Anti-collision buffering device for protecting aluminum guide rod

The utility model discloses an anti-collision buffering device for protecting an aluminum guide rod, which comprises a pressure-disengaging machine and two anti-collision buffering mechanisms symmetrically arranged on the pressure-disengaging machine, each anti-collision buffering mechanism comprises a support and a multi-layer buffering assembly, the support is connected with the top of the pressure-disengaging machine, each buffering assembly comprises two cantilevers arranged at intervals, and the cantilevers are connected with the pressure-disengaging machine. One ends of the cantilevers are fixedly connected with the support, the other ends of the cantilevers are suspended, a buffer roller is arranged between the two cantilevers, the two ends of the buffer roller are slidably connected with the two cantilevers through connecting shafts respectively, and a plurality of springs are evenly distributed between the buffer roller and the support. The device is simple in structure and convenient to use, can pre
