Description

Technical Field

[0001] The utility model relates to the technical field of stepped pin assemblies, in particular to a novel stepped pin assembly. Background Art

[0002] The stepped pin assembly is a specially designed pin with a main body that presents a cylindrical structure with multiple sections of different diameters. These sections of different diameters are called steps. This design enables the stepped pin assembly to adapt to different assembly clearances and positioning requirements, achieving more precise and stable connection and fixation.

[0003] When using a stepped pin to fix an object, the stepped pin is usually inserted into the fixing hole to a certain position according to the size of the fixing hole on the object, so that the corresponding section is stuck in the fixing hole, and finally the plug is inserted into the corresponding hole on the stepped pin to limit and fix it. However, since the plug is not fixed again after being inserted into the hole on the stepped pin, when the limited object vibrates for a long time, the plug may loosen and fall off from the hole, causing the stepped pin to loosen and fall off, thereby reducing the fixing effect and affecting the use of the object.
