The application discloses an anti-squeezing safety device of a horizontal sliding door, wherein the horizontal sliding door comprises a door plank and a door cover, wherein clearance is disposed between the door plank and the door cover; and the anti-squeezing safety device is located inside the door cover and comprises a baffle, a reset mechanism and a trigger switch. The baffle is a part of or the whole part of the turning corner on the door cover which is closest to the clearance, the baffle is fixed on the side face inner wall of the door cover by the reset mechanism, and the baffle is rotated to inside of the door cover with the reset mechanism as the axis when being pressed. A torsional spring is disposed inside the reset mechanism and used to recover the non-squeezed baffle to a position before rotation. The trigger switch is fixed on the side face inner wall of the door cover; and the trigger switch comprises two states, wherein the non-squeezed baffle makes the trigger switch stay at a first state, and the squeezed baffle makes the trigger switch stay at a second state. The anti-squeezing safety device of the horizontal sliding door disclosed by the application can timely find and stop a squeezing damage and stop, can prevent wrong operations and can also avoid instant damages and pain feelings generated to fingers and other parts.
