[0002] Stainless steel fasteners are a specific professional term that covers a wide range of products. Stainless steel fasteners are usually used to fasten more expensive machine parts because of their beauty, durability, and strong corrosion resistance. Common ones include bolts, nuts, clamps, etc.

[0003] According to a high-strength stainless steel fastener that is easy to disassemble, the device discloses a spiral ball and a hoop on a spiral screw rod that rise or fall under the rotation of the spiral screw rod. The rise of the hoop sleeve drives the expansion block to rise, and then the expansion block rises to squeeze the expansion groove to expand the expansion groove, so that the screw increases the contact area with the object to be fixed, and then the screw and the fixed object fit more closely. The spiral screw rod rotates in the other direction to make the expansion block fall to reduce the contact area with the expansion groove and no longer squeeze the expansion groove, so that the screw reduces the contact area with the object to be fixed, and then the fastener is easy to disassemble.

[0004] However, when the bolts of the device are installed and fixed, they need to be turned manually or with tools such as wrenches. When some bolts are tightened, the entire bolt needs to be placed in a fixing hole first, and then turned and fixed with a wrench or the like. At this time, a corresponding wrench needs to be inserted into the fixing hole to turn the bolt. Different bolts are used for different fastening points, and multiple wrenches need to be prepared for disassembly, which makes disassembly extremely inconvenient. Utility Model Content

At this time, a corresponding wrench needs to be inserted into the fixing hole to rotate the bolt, and different bolts are used for different fastening points. When disassembling, multiple wrenches need to be prepared, which makes disassembly extremely inconvenient.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: a high-strength stainless steel fastener that is easy to disassemble, comprising a bolt body, a disassembly mechanism is arranged outside the bolt body, and a protection mechanism is arranged outside the bolt body;

[0007] The disassembly mechanism includes a connecting groove, the interior of the connecting groove is rotatably connected to a rotating shaft, the exterior of the rotating shaft is clamped with a fixing column, a telescopic component is arranged on the inner side of the fixing column, a groove is opened at one end of the telescopic component, and a rotating block is slidably connected to the interior of the groove.

[0008] Preferably, the telescopic assembly comprises an adjusting slot, a telescopic rod is fixedly connected inside the adjusting slot, and a fixing block is fixedly connected to the top of the telescopic rod.

[0009] Preferably, the adjustment slot is opened at one end of the fixing column, and the bottom size of the fixing block is matched with the top size of the fixing column.

[0010] Preferably, the connection groove is opened at the top of the bolt body, and one end of the fixing column is set to be semicircular arc shape.

[0011] Preferably, the groove is formed at one end of the fixed block, and a limiting block is provided at one end of the rotating block.

[0013] Preferably, the gasket is fixedly connected to the bottom of the bolt body, the middle portion of the gasket is arranged to be through, and the rubber sleeve is sleeved on the outside of the bolt body.

[0014] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0015] When the bolt is to be removed from the bolt body, the bolt can be rotated to move it into the groove where it is needed to fix the bolt.

[0016] Secondly, the utility model sets a rubber sleeve which is sleeved on the outside of the bolt body, so that after the bolt body enters the fixing hole of the object, the rubber sleeve can fill the space between the bolt body and the fixing hole, making the bolt body tighter and improving the sealing performance, reducing the entry of rainwater, and then reducing the vibration of the bolt body by setting the gasket and spring washer, further improving the stability of the bolt body and avoiding loosening, thereby completing the protection operation.
