Description

Technical Field

[0001] The utility model relates to the technical field of nuts, in particular to a nut which can be locked manually. Background Art

[0002] The working principle of the nut is to use the friction between the nut and the bolt for self-locking, but the reliability of this self-locking will be reduced under dynamic loads. In some important occasions, we will take some anti-loosening measures to ensure the reliability of the nut locking.

[0003] The existing nuts are usually tightened by using a wrench or pliers during use. When there is no wrench or pliers around, the existing nuts are difficult to tighten manually due to their smooth outer surface and small size, and are less practical. Utility Model Content
