You will have to post all part files. You cannot just post an assembly file as it LINKS all parts and sub-assemblies together. I didnt look close at the picture, do you have a fully defined (fully constrained) component such as the base of the jack? Or, do you have a component grounded such as the base of the jack to keep it from moving? Or is there a different component that is fixed in space that is causing the unwanted movement?

Expand the "Origin" folder of the assembly and you'll  see 3 planes.

Each part has the same "Origin" folder.

Constrain the part you want to "fix"/"ground" with those 3 planes.

Usually the first part you add in the assembly will be grounded at origin.

Right Click on the base part, (The part you wish to stay in position.) then select Grounded.

thanks for all comments. i was find solution. my first object wasn't grounded automatically. problem solved in ground and root options

Hi! If you prefer having the first component to be grounded, go to Tools -> App Options -> Assembly -> check "Place and ground the first component on placement."

Many thanks!
