When the crack of the pavement is a straight crack or the bending radian of the crack is smaller, the anti-cracking plaster 400 is stuck along the trend of the crack by holding the first handle 103 and the second handle 104 with both hands. When the bending radian of the pavement crack is larger, the second handle 104 is manually driven to pull along the bending direction of the pavement crack, so that the radian formed by the bending mechanism 300 is the same or approximately the same as the bending radian of the pavement crack, and then the anti-cracking patch 400 is stuck along the trend of the crack.
The bending radian of the pavement crack can be adapted through the bending mechanism 300, so that the anti-cracking patch 400 can be adapted to the bending radian of the pavement crack, and further the anti-cracking patch 400 is tightly attached to the pavement.
