Rapid assembly and disassembly tool for double-end stud

The utility model provides a rapid assembly and disassembly tool for a double-end stud. The tool is composed of a connecting sleeve, a cylindrical sleeve, a movable threaded block, adjusting screws, a sliding screw, a compression spring and a connecting screw. In the assembly process, one end of the double-end stud completely enters in the cylindrical sleeve through rotating the tool sleeve; the two adjusting screws are rotated so that the movable threaded block can move into the cylindrical sleeve to be matched with fixing threads inside the cylindrical sleeve, and the threaded part of the stud is sufficiently compressed and locked; a ratchet wrench is connected with the square opening of the connecting sleeve and rotated to drive the connecting sleeve to rotate, so that the double-end stud is driven to screw into or screw out. After assembly and disassembly, the adjusting screws are loosened, the movable threaded block retracts under the action of the compression spring, and therefore the tool is separated from the stud. The tool integrates assembly and disassembly, can rapidly assemble or disassemble the double-end stud, can avoid thread damage, lower the labor intensity and improve working efficiency, and is high in adaptability and wide in application range.
