[0002] The utility model patent with application number: CN202020761110.0 discloses a noise-reducing and anti-collision slider, including a slider body, dust-proof sheets are installed at both ends of the slider body, and anti-collision devices are provided at the left and right ends of the middle part of the outer side of the dust-proof sheet. The anti-collision device includes a buffer plate, a connecting seat, a first shock-absorbing spring and a second shock-absorbing spring. The connecting seat is fixedly installed on the dust-proof sheet, and the buffer plate is sleeved inside the connecting seat. The side of the connecting seat close to the dust-proof sheet is connected to the bottom of the buffer plate through the first shock-absorbing spring, and the other side of the connecting seat is connected to the bottom of the buffer plate through the second shock-absorbing spring.
