Could you please tell me what the meaning of "pull up her(or his) smile" is?
Sadie trembled for the entire ride, but she pretended to be enjoying herself, restoring her lipsticked smile every time he glanced in her direction.
At the next rehearsal, Charles asked Sadie about a scene, and Shawn saw
them talking. Sadie came over a few minutes later but Shawn wouldn’t
speak to her. He turned his back and she left crying.
“What’s that about?” I said.
“Nothing,” he said.By the next rehearsal, a few days later, Shawn seemed to have forgotten
it. Sadie approached him warily, but he smiled at her, and a few minutes
later they were talking and laughing. Shawn asked her to cross the street
and buy him a Snickers at the dime store. She seemed pleased that he
would ask and hurried out the door, but when she returned a few minutes
later and gave him the bar, he said, “What is this shit? I asked for a Milky Way.”
“You didn’t,” she said. “You said Snickers.”
“I want a Milky Way.”
Sadie left again and fetched the Milky Way. She handed it to him with a
nervous laugh, and Shawn said, “Where’s my Snickers? What, you forgot
again?”
“You didn’t want it!” she said, her eyes shining like glass. “I gave it to
Charles!”
“Go get it.”
“I’ll buy you another.”
“No,” Shawn said, his eyes cold. His baby teeth, which usually gave him
an impish, playful appearance, now made him seem unpredictable, volatile.
“I want that one. Get it, or don’t come back.”A tear slid down Sadie’s cheek, smearing her mascara. She paused for a
moment to wipe it away and pull up her smile. Then she walked over to
Charles and, laughing as if it were nothing, asked if she could have the
Snickers. He reached into his pocket and pulled it out, then watched her
walk back to Shawn. Sadie placed the Snickers in his palm like a peace
offering and waited, staring at the carpet. Shawn pulled her onto his lap
and ate the bar in three bites.

As in any language, English writers are going to make up metaphors that are not common idiomatic expressions. In this case "pull up her smile" suggests she's forcibly lifting the corners of her mouth into a smile, even though she doesn't feel like smiling at all.
If you can't find an expression in the dictionary or by searching online, assume it's something the writer made up and use the context to figure out what is meant -- the same as any native speaker would do. Make an "educated guess" and see if it fits.
