[0021] Embodiment 1

[0022] like Figure 1-Figure 4 As shown, the utility model proposes a fastening sleeve that is easy to disassemble, including a fastening sleeve 1, a metal washer 3 and a nut 5. The outer surface of the fastening sleeve 1 is provided with an insertion opening 7, and the inner wall of the metal washer 3 is provided with a limiting protrusion 8. The limiting protrusion 8 and the metal washer 3 are integrally processed, and the limiting protrusion 8 is inserted into the insertion opening 7 to limit the rotation of the metal washer 3. An annular limiting protrusion 2 is provided on the outer surface of the fastening sleeve 1 near the lower surface, and the bearing is installed between the annular limiting protrusion 2 and the metal washer 3. A threaded groove 6 is provided on the outer surface of the fastening sleeve 1 near the upper surface, and the nut 5 is fixed to the fastening sleeve 1 through the threaded groove 6. A plurality of fixing sockets 9 are equidistantly provided in a circular array near the edge of the outer surface of the metal washer 3.

[0023] The outer surface of the nut 5 is provided with a number of bite grooves 4 equidistantly in a circular array. The setting of the bite grooves 4 facilitates the use of a hook-type torque wrench to tighten the nut 5. The outer surface of the nut 5 is symmetrically provided with a receiving groove 11 and a through slide groove 13 at both sides, and the receiving groove 11 and the through slide groove 13 are connected. The receiving groove 11 extends horizontally from the outer surface of the nut 5 toward the axial direction, and the through slide groove 13 extends from the upper surface to the lower surface of the nut 5. Springs 12 are fixedly connected to the inside of the two receiving grooves 11, and the ends of the two springs 12 are fixedly connected to slide rods 16. Sliding plates 18 are slidably installed in the inside of the two through slide grooves 13, and the outer surfaces of the two sliding plates 18 are provided with fixing holes 15.

[0024] When the utility model is in use, when the nut 5 is sleeved on the fastening sleeve 1 and tightened, and after the sliding plate 18 and the fixed socket 9 are aligned, the sliding plate 18 is pushed to insert one end of the sliding plate 18 into the fixed socket 9, and the elastic force of the spring 12 causes the end of the sliding rod 16 to be away from the spring 12 and inserted into the fixed hole 15, while locking and fixing the sliding plate 18, the nut 5 is also locked to prevent the nut 5 from loosening. When the nut 5 is removed, the sliding rod 16 is pressed to separate it from the fixed hole 15, and the sliding plate 18 is pushed in the opposite direction to separate the sliding plate 18 from the fixed socket 9, so that the metal washer 3 can be released from the fixation of the nut 5.
