Embodiment

[0015] As shown in the figure, the emergency assault boat propeller protection device includes a connecting rod 1, three gear rods 2 are arranged at the end of the connecting rod, and the three gear rods are evenly spaced to form a fence, and serrated blades 3 are arranged on both sides of each rod.

[0016] The connecting rod and the gear rod form an L shape; the connecting rod is a telescopic sleeve rod, and one end of the connecting rod is movably connected to the bottom of the propeller 4 through bolts and nuts; the connecting rod extends out of the propeller blade 5 .

[0017] When in use, connect one end of the connecting rod to the bottom of the propeller through bolts and nuts, and the connecting rod extends out of the propeller blades to prevent scratches from touching the blades. During the driving of the assault boat, the propeller keeps rotating and the gear lever does not move. The blades on both sides of the gear lever will cut off the entangled foreign matter thr...
