The 竖锯盒子 are a Prop featured in Dead by Daylight 
that was added with Patch 1.9.0
Overview
A Jigsaw Box on The Game
Billy on the TV set next to a table with Sketches of Reverse Bear Traps.
竖锯盒子 are a way for Survivors 
to try to get rid of Reverse Bear Traps that The Pig 
has put on their heads.
Each Map that features The Pig as the Killer spawns with a set number of 竖锯盒子. The Pig can alter this number by using certain Add-ons 
for her Power.
They give off distinct sound cues of moving mechanical parts.
Billy, the Jigsaw Puppet
竖锯盒子 are easily recognised due to the presence of "Billy", Jigsaw's Puppet, who sits atop of each Box.
He can also be seen on the TV sets featured throughout The Game.
Usage
A randomly chosen Jigsaw Box will be the Key to unlocking the Reverse Bear Traps, the others serve as decoys. Each Trap will have its Key hidden in a randomly selected Box.
A Survivor with a Reverse Bear Trap on their head will see the Aura of all available 竖锯盒子, unless The Pig has Rules Set No.2 
equipped. Interacting with the boxes will trigger Skill Checks 
. Failing these Skill Checks will give a progress penalty and a Loud Noise Notification for The Pig, similar to a failed Hook Sabotage. By default, searching a box takes 12 seconds.
Once the progress bar is full, either of two things will happen depending on whether or not it was the correct Jigsaw Box:
Correct Jigsaw Box
- The Reverse Bear Trap will be removed from the Survivor's head and be gone for good.
Wrong Jigsaw Box
- Jigsaw's puppet, "Billy", will laugh at the Survivor and the Reverse Bear Trap remains on the Survivor's head.
- The Survivor will have to search for another Jigsaw Box and try their luck anew.
- The Box's white Aura will no longer be shown to the Survivor, only those of the remaining ones.

Change Log
Patch 2.5.0
- Added a minimum spawn distance in-between Chests
to no longer cause 竖锯盒子 to spawn too close together.
Trivia
- In the Game files 竖锯盒子 are also being referred to under the name Puzzle Box.
- The presence of 竖锯盒子 on a Map reveal The Pig's identity to Survivors in a similar fashion as do The Trapper's Bear Traps.
- Despite being a notable icon of the SAW™ franchise, this is the only appearance of Billy in the Chapter DLC.
- He does not appear on any Perks or Add-ons exclusive to The Pig.
10 Pints of Sacrifice Trap
- The 竖锯盒子 are most likely inspired by the 10 Pints of Sacrifice Trap featured in SAW V. They have a similar look and some of the Add-ons affecting the 竖锯盒子 point to a similar use.
- This Trap required the Victims to "donate" 10 Pints of their own blood within 15 minutes, to unlock a door or they would be killed by nail bombs located in the room. Inside the Trap, circular blades would cut open the Victims' hands and collect the blood in a glass beaker below.
