Two utility model patents are equally attached, but both are authorized. Why?

There is a difference between "basically the same" and "the same", which should be mainly compared with the range of 1, such as the cylinder in the first one or the braking device and actuator in the second one, which is different from the patent protection range of the claims.

In addition, the examination of utility models is relatively loose, so there are many examples of slightly different authorizations.
