The utility model is convenient for operation with an external hexagonal wrench by setting the nut in a hexagonal shape, and at the same time, an arc surface is provided between two adjacent sides of the outer wall of the nut to facilitate the wrench to be inserted into the nut, and the arc surface is provided to avoid scratching the operator.

[0004] This patent sets the nut into a hexagonal shape to facilitate operation with an external hexagonal wrench, while most of the existing bolts do not have a sealing function. The screw has an external thread that cooperates with the internal thread of the nut to generate a tightening force. However, this structure allows the bolt to generate sufficient clamping force during the connection process, but cannot form an effective sealing interface and cannot avoid the problem of liquid or gas leakage. Therefore, we propose a new type of high-sealing bolt structure. Utility Model Content

[0007] Furthermore, the position and size of the sealing card block match the position and size of the card slot, and a snap-fit ​​connection is formed between the sealing card block and the card slot.

[0008] Furthermore, the position and size of the fixed block match the position and size of the slot, and the inner surface wall of the slot fits with the outer surface of the fixed block.

[0009] Furthermore, the fixing gasket is threadedly connected to the bolt body via an internal thread.
