If the utility model patent is accepted and the patent certificate is issued, does it mean that the search has also passed? This patent means that it has legal effect.

After the certificate is obtained, it proves that it has legal effect. The utility model and design have not been substantially examined, so it is not excluded that their technical schemes are the same. However, if there is a legal dispute over your patent certificate, the other party can apply for your patent invalidation procedure. Generally speaking, if only one quantity is required for the declared project, it is no problem to use this. If enterprises want to pursue quality and economic benefits, it is better to apply less, because patent rights are unstable. It may be invalidated by others.
