Patent attributes
A portable electronic apparatus including a base, a screen and a withdrawer is provided. The screen is pivotally connected to the base and the withdrawer is adopted for assembling to the base. The withdrawer includes a case, a combination lock and a push rod. The case, on which the combination lock is disposed, has an opening for exposing a part of the combination lock. The push rod disposed on the case has a first and a second end, wherein the second end is connected with the combination lock. When the combination lock is locked, the first end of the push rod penetrates through the base so as to fix the relative position between the case and the base; and when the combination lock is unlocked, the first end of the push rod can be withdrawn back into the case to separate the case from the base.
