sleeve, an outer hexagonal sleeve is fixedly connected to the top of the conical rod, and a first stud located in the conical sleeve is fixedly connected to the bottom of the conical rod. According to the utility model, the inner hexagonal sleeve drives the stud II to rotate; the stud II drives the clamping sleeve to move towards two sides through the transmission mechanism; finally, the clamping sleeve is used for limiting the stud I through the fixing mechanism; therefore, the conical positioning bolt has the advantage that the conical positioning bolt can be prevented from loosening easily when used alone; the conical positioning bolt solves the problem that when an existin
